On the occurrence, size distribution, morphometry and feeding habits of the juveniles of Euthynnus affinis (Cantor), Auxis thazard (Lacepede), and Sarda orientalis (Temminck and Schlegel), along the Tuticorin coast, Gulf of Mannar

Abstract

Very little information is available on the fishery and bionomics of juvenile tunas from Indian waters. In the present account the juveniles of three species of tuna-like fishes occurring in the fishery along the Tuticorin coast have been studied and the results presented. Morphometric and meristic characteristics, the biology as well as the food and feeding habits of E. affinis, A. thazard and S. orientalis are dealt with in the report.
