Assessing Governability in Aquaculture Coastal Zones: New Insight from the International Level

Aquaculture Research, Journal Year: 2024, Volume and Issue: 2024(1)

Published: Jan. 1, 2024

Historically, European Union (EU27) member states have held sway over the administration of aquaculture sectors. However, challenges arisen within this regulatory framework, particularly concerning implementation sustainable conservation measures across EU27 region. In response to perceived shortcomings, alternative strategies like economic and community‐based management emerged. Thus, study aims investigate how global governance factors influenced growth industry (EU13) (EU14) from 1990 2023. To address endogeneity concerns, robust least squares, two‐stage squares (2SLS), ordinary estimators were employed, yielding significant findings. Notably, impact analysis reveals that property rights, stability, private sector quality, interest are pivotal drivers in EU14 developed countries compared their EU13 developing counterparts. Conversely, novelty paper shows growth, social development, advancement hold greater significance relative ones, as indicated by estimators. Given these insights, policymakers urged prioritize initiatives aimed at fortifying interest. encouraged focus on fostering enhancing public promoting development blue farming.

Genome-Assisted Gene-Flow Rescued Genetic Diversity Without Hindering Growth Performance in an Inbred Coho Salmon (Oncorhynchus kisutch) Population Selected for High Growth Phenotype

Marine Biotechnology, Journal Year: 2025, Volume and Issue: 27(1)

Published: Feb. 1, 2025

Abstract Selective breeding is a powerful tool for improving aquaculture production. A well-managed program essential, as populations can otherwise lose genetic diversity, leading to reduced selection response and inbreeding excesses. In such cases, diversity in broodstock must be restored by introducing individuals from external populations. However, this reduce the accumulated gains selective breeding. introduction of with superior phenotypes will allow restoration without sacrificing these gains. study, we demonstrated possibility using selectively bred (SB) randomly (RB) population coho salmon ( Oncorhynchus kisutch ). Forty males growth were selected RB genomic crossed 127 collected females SB population, producing newly (NB) population. Genetic assessed statistics effective number alleles, allele richness, observed heterozygosity 11 microsatellite markers, was higher NB than RB. Additionally, fork length body weight compared among three after 12 months post-fertilization common tanks. The least-squares means similar between (164.9 mm 57.9 g) (161.1 53.7 g), while both significantly greater (150.4 43.0 g). Our results highlight effectiveness genome-assisted gene flow restoring compromising gain growth.

Genetic assessment of farmed Oreochromis mossambicus populations in South Africa

PeerJ, Journal Year: 2025, Volume and Issue: 13, P. e18877 - e18877

Published: April 14, 2025

The global utilisation of Oreochromis spp. in freshwater aquaculture extends to South Africa. Here the native Mozambique tilapia ( mossambicus ) has been proposed as a priority species for regional projects, although it is still not preferred over non-native O. niloticus . There limited understanding genetic diversity, and differentiation farmed Using suite 14 microsatellite markers, present study aimed determine origin diversity four populations KwaZulu-Natal Mpumalanga provinces. Wild from rivers surrounding farms were included trace populations. Results revealed lower compared wild In particular, University Zululand population exhibited rest While most closely resembled their local counterparts, uMphafa ponds distinct characteristics. Notably, some individuals shared affinities with those Thukela River, suggesting that River could be source this population, or fish may have introduced escaped into river. suggests select potential use breeding broodstock supplementation programs but emphasizes importance thorough monitoring. However, before these can considered supplementation, further investigation required confirm integrity rule out contamination invasive species.

CRISPR-Cas9/Cas12a-based genome editing in Atlantic cod (Gadus morhua)

Aquaculture, Journal Year: 2023, Volume and Issue: 581, P. 740440 - 740440

Published: Dec. 5, 2023

Aquaculture is the fastest-growing food sector worldwide but faces sustainability challenges that need to be addressed in many ways, including genetic enhancement. Atlantic cod has re-emerged as an aquaculture species and tools for manipulation are needed. Thus, we compared five formats of CRISPR determine which was most efficient generate knock outs cod. Cas9 protein presented preformed ribonucleoprotein (RNP) complexes with single guide or duplex RNAs mRNA encoding used same two RNAs. Cas12a tested RNP We found RNA format out both alleles slc45a2 gene, resulted albino-like phenotype up 75% surviving larvae. DNA analysis individual larvae revealed mosaic genotypes variable indel mutations. The mortality injected eggs high, resulting low overall efficiency. Nevertheless, this study lays foundation further functional research using CRISPR/Cas9 genome editing system

Genomic architecture and sex chromosome systems of commercially important fish species in Asia – Current status, knowledge gaps and future prospects

Reviews in Aquaculture, Journal Year: 2024, Volume and Issue: 16(4), P. 1918 - 1946

Published: June 8, 2024

Abstract Aquaculture is one of the fastest growing agro‐food industries in world and Asia dominates world's fish production (70% total) with a high potential to ensure global food security. The leading aquaculture species show sexual dimorphism for traits such as growth, age at maturity etc. which sex outperforms other, increasing need controlling sex‐ratio farming system. Despite huge contribution Asian production, facing lot challenges, example, maintaining genetic purity balancing culture Many these difficulties arise due lack deep understanding genetics, or duplicated genome cultured species, unavailability high‐quality reference genomes information on determination mechanisms (crucial monosex establishing appropriate breeding programme). This review has described existing knowledge architecture four commercially important groups (carps, tilapias, catfishes snakeheads). We also have outlined possible strategies identifying sex‐determining gene/s using modern sequencing computational technologies. Finally, we highlighted challenges future prospects aquaculture. anticipate that developments technologies will help address biological complexities exist commercial be value growth industry Asia.
