Fish Reproduction

The present volume gives a comprehensive, integrated account of reproductive biology of a teleost. It summarizes and consolidates results obtained from diverse techniques–morphological, histological and histochemical, applied to the developmental processes involved in the growth, maturation, release and regression of the fish gametes. The book is illustrated throughout with photomicrographs and statistical graphics. After an introduction emphasizing the importance of fish reproductive biology for the fishery management, conservation and aquaculture. The testicular and ovarian morphology, histology, histochemistry and seasonal cyclicity of a snowtrout are described in detail along with a strong discussion about origin, structure, chemical composition and function of various gonadal components with other teleosts of diverse habitat. A further section incorporates the various aspects of fecundity and its relationship to different body parameters of fish describing the egg production potential of the species. The volume concludes by the detailed account of spawning ecology of the fish. The macro and micro environmental factors influences the development, maturity, cycling of gonads and spawning of fish are also discussed at appropriate places. An extensive list of references is appended. The volume not only provide the unique account of Snowtrout Reproduction but also give a deeper insight into the biology of Spermatogenesis, Oogenesis including Atresia and environmental influences on spawning activity. The book may help to explore the possibilities of improving fertility and will form an important basis for the development of cold water fishery in Central Himalaya.
