Abstract
As discussed in previous chapters, maintaining a fish—pathogen-environment relationship that is favorable to the fish is critical to the continuing success of any hatchery, fish farm, or aquaculture facility. The most important method of achieving the required favorable relationship is to manage the interactions of fish with biological, chemical, and physical conditions in the rearing environment so as to minimize the effects of stress on resistance to infectious and noninfectious diseases. In some cases, however, it is practical to improve the fish—pathogen-environment relationship by reducing or eliminating the pathogen load of the water supply as well. At present, the most promising approaches are quarantine, brood-stock segregation, and other biological control methods that exclude pathogens from the hatchery facility initially; and water treatment systems using ultraviolet light (UV), chlorine, or ozone as disinfectants.
