Ocular abnormalities occurring in farmed halibut at the Sea Fish Industry Authority Marine Farming Unit, Ardtoe, Argyll were investigated clinically and post mortem. A significant number of fish were found to have posterior polar cystic changes either causing scleral ectasia or gross degenerative posterior segment abnormalities with chorioretinal atrophy. Other ocular abnormalities included cataract formation and intraocular inflammation. In a small number of fish gas bubble formation in the anterior chamber was observed during capture and examination. It is possible that the lesions seen in these fish are a form of gas bubble disease although super-saturation, the cause of gas bubble disease previously reported in farmed fish, does not occur in the tanks in which these fish are housed. While this paper provides no answers with regard to the aetiopathogenesis of the lesions, it is hoped that it will stimulate discussion, leading to resolution of these questions through a multidisciplinary approach to the problem.
对阿盖尔郡阿尔托伊海洋渔业管理局海洋养殖单位养殖的大比目鱼出现的眼部异常进行了临床和死后调查。发现大量鱼有后极囊性变化,要么导致巩膜扩张,要么导致后段严重退行性异常并伴有脉络膜视网膜萎缩。其他眼部异常包括白内障形成和眼内炎症。在少数鱼中,在捕获和检查期间观察到前房有气泡形成。尽管这些鱼饲养的水箱中不存在先前报道的养殖鱼类气泡病的病因——过饱和,但这些鱼中出现的病变有可能是气泡病的一种形式。虽然本文没有提供有关这些病变病因发病机制的答案,但希望它能激发讨论,通过对该问题采取多学科方法来解决这些问题。
