Abstract

The present paper comprises the results obtained in the experimental culture of the mud crab Scylla serrata in different types of cages in shallow bay of Tuticorin during 1978-79. The seeds were collected from estuarine area along creeks with its coastal mangrove swamps and impoundments and intertidal flats in and around Tuticorin. The young crabs were reared first in basket type cages made of cane splits for 2-3 months. Box type cages made of soft wooden planks, each comprising 8-10 compartments and metal framed synthetic twine mesh cages with compartment were preferred for culturing the grown up crabs. The crabs were fed with trash fish, clam meat and gutted wastes of the fish market. The growth rate of mud crabs in the existing environments appeared to be good as a good number of the stock moult frequently at an interval of 25-50 days. They were observed to reach marketable size through four—five moults in a period of 9-10 months. Eye stalk ablation accelerated the growth rate in young crabs and promoted gonadal maturation in adult crabs. Breeding behaviour Of this species was observed and discussed in brief.
