Abstract. An outbreak of infectious haematopoietic necrosis causing high mortality in rainbow trout fry occurred in New York State. Despite the fact that the hatchery effluent was recycled, spread of viral infection or of clinical disease was not demonstrated. Endocardial and glomerular endothelial necrosis and fibrinous peritonitis were among the histopathologic changes seen. Many of the signs and lesions were similar to those seen in infectious pancreatic necrosis.
