The world's fisheries play a critical role in global food security, livelihoods, and economies. As fishing practices have evolved over centuries, the integration of genetics into fisheries science has emerged as a powerful tool for understanding fish populations, managing stocks, and ensuring sustainable harvesting. In this comprehensive article, we will delve into the realm of fishery genetics, exploring its significance, applications, challenges, and contributions to the sustainable management of fisheries worldwide. Fishery genetics encompasses the study of genetic variation, heredity, and population structure within fish species. It involves applying genetic principles and techniques to understand the genetic diversity, population dynamics, and evolutionary processes of fish populations. Genetic research in fisheries is instrumental in assessing the health and resilience of fish stocks, identifying distinct populations, and guiding effective conservation and management strategies. Genetic diversity within fish populations is crucial for their adaptability, resilience, and long-term survival. It serves as the raw material for evolution, enabling species to respond to environmental changes, diseases, and other challenges.


This information is vital for sustainable fisheries management and setting appropriate harvest limits. DNA-based methods enable the authentication of fish species, traceability of fish products, and the detection of illegal fishing activities. This helps combat seafood fraud and ensures the legality and sustainability of fishery products. Genetic data assist in identifying endangered or vulnerable populations, facilitating targeted conservation efforts, and guiding the restoration of depleted stocks through breeding or stock enhancement programs. Genetic selection for disease resistance in aquaculture species is critical for reducing disease outbreaks and improving the overall productivity and sustainability of aquaculture practices. Advances in DNA sequencing technologies allow researchers to analyse the genetic composition of fish populations, identifying genetic markers for population differentiation, individual identification, and genetic diversity assessment. Microsatellites, repetitive DNA sequences, are commonly used as genetic markers for population studies, parentage analysis, and assessing genetic variability within fish populations. SNP markers provide high-resolution genetic data and are increasingly used in population genomics, genome-wide association studies, and marker-assisted breeding in aquaculture.


Obtaining representative and sufficient genetic samples from fish populations can be difficult, especially for migratory or deep-sea species, leading to potential biases in genetic assessments. Interpreting genetic data in the context of fisheries management requires interdisciplinary collaboration, integrating genetics with ecology, population dynamics, and socio-economic factors. Ethical considerations, including the impact of genetic interventions on wild populations, genetic manipulation, and the release of genetically modified organisms, require careful evaluation. Genetic studies have revealed distinct subpopulations of Atlantic cod, aiding in stock assessment and management strategies to prevent overfishing and preserve genetic diversity.
