Abstract

In this study, oocyte POLARIZATION INDEX used as an indicator to determine physiological status of immature, premature and mature CASPIAN ROACH, Rutilus frisii kutum Kamensky, 1901.For sampling, 100 oocyte were selected randomly from immature, premature and mature fishes. Then oocytes were fixed and cuted in animal-vegetal pole axis. After cuting, oocytes were stained by hematoxylin-eosin.. According to nucleus localization, oocyte POLARIZATION INDEX were determined in all oocytes.Premature and mature oocytes were fertilized by sperm of male fish, then FERTILIZATION PERCENTAGE was caculated. Nucleus localization in immature fishes was centeral, medidatorial in premature fish and in mature fishes was in marginal (near to micropyle). It was a difference between (P<0.01) FERTILIZATION PERCENTAGE in premature fish (61 ± 3 % in average) and mature fish (93 ± 2 % in average). This study demonsrated that; oocyte POLARIZATION INDEX can be used as a good indicator for proper broodstock selection in CASPIAN ROACH.
