Length-frequency data of T. tfia/assinus collected during 1974-76 at Waltair from trawl catches, during 1972-76 at Mandapam from trawl catches, during 1981 at Cochin Fisheries Harbour from the catches of trawls, purseseines and gill nets and during 1981 and 1982 at Veraval from trawl catches are taken up for this study.
