Published: Nov. 1, 2019

Approximately 70% of the aquatic-based production animals is fed aquaculture, whereby are provided with high-protein aquafeeds. Currently, aquafeeds reliant on fish meal and oil sourced from wild-captured forage fish. However, increasing use unsustainable and, because an additional 37.4 million tons will be required by 2025, alternative protein sources needed. Beyond plant-based ingredients, fishery aquaculture byproducts insect meals have greatest potential to supply over next 10–20 years. Food waste also has through biotransformation and/or bioconversion raw materials, whereas microbial macroalgal biomass limitations regarding their scalability content, respectively. In this review, we describe considerable scope for improved efficiency in discuss development optimization ensure a socially environmentally sustainable future industry.

The role of the gut microbiome in sustainable teleost aquaculture

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2020, Volume and Issue: 287(1926)

Published: May 6, 2020

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

Aquaculture is the fastest growing food production sector and rapidly becoming primary source of seafood for human diets. Selective breeding programs are enabling genetic improvement traits, such as disease resistance, but progress limited by heritability trait generation interval species. New technologies, genome editing using CRISPR/Cas9 have potential to expedite sustainable in aquaculture. Genome can introduce favorable changes genome, fixing alleles at existing loci, creating de novo alleles, or introducing from other strains The high fecundity external fertilization most aquaculture species facilitate research application a scale that not possible farmed terrestrial animals.

An overview of disruptive technologies for aquaculture

Aquaculture and Fisheries, Journal Year: 2021, Volume and Issue: 7(2), P. 111 - 120

Published: June 11, 2021

The world wild fish stocks are being depleted in an ever-increasing speed. Aquaculture is the only way to ensure sufficient seafood for world. Conventional aquaculture can be traced back 4000 years China and has been very successful past three decades. However, faced serious challenges, including a few improved species, labour-intensiveness, environmental pollution, diseases lack of traceability products. needs disruptive technologies increase production. Novel technologies, genome editing, artificial intelligence, offshore farming, recirculating systems, alternative proteins oils replace meals oils, oral vaccination, blockchain marketing internet things, may provide solutions sustainable profitable aquaculture.

Genomic Prediction Using Low Density Marker Panels in Aquaculture: Performance Across Species, Traits, and Genotyping Platforms

Frontiers in Genetics, Journal Year: 2020, Volume and Issue: 11

Genomic selection increases the rate of genetic gain in breeding programs, which results significant cumulative improvements commercially important traits such as disease resistance. currently relies on collecting genome-wide genotype data accross a large number individuals, requires substantial economic investment. However, global aquaculture production predominantly occurs small and medium sized enterprises for whom this technology can be prohibitively expensive. For genomic to benefit these sectors, more cost-efficient genotyping is necessary. In study utility low density SNP panels (ranging from 100 9,000 SNPs) accurately predict values was tested compared four datasets with different characteristics (species, genome size, platform, family total population target trait). The show heritabilities between 0.19-0.49, prediction accuracies using full panel 0.55-0.87. A consistent pattern accuracy observed across species little or no reduction until reduced below 1,000 SNPs (prediction 0.44-0.75). Below density, heritability estimates tended lower variable (93% maximum achieved SNPs, 89% 500 70% SNPs). notable drop 200 (0.44-0.75) (0.39-0.66). Now that multitude studies have highlighted benefits over pedigree-based species, current highlight at densities cost, raising possibility broader application improvement smaller fragmented settings.
