Composition of the milt of some teleost fishes
The milt composition of six freshwater teleosts was studied, and the measured parameters showed clear specific differences between species. The highest spermatocrits and sperm densities were observed in perch, Perc afluviatilis , and burbot, Lota lota , and the lowest in rainbow trout, Salmo gairdne...
