Abstract
The study on gonadosomatic index showed that the weights of the ovaries follow regular cyclical changes in relation to the oogenetic activity in the gonad. This is indicated by the seasonal changes in the index values. In September, October, November, December, and January when the gonads are in the resting stage, the index is minimum (1.3134, 1.2571, 1.2849, 1.2956, and 1.3584 respectively). In maturing stage from February to April, the index increases (7.0336, 9.3535, and 9.6860 respectively) as a result of the high level of cellular activity in the ovaries. In May, it was 9.0872 and reaches to value 13.9404 and 19.0376 in June and July respectively, due to the increase in the number of oocytes of stage VI, indicating the spawning. In August and September, the values of the index decreases 6.8301 and 1.3134 respectively, indicating simultaneous lyses of unspawned oocytes. In the present study, cyclical variations in the gonadosomatic index of female fish of L. boggut from Kalu dam near Ahmednagar showed that weights of the ovaries followed regular cyclical changes concerning the oogenetic activity in the gonad. This was indicated by the seasonal alterations in GSI.
