Histomorphological study on the ovary of Mugil auratus (Risso)

It is observed that certain morphological ovarian characteristics such as colour, size, and position in the body cavity, do not indicate the actual developmental stages of the ovary Histological study assists in pinpointing the real state of the ovary which in turn helps in better planning for fishing and possibly for artificial propagation of various fish species. The present study on Mugil auratus is an effort to understand its ovarian developmental cycle by histological analysis of the ovaries referring to their morphological changes. Such works had been done earlier on northern part of the Caspian Sea, but it has not so far been worked out in southern part of it. During the course of one year study, specimens of Mugil auratus were caught every month from wild population, for histomorphological studies, considering the GSI as the main index. Based on histomorphological studies six ovarian stages have been recognized which are named as 1- immature, 2- early maturing, 3- late matur.....
