The Juveniles of tuna Sarda orientalis (Temminck and Schlegel), Euthynnus affinis (Cantor) and Auxis thazard (Lacepede) is dealt. The peak period of occurrence is July-September and the potential ground is of Thirumullaivassal, South of the other two species constituted 68.7 to 90.6% whereas the other two species constituted the rest. The food and feeding habits of these commercially important are described. Length-weight distribution, the spawning season, migratory habits and pattern or recruitment in the tuna fishery described and discussed. Analysis of length-weight data revealed no significant difference between the species and regression coefficient is found to be very close to 3.0.
