I am studying for a biotechnology test (which is tomorrow :o ) and I have found an interesting journal article review on probiotics for fish. This involves the addition of bacteria to the water and/or food.
It has been shown that the addition of certain bacteria to the water prevents other strains from adhering to the eggs, thereby increasing the chance that the eggs are successful. The addition of certain bacteria to the food has also been shown to increase the immune system of certain fish, which results in the increase in survival of fry as well as adult fish. Even the addition of certain bacteria to the water increases their immune system.
It will be interesting to watch the new products being released on the market. They may be more biologically based than chemically based.
It may also suggest that keeping the water as sterile as possible is not the best method, as an amount of a certain bacteria is desirable.
The article is Verschuere et. al. 2000. Probiotic Bacteria as Control Agents in Aquaculture. Microbiology and Molecular Biology Reviews. Vol 64 no 4:655-671
