Plant-based lipids are a viable alternative to forage fish ingredients in finfish diets. However, most plant-derived lipids lack long-chain polyunsaturated fatty acids (LC-PUFA) like EPA and DHA, which are nutritionally essential for fish. This review summarizes recent findings on the nutritional aspects of fish brood stock and sperm quality, emphasizing the effects of fatty acids on reproductive outcomes. Studies indicate that substituting fish oil with plant oils alters the fatty acid profiles in fish tissues and gametes, potentially compromising sperm quality, cryopreservation success, and progeny viability. Sperm membrane lipids, including EPA, DHA, and ARA, are vital for motility and fertilization rates post-thaw. Additionally, cryopreservation has been linked to molecular and epigenetic alterations in sperm, which may negatively affect offspring quality. The role of mRNA and noncoding RNA in regulating sperm function and embryonic development is well known, and thus any damage to these molecules as a consequence of cryopreservation might induce long-term effects on offspring. Proteomic analyses reveal that cryopreservation can lead to significant protein loss in sperm, diminishing their functional and fertilization capabilities. Optimizing cryoprotectant protocols and freezing techniques is crucial to reduce damage, while dietary fatty acids play a key role in preserving sperm quality during cryopreservation stress. Further research with omic technologies is crucial to fully understand sperm tolerance to cryopreservation, which will improve reproductive outcomes and enhance sustainability and quality in aquaculture.</p>\u0000 </div>","PeriodicalId":227,"journal":{"name":"Reviews in Aquaculture","volume":"17 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142398528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Continued production depends on preventing and controlling diseases and parasites. A critical part of the farmed salmon's life is during smolt production and the following well-boat transport out to sea. Biosafety here is thus essential, and there is a need for an overview of risk factors and measures. Biosafety is related to the technical solutions' design, construction, cleaning, and maintenance, that can be studied through field work, interviews, and document analysis. This paper presents results from a study identifying risk factors related to technical solutions in smolt production (with RAS—recirculating aquaculture systems) and well-boats, and potential measures to reduce risk. Risk factors for RAS facilities are divided into four main groups: Introduction of pathogens to the facility, spread of pathogens inside the facility, growth of pathogens inside the facility, and additional risks. Risk factors for well-boats are divided into three main groups: Introduction of pathogens through intake water, spread of pathogens between fish groups, and spread of pathogens from well-boat to the environment. Measures are proposed to mitigate the identified risk factors. The lists are not exhaustive, and risk magnitude is not quantified, so effect of measures is not calculated.

Out of the 42 studies identified, 132 emerging contaminants were observed. The Southeast and South regions accounted for most of these studies, with limited research conducted in the North and Northeast regions. Tilapia was the most studied species, followed by mollusks. In toxicity tests, animals showed several effects, such as decreased oxygen consumption and swimming patterns, histopathological changes, inhibition of sperm production, cardiac edema, spinal deformity, and antimicrobial resistance. In conclusion, advancements in research on emerging contaminants in Brazilian aquaculture are needed as the number of existing studies is lower compared to global numbers. Few studies have focused on analyzing cultivation sites to identify the contaminants present and their sources. Also noteworthy is the scarcity of work in the Northern region of Brazil and on native species. Characterizing these environments in terms of the types of contaminants and main sources of contamination is essential to finding ways to mitigate ecological and human health risks, as well as developing specific legislation for these contaminants because they are currently not part of routine monitoring programs and are therefore not regulated, especially in aquaculture environments.</p>\u0000 </div>","PeriodicalId":227,"journal":{"name":"Reviews in Aquaculture","volume":"17 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142363110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Immune priming is a phenomenon that invertebrates mount a faster and stronger secondary response than that of the primary response when encountered with a given microbe. It has been demonstrated to be present in a wide range of aquaculture species and would provide a fresh idea for disease prevention. As the main executors of immune defense in invertebrates, the circulating hemocytes are short-lived, and the solution for the paradox of keeping a long-lasting immune protection might lie in the formation of long-lived memory cells in immune priming. As a reference for the access of memory cell formation processes in aquaculture invertebrates, the cellular kinetics including expansion, contraction, and memory formation of lymphocytes in the adaptive immunity of vertebrates are discussed. Then the features of hemocytes in aquaculture invertebrates, and their kinetic changes of cell number and immune capacity during immune priming are summarized for the knowledge of a stronger secondary immune response. The regulatory roles of epigenetic modification and metabolic reprogramming in immune priming and their possible functions in memory cell formation and identification are proposed to be preferentially investigated for further clarifying the mechanism of immune priming, which might provide a novel entrance for understanding the mechanisms of immune priming and developing disease prevention strategy in aquaculture invertebrates.</p>\u0000 </div>","PeriodicalId":227,"journal":{"name":"Reviews in Aquaculture","volume":"17 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142321866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It holds significant potential as an alternative ingredient in aquaculture feed due to its relatively high crude protein content, balanced amino acid profile, and presence of bioactive compounds. However, one of the main challenges with shrimp processing waste is its rapid spoilage. Consequently, shrimp solid processing waste must undergo further refinement to produce shrimp-derived products suitable as aquaculture feed ingredients, such as meal, hydrolysate, or silage. This literature review describes the nutritional value, applications, challenges, and prospects of these shrimp-derived products in aquaculture feed. Among the investigated shrimp-derived products, shrimp hydrolysate has the highest nutritional value considering the high crude protein content, balanced amino acid profile, low chitin content, and low ash content. However, producing shrimp hydrolysate requires extensive processing, which can be costly, limiting its applications to high-value aquaculture species. On the other hand, shrimp meal and shrimp silage, which require less energy-intensive processing, may be more suitable for lower-value aquaculture species that naturally consume feeds high in ash and chitin. The prospects for using shrimp-derived products in aquafeed are promising, with advances in processing technologies showing potential to reduce costs, improve nutritional value, and enhance product quality and safety.
