Effect of salinity on motility and viability of salmonid spermatozoa
L. Tomasik | A. Sobociński
Spermatozoa of trout (Salmo trutta L.), lake trout (S. trutta m. lacustris L.), rainbow trout (S. gairdneri Rich.), and brook trout (Salvelinus fontinalis (Mitch.)) kept at 8-10°C without water in various diluting fluids behaved in all media more or less similarly up to 8 hrs after stripping. Spermatozoa viability as tested after 20 and 32 hrs was found to decrease with time, the rate of this decrease (a reduction in number of active spermatozoa and-to a lower degree-a shorter period of motility) depending on a fish species and medium used.
