Inter‐population ovarian fluid variation differentially modulates sperm motility in Atlantic cod Gadus morhua
This study tested the hypothesis that the effects of Atlantic cod Gadus morhua ovarian fluid on sperm motility variables are population specific. Sperm from a northern G. morhua population were activated in the presence of ovarian fluid from either northern or southern G. morhua at different concent...
