As the aquaculture industry expands, new considerations emerge throughout the farmed seafood production cycle. Animal health and welfare is an important aspect of aquaculture, and it is heavily influenced by environmental factors as well as the fundamentals of the industry. Fish welfare is essential to all elements of fish management and has a significant impact on the health, survival, productivity, and quality of the final product. From the egg through the final harvest, every management practise we impose on our fish stocks will have an impact on the fish's wellbeing by causing stress or even harm. New technology has enabled breeders to have a better understanding of their livestock' health and, as a result, better care for them. Aquatic animal health measures are critical for ensuring the long-term viability of production systems. Veterinarians, aquatic animal health specialists, and other stakeholders are critical in ensuring that aquatic animals' health and welfare are not jeopardized, and that aquatic animal products are safe for human consumption and correctly certified to meet international trade regulations.
