Endocrine Glands of the Fish

Notopterus Notopterus

By

Raghavendre S. Kulkarni

Preface

This manuscript entitled "Endocrine glands of the fish, Notopterus notopterus "has been prepared keeping in view of not availability of methodology being adopted for endocrine studies in fish particularly and this complete manuscript is a outcome of my over a 30 years period of my teaching and research experience for post graduate and research students. A comprehensive account of a particular fish species on endocrine glands was not available and I thought that this could help our young researchers carrying research work on comparative endocrinology and more specifically with reference to fish endocrinology and reproduction. With my experience in handling the fish tissue during my doctoral and post doctoral studies at Banaras Hindu University, Varanasi under a eminent fish endocrinologist Professor A.G.Sathyanaesan made me to continue my previous research work and further carryout research work on fish endocrinology and biology of reproduction here at Gulbarga University, Kalaburgi on my appointment in the Department of studies and Rresearch in Zoology. I feel and hope the methodology given in this manuscript may help and inspire to carry out the research for future group of students joining research in the field of fish research in the coming years.
