Eknath, Samiran Nandi The diameter of fully swollen fertilized eggs is 4.1-4.8 mm, but their average diameter is 4.5 mm. In the second experiment, sexually matured females were exposed in the three photoperiod conditions for 30 days and the sampled fishes were sacrificed on 0, 15 and 30 days of exposure to know gonadosomatic index (GSI) and gonadal histology. The observed heterozygosity ranged from 0.096 to 0.774 whereas the expected heterozygosity ranged from 0.109 to 0.801. The mean GSI values, oocyte diameter and proportions of vitellogenic oocyte were maximum in the fishes of 06L:18D treatment indicating stimulation of vitellogenesis.
