Influence of the semen quality of maintaining males of Atlantic salmon, Salmo salar, in sea water during the breeding season

International audience We have shown previously that the semen collected from male Atlantic salmon kept in sea water has often a low quality. To check for the hypothesis that this could be due to contamination by urine, we have compared the characteristics of semen collected by stripping, with those...
