Applied genomics in aquaculture: Advances and potential



Aquaculture, as a fundamental pillar in marine food production, has undergone a silent revolution thanks to advances in applied genomics. This discipline has emerged as an invaluable tool for understanding, improving, and optimizing aquatic species in terms of reproduction, disease resistance, and performance.


What is applied genomics in aquaculture?

Applied genomics in aquaculture focuses on studying and analyzing the genome of aquatic species with the aim of applying that knowledge to enhance various aspects of their breeding and cultivation. This involves identifying genes associated with desirable traits, understanding genetic interactions, and selecting individuals with optimal genetic profiles.


Advances in reproduction: Beyond traditional selection

One of the major breakthroughs of applied genomics in aquaculture has been its impact on breeding programs. This not only accelerates the genetic improvement process but also allows the selection of individuals with optimal genetic profiles for reproduction, such as growth, feed efficiency, and meat quality. The identification of genetic markers associated with desirable traits has enabled more precise and rapid selection of breeders.

Featured projects:

  • Rainbow trout: Research on rainbow trout has used genomics to identify genes related to early sexual maturity. Applying this information to breeding programs has led to the development of trout lines that reach sexual maturity more efficiently.


Increasing resilience: Strengthening the health of aquatic populations

Applied genomics has opened new perspectives in understanding and managing the health of aquatic populations. Identifying genes associated with disease resistance enables the development of more robust and healthy breeding lines, reducing dependence on medical treatments and improving the sustainability of aquaculture.

Featured projects:

  • Vibrio-resistant oysters: Research on oysters has identified genes that confer resistance to Vibrio, a common pathogenic bacterium. Integrating this resistance into breeding programs has enhanced the health of oyster populations.


Improving performance: Optimizing aquaculture production

Applied genomics is also contributing to improving performance in terms of growth, feed efficiency, and product quality. Identifying genes related to these traits allows the development of breeding lines that maximize production without compromising quality.

Featured projects:

  • Fast-growing shrimp: Shrimp breeding programs have used genomics to identify genes linked to rapid growth. Implementing this selection has led to more abundant harvests in less time.


Future perspectives: Challenging the limits of genomic innovation

The potential of applied genomics in aquaculture seems limitless. Significant advances are expected in areas such as genetic editing to introduce specific traits, identification of genes linked to climate change adaptation, and the application of next-generation sequencing techniques for a deeper understanding of the aquatic genome.

Future projects:

  • Genetic editing in cultivated fish: Genetic editing research aims to develop cultivated fish with enhanced traits, such as increased disease resistance and accelerated growth.


Conclusions: Transforming aquaculture with applied genomics

In conclusion, applied genomics is playing a crucial role in the evolution of aquaculture, transforming how we breed and cultivate aquatic species. Advances in reproduction, increased resilience, and performance are driving efficiency, sustainability, and profitability in the industry. As we continue to explore the mysteries of the aquatic genome, we can anticipate an exciting era of genomic innovation that will shape the future of aquaculture significantly.
