Farming of Atlantic halibut Hippoglossus hippoglossus is a growing industry in Norway. This study comprises the first description of heart morphology in fish from one Atlantic halibut farm. Fish with no clinical signs of disease were randomly sampled (8 to 12 mo old, weight 1 to 50 g). The hearts were studied by light and electron microscopy and samples were taken from the kidney and pericardial cavity for bacteriological examination. Slight to severe changes were found in most hearts at all samplings. The most serious pericardial and myocardial changes were seen in larger fish (15 to 50 g). In some of the hearts the affected pericardium formed multifocal protrusions. Eight fish had an adhesion between the apex of the ventricle and the parietal wall of the pericardial cavity. Results of bacteriology and immunohistochemistry investigations for common disease agents were negative.
大西洋庸鲽（Hippoglossus hippoglossus）养殖在挪威是一个不断发展的产业。本研究首次描述了来自一个大西洋庸鲽养殖场的鱼类心脏形态。对无疾病临床症状的鱼进行随机抽样（8至12月龄，体重1至50克）。通过光学显微镜和电子显微镜对心脏进行研究，并从肾脏和心包腔取样进行细菌学检查。在所有抽样中，大多数心脏都发现了轻度至重度的变化。在较大的鱼（15至50克）中观察到最严重的心包和心肌变化。在一些心脏中，受影响的心包形成多灶性突起。八条鱼的心尖与心包腔的前壁之间存在粘连。常见病原体的细菌学和免疫组织化学研究结果均为阴性。
