In this article we describe basic aspects of the sperm biology of lebranche mullet (Mugil liza) in the wild and in captivity, in particular assessing the effects of salinity (0, 10, 20, 30, 35, 40, 50 and 60 g L−1) and pH (6, 7, 8, 9 and 10) on sperm motility. Our results indicate that the highes...
