In September 1991 cataracts occurred in two year-classes of triploid Atlantic salmon. The fish showed varying degrees of blindness, were lethargic and became emaciated owing to their inability to feed. The lesions in the lens were mainly in the anterior and posterior cortex and perinuclear areas, the capsule and embryonic nucleus remaining unaffected. Diploid fish of the same year-class did not have cataracts. The origin of the triploid fish, the method of triploidisation, their diet and disease status were investigated, but no predisposing factors could be found to account for the high incidence of cataracts.
1991年9月，两个年龄组的三倍体大西洋鲑出现了白内障。这些鱼表现出不同程度的失明，行动迟缓，由于无法进食而变得消瘦。晶状体的病变主要位于前、后皮质和核周区域，晶状体囊膜和胚胎核未受影响。同年龄组的二倍体鱼没有患白内障。对三倍体鱼的来源、三倍体化方法、它们的饮食和疾病状况进行了调查，但未发现任何诱发因素可以解释白内障的高发病率。
