Public hatcheries in the United States, including facilities culturing threatened and endangered fish, are severely restricted by the lack of legally approved medicinal drugs to treat diseased fish. Chloramine-T is a drug that has great potential to control and reduce mortalities associated with a number of external fish diseases.

Chloramine-T was identified by state and federal hatcheries as an urgently needed drug that will be used to reduce disease-related mortalities and improve production efficiency and product quality at public hatcheries. Studies required by the Food and Drug Administration were conducted to allow the approved use of chloramine-T to treat bacterial diseases on cold, cool, and warm water fish cultured in public hatcheries.
