Innovations in aquaculture reproduction focus on improving the breeding and spawning of farmed fish to enhance production efficiency and sustainability. Techniques such as selective breeding, genetic modification, and induced spawning have revolutionized the industry. Selective breeding is used to develop fish with desirable traits, such as faster growth or disease resistance. Hormonal treatments and controlled environmental conditions are employed to induce spawning, ensuring year-round breeding cycles and higher yields. Genetic advancements also help in producing sterile fish populations, reducing the risk of invasive species in wild ecosystems. These innovations are essential in meeting the growing demand for seafood while minimizing the impact on natural fish stocks, allowing for more sustainable and controlled fish farming practices.
