Studies on preventing diseases of cage-reared rainbow trout (Salmo gairdneri Rich.) in lakes

Abstract

Juvenile rainbow trout, Salmo gairdneri Rich., kept in cages in lakes showed better health and survival after some preventing procedures had been applied in order to improve living conditions of fishes and counteract the spread of mass diseases. With this purpose in mind, cages were fed with lacustrine deep waters and various medicated baths were applied.
