The provision of safe and effective vaccination programs is one of the key tools to ensure the sustainable development of the aquaculture sector and therefore help meet growing global protein demands. In fact, aquaculture is widely regarded as one of the most important weapons against world hunger and malnutrition. The rapid growth of this sector continues to generate new challenges. Diseases are still a main issue, because they may generate extensive losses and result in a lack of investor confidence. Pathogens in commercial aquaculture have made it necessary for farmers to use veterinary medicines to treat disease outbreaks. Producing healthy farmed fish requires not only quality infrastructure and well-trained personnel, but also ensuring that the latest pharmaceutical technologies and state-of-the-art instrumentation and consumables are to the fore. Keeping the health and safety of humans and animals in mind, with no compromise to environmental commitments, is vital for reaching global sustainability goals.
