The leading aquaculture fish species in Asia show sexual dimorphism for traits such as growth, age at sexual maturity etc. in which one sex outperforms the other, increasing the need for controlling sex-ratio in the farming system. Despite the huge contribution of Asian aquaculture to global fish production, the Asian aquaculture is facing a lot of challenges, for example, maintaining the genetic purity of the fish species and balancing the sex-ratio in the culture system. Many of these difficulties arise due to a lack of deep understanding of fish genetics, or to the duplicated genome of cultured species, or to the unavailability of high-quality reference genomes and information on sex determination mechanisms (crucial for monosex production and establishing appropriate breeding programme). This review has described the existing knowledge of the sex determination mechanisms in fish and genome architecture of four commercially important fish groups in Asia (carps, tilapias, catfishes and snakeheads). We also have outlined possible strategies for identifying sex-determining gene/s using modern genome sequencing and computational technologies. Finally, we have highlighted the existing challenges and future prospects of Asian aquaculture.

This article comprehensively reviews glycerol utilisation in fish and its potential as a dietary ingredient for aquaculture. While dietary inclusion of glycerol may offer cost-effective energy and metabolic intermediates, studies report inconsistent results regarding its effects on nutrient digestibility, zootechnical performance, and product quality. Recent studies however have demonstrated that dietary glycerol supplementation in fish induces metabolic shifts, such as alterations to gluconeogenesis and/or lipogenesis, modifying energy utilisation. Additionally, glycerol has been proposed to reduce protein catabolism, minimising nitrogen excretion and its environmental impact, but its influence on protein retention remains uncertain. Nevertheless, it is important to carefully consider the balance between feed palatability and these potential metabolic alterations when incorporating glycerol in aquafeeds. This review highlights the need for more studies to expand our understanding of glycerol metabolism in fish, since it does not seem to be metabolised by carnivorous species as much as omnivorous. Future research should explore the effects of glycerol supplementation on fish with different feeding habits and in developmental stages, as well as diverse environmental salinities and temperatures. Insight into the impact of impurities and the optimisation of glycerol inclusion in aquafeeds are recommended to support sustainable aquaculture practices and the utilisation of glycerol as a valuable resource.</p>","PeriodicalId":227,"journal":{"name":"Reviews in Aquaculture","volume":"16 4","pages":"1901-1917"},"PeriodicalIF":8.8,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/raq.12930","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141299133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stakeholder groups perceived aquaculture differently and depending on the circumstances and context, their perceptions ranged from positive to negative. Many factors influenced their perceptions, including aquaculture's impact on multiple sustainability dimensions, knowledge, transparency, personal interests, types, and location of aquaculture practises, regulations, experience, and sociodemographic characteristics such as age, gender, education, and income.

In the last decades, its intensification has increased the incidence of viral and bacterial infections, emphasizing the need for novel disease management strategies. <i>Vibrionaceae</i> bacteria are widespread in aquatic environments, affecting various host species, including economically important fish, shrimp and bivalves. Also, human consumption of undercooked aquatic food contaminated with <i>Vibrionaceae</i> and/or their toxins poses a threat to human health, leading to conditions such as gastroenteritis, wound infection and sepsis. In addition, small fish and shrimp, in open aquaculture systems, can be eaten by birds that can then carry and spread this pathogen to livestock and humans. Many <i>Vibrionaceae</i> produce toxins, some detrimental or even lethal to the hosts, others affecting surrounding bacteria. This review provides a comprehensive overview of <i>Vibrio</i> toxins affecting aquatic (in)vertebrate, summarizing findings on molecular structures, mechanisms of action and regulation and secretion processes involved. Important toxin classes for microbe–host interactions, such as haemolytic, proteolytic and MARTX toxins, are discussed, along with other toxins like PirAB produced by the AHPND-causing <i>Vibrio parahaemolyticus</i>.

Decapod crustaceans display either female heterogamety (ZW/ZZ) or male heterogamety (XY/XX) as their mode of genotypic sex determination. However, some decapod species exhibit sexual plasticity via removing the androgenic gland, knockdown insulin receptor transcripts, administrating exogenous sex steroids, and altering environmental factors. Although the master sex-determining gene in decapods remains elusive, various sexual genes, hormones, and neurotransmitter are emerging as important factors in sex differentiation. This review looks into recent advancements in studies related to the genetic sex determination system and factors that trigger sex reversal. Moreover, the elucidation of the role of genetic factors in sex differentiation in both females and males, as well as their underlying interrelated regulatory mechanisms, provides justification for three levels of application: the induction of monosex populations, detection of precocious sex and genotype, and prevention of uncontrolled reproduction. Finally, we proposed future directions of bioinformatics analysis and genome editing coupled with sex control to increase the yield for economic decapods.

The occurrence of bacterial strains/biofilms with more resistance to different preventive strategies is a big challenge for the seafood processing industry. This review covers the mechanisms of biofilm formation by bacteria and various non-thermal processing approaches to prevent microbial contamination and biofilm formation in seafood products. The aforementioned non-thermal processing techniques for the destruction of biofilm and quality control of seafood products include cold plasma treatment, irradiation, pulsed electric field technology, hydrostatic pressure processing, photosensitisation, natural bioactive compounds and so on.
