Description: Net pens are the most commonly used fish pens in the aquaculture industry. Nets are significantly cheaper than the alternatives, however nets give little protection from predators and expose the fish to toxins such as algae blooms. Bag pens are a new development. Bag pens provide a more solid separation between the fish and the environment. In this study is determined if the bacterial species, A. salmonicida and V. anguillarum, can colonize materials used by the aquaculture industry. Also is tested the bacteria’s ability to colonize on 2 types of fish pens: bags and nets and are tested the physical and chemical sterilization methods commonly used in the aquaculture industry and determined which is most effective.
