Between 1977 and 1981, the Fish Pathology Laboratory of the Ontario Veterinary College received 239 cases from trout farms of southern Ontario, 51 (21.3%) of which had diseased gills. Branchial lesions in 86.3% of these 51 cases were characterized by marked lamellar epithelial hyperplasia with epithelial hypertrophy and lamellar fusion. Filamentous bacteria were seen on the surface of the branchial filaments and lamellae in 68.6% of the cases. Our observations highlight the importance of gill diseases as a production problem of farmed salmonids in southern Ontario.

1977年至1981年间，安大略兽医学院鱼类病理学实验室收到了来自安大略省南部鳟鱼养殖场的239个病例，其中51例（21.3%）有鳃部病变。这51例病例中，86.3%的鳃部病变特征为显著的鳃小片上皮增生，伴有上皮肥大和鳃小片融合。68.6%的病例在鳃丝和鳃小片表面可见丝状细菌。我们的观察结果凸显了鳃部疾病作为安大略省南部养殖鲑科鱼类生产问题的重要性。
