Vaccination in aquaculture refers to protecting fish from common diseases by giving them preventive treatments, similar to how humans get vaccines. It's a crucial practice in fish farming that helps keep fish populations healthy and reduces the need for antibiotics. Fish farmers and aquaculture technicians use vaccination to prevent disease outbreaks that could harm fish stocks and impact production. This process requires specific skills in handling fish and administering vaccines correctly, often done by trained staff who understand fish health management.
