To define what is taxonomy
To understand the importance of shellfish by studying two highly diversified phyla such as phylum Arthropoda and phylum Mollusca
To develop species identification skills
To understand the important features of Phylum Arthopoda and phylum
Mollusca along with different subclasses
To understand the importance of Crustaceans and Molluscans in Indian fisheries
To identify the commercially important species of Crustacean and Mollusca.
Theory
Study of external morphology and meristic characteristics of crustacea and mollusca.
Classification of crustacea and mollusca up to the level of species with examples of
commercially important species.
Study of external morphology. Collection, preservation and identification of
commercially important prawns, shrimps, crabs, lobsters, bivalves, gastropods, cephalopods
from natural habitats. Field visits for collection and study of commercially important
shellfishes.
