Fish biology has been developed for more than 100 years, but some important breakthroughs have made in the last decade. Early studies commonly concentrated on morphology, phylogenetics, development, growth, reproduction manipulation, and disease control. Recent mostly focused genetics, molecular biology, genomics, genome biotechnologies, which provided a solid foundation enhancing aquaculture to ensure food security improving aquatic environments sustain ecosystem health. Here, we review research advances five major areas: (1) biological innovations genomic evolution of four significant fish lineages including non-teleost ray-finned fishes, northern hemisphere sticklebacks, East African cichlid Asian cyprinid fishes; (2) evolutionary fates consequences natural polyploid (3) domestication selection; (4) development innovation breeding biotechnologies; (5) applicable approaches potential genetic biotechnologies. Moreover, precision biotechniques are examined discussed detail gene editing introgression or removal beneficial detrimental alleles, use sex-specific markers production mono-sex populations, controllable primordial germ cell on-off strategy producing sterile offspring, surrogate broodstock-based strategies accelerate breeding, incorporation sexual regain-based approach create synthetic polyploids. Based these scientific technological advances, propose blueprint improvement new breed creation species analyze seed industry strengthening security.

Genome‐wide association and genomic selection in aquaculture

Reviews in Aquaculture, Год журнала: 2022, Номер 15(2), С. 645 - 675

Опубликована: Ноя. 17, 2022

Abstract Recent advancements in genomic technologies have led to the discovery and application of DNA‐markers [e.g. single nucleotide polymorphisms (SNPs)] for genetic improvement several aquaculture species. The identification specific regions associated with economically important traits, using, example, genome‐wide association studies (GWAS), has allowed incorporation markers linked quantitative trait loci (QTL) into breeding programs through marker‐assisted selection (MAS). However, most traits economic relevance are expected be controlled by many QTLs, each one explaining only a small proportion variation. For under polygenic control, prediction merit animals based on sum effects at positions across entire genome (i.e. estimated values, GEBV, which used what become known as selection), been demonstrated speed rate gain breeding. aim this review was provide an overview development uncovering basis complex accelerating progress species, well providing future perspectives about deployment novel molecular selective coming years.

Abstract Since its introduction in 2001, genomic selection (GS) has progressed rapidly. As a research and application hot topic, GS led to revolution the field of animal plant breeding. Thanks ability overcome shortcomings traditional breeding methods, garnered increasing attention. Both theoretical practical studies have revealed higher accuracy than that breeding, which can accelerate genetic gain. In recent years, many been conducted on aquaculture species, shown produces prediction pedigree‐based method. The present study reviews principles processes, preconditions, advantages, analytical methods factors influencing as well progress into these aspects. Furthermore, future directions are also discussed, should expand more species.

Sustainable use of CRISPR/Cas in fish aquaculture: the biosafety perspective

Transgenic Research, Год журнала: 2021, Номер 31(1), С. 1 - 21

Опубликована: Июль 25, 2021

Abstract Aquaculture is becoming the primary source of seafood for human diets, and farmed fish aquaculture one its fastest growing sectors. The industry currently faces several challenges including infectious parasitic diseases, reduced viability, fertility reduction, slow growth, escapee environmental pollution. commercialization growth-enhanced AquAdvantage salmon CRISPR/Cas9-developed tilapia ( Oreochromis niloticus ) proffers genetic engineering genome editing tools, e.g. CRISPR/Cas, as potential solutions to these challenges. Future traits being developed in different species include disease resistance, sterility, enhanced growth. Despite notable advances, off-target effect non-clarification trait-related genes among other technical hinder full realization CRISPR/Cas potentials breeding. In addition, current regulatory risk assessment frameworks are not fit-for purpose regarding notwithstanding that public acceptance key products new technology. this study, we discuss how can be used overcome some limitations focusing on diseases release aquaculture. We further present limitations, use proffer research strategies will provide much-needed data decisions, assessments, increased awareness sustainable applications with emphasis Atlantic Salmo salar

Abstract Mass mortality events (MMEs) are defined as the death of large numbers fish over a short period time. These can result in catastrophic losses to Atlantic salmon aquaculture industry and local economy. However, they challenging understand because their relative infrequency high number potential factors involved. As result, causes consequences MMEs not well understood. In this study, we developed structural network causal risk for communities that depend on aquaculture. Using Interpretive Structural Modeling (ISM) technique, analysed mass mortalities due environmental (abiotic), biological (biotic) nutritional factors. The were also assessed occupational health safety workers implications livelihoods communities. This deepens our understanding points management actions interventions help mitigate mortalities. typically single factor but caused by systematic interaction related environment, diseases, feeding/nutrition cage‐site management. Results indicate considerations risk, through pre‐ post‐event assessments, may minimize workplace injuries eliminate risks human fatalities. Company government‐assisted socio‐economic measures could post‐mass impacts. Appropriate timely reduce at cage sites physical social vulnerabilities
