Aquatic species enrichment refers to the practice of enhancing biodiversity and improving the genetic diversity of aquatic populations. In aquaculture, this can involve selective breeding, the introduction of new species, and the protection of natural habitats. Enrichment efforts aim to maintain a healthy gene pool, prevent inbreeding, and ensure sustainable population growth. It also involves enhancing the nutritional value of aquaculture products through the use of enriched feeds or habitat management practices that promote a more balanced ecosystem. Aquatic species enrichment supports the resilience of ecosystems and enhances productivity, both in wild and farmed fisheries. It plays a critical role in ensuring the long-term sustainability of aquaculture and the conservation of aquatic biodiversity.
