Summary

FACTORIAL ANALYSIS OF CORRESPONDENCES BETWEEN THE PHYSICO-CHEMICAL CHARACTERISTICS AND THE FERTILITY OF SPERM AFTER 5 TO 9 MONTHS FREEZING REVEALED THAT THE FITNESS FOR CRYOPRESERVATION CAN BE PARTICULARLY CHARACTERIZED BY THE COMPOSITION OF THE SEMINAL PLASMA: SPERM WITH THE LOWEST CAPACITY TO FERTILIZE WERE ASSOCIATED WITH A HIGH PLASMA OSMOLARITYAND/OR A HIGH LEVEL OF 42 KD PROTEIN, ONE OF THE MAJOR COMPONENTS OF THE SPERMATOZOAN MEMBRANE ; SPERM WITH THE HIGHEST FERTILIZING ABILITY LACKED 42 KD PROTEIN IN THE SEMINAL PLASMA. THESE RESULTS SUPPORT THE IDEA THAT THE FITNESS FOR CRYOPRESERVATION OF TROUT SPERM PRIMARILY DEPENDS ON THE CONDITION OF THE SPERMATOZOAN MEMBRANE.
