Abstract:

AbstractObjective:Aquaculture is one of the fastest-growing food production sectors in many low-income and food-deficit countries with aquatic ecozones. Yet its specific impact on nutrition and livelihood in local communities, where commercial and/or export-orientated aquaculture activities are developed, is largely unknown.Design:The present narrative and argumentative review aims to provide an overview of our current understanding of the connections between aquaculture agroecosystems, local and national fish production, fish consumption patterns and nutrition and health outcomes.Results:The agroecological dynamic in a coastal-estuarine zone, where the aquatic environment ranges from fully saline to freshwater, is complex, with seasonal and annual fluctuations in freshwater supply creating a variable salinity gradient which impacts on aquatic food production and on food production more generally. The local communities living in these dynamic aquatic ecozones are vulnerable to poverty, poor diet and health, while these ecosystems produce highly valuable and nutritious aquatic foods. Policies addressing the specific challenges of risk management of these communities are limited by the sectoral separation of aquatic food production – the fisheries and aquaculture sector, the broader food sector – and public health institutions.Conclusions:Here we provide an argument for the integration of these factors to improve aquaculture value chains to better address the nutritional challenges in Bangladesh.

Abstract:

Aquaculture is a rapidly expanding and extremely diverse form of animal production. Aquaculture takes place in systems that cover an enormous range of levels of intensification from extensively managed low input static ponds to super-intensive high exchange rate silos with liquid oxygen injection. Appropriate nutritional strategies are required for each level of intensification.

Abstract:

Agro-industrial wastes pose great economic and environmental hazards, while the economic success of aquaculture is threatened by the unsustainability of fishmeal use. The aims of the present study were to bio-convert agro-industrial wastes through vermicomposting, and then evaluate the potential of the by-products in promoting aquaculture nutrition. Coffee husks (CH), barley wastes (BW), and kitchen wastes (KW) were pre-composted and inoculated with earthworms, Eisenia fetida, and then vermicomposted for 70 days under a controlled environment. The vermicomposting by-products, i.e., earthworms and vermicast, were amalgamated in the ratio of 1:5 into bedding and then analyzed. There were neither earthworm mortalities nor significant difference (P>0.05) in cocoons produced by E. fetid in all treatments. The earthworms grown in KW attained the highest average weight gain of 27.8±0.7g, followed by CH (24.9±0.6g) and BW (24.8±0.7g). Earthworms grown in CH and BW had significantly higher (P<0.05) nutritional attributes. All experimental wastes produced vermicast with carbon and nitrogen ratios within the preferred agronomic limit of 20. The nutritional profile of the BW bedding was comparable with that of Caridina nilotica meal and was within the recommended dietary requirements of fish. The wastes can be bio-converted through vermicomposting into various forms appropriate for providing aquaculture nutrition.

Abstract:

The shortage of wild fishery resources and the rising demand for human nutrition has driven a great expansion in aquaculture during the last decades in terms of production and economic value. As such, sustainable aquaculture production is one of the main priorities of the European Union’s 2030 agenda. However, the intensification of seafood farming has resulted in higher risks of disease outbreaks and in the increased use of antimicrobials to control them. The selective pressure exerted by these drugs provides the ideal conditions for the emergence of antimicrobial resistance hotspots in aquaculture facilities. Omics technology is an umbrella term for modern technologies such as genomics, metagenomics, transcriptomics, proteomics, culturomics, and metabolomics. These techniques have received increasing recognition because of their potential to unravel novel mechanisms in biological science. Metagenomics allows the study of genomes in microbial communities contained within a certain environment. The potential uses of metagenomics in aquaculture environments include the study of microbial diversity, microbial functions, and antibiotic resistance genes. A snapshot of these high throughput technologies applied to microbial diversity and antimicrobial resistance studies in aquacultures will be presented in this review.

Abstract:

The relationship between aquatic foods and food nutrition and security is increasingly recognised in policy and practice, yet many governance instruments do not acknowledge or support this important connection. The most effective policy approaches to support the link between these sectors, or ‘best practices’ are currently unknown. We reviewed relevant governance instruments from multiple countries to identify how these instruments linked fisheries, aquaculture and food security and nutrition, including the policy framing and evidence of political commitment. Of the documents connecting the sectors (65%), the majority did so in the context of developing the fisheries/aquaculture sector to increase aquatic food availability and/or access (51%), followed by developing the fisheries/aquaculture sector as a livelihoods approach to indirectly improve food security (33%), for example, through income generation. Sectoral links established in the context of nutrition-sensitive approaches to fisheries and aquaculture were less common (5%). Almost one third (29%) of instruments supported the connection between aquatic foods and food security and nutrition across three or more different contexts relevant to food security or food systems, while 12% indicated a very high level of commitment. We recommend some key attributes for future policy development to help build coherence between sectors and to help frame coherent food system-based policies.

Abstract:

Uncontrolled use of antibiotics in aquaculture caused the appearance and spreading of pathogens resistance to antibiotics, what consequently drove up to the necesity of finding new technologies for protecting aquatic organisms from pathogens. Probiotics are aimed to reduce antibiotics application, and furthermore they have an important role not only in disease prevention but also in efficiency of food utilization and improvement of production parameters. Carp fish species are economically most significant in Republic of Serbia, therefore this work summarizes the results of previous studies of antibiotics application in this kind in particular. There is also pointed out to numerous harmful side effects of antibiotics use in aquaculture, and described the previous results of investigations on mechanism of probiotics effects and specificity of their use in this field as well. Beside this, there are summarized the results that show positive influence of probiotics in cyprinides nutrition on production performance, haematological parameters, course of experimental infection, activity of digestive enzymes. Special attention is paid to criteria for proper selection of probiotics in cyprinides production.

Full text

Abstract:

An estimated two billion people worldwide currently suffer from micronutrient malnutrition, and almost one billion are calorie deficient. Providing adequate nutrition is a growing global challenge. Seafood is one of the most important sources of both protein and micronutrients for many, yet production from wild capture fisheries has stagnated. In contrast, aquaculture is the world’s fastest-growing food production sector and now supplies over half of all seafood consumed globally. Mariculture, or the farming of brackish and marine species, accounts for roughly one-third of all aquaculture production and has received increasing attention as a potential supplement for wild-caught marine fisheries. By analyzing global patterns in seafood reliance, malnutrition levels, and economic opportunity, this study identifies where mariculture has the greatest potential to improve human nutrition. We calculate a mariculture opportunity index for 117 coastal nations by drawing on a diverse set of seafood production, trade, consumption, and nutrition data. Seventeen primary variables are combined into country-level scores for reliance on seafood, opportunity for nutritional improvement, and opportunity for economic development of mariculture. The final mariculture opportunity score identifies countries with high seafood reliance combined with high nutritional and economic opportunity scores. We find that island nations in Southeast Asia and the Caribbean are consistently identified as countries with high mariculture opportunity. In other regions, nutritional and economic opportunity scores are not significantly correlated, and we discuss the implications of this finding for crafting appropriate development policy. Finally, we identify key challenges to ameliorating malnutrition through mariculture development, including insufficient policy infrastructure, government instability, and ensuring local consumption of farmed fish. Our analysis is an important step towards prioritizing nations where the economic and nutritional benefits of expanding mariculture may be jointly captured.

Abstract:

Despite aquaculture being hailed as the fastest growing farming sector in the world, South African aquaculture is still lagging behind. This article aims to highlight challenges (mostly beyond their control) that South Africa’s emerging aquaculture entrepreneurs have to endure in order to find a breakthrough into the industry. Availability of necessary resources such as land, water, infrastructure,financial support and access to markets, as well as crime are among challenges faced by these entrepreneurs on a daily basis. Limited human resources in capacity building, skills and aquaculture expertise also hinders the development and expansion of aquaculture in South Africa. Complex legislation governing aquaculture further limits the development of this sector to prospective investors. Fish and machinery theft in fish farms has an adverse effect, which had resulted in many enterprises closing down in recent years. South Africa is not a traditional fish-eating nation and this phenomenon has seen many emerging entrepreneurs struggling to locally commercialize their produce. It is well known that fish consumption provides human nutrition with essential nutrients necessary for normal body function. Thus,aquaculture has the potential to contribute to food and nutrition security and alleviate poverty in rural communities. However, plenty of initiatives need to be developed by government and the private sector to develop a sustainable aquaculture industry. These initiatives should involve the establishment of an aquaculture friendly legislation that would support emerging aquaculture entrepreneurs. Several financial institutions view aquaculture as a high-risk business,and as a consequence,decline financial support or loan requests from emerging farmers.Focused research as a strategic initiative to develop aquaculture species that would be first priority for local markets is encouraged. This article explores the challenges facing emerging entrepreneurs and suggests possible solutions that might assist in the development of the aquaculture sector in South Africa. We postulate that constructive and regular engagements between the government and private sector is a key to a sustainable and prosperous aquaculture sector in South Africa.

Abstract:

With the growing importance of aquaculture worldwide, characterization of the microbiota of high-value aquaculture species and identification of their shifts induced by changes in fish physiology or nutrition is of special interest. Here we report the first 16S rRNA gene metabarcoding survey of the mid-intestinal bacteria of Chinook salmon (Oncorhynchus tshawytscha), an economically important aquacultured species. The microbiota of 30 farmed Chinook salmon from a single cohort was surveyed using metabarcode profiling of the V3-V4 hypervariable region of the bacterial 16S rRNA gene. Seawater, feed and mid-intestinal samples and controls were sequenced in quadruplicate to assess both biological and technical variation in the microbial profiles. Over 1000 operational taxonomic units were identified within the cohort, providing a first glimpse into the mid-intestinal microbiota of farmed Chinook salmon. The taxonomic distribution of the salmon microbiota was reasonably stable, with around two thirds of individuals dominated by members of the family Vibrionaceae. We anticipate that the workflow presented in this paper could be applied in other aquacultured fish species to capture variation or dysbiosis occurring as a result of changes in feed, health or environmental conditions.

Abstract:

Aquaculture production in China has made large contributions to the global total volume of fish for human consumption. The developed mariculture fish species large yellow croaker (Pseudosciaena crocea) is the highest economic marine fish of China. As a schooling fish, large yellow croaker (LYC) usually migrates from northeast China to the southeast seacoast to over-winter. Indeed, there are several culture systems that can be applied for large yellow croaker, which should simulate the natural habitat for this fish species. The nutrition management of LYC has attracted researchers to study their nutrient requirements, growth, and other physiological characteristics. Here, we review the general biology (geographic distribution and habitat), hatchery development, aquaculture systems, and nutrition management of LYC. The paper aims to underpin the most significant investigations and highlight the future prospects for the LYC aquaculture industry in China.

Abstract:

Abalone aquaculture attracts wide attention nowadays because of its high market value and depleted of wild stocks. China and Japan are the main producer of abalone from aquaculture followed by other countries such as New Zealand, Australia and US. Most of cultured abalone are temperate species but considerable research efforts have been made to culture tropical abalone in the Philippines, Thailand, and Indonesia. Most of abalone culture still depends on natural food but recent studies have been conducted to develop artificial diet for abalone. This will not only reduce wild harvest of macrolagae but also develop high nutrition diet at low cost. Successful abalone aquaculture is determined by correct nutrition supplement in the diet. As other cultured animal, abalone requires balanced nutrition of carbohydrate, protein, lipid, vitamins, and minerals. As herbivores, abalone can utilize carbohydrate efficiently as energy source and thus only requires low level of protein (range from 27%—40%). Lipid requirements range from 3%—5% while some minerals such as calcium and phosphorus in artificial feed are only needed in small amount, 0.5% of calcium in diets and 0.7% of phosphorus in the diet can improve the growth rate of abalone. There is not available information of vitamin upplementation in the diet but it is suggested that natural food meets the requirement.

Abstract:

Over the last decades, aquaculture production increased rapidly. The future development of the industry highly relies on the sustainable utilization of natural resources. The need for improving disease resistance, growth performance, food conversion, and product safety for human consumption has stimulated the application of probiotics in aquaculture. Probiotics increase growth and feed conversion, improve health status, raise disease resistance, decrease stress susceptibility, and improve general vigor. Currently, most probiotics still originate from terrestrial sources rather than fish. However, host-associated (autochthonous) probiotics are likely more persistent in the gastrointestinal tract of fish and may, therefore, exhibit longer-lasting effects on the host. Probiotic candidates are commonly screened in in vitro assays, but the transfer to in vivo assessment is often problematic. In conclusion, modulation of the host-associated microbiome by the use of complex probiotics is promising, but a solid understanding of the interactions involved is only in its infancy and requires further research. Probiotics could be used to explore novel ingredients such as chitin-rich insect meal, which cannot be digested by the fish host alone. Most importantly, probiotics offer the opportunity to improve stress and disease resistance, which is among the most pressing problems in aquaculture.

Abstract:

Dietary composition of aquaculture feeds (aquafeeds) determines the quality of wastes from aquaculture production systems. These wastes, which are derived mainly from nitrogenous and phosphorus compounds subsequently affect water quality in the culture systems and the ambient environment. Depending on the type of culture systems and management practices employed, the aquafeed wastes can influence the water pH, algal turbidity, biological oxygen demand (BOD) and may cause fish mortality. The aquafeed wastes also can facilitate eutrophication leading into harmful algal blooms. Moreover, large quantities of aqua-waste are discharged as fish cannot retain all the food they consume which means a significant portion of the feed remains uneaten. In this paper, we review and discuss practical nutritional strategies and mitigation measures to reduce aquafeed wastes including controlled formulation using high-quality ingredients, enzyme-based aquafeed, processing, reduction of anti-nutrition factors and precision feeding. The paper further recommends strategies for enhancing the resilience of aquaculture production systems and mitigation measures to reduce the effects of aqua-wastes on ambient natural environments.

Abstract:

Abstract Food security is the main path to develop the socioeconomic status in any country in the world to defeat malnutrition. The present scenario in an under developed countries are still facing this problem. Hence the human nutrition deficiencies focus on the importance of animal protein in their regular diet. To overcome this problem, fisheries contribute a significant amount of animal protein to the diets of people worldwide. The aquatic animals are the highly nutritious and cheapest protein sources, which serves as a valuable supplement in diets by providing essential vitamins, proteins, micronutrients, and minerals, for the poor people. Aquaculture is playing a vital role in the developing countries in national economic development, and global food supply. Food and agricultural organization (FAO) declared that this aquaculture has the continuous potentiality to create a developmental goals for the country economy and better human welfare.

Abstract:

The status and potential of aquaculture is considered as part of a broader food landscape of wild aquatic and terrestrial food sources. The rationale and resource base required for the development of aquaculture are considered in the context of broader societal development, cultural preferences and human needs. Attention is drawn to the uneven development and current importance of aquaculture globally as well as its considerable heterogeneity of form and function compared with established terrestrial livestock production. The recent drivers of growth in demand and production are examined and the persistent linkages between exploitation of wild stocks, full life cycle culture and the various intermediate forms explored. An emergent trend for sourcing aquaculture feeds from alternatives to marine ingredients is described and the implications for the sector with rapidly growing feed needs discussed. The rise of non-conventional and innovative feed ingredients, often shared with terrestrial livestock, are considered, including aquaculture itself becoming a major source of marine ingredients. The implications for the continued expected growth of aquaculture are set in the context of sustainable intensification, with the challenges that conventional intensification and emergent integration within, and between, value chains explored. The review concludes with a consideration of the implications for dependent livelihoods and projections for various futures based on limited resources but growing demand.

Abstract:

As the most diverse vertebrate group and a major component of a growing global aquaculture industry, teleosts continue to attract significant scientific attention. The growth in global aquaculture, driven by declines in wild stocks, has provided additional empirical demand, and thus opportunities, to explore teleost diversity. Among key developments is the recent growth in microbiome exploration, facilitated by advances in high-throughput sequencing technologies. Here, we consider studies on teleost gut microbiomes in the context of sustainable aquaculture, which we have discussed in four themes: diet, immunity, artificial selection and closed-loop systems. We demonstrate the influence aquaculture has had on gut microbiome research, while also providing a road map for the main deterministic forces that influence the gut microbiome, with topical applications to aquaculture. Functional significance is considered within an aquaculture context with reference to impacts on nutrition and immunity. Finally, we identify key knowledge gaps, both methodological and conceptual, and propose promising applications of gut microbiome manipulation to aquaculture, and future priorities in microbiome research. These include insect-based feeds, vaccination, mechanism of pro- and prebiotics, artificial selection on the hologenome, in-water bacteriophages in recirculating aquaculture systems (RAS), physiochemical properties of water and dysbiosis as a biomarker.

Abstract:

Concerning the increasing global demand for food and accumulation of huge amounts of biomass waste from the agro-food industry whose manipulation is usually inadequate, the potential of livestock to convert by-products as alternative feed ingredients into valuable proteins has been proposed as an outstanding option. Soybean molasses present a by-product of soybean protein concentrate production with low commercial cost but high nutritive and functional value. It is a rich source of soluble carbohydrates in the form of sugars and soybean phytochemicals. Therefore, this paper provides a review of published works about the production of soybean molasses, chemical composition, and nutritive value. In addition, the possibility of the application of soybean molasses in animal nutrition as a pelleting aid and functional feed ingredient is also discussed. Special attention is devoted to the influence of the inclusion of soybean molasses in the diets for ruminants, non-ruminants, and aquaculture on animal performance and health.

Abstract:

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.

Abstract:

The objective of this study was capacitate aquaculture farmers and develop social technologies for the culture of tambaqui (Colossoma macropomum) in the archipelago of Marajó (Pará - Brazil). The study was carried out in the municipality of Curralinho by the Federal Institute of Education, Science and Technology of Pará (IFPA) Campus Breves, in March 2020. Two structured questionnaires were applied to 13 course participants who participated in the training. The first was before the course, about fish farming and the adoption of Good Management Practices (BPM) adopted by aquaculture farmers in the Marajó region. The second, composed of closed questions to evaluate the training course, whose themes were: 1) water quality, 2) indicated species, 3) fish transport management, 4) fish quarantine and stock, 5) fish biometrics, 6) liming and fertilizing ponds, 7) management of fish nutrition and health, and 8) fish harvesting and slaughter, were approached in the course. At the end of the lectures / training, a workshop for the production of social technologies was conducted, among students, teachers and aquaculture farmers. Previous knowledge about fish farming and the adoption of BPM were essential for the effectuation of the course. Issues about water quality, biometrics and fish nutrition and health were the ones that called the most attention from aquaculture farmers. Secchi's disk, ichthyometer, hand net and net-tank were the social technologies built. Post-course evaluation was essential to understand the impact of the socialization of knowledge provided to the community. In conclusion, the project reinforced teaching, research and extension actions, involving the community in favor of strengthening aquaculture in the Marajó island, Pará, Brazil.

Abstract:

Increased intake of animal-source foods (ASFs) is crucial to tackle multiple nutritional challenges in Bangladesh, and contribute to achieving targets under the Sustainable Development Goals (SDGs). Qualitative and quantitative data were collected to assess current ASFs intake behaviors and preferred ASFs, among three types of households, namely 1. aquaculture intervention (AI); 2. aquaculture non-intervention (ANI); and 3. non-aquaculture non-intervention (NANI) households and children aged 6–59 months, to understand whether intake of ASFs vary by the types of households. Purposive sampling was conducted to obtain a total of 100 households (AI, 50; ANI, 25; NANI, 25). Fish was the most commonly consumed (52.2–61.5%) and preferred (73.9–84.6%) ASF by the majority households, across study groups; although amount (mean ± SD) of intake (g/d/person) by NANI households was statistically significantly lower (NANI, 105.5 ± 53.3; p < 0.001), compared to other two groups (AI, 163.6 ± 64.7 and ANI, 159.6 ± 53). Fish species selection for household consumption was led by taste, health benefits, availability, and price. Pangasius was the first fish species of choice fed to children, due to having fewer small bones compared to other commonly consumed fish species. Dietary interventions to prioritize fish, in targeting increased intake of ASFs among study population, for improved food and nutrition security.

Abstract:

The rapid development of aquaculture production throughout the world over the past few decades has led to the emergence of new scientific challenges to improve fish nutrition. The diet formulations used for farmed fish have been largely modified in the past few years. However, bottlenecks still exist in being able to suppress totally marine resources (fish meal and fish oil) in diets without negatively affecting growth performance and flesh quality. A better understanding of fish metabolism and its regulation by nutrients is thus mandatory. In this review, we discuss four fields of research that are highly important for improving fish nutrition in the future: ( a) fish genome complexity and subsequent consequences for metabolism, ( b) microRNAs (miRNAs) as new actors in regulation of fish metabolism, ( c) the role of autophagy in regulation of fish metabolism, and ( d) the nutritional programming of metabolism linked to the early life of fish.

Abstract:

AbstractThis review aimed to place crustacean research on in vivo protein synthesis into a broader context, assess its potential for providing further insights into crustacean nutrition and physiology, and recommend future directions relevant to crustacean aquaculture. In crustaceans the flooding dose measurement of protein synthesis is the only method that has been used, it is relatively complex, time consuming and uses radioactive labels. Protein synthesis provides a subtle approach to assessing imbalances and deficiencies in dietary amino acid and energy. In addition, the calculation of protein synthesis retention efficiency (SRE) is recommended in order to understand and optimize parameters such as feeding regime and diet composition. For prawns, SRE was highest at optimum dietary protein content and quality. Similarly the most efficient feeding regimes in juvenile lobsters were demonstrated by the highest efficiency of retaining synthesized protein. Understanding how various abiotic and biotic factors influence protein synthesis has great potential for improving different aspects of crustacean aquaculture but very few studies have done this; better knowledge of how abiotic and biotic factors affect crustacean protein synthesis will contribute to optimising growth of crustaceans in culture.

Abstract:

AbstractThe international development community is off-track from meeting targets for alleviating global malnutrition. Meanwhile, there is growing consensus across scientific disciplines that fish plays a crucial role in food and nutrition security. However, this ‘fish as food’ perspective has yet to translate into policy and development funding priorities. We argue that the traditional framing of fish as a natural resource emphasizes economic development and biodiversity conservation objectives, whereas situating fish within a food systems perspective can lead to innovative policies and investments that promote nutrition-sensitive and socially equitable capture fisheries and aquaculture. This paper highlights four pillars of research needs and policy directions toward this end. Ultimately, recognizing and working to enhance the role of fish in alleviating hunger and malnutrition can provide an additional long-term development incentive, beyond revenue generation and biodiversity conservation, for governments, international development organizations, and society more broadly to invest in the sustainability of capture fisheries and aquaculture.

Abstract:

Ensuring aquafeeds meet the expected nutritional and physical specifications for a species is paramount in research and for the industry. This study aimed to examine the feasibility of predicting the proximate composition and starch gelatinisation (or cook) of aquaculture feeds (aquafeeds) regardless of their intended target species by near infrared (NIR) spectroscopy. Aquafeed samples used for nutrition experiments on various aquatic species with different nutritional requirements, as well as aquafeeds manufactured under varying extrusion conditions and steaming time to generate variable starch cook were used in this study. The various size pellets were ground before scanning by NIR spectroscopy, then models were developed to estimate dry matter, ash, total lipid, crude protein, and gross energy as well as starch cook. Proximate prediction models were successfully produced for diets with R2 values between 0.88 and 0.97 (standard error of cross-validation (SECV) 0.43 to 1.46, residual predictive deviation (RPD) 4.6 to 15.6), while starch cook models were produced with R2 values between 0.91 and 0.97 (SECV 3.60 to 5.76, RPD 1.2 to 1.9). The developed NIR models allow rapid monitoring of the nutritional composition, as well as starch cook, one of the major physical properties of aquafeeds. Models that provide rapid quality control assessment of diet characteristics is highly desirable in aquaculture research and the aquafeed industry.

Abstract:

In Bangladesh, aquaculture is critically important in terms of providing food and nutrition, sustainable livelihoods, income, and export earnings. Nevertheless, aquaculture in Bangladesh has faced recent concerns due to climate change. Aquaculture is vulnerable to a combination of climatic factors, such as global warming, rainfall variation, flood, drought, temperature fluctuation, and salinity change. Considering the vulnerability of fish production to the impacts of climate change, tilapia farming is one of the possible strategies for adaptation to climate change. The positive culture attributes of tilapia are their tolerance to low water levels and poor water quality with rainfall variation, temperature fluctuation, and salinity change. In fact, tilapia farming is possible in a wide range of water environments, including freshwater, brackish water, and saltwater conditions. We suggest that appropriate tilapia culture strategies with institutional support and collaboration with key stakeholders are needed for adaptation to environmental change.

Abstract:

New and more efficient methods to sustainably intensify Aquaculture production are essential to attain the seafood demand for direct human consumption in the near future. Nutrition has been identified as one strategy of early exposure that might affect animal early development and later phenotype. This strategy may have positive consequences in the modulation of fish digestive physiology, which will correlate with higher performance outputs. Thus, improving fish digestive efficiency will lead to higher productivity and lower biogenic emission from aquaculture facilities, minimising the impact on the environment while increasing the biological efficiency. An innovative in ovo nutritional modulation technique based on low-frequency ultrasounds was used to enhance the transport of amino acids across the embryo membranes. An early stimulus with either arginine or glutamine, both involved in gut maturation, was applied in zebrafish (Danio rerio) embryos at 3.5 hours post-fertilization (hpf). At 22 days post-fertilization (dpf), growth performance, digestive enzyme activities and gut microbiota composition were analysed to evaluate the larval nutrition-induced metabolic plasticity and the effects on fish digestive efficiency. Results showed that fish survival was not affected either by the sonophoresis technique or amino acid supplementation. Final dry weight at 22 dpf was statistically higher in larvae from glutamine treatment when compared to the control even with lower trypsin activity, suggesting a higher nutrient digestion capacity, due to a slightly modulation of gut microbiota. Higher arginine supplementation levels should be tested as strategy to enhance growth at later developmental stages. In conclusion, this study demonstrated the efficiency of sonophoresis technique for in ovo nutritional modulation and suggests that in ovo glutamine supplementation might promote growth at later developmental stage through a positive microbiota modulation.
