Abstract

Although experimental work is being carried out on commercial cultivation of marine prawns At a few centres in India, intensive culture technology to suit the varying ecoloigical and hydrobiological Conditions in different parts of the country is yet to tie developed and perfected. One of the constraints For increasing stocking density of prawns for obtaining maximum product inch per unit area is in adequate Water replenishment on which depend the vital factors affecting the well-being of the stock. As prawns Usually like to consume natural food items like algae rather than artificial food supplied such as pellets, An attempt to enhance their growth and fatten them by the latter is beset with diflsculties, unless they Are equally nutritious and well balanced. Another constraint in intensive culture of marine prawns Is the havoc caused by predators, particularly carnivorous fishes. The present paper examines these Problems and suggests ways and means of overcoming or reducing them.
