Biosecurity: Protecting Farmed Fish

What is Biosecurity?

Biosecurity is the process of taking precautions to minimize the risk of introduction and spread of infectious organisms into or between populations.

Why is Biosecurity so important?

Biosecurity is very important to aquaculture because it prevents or limits the introduction and spread of disease within or between aquatic animal production facilities and sites. Since very few effective treatments are available for most aquatic animal diseases, effective biosecurity is the key to preventing these diseases.

How are infectious organisms transmitted?

Disease agents that infect aquatic animals are frequently spread between aquatic organisms in the environment, or equipment used to transfer animals from one holding unit or site to another. Some diseases can also be spread directly through the water by animals releasing the infectious agent or by sick animals dying. Known sources of aquatic animal infections include contaminated feed, equipment, untreated wastewater, fish bearing source waters, and pests such as birds or rodents.

What can I do to reduce the risk of disease introduction or spread?

How do I keep the aquatic animals in my facility healthy?
