Abstract

Fishes have a variety of size, colors, attractive and behaviors in the aquatic ecosystem. Consumption is therefore increasing rapidly in many countries, but the importance of fish in daily diet is not yet fully realized. It is still a supplemental diet to a large section, mainly considered low weight of rich and delicious food items. It contains high nutrients like calcium, cobalt, iron, iodine, phosphorus and vitamins. These are all the nutrients needed to meet the demand of the body with the control cholesterol levels in the blood and to produce immune power. The data on landing of fishes are helpful for food security and fisherman welfare. In the present study the fisheries data were considered on landing of Mallipattinam coast for one year. During the study period, there four different major groups of fishes recorded; pelagic fishes, demersal fishes, crustaceans and Mollusks viz., 40.9%, 19.9%, 13.3%, 8.3%, 9.2% respectively. Anthropogenic disturbances and climate changes are adversely affecting the fish populations and diversity.
