Abstract
In order to Comparison of reproductive biology Capoeta damascina and Capoeta trutta breeders were collected from the Gheshlagh River Sanandaj during reproduction season (June and July, 2017). Total length and weight in Capoeta damascina breeders was higher than Capoeta trutta breeders (P<0.05). Sperm volume, sperm density and spermatocrit in Capoeta trutta breeders was higher than Capoeta damascina breeders (P<0.05). The duration of sperm motility and the percentage of sperm motility was higher in Capoeta damascina breeders (P<0.05). PH and seminal plasma osmolality in Capoeta trutta breeders was less than Capoeta damascina breeders (P<0.05). Sex steroid levels of testosterone and dihydroxyprogesterone in Capoeta trutta breeders was greater than Capoeta damascina breeders (P<0.05) but 11- kettoesterone was not significantly (P>0.05). Histological studies in both group of breeders showed that the presene of spermatozoa cells in the lumen ducts which represent the onset of the stage spermatogensis in both group of fish, however, the distribution of spermatozoa cells in the lumen of Capoeta trutta breeders was more than Capoeta damascina breeders suggested that the testicle is more active in terms of sperm production.
