STUDIES ON THE SEASONAL HISTOMORPHOLOGICAL CHANGES IN THE OVARY OF INDIAN MAJOR CARP, LABEO ROHITA (HAM.)

Abstract

Seasonal changes with reference to histomorphological changes in the oocytes of a fresh water Indian major carp Labeo rohita have been described. The gonadosomatic index indicated that, the spawning seasons of Labeo rohita was in July and August. The different stages of oogenetic development were examined microscopically. The study revealed a close correspondence among gonadosomatic index, ova diameter and water temperature. It was concluded that five stages of oocytes developments of Labeo rohita under study were identified.
