ABSTRACT

The effects of different extenders and storage periods on the motility and fertilization rate of rainbow trout (Oncorhynchus mykiss) semen were evaluated after short-term storage. Semen was collected from anesthetized males by the abdominal massage. After determination of main semen characteristics, the pooled ejaculates were diluted with 4 different extenders at a ratio of 1:3, and stored at 4℃ for 72 h. During preservation, spermatozoa motility (%) were determined every 12 h. Fertilization was carried out using the dry fertilization technique. The sperm-egg ratio was approximately 0.5x106 sperm/egg for optimum fertilization success. The highest motility (64.4±5.27%) and fertilization rate (94.3 ± 0.58 %) were obtained from semen stored with glucose based extender after 72 h storage. These results indicate that glucose based extender is a better preservative than the other solutions used in the study for the short term preservation of rainbow trout semen.
