Abstract:
In India scientific commercial farming of Macrobrachium is yet to get a start, the major constraint being the lack of seed. Seed collection from the natural sources alone may not be sufficient, and in such cases seed production in hatcheries is inevitable. This necessitates knowledge of the reproductive biology of the species technology development for brood stock and larval rearing, and the optimum conditions required for larval development to undertake large scale seed production.The present study was taken up with the major objectives of developing a proper, simple and feasible technology for the larval rearing of Macrobrachium, with special emphasis on. mass larval rearing suitable for commercial level operations.

Abstract:
The present work aims to study induced maturation of the pearl
oyster for induced spawning experiments. The work on larval development
was done with a view to developing techniques for the artificial rearing of
commercially important pearl oyster P fucata, and also to elucidate the
principles and problems of tropical bivalve larvae in general for detailed
investigations in the future. The present study is designed to probe into the details of the
basic aspects of the biology related to the hatchery technology of Pinctada
fucata and the understanding of the factors which influence induction of
maturation, spawning, larval rearing and spat settlement. This would go a
long way in the upgradation of hatchery technology of the Indian Pearl oyster
Pinctada fucata fora commercial level seed production..
