The effect of shelter on welfare of juvenile Atlantic salmon Salmo salar reared under a feed restriction regimen
This study investigated whether shelter (presence or absence) affected the frequency of fin damage in Atlantic salmon Salmo salar exposed to feed restrictions (0·73 or 0·33% of body mass day −1 ). The presence of shelter had a positive effect on the pectoral fins at both feed ration levels and on th...
