Lesions of the biliary system in Atlantic salmon (Salmo salar L.)

Gallbladders with mucosal outpouchings (diverticula) were found in a population of Atlantic salmon farmed in sea water. Soft tissue calcification affected the skin, skeletal muscle and gut, as identified by histological observations. In addition, inflammation of muscle and intestinal tissue and lymp...

Description
Summary:Gallbladders with mucosal outpouchings (diverticula) were found in a population of Atlantic salmon farmed in sea water. Soft tissue calcification affected the skin, skeletal muscle and gut, as identified by histological observations. In addition, inflammation of muscle and intestinal tissue and lymphocytic and fibrous reaction were present in the liver. The general fish population was characterized by poor growth and unspecified mortalities. Here we describe the observed lesions and discuss them in the light of the general health status of the population.
