Fishery and bionomics of tunas at Cochin

Abstract

As stated earlier, the Central Marine Fisheries Research Institute furnishes the production figures of various species of marine fishes based on multistage stratified random sampling techniques. For detailed biological investigations involving aspects of species composition, size, age, growth, spawning, maturity, food and feeding habits and other parameters, the Project has selected some important centres for tuna investigations which would help in monitoring the resources. The fishery and biological aspects collected from 6 centres viz., Mangalore, Calicut, Cochin, Vizh'njam and Tuticorin in the mainland of India, and from Minicoy in the U.T. of Lakshadweep are analysed and results presented in the ensuing section under different modules.
