Cataracts in farmed Atlantic salmon ( Salmo salar) in Ireland, Norway and Scotland from 1995 to 1997
From 1995 to 1997 cataracts were observed in Atlantic salmon ( Salmo salar ) in Ireland, Norway and Scotland at around the time of smoltification (when freshwater fish become adapted to the hypertonic seawater) in both fresh‐ and seawater fish. Over 38,000 fish were screened for the presence of cata...
