1. Shellfish breeding & Hatchery Management
Cultivable shellfishes of India:

Shrimps (Penaeids)
Prawns (Palemonids)
Crabs (Brachyurans)
Lobsters (Palinurids)
Molluscs
Oysters (Edible & Pearl oyster)
Clams
Echonoderms
Holothurians

2. Shellfish breeding & Hatchery Management
Need for seed production:
Naturally available seeds are not sufficient
Breeding seasons are limited to a particular period
Monsoon failures will prevent natural breeding
Quality seeds are required for high production
Survival is very low in natural conditions
Genetic qualities need to be preserved
An income generating activity
Scope for self-employment
Higher production and revenue for the country
Further development possible through seed production

3. Shellfish breeding & Hatchery Management
Important areas that can be worked in this are,
Broodstock collection and transportation
Captive broodstock development
Broodstock nutrition and maturation diets
Induced maturation and captive spawning
Genetic improvement through selective breeding and hybridization
Larval nutrition and management
Disease management and vaccination
Development of new varieties
