Full textAbstract:
The number and diversity of aquarium display facilities has grown considerably in the past few years. This is, in part, because the aquarium operating model has allowed a certain economic independence. This article examines the enhanced revenue earning potential of aquariums. It compares aquarium financial factors with zoos and other cultural organizations, which normally require an annual government contribution for operations. As an industry, aquariums have considerable drawing power, are smaller in size when compared to zoos and are efficient to operate. These factors contribute to financial viability—an important element in sustaining modern aquarium's work in public education, research and conservation. As the number and diversity of Aquariums grows, more people are exposed to the underwater world and its many conservation issues. Aquariums do not limit their audience to the experts, they allow anyone to experience and learn about the oceans, rivers and streams of the world. To meet future demands, the financial sustainability of aquariums must be continually strengthened to ensure continued future public awareness.

Full textAbstract:
Community-based capture–hold–release (CHR) aquariums were developed to (i) increase community connection to local marine environments by displaying local animals, (ii) avoid negative perceptions about holding animals by minimizing the time any individual is held captive, and (iii) operate with a low ecological footprint. CHR aquariums in British Columbia, Canada, require government-issued licences and permits to capture, hold, and release animals, a condition of which is that neither capture nor release can result in negative ecological, genetic, or disease impacts on wild populations in the collecting or receiving waters. Growth in the popularity of CHR aquariums is placing them under greater scrutiny from permitting agencies. Because of variability between facilities and a lack of performance standards, CHR aquariums cannot be assured of a consistent assessment. This paper proposes a CHR Aquarium Health Program that transparently and consistently provides assurances that they are socially and ecologically safe and recognizes the unique challenges of small-scaled, often rural aquariums. The value of this approach is discussed with respect to 10 years of implementation at the Ucluelet Aquarium.

In the modern world, a monitoring system for an automated aquarium is not a novel concept. The device enables automatic pH, temperature, and turbidity level, water level, andfish nutrition management for the user. Manually examining an aquarium's conditions, however, would be inconvenient. It takestime, and dedication is needed. Here, a system connected to the Internet of Things (IoT) is presented to monitor and control the entire aquarium up keep utilizing electronics and sensors that continuously communicate and report real-time status to usersmartphones. The created system will keep track of any physical alterations to the water and maintain it at its perfect state, deciding on any necessary adjustments automatically. The aquarium will carry out all tasks automatically, including controlling the water level, feeding, pH, turbidity, and temperature. It will lessen the amount of manual work needed to manage aquariums.

Full textAbstract:
The aim of the current study was to assess the impacts of tank color on the growth, stress, biochemical, hematological, and immunological responses, and expression of growth-related genes in juvenile Oscar (Astronotus ocellatus). Therefore, a total of 120 fish (9.14 ± 0.34 g) were distributed into 12 aquariums (60 × 50 × 35 cm) and divided into four treatments (aquariums with blue, white, yellow, and red colors) in three replicates (10 fish per aquarium). The fish were daily hand-fed ad libitum in three meals at 7:00, 12:00, and 17:00 hr for 56 days. Results showed that Oscar fish cultured in the red aquariums had higher final weight and weight gain and lower feed conversion ratio. Plasma cortisol, glucose, and lactate values of fish were significantly higher, and the amount of white blood cells was lower in the blue aquariums compared to other tank colors. Plasma triglyceride values were significantly higher in the white and yellow groups than the blue aquariums. Moreover, fish cultured in yellow and red aquariums had significantly higher melatonin levels than the blue aquariums. Plasma cholesterol, total protein, albumin, complement 3, and total immunoglobulin values were highest in Oscar fish cultured in the red aquariums. Also, lysozyme and alternative complement (ACH50) activities and complement 4 values of fish cultured in yellow and red aquariums were meaningfully higher compared to blue and white groups. Growth hormone relative gene expression levels were meaningfully higher in Oscar fish cultured in white, yellow, and red aquariums than the blue aquariums. Furthermore, insulin-like growth factor-1 (IGF-1) relative gene expression levels were significantly higher in fish cultured in yellow and red aquariums compared to those cultured in blue and white tank colors. Thus, the most suitable tank color for rearing juvenile A. ocellatus is red, while blue tank color is unsuitable.

Aquatic ecosystems are currently facing a multitude of stressors from anthropogenic impacts, including climate change, pollution, and overfishing. Public aquariums positively contribute to ecosystems through conservation, education, and scientific advancement; but may also negatively detract from these systems through collection of animals from the wild and sourcing from commercial suppliers. Changes within the industry have occurred, although evidence-based assessments of 1) how aquariums collect and maintain their populations to determine sustainability of the environment they have harvested; and 2) the welfare of these harvested animals once within the aquariums are still needed. The objectives of this study were to assess the ecosystem health of locations aquariums frequently visit to collect fish from the wild, and then evaluate the wellbeing of fishes at aquariums after extended periods in captivity. Assessments included use of chemical, physical, and biological indicators at field sites, and use of a quantitative welfare assessment at aquariums for comparison to species reared through aquaculture. Anthropogenic pressures at field sites were observed, but no evidence of high degradation or compromised health of animals were found. Welfare assessments of aquarium exhibit tanks produced high-positive scores overall (> 70/84), demonstrating that both wild collected (avg. score 78.8) and aquaculture fishes (avg. score 74.5) were coping appropriately within their environments. Although findings indicated that fish can be taken from the wild at low-moderate rates without any deleterious impact on the environment and cope equally well in aquarium settings, alternatives such as aquaculture should be considered as a strategy to reduce pressure on known stressed aquatic environments or where significant numbers of fishes are being taken.

AbstractModern-day zoos and aquariums market themselves as places of education and conservation. A recent study conducted by the American Zoo and Aquarium Association (AZA) (Falk et al., 2007) is being widely heralded as the first direct evidence that visits to zoos and aquariums produce long-term positive effects on people’s attitudes toward other animals. In this paper, we address whether this conclusion is warranted by analyzing the study’s methodological soundness. We conclude that Falk et al. (2007) contains at least six major threats to methodological validity that undermine the authors’ conclusions. There remains no compelling evidence for the claim that zoos and aquariums promote attitude change, education, or interest in conservation in visitors, although further investigation of this possibility using methodologically sophisticated designs is warranted.

Full textAbstract:
The extensive body of social science and humanities scholarship on zoos rarely discusses aquariums. Despite their independent historical trajectory and unique characteristics and challenges, aquariums are typically considered the younger sister to the more established terrestrial zoo institutions. This article is an initial exploration of modern public aquariums through the eyes of these institutions’ veterinarians, a small but rapidly growing, and quite influential, professional cohort. Drawing on in-depth interviews with a handful of aquarium veterinarians in various sites — including the United States, Canada, Israel, Portugal, Denmark, and Germany — the article documents some of the everyday challenges that these medical practitioners face when attempting to manage the health and wellbeing of captive marine animals. Their feet in several worlds, aquarium veterinarians must balance their medical training and animal welfare sensibilities with the specific nature of the aquatic animals under their care, and also with the understanding of their evolving responsibilities toward ocean conservation. For these professionals, the rights-welfare-conservation approaches to animal care are not abstract ideas but rather real-life situations that dictate their actual modes of practice in caring for marine animals. This can only be an initial study and thus highlights the need for additional scholarly work in the social sciences and humanities on aquariums, their wet forms of life, and the challenges— as well as the opportunities — that their management poses to the human caretakers of this space. This scholarly need is especially acute in light of the declining state of extant species and ecosystems in the world’s seas. Public aquariums and their veterinarians will arguably perform increasingly important roles in the conservation of our blue planet.

Aquarium care is a kind of a hobby. Aquariums are filled in with various fish species, invertebrates, plants, so aquarium water contains a huge amount of impurities, bacteria and microorganisms formed during the life of aquarium inhabitants. Currently, there appear the new aquarium filters for water purification with new consumer properties. There are considered the ways of treating water in aquariums by using different types of filters in order to study their functional qualities. Six internal filters of different brands and 1 external one were taken as the objects of study, their technical characteristics being presented. The time parameters of mechanical purification of aquarium water from the bacterial film by different filters were determined, the time limits of which correspond to 2-15 and 168 min. The operating time of the filters was calculated up to the point of deteriorating the quality of water filtration, which ranged within 5-12 min for all samples; one filter coped with the task of water purification in 60 minutes. The period of filter operation until the replacement or cleaning of filter materials has been stated. The minimal result is 168 hours, the maximal - 504 hours.

Marine life in aquarium are continuously producing harmful impurities and proteins which should be continuously removed is considered as a big problem in today’s aquariums. The water is equally important for living lives. The marine life requires equal attention for clean environment. The impurities in existing aquarium creates threat for the life of marine in result, fishes could not survive and could die as well, also for existing aquariums the removing impurities from water in the aquarium is a crucial issue. Frequent testing of water quality parameter such as Turbidity sensor to detect the suspended particles level in the water. This system will help the aquators to avoid the manual work and generate a balanced system where fishes can be survivable. This system is based on low cost electronic sensor level detection, an automated concentration measurement system is introduced to monitor the bad water quality that affect the health of fishes we propose an IOT based solution. This whole system is automated and give wireless control with the help of WIFI. The results are shown via webpage.

Full textAbstract:
Abstract As ocean’s apex predators, elasmobranchs are a very popular group in zoos and public aquariums. Since 30% of these species are threatened, there is a need within the zoo and public aquarium community to create a Regional Collection Plan (RCP) to coordinate the elasmobranch populations under human care. In 2011, Royal Burgers’ Zoo decided to change the Institutional Collection Plan (ICP) and stopped getting any sharks or rays directly from the wild. This study presents the potential and challenges of this approach. Although this study shows it to be a feasible approach for one public aquarium, implementing this ICP criterion in multiple public aquariums will require an increase in breeding efforts. There may also remain a need to collect animals from the wild as part of a conservation programme on threatened species or to increase the number of founders in a breeding programme.

Suboptimal nutrition may contribute to lionfish (Pterois volitans and Pterois miles) health issues in managed care environments. This study’s objective was to establish and compare whole blood fatty acid profiles in wild and aquarium lionfish. Whole blood samples were dried onto specialized high-quality paper cards from wild, invasive lionfish harvested off the North Carolina coast (n = 16) and lionfish managed by the North Carolina Aquariums (n = 12). Blood fatty acid profiles were analyzed from dried blood spots. Aquarium lionfish had significantly (p < 0.05) higher linoleic (18:2ω6) and eicosapentaenoic (20:5ω3) acid levels than wild lionfish. Similarly, aquarium lionfish had significantly (p < 0.05) lower saturated fatty acids and arachidonic (20:4ω6) to eicosapentaenoic acid (20:5ω3) ratios than wild lionfish. Total omega-3 and omega-6 fatty acids, as well as the ratio of these two fatty acid groups, were similar between wild and aquarium lionfish. Gut content analysis of wild lionfish diets included reef-dependent and schooling fish while aquarium lionfish diets were pelagic fish, crustaceans, mollusks, and commercial gel diets with nutrient supplements. This study reports whole blood fatty acid profiles in lionfish, providing comparative macronutrient data that may be useful for improving their nutrition and welfare in aquariums.

Full textAbstract:
L'eau des aquariums est source de Mycobactéries atypiques qui peuvent être pathogènes pour l'homme et les poissons. Une étude a été réalisée à l'aquarium du Musée de Zoologie de Nancy. La recherche de Mycobactéries a été effectuée dans 40 aquariums équipés de lampes germicides à UV : 11 bassins étaient alimentés en eau douce et 29 en eau de mer. Deux aquariums non équipés de système de désinfection ont également été analysés, les propriétaires de ces derniers ayant présenté un granulome cutané à M. marinum. L'action des UV sur M. marinum en suspension dans l'eau a été testée expérimentalement dans des bassins d'eau douce peuplés de Cichlidés. Pour chaque aquarium, un échantillon de 250 ml a été prélevé. Les cultures après décontamination au lauryl sulfate de soude ont été réalisées sur milieu de Loewenstein. Les résultats indiquent que, quel que soit l'aquarium, la présence de mycobactéries est constante. L'isolement des mycobactéries peut être gêné par la présence d'une flore bactérienne ou fongique importante (≥ 103 U.F.C./ml). Les espèces les plus fréquemment isolées sont M. gordonae et M. fortuitum ; M. kansasii et M. marinum ont rarement été isolées (6140 aquariums). Différents facteurs peuvent intervenir sur la sélection des espèces. La salinité de l'eau limite le développement de certaines espèces, alors qu'elle permet la croissance de M. fortuitum. Dans notre étude, la température de l'eau n'a pas été un facteur sélectif. L'utilisation de lampes UV limite le nombre de Mycobactéries. Dans les bassins expérimentaux, les radiations UV se sont révélées très actives sur M. marinum en présence ou en l'absence de poissons. A l'inverse de M. gordonae, M. fortuitum est rarement isolée en présence d'UV. Un nombre important de poissons par aquarium augmente la flore bactérienne et mycobactérienne. La prévention des infections à Mycobactéries atypiques chez l'homme comme chez les poissons devrait pouvoir être assurée par des mesures d'hygiène élémentaire.

Most of today's aquariums include aquatic conservation in their mission statement. Yet the conservation effectiveness of aquariums remains limited. The public possesses a minimal ecological understanding of aquatic biodiversity—of the variety of aquatic species and habitats. Most importantly, the public lacks concern about the health of aquatic systems. What can aquariums do? We must make conservation a key message in all aquarium programs. We must appeal to the public's fundamental values, revealing human dependence and impact upon aquatic life in a manner that emotionally connects them to the world under water. We must inspire long-lasting individual and collective behavioral change. We must expand our community presence; this presence enables us to bring together multiple stakeholders for consensus-building discussions of key aquatic issues, and to catalyze community participation in monitoring, habitat restoration, and clean up. We must create new partners for collaboration, including businesses, resource practitioners, and other respected community members. We must also expand policy involvement. Finally, we must actively apply new technologies in our exhibits and programs—technologies that help connect the visitor to the animals and to each other. Ultimately, we must create such a concern for aquatic biodiversity that people consider it priceless.

Cephalopods. On staged animals and popular science conventions at public aquariums.
Lars Kaijser
Keywords: Aquarium, cephalopod, popular science
The article discusses the way animals are portrayed in popular science, using cephalopods at public aquariums as the basis. Public aquariums tend to display a set of animals that could be described as flagship species. These are animals reoccurring as live examples in tanks, used in marketing and sold as toys in the gift shop.
Often, the presentations of these animals are enhanced with scientific facts that are combined with popular cultural stories and well-known iconographies. Together they form what could be labelled as popular science animals, easily recognisable animals with charismatic features. At aquariums, this generally refers to sharks, jellyfish, penguins, frogs or clownfish. The focus is on the biology of the animals, but equal importance is placed on the stories and popular-cultural association frameworks. The popular science animal is comprised of elements from different domains of knowledge, ranging from biology and cultural history to folklore and popular culture. These insights can be contradictory, and one important feature of presentations at aquariums is the endeavour to distinguish between fact and myth. At the same time, the myth is an important resource when curating exhibits and attracting attention. It is part of the convention that the selection of knowledge is not only chosen to inform people about animals but also to entertain and surprise them. The cephalopod is at the crossroad of research and imagination, viewed as enigmatic, fascinating, and fearful. It is characterised as smart, a superhero and a marker for both discoveries and knowledge gaps. The cephalopod, especially the octopus, is an animal that in many ways represents modernity.

Full textAbstract:
Cetaceans are long-lived, social species that are valued as ambassadors inspiring the public to engage in conservation action. Under professional care, they are critical partners with the scientific community to understanding the biology, behavior, physiology, health, and welfare requirements of this taxonomic group. The Cetacean Welfare Study was a highly collaborative research effort among zoos and aquariums accredited by the Alliance for Marine Mammal Parks and Aquariums and/or the Association of Zoos & Aquariums that provided important empirical and comparative information on the care and management of cetaceans. The goal was to identify factors that were related to the welfare of bottlenose dolphins and to develop reference intervals and values for common and novel indicators of health and welfare for common bottlenose dolphins (Tursiops truncatus), Indo-Pacific bottlenose dolphins (Tursiops aduncus), beluga whales (Delphinapterus leucas), and Pacific white-sided dolphins (Lagenorhynchus obliquidens). Data were collected from cetaceans at 43 accredited zoos and aquariums in seven countries in 2018 and 2019. This overview presents a summary of findings from the initial research articles that resulted from the study titled “Towards understanding the welfare of cetaceans in zoos and aquariums.” With multiple related objectives, animal-based metrics were used to advance frameworks of clinical care and target key conditions that were associated with good welfare of cetaceans in zoo and aquarium environments. As a result of this collaboration, species-specific reference intervals and values for blood variables and fecal hormone metabolites were developed and are freely available in an iOS application called ZooPhysioTrak. The results suggested that environmental enrichment programs and social management factors were more strongly related to behaviors likely indicative of positive welfare than habitat characteristics for common and Indo-Pacific bottlenose dolphins. These findings can be widely applied to optimize care and future science-based welfare practice.

Ammonia poisoning is a common problem in fish tanks but is not a disease and is one of the deadliest causes of aquarium fish mortality. This happens more in newly launched aquariums. Ammonia poisoning can occur immediately or within a few days. Initially, fish may be seen breathing on the surface of the water to breathe. The worst factor in ammonia poisoning is that excess ammonia is not visible in water, although its effects are visible.

AbstractA prototype telepresence communications system was designed, piloted, and tested for use in informal science education institutions to provide public, student, and educator interactions with scientists aboard ships and in the University of Rhode Island Graduate School of Oceanography (GSO) Inner Space Center (ISC). In addition to providing opportunities for the engagement of scientists with diverse audiences, a goal of this initiative was to promote an appreciation and understanding of the ocean, while exposing aquarium visitors to advanced telepresence communication technologies. The project partnership was comprised of a leading ocean science research and education institution (the GSO); two national ocean science education networks—the National Centers for Ocean Sciences Education Excellence Network and the National Oceanic and Atmospheric Administration's Office of Exploration and Research Education Alliance; and two partner aquariums—Mystic Aquarium and South Carolina Aquarium. The main outcomes of the project were as follows: (1) a partnership of ocean science research and informal science education professionals that linked ocean scientists and informal science institution staff and visitors; (2) a state-of-the-art hardware and software system for partner aquariums capable of delivering live and prerecorded ocean exploration experiences to visitors; (3) professional development for informal science educators focused on educating the public and improving ocean literacy; (4) a useful and effective digital media interface and software for communicating and interacting with the ocean science content; and (5) an understanding of how live and prerecorded ocean exploration experiences affect aquarium visitor ocean literacy.

To study people's perceptions and attitudes toward the importance of marine biodiversity, 102 visitors to San Francisco's UnderWater World aquarium were interviewed about their perceptions, attitudes, and knowledge about marine life and the environment needed for survival. They were asked about any changes in perceptions and attitudes after their visit. The data indicate that most visitors had very Little education in marine biology, that 84% had previously visited other aquariums, that 98% had maintained or increased their positive attitudes toward marine life, and that only 20% financially or emotionally supported marine animal protection or preservation societies. These data, especially from people who had previously visited aquariums, indicated a need for school and college classes and texts to include more substantial and interest-stimulating information about the encompassing importance of the oceans for the survival of all terrestrial and oceanic species.

Catfish farming is very profitable because the fish is easy to rear and can be harvested quickly. However, the cost of feed as the most significant component in production costs is currently getting higher. The availability and utilization of alternative feed is an urgent solution in creating sustainable catfish farming. This research was carried out during December 2020 – January 2021 in the Research Center for Limnology, Cibinong, Indonesia, which aims to determine the optimal proportion of minute duckweed (Lemna perpusilla) biomass added as feed supplemental to obtain an optimum growth of catfish fingerlings (Clarias sp.). Catfish were reared for 63 days in nine aquariums with a density of 25 fish per aquarium. The commercial pellet given in the control aquarium was 100% pellet portion (5% of the total fish weight), while in the treatment aquariums were 60% and 40% of the total fish weight. As compensation, fresh duckweed (L. perpusilla) was provided ad libitum. Fish were sampled twice to measure their weight and body length. This study showed that the proportion of duckweed as much as 40% as a supplement for commercial pellets could produce optimal catfish growth.

This research is an experimental study to know the effectiveness of the control system for pH, temperature, and turbidity of aquarium water in ornamental fish cultivation. The method used is by assembling an automation tool for controlling the pH, temperature, and turbidity of the aquarium water based on a microcontroller, which is then compared with an aquarium without a control system. This tool is designed using the Arduino Uno as a system controller, the pH sensor E-201-C as a measuring tool for pH levels with a solenoid valve to drain pH up and pH down as a stabilizer for water pH levels, the DS18B20 sensor as a temperature measurement tool by utilizing a heater and DC fan as a water temperature stabilizer, and the turbidity sensor as a turbidity measurement tool with a clean water replacement system as a water turbidity stabilizer. Based on the experiments carried out, it was found that there were significant differences between aquariums using a control system automation tool compared to aquariums without a control system tool. This means that the system that is made is effective and proven to be able to maintain the environmental conditions of ornamental fish with measurement results of pH ranging from 7–7.5, the temperature of 24°–27°C, and water turbidity of 10 NTU.

SUMMARY Recirculating water system (RAS), provide to reduce water usage and to improve the quality by nutrient recycling, so biofilters are used to reduce ammonia concentrations by oxidation to nitrate, by nitrifying-bacteria. Biological filters have been utilized to maintain acceptable water parameters to larvae and juveniles, by decreasing ammonia concentrations. The objective of this experiment was to evaluate different substrates for aquarium biofilter on performance of Nile tilapia (Oreochromis niloticus) larvae, and water quality. One-thousand-two-hundred Nile tilapia larvae (initial length = 11.6 ± 0.82 mm; body weight (BW) =189.0 ± 0.44mg) were randomly allotted into one of twenty 6-L aquariums (60 larvae aquarium-1) with five different biofilter (4 aquariums each biofilter): (1) control, no substrate; (2) seashell-and granitic crushed stone-substrate; (3) granitic crushed stone substrate; (4) quartz gravel substrate; and (5) porcelain-substrate. The conductivity, turbidity, pH, nitrate, nitrite and ammonia values indicate that seashell and granitic crushed-stone, and porcelain-substrates had greater process of biofiltration effectiveness. Water oxygen did not differ among treatments, with all levels within the benchmark for the tilapia larvae. Fishes reared in aquarium with quartz gravel-and porcelain substrate fishes had greater BW, total and standard length compared with its from other substrates. Porcelain-substrate biofilter is indicated for tilapia larviculture due to improved weight and length and water quality.

Public aquariums as part of the tourism industry are ted by the pandemic conditions which have caused a decline in visits. Concerns are also still looming over whether there will be another closure policy or a change in consumer behavior in the future. Therefore, Public Aquarium had to change its products and services to adapt to the new habits. This study aims to give recommendation design content on digital products developed as an alternative product form offered to consumers. The research began with a customer survey, followed by an analysis with two levels of QFD involving interviews and discussions. As a result, customers expect digital products that encourage learning about aquatic animals that develop interactive and engaging content. Public aquariums can design educational and entertainment content to convey their collection products into information and interactive technical functions that add value to consumer interest in the content provided.

There has not been a more dynamic period of growth in the aquarium industry than during the last two decades of the twentieth century. In 20 years, over 30 facilities were constructed in North America, Asia and Europe. A census of these facilities would show that over 50 million gallons of marine and freshwater exhibits were built to display a diverse collection of fishes, mammals, invertebrates and plants, many of which had never previously been exhibited. At the outset of this generation of aquarium building, there was limited information as to what engineering and water treatment technology might be suitable or available for the maintenance of healthy aquatic environments. In fact, such an engineering specialty did not possess a name or professional designation. The punctuated building of aquariums spurred the creation of a new breed of design specialist, the aquatic life support engineer. Initially the mechanical engineers and biologists that were in the vanguard of this new specialty had limited water quality data to develop their designs. Aquarium biologist began collecting the data and eventually forged a collaborative design relationship with engineers eager to develop new approaches for aquatic life support. Consequently, as aquariums enter the new millennium, the fundamental principles of life support design have never been more clearly defined. Simply put, the basic platform of life support design is water filtration, and the three technological pillars that support that platform are biological, chemical and mechanical.

Full textAbstract:
The effects of two aquatic plants, duckweed (Lemna sp.) and azolla (Azolla sp.), on the growth performance of fantail goldfish (Carassius auratus) and dissolved nutrient concentrations were studied. The experiments were carried out in triplicate sets over a period of seven weeks. Eight specimens of fantail goldfish (length = 5.16 ± 0.06 cm; body weight = 2.30 ± 0.06 g) were released into each of the aquariums containing 40 L of water. Submerged sponge filters were used as the substrate (bed) for the nitrifying bacteria to facilitate nitrification. The fish were provided feed at the rate of 2% of their body weight twice daily. In situ and ex situ water parameters (temperature, dissolved oxygen, pH, total suspended solids, ammonia, nitrite, nitrate, and phosphate), body weight and length of the Fantail goldfish, and wet weight of aquatic plants were measured weekly. The results showed no significant differences (p > 0.05) in any of the three aquariums in water temperature, pH, and dissolved oxygen. Survival of the fish was 100%. The highest food conversion ratio and specific growth rate were observed in the aquarium stocked with duckweed, followed by the aquarium with azolla and the control set (p < 0.05). The concentrations of nutrients (ammonia and nitrate) were recorded lowest (p < 0.05) in the aquarium with azolla, followed by duckweed and the control. The results suggested that aquatic plants were effective in absorbing nutrients and can serve as biofilters to create better conditions for the growth of the fantail goldfish.

Abstract Background Nearly all U.S. cases of melioidosis, a potentially fatal disease caused by Burkholderia pseudomallei, are associated with travel to endemic areas. In September 2019, a patient in Maryland with no international travel history developed melioidosis and whole genome sequencing (WGS) of the patient’s clinical isolate showed it clustered most closely with isolates from Southeast Asia. CDC and Maryland Department of Health (MDH) investigated possible sources of B. pseudomallei exposure to identify the source and route of transmission and evaluate risk to others. Methods MDH interviewed the patient and household members during October–December 2019. In consultation with CDC, MDH conducted environmental sampling of the patient’s home including drains, faucets, potted and ground soil, imported products, and two freshwater aquariums. Samples were tested for B. pseudomallei at CDC by PCR and culture. B. pseudomallei isolates underwent WGS and were analyzed along with a reference panel of geographically diverse, publicly available genomes. Results Three environmental samples, all from aquarium #2, were positive for B. pseudomallei. These isolates matched the patient’s clinical isolate by WGS, suggesting the aquarium was the source of exposure. According to interviews, the patient set up both aquariums in July 2019 and all the fish in aquarium #2 died in August 2019. The patient recalled reaching her bare hands and arms into the aquarium in August 2019, one month prior to illness onset. Conclusion This investigation led to the first documentation of transmission of B. pseudomallei from a freshwater aquarium to a human. Many freshwater ornamental fish are imported from Southeast Asia, so this newly recognized transmission route may have significant implications for the freshwater aquatics trade. Further investigations are underway at the retail location that sold the fish and the commercial vendors that supplied the freshwater animals and plants imported from Southeast Asia.

Full textAbstract:
Consumer demand for invertebrates is on the rise as their numbers in the wild dwindle. However, with the growing conservation efforts of modern zoos and aquariums, and evidence from over 300 studies showing that invertebrates are capable of sentience, public interest, and moral concern for welfare of invertebrates have increased. The challenge for zoos and aquariums is in developing an objective and repeatable method for evaluating welfare that can be applied to invertebrates in zoological collections. Recently introduced into zoological collection management is the Animal Welfare Assessment Grid (AWAG). The AWAG helps to identify negative and positive welfare states, through assessing animal- and environmental-based indicators to make changes that lead to a better quality of life. Originally developed for the assessment of laboratory primates, the system has been successfully adapted to assess a variety of taxa across different environments, facilitated by the development of cloud-based software. In this study, the AWAG has been adapted to assess the cumulative lifetime experience of captive decapods and cephalopods at two different institutions, Marwell Zoo and National Marine Aquarium. This study has provided further evidence that the AWAG is adaptable and demonstrates the first time any objective scoring system has been successfully adapted for use in invertebrates. Through graphical representation, the results show that the AWAG identifies changes in welfare scores that can be attributed to specific events and can be used to predict the future vulnerability of species to welfare changes and suggest alternative management methods. This monitoring tool provides a versatile method of implementing practical welfare monitoring in zoos and aquariums.

The aim of the present study was the investigation of the biological cycle of the isopod parasite Ceratothoa oestroides (Risso, 1836), the way of installation in the host and the study of its pathology in young individuals of gilthead sea bream {Sparus aurata) and sea bass {Dicentrarchus labrax) raised in experimental aquariums. During the experiment, initially, 10 sea bass of marketable size (300-400gr) were collected infected with lice from the region of Chios and Epidavros. The lice were mature and gravid. The adults and their hosts were kept in 151t aquariums, with constant water of 32-33%c salinity at temperature of 21-22° C, until they would give both to young parasites. The time that parasites stayed in aquarium was three months. After three months, new hatched larvae appeared. The pulii II stage, which was responsible for the most alterations that were observed in the fish and particular in sea bass, were observed in the first week, after the hatching. In this stage, parasites swam freely in the surface of water column. At this phase, 100 parasites were transported in 2 different aquariums with the same conditions of salinity and temperature as in the first aquarium, where young uninfected individuals (3-5 gr) of gilthead sea bream {Sparus aurata) and sea bass {Dicentrarchus labrax) were placed. The number of the uninfected, healthy fish was 40 individuals per aquarium. During the duration of experiment four weekly samplings of five individuals per sample were performed and these underwent a macroscopical, parasitological and histopathological examination. In addition, the mortalities that existed and the final luck of parasites afterwards the death of their hosts were recorded. From the results, we concluded that pulii II stage caused serious lesions and eventually the death of mainly young fish, gilthead sea bream {Sparus aurata) and sea bass {Dicentrarchus labrax). The process from the moment of "invasion" of young parasites until their final installation in the buccal cavity lasted around 2 hours. In one week, all the isopods were installed in the buccal cavity of young gilthead sea bream {Sparus aurata) and sea bass {Dicentrarchus labrax). During the second week, the first symptoms of fish appeared. The infected fish swam fast and rubbed their body against the aquarium surface in order to remove the parasites. In the sea bass {Dicentrarchus labrax), with the appearance of first symptoms, the biggest rate of mortality (56,25%) followed, while in the gilthead sea bream {Sparus aurata), the biggest rate of mortality (52%) was observed in the third week. With regard to the luck of the young parasites that remained without host it was observed that they swam for 48 hours, then fell in the bottom of aquarium and after 24 hours the first mortalities started. The adult parasites, that gave the young pulii II after 24 hours, were dead in the bottom of aquarium.

Modern zoos and aquariums aspire to contribute significantly to biodiversity conservation and research. For example, conservation research is a key accreditation criterion of the Association of Zoos and Aquariums (AZA). However, no studies to date have quantified this contribution. We assessed the research productivity of 228 AZA members using scientific publications indexed in the ISI Web of Science (WoS) database between 1993 and 2013 (inclusive). AZA members published 5175 peer-reviewed manuscripts over this period, with publication output increasing over time. Most publications were in the zoology and veterinary science subject areas, and articles classified as “biodiversity conservation” by WoS averaged 7% of total publications annually. From regression analyses, AZA organizations with larger financial assets generally published more, but research-affiliated mission statements were also associated with increased publication output. A strong publication record indicates expertise and expands scientific knowledge, enhancing organizational credibility. Institutions aspiring for higher research productivity likely require a dedicated research focus and adequate institutional support through research funding and staffing. We recommend future work build on our results by exploring links between zoo and aquarium research productivity and conservation outcomes or uptake.

A six months trial was conducted to evaluate the dietary effect of Safed Musli root powder on Jayanti Rohu post larvae. The substantial losses of fish during the post-larval phase have been one of the bottlenecks in the Indian major carp (Labeo rohita). The Safed Musli different dietary levels like 0 g/kg in control diet (C), 0.25 g/kg in treatment Cb1 diet, 0.50 g/kg in treatment Cb2 diet, and 0.75 g/kg in treatment Cb3 diet. The Jayanti rohu brood stocks were fed with test diets @ 3% of body weight during experimental period. After six months feeding, Jayanti rohu brooders were performed breeding in different-different spawning pools. Then eight days old post larvae of Jayanti rohu were transferred into the 12 nursery ponds and 12 aquariums at the rate of 10 million spawn per hectare. Jayanti rohu spawn for feeding mixture of finely powdered groundnut oil cake and rice polish, in equal proportion by weight was supplied in both system nursery and aquarium. Starting on the day of stocking, feed can be broadcast all over the pond and, aquariums. The length weight was measured at initial and final time of experiment. The survival rate was measured at the final time of experiment. The maximum weight (3.63b±0.005) and length (6.49d±0.034) was found in treatment Cb2 in nursery pond system in compare to aquarium tanks. The maximum survival rate also found in treatment Cb2 (41.11d±0.12) in nursery ponds. Both systems showed significant relationships between treatment and control groups (p<0.05).

Full textAbstract:
Dwarf water hyssop (Bacopa monnieri) is a popular choice among aquarium enthusiasts for its ease of care and rapid growth. Despite its popularity, research on its suitability as an aquarium plant is scarce. The objective of this study was to assess the effects of various fertilizer formulas and growth performance in both emerged and submerged culture systems. Dwarf water hyssop was cultured for four weeks in emerged and submerged systems using different NPK fertilizer formulas (18-18-18, 25-5-5, 30-20-10, and 8-24-24), alongside a control group without fertilizer. Remarkably, growth performance (i.e. plant height, number of leaves, number of nodes, and root length) and survival rate did not significantly differ between plants with and without fertilizer application in either culture system. Among the fertilizers tested, treatment 4 (NPK 30-20-10) showed the most promising results for dwarf water hyssop growth in both emerged and submerged culture systems. In the emerged system, these treatments led to a minimum height increase (7.96±1.49 cm), a medium number of new leaves (4.41±1.91 leaves/explant), a moderate number of new nodes (3.08±0.29 nodes/explant), and a substantial root system length (2.67±1.16 cm). Conversely, in the submerged system, a minimum height increase (1.65±0.32 cm), medium number of new leaves (1.33±1.66 leaves/explant), moderate number of new nodes (1.08±0.76 nodes/explant), and root system length (0.36±0.86 cm) were observed. Overall, plant morphology and growth performance were superior in the emerged system compared to the submerged system after four weeks of culture. Outstandingly, all plants survived, regardless of fertilizer application of formula, in both culture systems. Given its slow growth, dwarf water hyssop is ideal for aquarists seeking a dwarf aquatic decoration. The emerged culture system is recommended for mass production of this ornamental plant, while the submerged culture system is suitable for elaborate ornamental aquariums.

This paper presents an automatic water exchange system designed for a freshwater aquarium. The automatic water exchange system (AWES) was developed to improve the aquarist’s work. Replacement of water in an aquarium is one of the basic maintenance activities and should be performed regularly. In case the process of pouring in and out of the water itself requires a lot of time and strength from the aquarist, the automation of this operation is proposed. The automatic water exchange system consists of a water discharge system, a water filling system, and a security system. Additionally, to simplify user operation, a dedicated mobile application for the Android system has been created. The developed AWES system allows for regular changing of water in aquariums as well as enables effective and simple control of water flow and temperature.

In fish farming, there is a lot of time in feeding irregularly or many farmers who have many fish aquariums but have difficulty in feeding because of the inefficiency of very little time and resulting in many fish causing stress and some fish that die. This research presents an innovation that changes the way to care for fish in an aquarium. Using Internet of Things (IoT) technology and Arduino Uno, this automatic fish feeding system was created with a focus on energy efficiency and fish welfare. With an internet connection, farmers can control and monitor the feeders through an app. The system also optimizes the use of electrical energy and monitors the environmental conditions of the aquarium in real time. This research offers a stunning innovation, combining technology and sustainability to better care for fish.

Aquariums and "blue water" oceanographic institutions in America have traditionally had completely separate missions, with the former concentrating on public outreach and education and the latter undertaking basic research. Recently, two new institutions, the Monterey Bay Aquarium Research Institute (MBARI) and the Mystic Aquarium/Institute for Exploration (MA/IFE), were founded for the expressed purpose of bridging the gap between basic ocean discovery and public education. In both cases, the ability to bring the excitement of undersea exploration to the public has been enabled by sophisticated undersea vehicles that permit the aquarium audience to participate in the research enterprise via telepresence. The fact that the research is constantly in the public eye provides researchers with frequent opportunities to explain the importance and the relevancy of their work for the benefit of society. Despite the efforts over the past 50 years, over 95 percent of the oceans remain unknown and unexplored. This fact combined with the realization that all citizens of the twenty-first century must be well informed on the consequences of their actions on the health of this ocean planet makes it likely that such partnerships between research and educational institutions will proliferate.

With the shift in their social roles, modern zoos and aquariums are required to develop scientific research. Although zoos and aquariums worldwide have reported an increase in the number of papers they publish and the diversification of their fields in recent decades, the specific circumstances in Japan are slightly unclear. We listed peer-reviewed papers authored by Japanese zoos and aquariums using search engines and quantitatively evaluated the changes in the number of papers published over 62 years. Our results showed that papers published in Japan have increased remarkably since the 1990s, and research fields have diversified as in the rest of the world. In particular, joint research with research institutes has seen an upward trend, and the instances of English-language papers have increased. Meanwhile, the content of the research was biased. In zoos, research on animal welfare has been increasing, but the focus was heavily biased toward captive mammals. Aquariums contributed to the understanding of local ecosystems through the fundamental study of wildlife, but there were fewer papers on improving husbandry. Our results indicated that while research by Japanese zoos and aquariums is developing, research on welfare, conservation, and education regarding native endangered species must still be improved.

Nile tilapia (Oreochromis niloticus) has always been considered more resistant to diseases compared to other fish species. However, in recent decades, this fish species has also been susceptible to many bacterial, fungal, parasitic, and nutritional diseases. In Brazil, streptococcosis is one of the main diseases that affect tilapia and has caused many economic losses. A resistance test was conducted with 93 tilapia of four varieties (UFLA strain and three commercial varieties: SC1, SC2, and SC3) to evaluate resistance to experimental inoculation with Streptococcus agalactiae. Each variety was distributed in five aquariums, with nine specimens of the same variety. Among the five aquariums, four housed fish were intraperitoneally inoculated with 107 CFU/fish of S. agalactiae and one aquarium harbored fish from the control group, which received 0.1 mL of sterile BHI (Brain Heart Infusion). Significant differences were observed in the survival rates accumulated at the end of the experiment (day 15), with values of 22, 36, 36, and 15% for SC1, SC2, SC3, and UFLA, respectively. The UFLA strain presented lower survival than other strains, which did not differ among the 15 days of challenge. These results demonstrate that there are animals with a better response to the resistance test than others.

In recent years, pathogenic forms of Candida albicans have been activated and isolated in aquariums of commercially valuable fish and in closed water systems (CWIs). They largely colonise the digestive tube and lead to the death of 95‑100% of fish. Treatment methods for aquarium fish bred for food purposes are ecologically and economically unjustified, as the preparations retain a certain toxicity. In this regard, it is necessary to search for environmentally friendly methods of prevention and therapy of candidaemiasis in aquariums and CWIs. It was found that propolis in complex with methylene blue promotes complete elimination of toxicity and suppressive action of sensitizers, inhibition of increased reproduction of Candida in the organism of Oreochromis niloticus, strengthening of haematopoiesis processes, increase of neutrophils, monocytes and activation of phagocytosis. In comparison with the data of the infected fish of group 2, the level of neutrophils increased by 1.63, 1.6, 1.82 and 1.67 times, monocytes by 1.94, 2.58, 3.08 and 3.1 times on the 7th, 14th, 21st and 30th day of the experiment. This contributed to the restoration of the functional activity of cells and phagocytic reactions in the organism of O. niloticus, increasing the ecological environment, productivity and quality of the obtained dietary protein, meat rich in essential fatty acids omega‑3 and -6.

Full textAbstract:
To live up to their goals of education and conservation, as well as to richen the visitor experience, aquariums in the 21st century must become more effective at promoting informal, inquiry-based learning within and surrounding their exhibits. We examine a number of ways of using the technology of networking to further those goals. The methods discussed fall into six broad categories of use: orientation, delivering information on demand, tailoring the experience to the individual, viewing and observing the simulated aquarium habitat, connecting simulated habitats to their wild counterparts, and extending the experience beyond the aquarium visit. Within this context, we also examine the role of graphical and robotic simulations in the aquarium. The networked aquarium concept, applied within the context of a rich variety of live exhibits and activities, has the potential to enhance visitors' primary experiences in the aquarium by making connections among successive exhibit experiences, and supporting connections between the aquarium experience and visitors' further life experiences. By enhancing such linkages, a network should foster its users' ability to build fundamental ideas in and around the aquarium setting and more easily apply them in other circumstances; the hallmark of real learning. It further allows the aquarium to attract and serve its visitors more effectively.

Full textAbstract:
High-resolution non-invasive cetacean tagging systems can be used to investigate the influence of habitat characteristics and management factors on behavior by quantifying activity levels and distance traveled by bottlenose dolphins (Tursiops truncatus and Tursiops aduncus) in accredited zoos and aquariums. Movement Tags (MTags), a bio-logging device, were used to record a suite of kinematic and environmental information outside of formal training sessions as part of a larger study titled “Towards understanding the welfare of cetaceans in zoos and aquariums” (colloquially called the Cetacean Welfare Study). The purpose of the present study was to explore if and how habitat characteristics, environmental enrichment programs, and training programs were related to the distance traveled and energy expenditure of dolphins in accredited zoos and aquariums. Bottlenose dolphins in accredited zoos and aquariums wore MTags one day per week for two five-week data collection periods. Overall dynamic body acceleration (ODBA), a proxy for energy expenditure, and average distance traveled per hour (ADT) of 60 dolphins in 31 habitats were examined in relation to demographic, habitat, and management factors. Participating facilities were accredited by the Alliance for Marine Mammal Parks and/or Aquariums and the Association of Zoos & Aquariums. Two factors were found to be related to ADT while six factors were associated with ODBA. The results showed that enrichment programs were strongly related to both ODBA and ADT. Scheduling predictable training session times was also positively associated with ADT. The findings suggested that habitat characteristics had a relatively weak association with ODBA and were not related to ADT. In combination, the results suggested that management practices were more strongly related to activity levels than habitat characteristics.

Full textAbstract:
Abstract The aim of this study was to evaluate the effect of different colors in development and survival of catfish Lophiosilurus alexandri larvae, as well as over the visual ability of the handler. Larvae were placed in 5 L-aquariums at a density of 7 larvae L-1 , and aquariums had different colors, and were: green and blue (light colors); brown and black (dark colors). The final development; survival, total and standard length, weight and biomass of the larvae were similar in all colored aquaria. The highest mortality occurred during the first days after hatching, declining over the period, when it is observed the larval development, indicating that care should be necessary in the first few days. During cleaning handling, the accidental catch of larvae was higher in black aquariums. In the first days of life, due to the fragility of the larvae, it is possible to verify that between the second and third day occur the greatest mortalities. The number of accidentally captured larvae was lower than the mortality, suggesting that the high mortality in early larval life is not influenced by the handler management. The catfish L. alexandri larvae should be cultivated in aquariums that allow a good contrast between the larvae and the background, to avoid accidental capture of larvae by the handler. It is suggested to avoid the use of dark and black aquariums.

Full textAbstract:
It is now well established that human-induced species extinctions and habitat degradation are currently occurring at unprecedented rates. To halt and reverse this decline, the international community adopted the Kunming–Montreal Global Biodiversity Framework (GBF), as part of the Kunming–Montreal Biodiversity Package, in December 2022. We clarify what this new framework means for conservation zoos and aquariums in their mission to prevent species extinction by highlighting areas of focus. We explain why it is necessary that conservation zoos and aquariums establish the appropriate mechanisms for contributing towards such a framework to help validate their role in the 21st Century. Conservation zoos and aquariums should be reassured that much of their work already fits within the GBF. However, the current mechanisms for individual zoos and aquariums to directly contribute to the implementation of the GBF mostly rely on close collaboration with individual national governments and/or are only possible at a national level. It is therefore critical that national, regional, and global zoo membership organisations take a leading role in championing the work of their members. Equally, adequately linking the efforts of zoos and aquariums to the national implementation of international instruments, such as the GBF, is imperative to ensure that these organizations’ contributions feed into the understanding we have of global progress towards the implementation of international instruments.

Full textAbstract:
Purpose – To establish tourist visitation to new tourism areas is in most cases dependent on tourists' behavior. Indeed, tourist visitation is considered among the primary components of the marine tourism operation. Such behavior is usually enacted in the form of destination awareness, destination image and motivation. Word of mouth is likely to influence tourist to visit. The purpose of this paper is to examine the factors that may influence tourists to visit marine tourist destinations. Design/methodology/approach – The study has utilized self-administered questionnaire survey and the target population are the visitors that came to FRI Aquarium. The survey period was from August 2012 to September 2012. Total of 179 responses were collected during this period. Findings – This study demonstrates that destination awareness, motivation and WOM are factors that influence the tourist to visit the FRI Aquarium. Interestingly, destination image however, has shown insignificant relationship with tourist visitation. WOM also found to be has a full mediating effect for awareness towards tourist visitation. For example, before visit, visitor may require some information beforehand and word of mouth is a direct medium to transfer the information. A key implication for FRI Aquarium is that it might be wise to assess such variables for their marketing strategies. Research limitations/implications – First, the sample was obtained from one marine aquarium in Malaysia. The comparative studies between aquariums are important to understand if there are any similarities and differences. It would be better to conduct the survey in other local aquariums such as the Underwater World, Langkawi and the KL Aquaria, Kuala Lumpur. Second, a longitudinal study is relevant to further investigate the factors that will influence the visitor visitation. Thus, future study should gather data from those who had visited the aquarium several times. This approach might improve the destination image results, which in this study shows insignificant relationship. That said, acknowledgements of these limitations also suggest a new direction of future research. Practical implications – FRI Aquarium is suggested to create more awareness to the public by placing an advertisement via mainstream and social media. Hence, FRI Aquarium is suggested to design environmentally marine life oriented educational programs in order to motivate and encourage more visitors to visit the place. Originality/value – In sum, this paper conjectures that an understanding of factors that influence the tourist to visit the marine tourism destination are worthy of additional research. Consequently, the findings help to understand how these factors can provide alternative sources of marketing to attract the long-term economic sustainability of the FRI Aquarium in marine tourism.
