Shellfish Breeding and Hatchery Management (2+1)

2.1.1 Introduction

Next to fin fishes, crustaceans such as shrimps, prawns crabs, lobsters, etc are of much biological and economical  importance due to their high value and ready market acceptance. This has motivated the scientists to work out the breeding programme of these species which has come a long way as on date. The neuroendocrime system and mechanisms controlling reproduction in crustaceans are similar to that of fishes with some deviations.  Being invertebrates, their reproduction involves more external and internal stimulii.

Reproduction in crustaceans is basically controlled by the hormones secreted by the glands present in different parts of the body.
