Course Syllabus

Theory

Natural seed resources, site selection and collection methods. Life cycle of important shellfish (Penaeus monodon, P. indicus, Macrobrachium rosenbergii, P. Vannamei, Scylla serrata, lobster, edible, oyster, pearl oyster, fresh water mussel, holothurians, horse-shoe carb, Sepia, Loligo, cray fish etc.). Sexual maturity and breeding seasons of different species. Maturation stages of Macrobrachium rosenbergii and Penaeus monodon. and P. Vannamei. Induced maturation in Penaeus monodon and P. Vannamei P. Indicus by eye stalk ablation. Reproductive physiology. Reproductive harmones in crustaceans. Brood stock management of Penaeus monodon and Macrobrachium rosenbergii. Breeding and hatchery management of Penaeus monodon and Macrobrachium rosenbergii. Breeding and hatchery management of crabslobster, mussel, edible and pearl oyster. Food and feeding of larval stages of important shellfishes. Health management in hatcheries.
