Suspected myocardial necrosis in farmed Atlantic salmon, Salmo salar L.: a field case
Abstract Arteriosclerosis of the coronary artery has been described as a ‘fact of life’ for Pacific and Atlantic salmonids due to the high prevalence in spawning fish. The lesions are believed to be the result of overstretching of the highly distensible bulbus arteriosus whereby the endothelium of t...
