Abstract
Survival of sperm from Salmo trutta L., Salmo gairdneri Rich., Salvelinus fontinalis (Mitch.) was investigated at constant temperatures (1.0°; 5.0°; 10.0°; 15.0°C). The longest period of survival has been found to take place at the temperature range from 1.0°- 5.0°. Further it has been stated that the duration of sperm storage at various temperatures has only a slight influence on the activity time of spermatozoa. Differences have also been revealed with regard to various fish species, fish individuals, as well as individual spermatozoa.
