Technical Abstract: Disease occurs as a result of interactions between the fish, pathogens, and the environment. Disease outbreaks occur when a fish's resistance is lowered due to stress caused by environmental fluctuations or poor management practices. Therefore prevention requires minimizing environmental fluctuations and practicing good farm management practices. Despite careful and conscientious prevention, disease problems sometimes still occur. If a disease problem is identified it is important to correct all environmental or management stressors as quickly as possible, and prior to initiating treatment. Once stressors have been removed an appropriate treatment regime should be identified and initiated. There are two parts to an effective treatment, 1) the dosage or rate; and 2) and duration of treatment. The purpose of this chapter is to help farm managers calculate appropriate chemical dosages and treatment rates.
