Cold storage of carp semen for short periods

Semen of common carp may be stored for periods of up to 45 h by cooling to temperatures between 0 and 5°C. No differences in fertilisation or hatching were found when eggs were fertilised with either cold-stored or fresh semen. Use of semen stored for short periods enables the separation in time between semen and egg collection. This may facilitate propagation of fish in hatcheries.
