Abstract Lipidomics is a research area that investigates lipidomes that refer to the complete lipid profile within a cell, tissue, organism, or ecosystem by focusing on the interactions with neighboring molecules at the inter- or intracellular spaces of organisms. In recent decades, lipidomics has greatly evolved along with developments in mass spectrometric analysis (i.e., ionization approaches, the types of analyzers, and the data processing tools), leading to a rapid and accurate performance in the identification and quantification of individual lipid species. In this contribution, the identification and quantification of triacylglycerol (TAG) and phospholipid (PL) species in marine sources using mass spectrometry analysis are comprehensively discussed along with their physiological roles and health-beneficial effects on the human body. Moreover, this review emphasizes the importance of the isotopic deconvolution and instrument responses caused by the difference in the carbon number and the unsaturation of TAG and PL species in quantitative analysis. Most TAG and PL detected in marine taxa possess a high proportion of polyunsaturated ω3 long-chain polyunsaturated fatty acids (LCPUFA, ≥C20) in particular eicosapentaenoic acid (EPA, 20:5ω3) and docosahexaenoic acid (DHA, 22:6ω3), indicating the large number and structural diversity of glycerolipid species containing EPA and DHA. This review also discusses the health effects of TAG and PL species esterified with ω3 LCPUFA. Given that most fisheries science and aquaculture research during recent decades has mainly focused on ω3 LCPUFA after release from parent molecules, discussion of the health effects of ω3 LCPUFA in the form of TAG and PL extends understanding of the bioactivities of ω3 fatty acids as they occur naturally.

Abstract Aquaculture has grown rapidly to play a crucial economic and social role and meet the increasing global demand for seafood. As aquaculture intensifies, there is increasing pressure to find more sustainable practices that save resources and reduce waste. Major wastes and by-products from aquaculture were quantified across a full range of farming types. Key opportunities for wastewater treatment and by-product recovery include nutrient recycling through a combination of biofilters, bioaccumulation and multitrophic systems. To support a sustainable intensification of aquaculture, improvements in by-product harvesting, accumulation and processing methods require further investigation. Likewise, energy generated from by-products can potentially support intensified production through land-based recirculating aquaculture systems (RAS). Future challenges faced by the reuse of side streams include control of food safety and gaining consumer acceptance. Combined with increases in resource use efficiency across the aquaculture sector, from feeding methodologies to product storage, nutrient recycling can enable aquaculture to contribute sustainably toward the nutritional requirements of billions of people over the next century.

Abstract Aquaponics is the integration of aquaculture and hydroponics where nutrients released by growing fish are utilized by plants grown in a soilless culture, often in a controlled environment. Potential advantages of aquaponics include improved sustainability, reduced resource consumption, and fewer environmental impacts compared to conventional aquaculture. Based on a 2014 survey, it was found that most respondents were practicing aquaponics as a hobby. Other groups of respondents were educators, non-profit organizations that operate aquaponic systems, commercial operators, and consultants that sell goods, material, and services. Although many proponents cite the opportunity to create a commercially viable food production system few (if any) ventures have demonstrated sustainable financial outcomes. In general, much of the peer-reviewed aquaponic publications and popular literature, and despite the efforts of some investigators, lacks a methodical scientific basis for describing the essential mechanics, relationships, and culture methods within aquaponic systems. Many systems evolved from small-scale experimental facilities devised by trial and error methods and were implemented with locally limited appropriate species, limited finances, and distorted market situations. Many of the published aquaponic experiments are based on small systems, short growth trials, and weak experimental design. The predominant system design approach is based on a relatively small number of experiments. This review introduces notation and algorithms that are intended to standardize the numerous critical values essential in aquaponics for purposes of determining design criteria and operational parameters including flows, the concentration of water quality constituents, metabolite production, and productivity of plant and animal segments in an aquaponic systems. The objective of this systematic approach is to employ scientific methods that provide research results that can be replicated, challenged, and improved. This methodology is expected to facilitate more rapid development of scientific information, productive systems, and rational economic applications. This approach is crucial for commercial applications where production cost, product value, and investment returns are of critical importance for practitioners that envision investment in new ventures. For hobbyists and educators, economic issues may not be as important as the self-sufficiency and natural synergism aspects, personal satisfaction, and the learning experience that result from existing state-of-the-art of aquaponic practices. These outcomes remain for all and a clearer understanding of smaller personal systems is likely to be enhanced.

Abstract Whilst the aquaculture sector continues to grow and make an ever increasing contribution to world food supplies, there is a need to ensure that the sector continues to develop in a socially, economically and environmentally sustainable manner, in line with the United Nations sustainable development goals. The present paper focusses on the major perceived sustainability issues related to feed inputs for finfish and crustacean aquaculture species, including sustainability issues related to feed formulation and ingredient selection, feed manufacture and feed quality, on-farm feed use and impacts, and fish quality and food safety.

Abstract Management Strategy Evaluation (MSE) is a framework to explore the tradeoffs amongst fishing strategies and assess the consequences for achieving management goals provided sources of uncertainty by means of simulation models (referred to as operating models). Single-species stock assessment often implements simulations for MSE, but the operating models often omit the dynamics of key biological interactions. This could be a disadvantage for the evaluation of tradeoffs as species interactions could have an impact on the performance of harvesting strategies. Tools for conducting ecosystem-based fisheries management (EBFM), such as integrated ecosystem assessments, include executing MSEs with ecosystem models, many of which explicitly include biological interactions. Although the support for EBFM has grown over the years, the amount of information provided by MSEs based on ecosystem models appears to be limited. A clear summary of such efforts would provide beneficial information for future efforts for EBFM. Herein, an inventory of applications simulating MSEs with ecosystem models that explicitly include biological interactions was developed based on findings from a literature review. First, the methodologies and foci across all identified applications are analyzed. Next, summaries of each application are provided. Lastly, general observations are provided along with recommendations for future applications.

Abstract The rapid, global spread of COVID-19, and the measures intended to limit or slow its propagation, are having major impacts on diverse sectors of society. Notably, these impacts are occurring in the context of other anthropogenic-driven threats including global climate change. Both anthropogenic stressors and the COVID-19 pandemic represent significant economic challenges to aquaculture systems across the globe, threatening the supply chain of one of the most important sources of animal protein, with potential disproportionate impacts on vulnerable communities. A web survey was conducted in 47 countries in the midst of the COVID-19 pandemic to assess how aquaculture activities have been affected by the pandemic, and to explore how these impacts compare to those from climate change. A positive correlation between the effects of the two categories of drivers was detected, but analysis suggests that the pandemic and the anthropogenic stressors affect different parts of the supply chain. The immediate measurable reported losses varied with aquaculture typology (land vs. marine, and intensive vs. extensive). A comparably lower impact on farmers reporting the use of integrated multitrophic aquaculture (IMTA) methods suggests that IMTA might enhance resilience to multiple stressors by providing different market options under the COVID-19 pandemic. Results emphasize the importance of assessing detrimental effects of COVID-19 under a multiple stressor lens, focusing on areas that have already locally experienced economic loss due to anthropogenic stressors in the last decade. Holistic policies that simultaneously address other ongoing anthropogenic stressors, rather than focusing solely on the acute impacts of COVID-19, are needed to maximize the long-term resilience of the aquaculture sector.

Abstract Systematic review and meta-analysis (MA) were performed to summarize scientific evidence of the effects of cryopreservation of sperm from South American species of freshwater fish using the motility rate as an indicator. The search strategy was applied to four electronic databases, and the inclusion criteria were studies conducted on neotropical fish, including semen, that were submitted to cryopreservation. Meta-analysis for random effects was performed for each indicator according to the general average of fresh (control) and cryopreserved (treated) semen. A total of 25 publications reporting 26 studies and 116 trials were included in the MA. Heterogeneity was observed between studies for all variables. In general, cryopreserved semen showed lower advanced motility, an increase of which was observed (P < 0.01) in a greater proportion of semen dilution. Results showed that cryopreservation with the use of cryoprotectants such as alcohols and amides seem to favor the motility rates of the cryopreserved semen of neotropical South American freshwater species.

Abstract Elemental profiling is a process where element concentrations in tissues are used to discern group membership between a priori groups, such as geographic location. The goal of this meta-analysis was to determine the effectiveness of elemental profiling to discern the geographic origin of seafood products when coupled with discriminant analyses. Cohen’s Kappa of discriminant analyses were calculated based on reported accuracies and calculated expected accuracies. A systemic literature review was conducted which generated 86 effect sizes from 43 studies. A random effects model was used to estimate Cohen’s Kappa, and the average effect observed was 0.83 (±0.036 95% CI) with a p value of <0.001. Moderators were investigated as part of this analysis. There were no significant differences based on production method or geographic range, but differences were observed based on the type of tissue analyzed and taxa groups. Meta-regression was used to analyze the relationship between the effect size and the number of elements included in each analysis or sample size. There was no observed relationship between Kappa and the number of elements analyzed or the sample size of the study. Based on these results, recommendations for future studies that utilize elemental profiling are included.

Abstract The demand for caviar has increased in recent years because of its high nutritional and commercial values. Consequently, the wild population of sturgeon has decreased. This has shifted the balance of supply of caviar from wild sturgeon to more from farmed fish. The development of aquaculture has resulted in many technical advances of sturgeon rearing. The same factors that encouraged sturgeon farming have also stimulated the search for alternative products optimizing wild-sourced caviar utilization and even created some new market opportunities. Caviar substitutes have been obtained from at least 38 fish species (other than sturgeon) and aquatic animals, e.g., sea urchin, sea cucumber and snails. Although, the emergence of products has not always been positive, as the sturgeon caviar market has been impacted by commercial mimicry, fraud, and mislabeling of caviar-substitutes. This review provides information about the global production and trade of sturgeon, caviar, and caviar substitutes. In addition, the physics, gastronomy, and the quality changes of caviar and caviar substitutes during different fish-harvesting steps are discussed. Moreover, information about commercial mimicry, fraud, and new methods to detect these criminal acts are considered.

Abstract Migration timing has evolved in many animals, allowing them to maximize breeding and feeding success by matching seasonal changes in abiotic conditions and resource pulses. These seasonal changes can shift with the climate, resulting in mismatches between migrations and resource availability unless the populations respond through phenotypic plasticity or evolutionary adaptation. It is common, however, for factors unrelated to climate to affect phenology. Salmon are an exceptionally well-studied group of fishes whose breeding migrations can serve as a template to consider the complex factors affecting migration phenology. In this paper, hypotheses for explaining changes in adult salmon migration phenology are reviewed. Pathways through which climate change may influence migration timing are first summarized, including shifting migration cues, limiting freshwater conditions, changes in distribution and conditions at sea, and alterations in embryo development. Alternative causes of phenological change in salmon are then explored including anthropogenic modifications of river habitat, demographic effects, hatcheries, and fisheries. The effects of these factors on phenology can mimic and mask climate effects, making it challenging to disentangle the causal basis of observed patterns. Instead of inferring shifts from trends in timing data (as is often done), it is suggested that specific mechanistic hypotheses be proposed and tested rigorously, and alternative causes systematically ruled out. Overall, it is challenging to attribute causation to phenological change, but salmon exemplify the many ways in which migration timing can change, including shifts due to climate and other processes.
