Abstract
Abstract: A total of 33 cases of cataract found in cultured fishes were studied by the histologic method. The pathology of lens of a cataract in fingerling salmonids was characterized by regressive processes, abnormal proliferation and floating lens nucleus. This type of cataract may be classified as morganian cataract. The pathological changes in the lens tissues of worm cataract in young rainbow trout and of whitish conditions of the eye in yellowtails were briefly described.
