Aquaculture is a growing industry in Florida, and there is particular interest in offshore marine aquaculture. While inland and coastal aquaculture (like for shellfish or ornamental fish) is managed by the Florida state agency Florida Department of Agriculture and Consumer Services (FDACS), offshore aquaculture also involves federal management agencies. However, there has been some confusion and disagreement about which federal agencies will manage and make decisions about offshore aquaculture in the United States. This document describes a recent history and current state of that discussion. This information is important for potential aquaculturists and other stakeholders to understand, and should also provide guidance to management and outreach agencies seeking to inform stakeholders about offshore aquaculture.

In Chile many experiments to artificially produce juvenile Cryphiops caementarius have been carried out in order to obtain enough stock for aquaculture or repopulation in natural habitats. The aquaculture production technology has been developed by the research staff of the Aquaculture Department of the Universidad Católica del Norte, with the aim of enhancing cultivation at commercial level, obtaining a sustainable production, and decreasing the fisheries pressure on natural populations. The latter is now based on the collection of ovigerous female obtained from their natural habitat. The research shows that it is possible to cultivate C. caementarius juveniles in 65 days through 18 zoeal stages.

Full textAbstract:
Russia, like no other country in the world, has a huge potential for fish-farming development. According to data of different authors, in Russia from 12 to 16 million hectares of water areas of inland water bodies are suitable for fish-farming. Aquaculture farms potential in Russia is estimated at, at least, 2-3 million tons. It should be borne in mind, however, that our statistics do not take into account the so-called micro water bodies with an area of less than 1 hectare. The Department of Economics and Accounting in Agroindustrial Complex of the Irkutsk State Agrarian University in collaboration with Ministry of Agriculture of the Irkutsk Region carried out a study of aquaculture production state, identified factors that hampered its development, gave recommendations on use of forms of state support for agricultural aquaculture producers. The article is devoted to the current state and problems of commercial fish-farming development in Russia, including main aquaculture objects cultivated in Russia and its potential species; volume of catching aquatic biological resources and production of aquaculture products in Russia from 2007 to 2016 and main directions of state support for this sector.

Full textAbstract:
Abstract Objectives Americans consistently fail to meet dietary guidelines for seafood intake. Efforts are needed to increase consumption, especially of sustainable seafood that can be supplied by domestic aquaculture. However, consumer receptivity to aquaculture products is mixed. The objective of this study was to elicit industry perspectives regarding influences on consumer purchases of aquaculture products. Methods Key informant interviews (n = 12) were conducted in late 2020 with U.S. salmon, shrimp, and oyster producers, marketers, and industry interest groups. Participants were recruited via snowball sampling. Virtual interviews were conducted by a trained moderator and assistant moderator/notetaker using a semi-structured interview guide. Qualitative data analysis included a thematic review of interview recordings and notes, with key concepts coded according to a priori themes derived from the literature. Results Interviews yielded important insights into consumer receptivity to aquaculture products. Participants believe that outdated misperceptions of aquaculture persist, noting that despite advances in domestic aquaculture production practices to comply with U.S. standards, some consumers perceive aquaculture as environmentally detrimental and unsustainable. Further, participants believe negative attitudes toward genetically modified organisms, corn and soy-based feeds, antibiotics, and chemicals are misplaced, yet contribute to hesitancy among some consumers. Industry opinions on what is important to consumers reflect strong valuation of seafood quality, freshness, local harvest, and sustainability. Participants suggest product labeling efforts be developed accordingly, and that innovative marketing strategies be undertaken, such as aquaculture product promotion through “know your farmer” campaigns, chef education initiatives, and home delivery programs. Conclusions For domestic aquaculture products to have a meaningful impact on U.S. seafood intake, positive consumer receptivity is key. Industry perspectives will inform marketing and educational efforts toward addressing consumer hesitancy to purchase aquaculture products by resolving misguided concerns, with important implications for consumer health and sustainability of the domestic seafood supply.

Full textAbstract:
Aquaculture is the fastest growing segment of the global food production sector, valued at $70.3 billion in 2004. In recent years, global capture fisheries have leveled off at around 95 mmt per year, with little or no prospect of increasing yields. The United Nations Food and Agricultural Organization (UNFAO) has concluded that increases in future seafood supplies must come from aquatic farming. The United States (U.S.) industry has been among the fastest growing agriculture sectors. Domestic seafood from capture and culture fisheries provides about 20% of annual consumption, the balance coming from imports. Future supply will come from either increasing imports or, preferably, expanding domestic aquaculture and fisheries sources. The greatest opportunity for domestic growth is marine aquaculture, particularly placement of large and small farms in the U.S. Exclusive Economic Zone (EEZ). Additional benefits can accrue if large-scale marine hatchery technology is developed, so that fingerlings can be produced for wild stock enhancement and management. Currently, there is no permitting and leasing regime for ocean farming in the U.S. EEZ. In response to several national commissions, the National Oceanic and Atmospheric Administration (NOAA), U.S. Department of Commerce (USDOC) is spearheading a bold effort to implement long-term marine aquaculture development objectives and create an EEZ permitting and leasing mechanism. Enabling legislation, entitled the National Offshore Aquaculture Act of 2007, is before Congress. Anchoring fish farms in the relatively shallow near shore and the EEZ is an exciting prospect for greater U.S. seafood self-sufficiency. However, there are many institutional, environmental and technical issues to resolve. More compelling is the prospect of developing new marine aquaculture technologies, e.g., single-point moorings, untethered cages, and integrated multi-trophic systems, to sustainably utilize the deep ocean beyond the EEZ. Successfully tackling this looming challenge will need the diverse expertise of the U.S. marine technology industry.

Ponds are considered to be self-contained, land lock ecosystem which is often teeming with rich vegetation and diverse organismal life. The pond water contains different organic and inorganic components. The experiment was carried out in laboratory, Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh through collection of pond water from Gouripur and Muktagacha under Mymensingh division for assessment of major ionic status and suitability parameters for irrigation and aquaculture usage in quantitative way. Around 30 samples were collected from different location. On the basis of HCO3 ion, all water samples except 3 samples were not suitable for irrigation because this anion exceeded the acceptable limit (1.5 meL-1). On the other hand, HCO3 ion was not treated as problematic in all samples except 2 samples for aquaculture usages. The concentrations of Ca, Mg, Na, K, PO4 and SO4 were far below the recommended limit. Considering aquaculture usage, Cl ion was considered as hazardous in all the pond water samples because this anion was above the legal limit (<0.003mgL-1). pH value of pond ranged from 7.02 to 7.87 indicating alkaline in nature and were not problematic for irrigation and aquaculture usage. Among the major ionic constituents, the remarkable significant correlations existed between Ca vs Mg, Ca vs K, Mg vs SO4, K vs Na, Na vs SO4.

In the Food, Conservation, and Energy Act (Farm Bill) of 2008, Congress amended the Federal Meat Inspection Act to provide that catfish be inspected by the U.S. Department of Agriculture's Food Safety and Inspection Service (FSIS). As part of the development of its inspection program, the FSIS conducted an assessment of the food safety risk associated with consuming farm-raised catfish. To thoroughly identify hazards for consideration in the risk assessment, the scientific literature was surveyed for all potential agents that have been linked to illness associated with farm-raised catfish consumption. A review of microbial hazards suggested that Salmonella is the foodborne pathogen most likely to be associated with catfish, but the impact of other pathogens remains unclear. This review also summarizes the current data available on chemical residues in catfish, including pesticides and heavy metals, and any regulatory levels that have been established for these compounds. The current usage of veterinary drugs in aquaculture also is outlined, including information on unapproved usage of drugs in catfish.

The present experiment was designed to simulate an on-going field trial at Au Tau Substation, Agriculture and Fisheries Department, Hong Kong Government, using a series of fishponds to treat polluted riverwater, as well as for promoting algal growth, before the water was used for rearing freshwater fish. It was revealed that aeration was necessary to lower the level of ammonia. It also accelerated the conversion of ammonia to nitrite, and then nitrite to nitrate. Substantial amounts of metal (K, Mg, Cu, Zn) were also removed from the riverwater, possibly by algal assimilation. The algal products contained a high crude protein content (42% dry weight basis) which could be used to feed carp and tilapia.

Understanding the information-seeking behavior of library patrons is essential for the library to provide quality resources and services, and to satisfy its patrons’ information needs. A quantitative research was conducted to describe the information searching and using behaviors of the Filipino aquaculture scientists, researchers and research staff at the Aquaculture Department of the Southeast Asian Fisheries Development Center (SEAFDEC/AQD). The study revealed that although the respondents find it useful to go to the library to get assistance from the librarian, and to browse and read current acquisitions related to their research, they visited the library infrequently. However, remote library services, especially email and phone services, were highly utilized. When searching for information, the Internet, mainly via search engines, was highly preferred rather than visiting the Library and using its online public access catalog (OPAC) or its databases. The combination of print and electronic formats was highly preferred when reading, rather than print only or electronic-only. The majority would print and save the retrieved electronic copy.

Purpose – This paper aims to present the experiences of SEAFDEC/AQD library staff in digitizing institutional publications and developing an institutional repository (IR). Design/methodology/approach – SEAFDEC/AQD IR or SAIR provides a reliable means for its researchers to store, preserve, share their research outputs, enable easy access to and increase the visibility of its scientific publications. The repository uses DSpace customized with some add-ons. Details on the digitization hardware and software, layout, delivery format, and persistent identifier used are provided. Findings – As of March 2012, the repository contains 771 items with 541 downloadable PDFs. SAIR had 88,287 item views, 69,249 PDF downloads and 271,978 searches. SAIR is registered to and indexed by OpenDOAR, ROAR, Google Scholar and WorldCat. It is harvested by AVANO Ifremer, BASE, Sciencegate.ch and OAIster. Initial impact based on indicators in webometrics ranking web of world repositories and research centers was presented. Reluctance to contribute to IR has been observed by the library staff among SEAFDEC/AQD researchers. Research limitations/implications – The IR can be an effective tool to promote institutional publications and those written by researchers in peer-reviewed journals and to generate higher citations through increased visibility. IR submission policy and procedures are being drafted by the library staff. Practical implications – SAIR provides free access to all in-house publications of SEAFDEC/AQD. Full-text digitized copies of fish farmer-friendly materials like books, handbooks, policy guidebooks, extension manuals, institutional reports, and newsletters can be downloaded. Originality/value – SAIR is one of only three open access institutional repositories registered in the Philippines. The paper discusses the lessons learned and issues to be addressed in developing an IR of value to other institutions considering similar projects. Future plans and further development are also presented.

The Kenyan Economic Stimulus Program was developed with an objective to spur regional development. The program targeted the establishment of 200 fish ponds in the selected constituencies in Kenya. Farmers were trained on production management skills and capacity building by the department of fisheries and other institutions sharing similar objectives. In spite of this intervention, there has been a declining trend in the production of fish in Kisumu West Constituency. This study therefore sought to establish if a significant relationship existed between the decline in the performance of aquaculture farms and acquisition of production management skills. The main objective of the study was to establish the effect of farmer production management skills on production levels of the Economic Stimulus Program financed aquaculture farming projects in Kisumu West Constituency, Kisumu County, Kenya. A total of 389 farmers were interviewed. The population of 417 farmers consisted of farmers with different forms of financing including economic stimulus, personal, and Sacco/group loans. A descriptive survey design was employed to collect both quantitative and qualitative data to achieve the objective of the study. Data was collected using guided interview schedules, key informant interviews, observation, and the use of periodicals, publications, and journals for secondary data. Data was summarised using pivot tables analysed using thematic analysis, percentages, mean, frequency distribution, chi-square and Pearson’s correlation coefficient between the variables. The data was then presented using text, tables and graphs. It was established that capacity building and training on technical and post-harvest management skills was not effectively done by the extension officers at the initiation stage of the projects and subsequently during the project implementation. This led to a decline in the performance of farms and a high dropout rate of farmers. As a result, the objective of ESP as far as commercialisation of aquaculture farms was not achieved. The study recommends the development of aquaculture best production management practice and integrated farmer training program across the Constituency.

The 2013 curriculum requires students to be able to learn from various learning sources, and teachers are required to be more creative in developing learning media. The observations are also made on fish breeders in the Muncul area of Semarang Regency. It is known that fish farmers do not understand fish ectoparasites, their symptoms and proper handling. Based on the results of these observations, the need for a media that can help students learn ectoparasites and a medium that can help fish farmers in overcoming ectoparasites in fish, so the Ectofishpedia is developed. Ectofishpedia is made based on ectoparasitic observations at BKIPM Semarang and literature studies. This study aims to determine the validity of Ectofishpedia, the feasibility of Ectofishpedia as a supplement for teaching materials, and the feasibility of Ectofishpedia for use by fish farmers. This study uses the R&D method by Sugiyono (2013). The validity assessment by material experts obtain a percentage score of 88.74%, and by media experts 98.75% with very valid criteria. The feasibility assessment by the teacher obtained a score score of 86.45% and 85.05% by students with very appropriate criteria. The feasibility assessment by fish farmers obtained a score of 83% with very appropriate criteria. The results of this study indicate that Ectofishpedia is valid and appropriate to use as a supplement for teaching materials for pest and disease materials and is suitable for use by fish farmers.

The first marine biological station in Canada was established in St. Andrews, New Brunswick, in July 1899. The original station was a portable laboratory and was moved between various summer research sites in Atlantic Canada before a permanent station was established in St. Andrews in 1908. Early research included practical problems in the fisheries and descriptive work of coastal fauna and was performed by university researchers. Contributions to Canadian Biology, a journal founded to report the findings of the early station's researchers, in time evolved into the Canadian Journal of Fisheries and Aquatic Sciences. For the first 75 years, the station was managed as part of the Fisheries Research Board of Canada and its predecessors, and since 1979 by the Department of Fisheries and Oceans (from 1972 to 1978, two other government departments held this responsibility). Research on fisheries, the environment, oceanography, and aquaculture has dominated the station's history. July 1999 marked the 100th anniversary of marine research in St. Andrews. We celebrate and remember with pride our accomplishments and look forward to the future of conserving Canada's aquatic environment and the livelihood of Atlantic Canadians.

The application of antibiotics are of no use, because of its ineffectiveness in many cases, or result in increases in virulence of pathogens and, furthermore, are cause for concern in promoting transfer of antibiotic resistance to human pathogens. As a remedial measure, application of gut/ intestinal probiotics as a supplement along with feed has been suggested for shrimp culture as an effective farming practice for better growth, FCR (Feed conversion ratio) and disease control. The effect of gut probiotics mixed in a feed was studied for its effect on black tiger shrimp Penaeus monodon) in the Aquaculture Department Laboratory of College of Marine Science and Technology, Massawa, Eritrea- (Northeast Africa) and was found to be effective in providing higher growth, better FCR and resistant to pathogenic infections.

Full textAbstract:
Representatives of the sturgeon family do not have pronounced external sex differences, which are typical of most aquaculture fishes. This causes some difficulties in their cultivation, the effectiveness of which largely depends on the timely division of the herd of fish into males and females, especially in caviar-commercial sturgeon farming. To date, none of the available methods for determining the sex of sturgeon is perfect. Some are traumatic, others are too expensive to use in commercial fisheries. This encourages the search for new methods and the development of effective ways to separate sturgeon by sex, which determines the relevance of research in this area. The aim of the study was to test the hypothesis of the presence of sex differences in the linear size of the tail stem in a member of the sturgeon family - sterlet (Acipenser ruthenus Linnaeus). The object of the study is the morphometric parameters of the tail stalk in the sterlet of adulthood. The subject of the study - differences in the structure of the tail of males and females of sterlet. Research methods - generally accepted in fisheries science ichthyological and statistical. The study was conducted in the training, research and production laboratory of fish farming of the Department of Aquaculture NULES of Ukraine in April and December 2019. The material for the study were the offspring of sterlet from a flock of fish kept in a closed recirculation aquaculture system of the fish farming laboratory. According to the results of the study, the hypothesis of a difference in the size of the tail stalk in male and female sterlet was not confirmed. However, according to the materials of pairwise correlation analysis of the dependence of the values of the indices of the structure of the tail stem on the age of the fish, a moderate inverse relationship was found between the relative thickness of the tail stem and the age of males and females of this fish. Females also showed an increase in the relative length of the tail stem with age. It was determined appropriate to continue similar studies on immature sterlet, aged 2 to 5 years.

The present study was conducted to reveal the present scenario, problems and the prospect of fish farming of Gazipur Sadar upazila Bangladesh. The primary data were collected through field survey, questionnaire interview and focus group discussion from the fish farmers of several villages and urban areas of the upazila. Secondary data were collected from the Department of Fisheries and aquaculture extension section. Gazipur Sadar upazila has 14462.42 ha potential fisheries resources of which floodplains, seasonal water bodies, and ponds comprise 71.01%, 13.04%, and 8.57%, respectively. The total fish production of the upazila in 2016-17 was 14492.7 MT, 27% of the Gazipur district. The highest fish production of 5436 MT and 4.39 MT/ha/year came from the pond sector. Among different pond culture systems, the semi-intensive system had the highest fish production output (2826 MT). Exotic carps were the highest produced fish in the ponds. However, in spite of comprising a huge proportion of seasonal floodplains the fish production from this sector was only 0.42 MT/ha/year in 2016-2017. This indicates the poor utilization of inland open water resources for fish production in the study area. The major areas were identified to improve the existing pond fish farming situation were access to low-interest loan, quality seed, supply of advanced technologies, need-based training, and marketing facilities. Along with improving the pond fish farming, community-based fisheries management and some aquaculture initiatives on private own seasonal floodplains should be taken on a priority basis to improve open water management and to flourish inland fish production in the study area.Progressive Agriculture 29 (1): 53-63, 2018

Full textAbstract:
Whenever a new organism comes on the aquaculture scene there is a rush to try it out and to introduce the species to new locations. Such was the case with Pacifastacus leniusculus in Europe in the early 1980s. In the UK there was at the time no legislation to control such introductions and commercial pressures ensured that the species was soon widely distributed throughout the UK. One consequence was the introduction of the Crayfish Plague Aphanomyces astaci which resulted in the destruction of large populations of the native crayfish Austropotamobius pallipes in several river systems. It was against this background that I came to learn of a proposal to introduce Cherax quadricarinatus to Fiji in 1991. The commercial proposal was put to the Department of Fisheries who were considering accepting it when, on the basis of experience with crayfish in the UK, I proposed that there should be a delay while the species was evaluated for its likely effect on the Fijian fauna.

This study was conducted to measure the water quality parameters of old Brahmaputra River in Mymensingh district near Bangladesh Agricultural University to determine the water quality index (WQI) of the River Brahmaputra. Water quality focuses on various aspects of the physico-chemical parameters by which the quality of the water body can easily be elucidated. Three different locations were selected within the study area. Water samples were collected in April 2015 from these three locations along the river and analyzed for these physico-chemical parameters: pH, Dissolve Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Ammoniacal Nitrate (AN), Suspended Solids (SS). The values of these parameters were used to calculate the WQI based on the equation derived by the Department of Environment (DoE) Malaysia. The WQI was found to be 57.58, which falls in the class IV category and means that the water is very polluted and as of April 2015, this water is not suitable for public water supply, not suitable for recreational purpose, has limited potential for aquaculture but is suitable for irrigation.Progressive Agriculture 27 (3): 355-361, 2016

(Annelida: Eunicida: Eunicidae), is described from the Marine Annelids Hatchery of the Southeast Asian Fisheries Development Center, Aquaculture Department (SEAFDEC- AQD), Iloilo Province, Philippines. It represents the first record of this group in the Philippines. The new species is most similar morphologically to M. hongkongensa Wang, Zhang & Qiu, 2018, but can be distinguished from it by having fewer branchial filaments, a pair of faint eyes (absent in M. hongkongensa), and in slight differences in jaw morphology and chaetation. The embryos of the new species develop inside a jelly cocoon attached to the entrance of the adult burrow; this is the first time that egg-containing cocoons have been found in any species of the sanguinea-group. Phylogenetic analysis based on the mitochondrial gene cytochrome c oxidase subunit I (COI) revealed that Marphysa iloiloensis n. sp. is genetically distinct from all other analysed Marphysa species and forms a sister group to M. hongkongensa. A revised identification key to members of the sanguinea-group in Southeast Asia is provided.

The target line graph and the realization of regional revenues indicate that the targets have to be achieved are still far, because until June 2017 achievement only Rp. 56,950,403,904.02, - while the target to the end of December 2017 is Rp. 484,520,000,000. To achieve the annual target as expected need a strategy. Association analysis is also known as one of the data mining techniques basis of various other mining data techniques. By using the Apriori Algorithm, an analysis of the obstacles in achieving targets can be done to find interesting rules that are useful in supporting the system of achieving local tax targets. The implementation of Association Rule to support the achievement of the tax target is expected to help the process of achieving the target of regional income tax, especially in the Regional Revenue Department of Deli Serdang Regency.

The pH of waters is one of external factors that is important for succesfull of hatching percentage of fish eggs. The pH stimulates the chorionase enzyme become more active that can softens the egg chorion. The aim of this study was to determine the optimum pH value for hatching of catfish eggs. This research has been conducted in Fisheries Basic Laboratory, Department of Aquaculture, Department of Fisheries, Agriculture Faculty, Universitas Sriwijaya from August 31st to September 16th, 2019. The research metehod used Completely Randomized Design with five treatments and 3 replications. The treatments are P1 (pH of 5±0.2), P2 (pH of 6±0.2), P3 (pH of 7±0.2), P4 (pH of 8±0.2) dan P5 (pH of 9±0.2). The results showed that different value of water pH gave significant effect on hatching percentage, hatching time and survival rate of catfish larvae but did not significant effect on percentage of abnormal larva. The highest hatching percentage (80.33 %) was in treatment of pH 7 ± 0.2 (P3), the fastest hatching percentage (21.59 hours) was in treatment of pH 8 ± 0.2 (P4), the highest survival rate of catfish larvae (99.44 %) was in treatment of pH 7 ± 0.2 (P3) and the highest percentage of abnormal larvae (2.22 %) was in treatment pH 5 ± 0.2 (P1). During the research, water quality were in tolerance range for hatching and rearing of eggs and larvae catfish i.e. temperature of 26.2 – 27.9 oC, dissolved oxygen of 4.7 – 5.5 mg.l-1, and ammonia of 0.22 – 0.47 mg.l-1.Keyword : Hatching eggs, catfish, pH value

Full textAbstract:
An experiment was carried out to comparative analysis of nutritional quality of different fish feed from different feed dealers and industries in greater Noakhali region and to compare the values with those provided by the manufacturers. The feed samples were collected from different feed industries and dealer's shop of these region. Feed samples were collected during 10 August to 5 September, 2016. The collected feed samples were stored and analyzed in the Fish Nutrition Laboratory of the Department of Aquaculture in the Faculty of Fisheries, Bangladesh Agricultural University (BAU), Mymensingh for proximate composition (moisture, ash, crude protein, crude lipid, crude fiber, carbohydrate) following standard methods. Results showed that there was significant variation between analyzed and company provided nutritive values of different feeds. Some feed samples have low moisture level (difference 0.7 to 3.3%). Ash content of the experimental samples also show a variety of results compared to their labeled composition. Only some feed have more values to the company provided values, such as, Mega starter (12.13%) and Bengal grower (12.75) proportion with 12%. Some feed contains more difference range of 6.01% more than labeled values is RP feed (20.01%). Maximum feed samples had lower crude protein (difference 0.05 to 4.65%) than the company provided protein values. However, only crude protein of Bengal finisher (29.95%) and Aftab grower (28.07%) feeds were found to be almost same to the company provided nutritive values (30% and 28%). The lipid, ash and carbohydrates contents of the experimental samples also have a difference range. The highest lipid values are available in Provita starter (9.76%) and lowest values containing feed Setu grower (4.33%). The highest carbohydrates content in the feed Provita starter (36.84%). The findings of this study demonstrated that low quality commercial fish feeds were supplied to the fish farmers by majority of feed companies. Therefore, the study will generate some information to the farmers which will help to choose the best feed for their aquaculture production.

Full textAbstract:
A triplicate experiment was conducted to evaluate the supplementation of monosodium glutamate into the diet on physiological responses, growth performances, and feed efficiency of north African catfish Clarias gariepinus cul-tured in high ammonia environment. A hundred fish with an initial body weight of 11.9±0.3 g was rearing for 60 days without any water exchange in nine plastic tanks (1x1x1 m3) at experimental pond of Department of Aquaculture, Bogor Agricultural University. During rearing period, fish were fed on the diet supplemented with 0%, 0.87%, or 1.74 % of monosodium glutamate, two times a day at satiation. Result shows that the supplementation of monoso-dium glutamate in feed stimulates change in fish physiological responses such as lower Alanin Transaminase mono-sodium glutamate enzyme activity, lower blood ammonia, and higher intestinal glutamine. Feeding using monoso-dium glutamate-supplemented feed at three different doses results in the same growth rate. However, the highest feed efficiency of North African catfish was recorded in the treatment of feed supplemented with 0.87% monosodium glutamate. Thus, it can be inferred that the usage of monosodium glutamate may improve physiological response and feed efficiency but does not affect fish growth rate.

Abstract The article contains preliminary report of field study conducted in February 2006 in Las Huastecas Region in Mexico by members of the Department of Regional Studies on Latin America at the Faculty of Geography and Regional Studies of Warsaw University. The aim of the research was to determine changes in socio-economic patterns of Las Huastecas rural areas, as well as to grasp the way local inhabitants perceived them. Open and semi-structured interviews were held with local authorities and inhabitants, in many cases with the same persons that were interviewed during the previous research trip in 2001. Conclusions deal with such aspects of Las Huastecas reality, as further improvement in social and technical infrastructure, intensification of diversification of revenues including short and medium temporal migration to big cities in northern parts of Mexico as well as seasonal migration of rural labor to agribusiness sector. Some limited new initiatives related to small scale tourism, preservation of cultural heritage and aquaculture were also observed. The local inhabitants perceived their actual situation as more difficult than 5 years ago, but we have impression that many of social actors have been more active during this period.

The aim of the study was to present the history of ichtyopathology in Poland and the main achievements of researchers who developed this discipline. The pioneer of ichtyopathological research in Poland was the ichtyologist prof. Teodor Spiczakov, founder of the first Fish Diseases Laboratory at the Jagiellonian University (JU) and initiator of fishery veterinary service. After the Second World War, dr Stanisław F. Śnieszko, a researcher from JU, established a laboratory in the United States, renamed the National Fisheries Center in 1977. In writing about the beginnings of ichthyopathology in Poland, one must also mention prof. Bronisław Kocyłowski, founder and head of the Department of Fish Diseases at PIW in Puławy and lecturer at the Warsaw University of Life Sciences (WULS) and Maria Curie Skłodowska University in Lublin. Prof. Eugeniusz Grabda also contributed to the development of ichtyopathology. He headed the Inland Fisheries Institute (IFI), Fish Disease Laboratory and the Department of Ichthyology with the Department of Fish Diseases at the Fishery Department of the Academy of Agriculture and Technology (AAT) in Olsztyn and co-founded the Department of Marine Fisheries at the Agricultural Academy and the Department of Fish Diseases in Szczecin. In Żabieniec near Warsaw, IFI established a new Ichtiohygiene Division, renamed the Division of Pathology and Fish Immunology, formerly headed by prof. Maria Studnicka and now by prof. Andrzej K. Siwicki. Veterinary inspection in Poland is conducted by the Fish Diseases Laboratory at ZHW under the substantive supervision of the National Veterinary Research Institute & National Reference Laboratories at Fish Diseases Unit in Puławy, headed by prof. Jerzy Antychowicz. Currently the Unit is the National Reference Laboratory for the diagnostics of diseases of aquaculture animals, run by prof. Michal Reichert. Prof. J. Antychowicz and dr. Jan Żelazny taught for many years at the Faculty of Veterinary Medicine at the WULS in Warsaw and at AAT in Olsztyn. The Polish Academy of Sciences has a Department of Ichtiopatology and Fishery Management in Gołysz, headed by prof. Andrzej Pilarczyk, who studies the biological basis of fish farming. “Fish diseases” is a mandatory subject at faculties of veterinary medicine in Poland, and every graduate of veterinary medicine possesses a basic knowledge in this field. The Division of Fish Diseases and Biology in Lublin has been operating since 1963 and for many years was headed by prof. Maria Prost, an authority on the parasitology of fish. The current head of the Division is prof. Antonina Sopińska. The Division of Hygiene Veterinary Laboratory and Fish Diseases Laboratory (later Division of Ichtyopathology) at the Faculty of Veterinary Medicine, Wrocław University af Environmental and Life Sciences were previously headed by prof. Zbigniew Jara, and now by dr Wiktor Niemczuk. At the University of Warmia and Mazury in Olsztyn, prof. Andrzej K.

Full textAbstract:
The Zapatosa marsh (ciénaga de la Zapatosa) is located in the Department of Cesar in Colombia. In 2018, the muddy complex of Zapatosa was declared a Ramsar wetland, for this reason, it is necessary to develop management strategies for the marsh that allow not only the conservation of the ecosystem. The objective of this work is to use System Dynamics as an evaluation tool for three possible management scenarios of artisanal fishing in the Zapatosa marsh. A qualitative causal diagram and a quantitative Stock and Flow diagrams were designed to describe the dynamics of fish and fishermen populations in the marsh. The initial model setting and parametrization derived from values gathered from different sources of information. The calibration of the model was carried out with reference data on total catch of kilograms of fish and population data from the Department of Cesar. The data obtained through the “Aquaculture and artisanal fisheries survey of the Department of El Cesar” in 2018 were reproduced in the model and then compared with 3 alternative management scenarios. Scenario 1 included strictly applying of the fishing stopover for the species Prochilodus magdalenae and for catfish (Pseudoplatystoma magdaleniatum, Pimelodus blochii y Sorubim cuspicaudus). Scenario 2 considered to apply the same prohibitions, but with a payment to fishermen for the care of the swamp at the time of prohibition. In Scenario 3 the fishermen under fishing stop will receive an income of a legal Colombian minimum monthly salary and will be engaged in practices of ecosystem services. Results showed that in some scenarios the economic situation of the fishermen is unable to meet the monthly family expenses in different periods of the year. On the other hand, there is greater economic stability and fish populations when adopting Scenario 3, but it is difficult to achieve in the short or medium term. Scenario 2 shows little recoveries in fish populations and a higher money availability to the local community than in Scenario 3, in certain months, presenting the best short-term management option. The presented model encourages further simulation scenarios of the Zapatosa Marsh.

Full textAbstract:
The study was conducted to determine the socioeconomic characteristics and constraints of participatory pond fish farmers in Muktagachha upazila (sub-district) under Mymensingh district of Bangladesh. Data were collected by using a structured interview schedule during 01 to 31 October 2018 from a sample of 100 fish farmers (50% of total population) who were selected randomly from a population of 200. Data were analyzed using descriptive statistics, rank order and coefficient of correlation. The majority of the participatory pond fish farmers (90%) faced medium to low constraints. Among 22 constraints, lack of training on aquaculture was identified as the most critical one, followed by high price of various inputs. The least important constraint of the farmers was crisis of water in dry season. It was revealed that fish farming experience, annual family income and training exposure were significantly associated with the constraints of participatory pond fish farmers. It is therefore recommended that the Department of Fisheries (DOF) and other related organizations can offer credit facilities, proper training and suitable extension services to minimize the constraints of participatory pond fish farmers and meet the increasing demand of fish in Bangladesh.
