Size frequency distribution of Trachtnocephalus myops (Schneider) showed that the species grows 10 mm per month in specimens measuring 70-240 mm. Analysis of stomach contents revealed that teleosts and crustaceans are chief constituents of food, Leiognathus sp., Stolephorus sp., Penaeus sp., Metapenaeus sp. and Solenocera sp. being the important food items. From the frequency distribution of intra-ovarian eggs, spawning period is taken to be April to June. Generally females dominated over the males in percentage contribution. The ovaries of mature females contained an average of 18,545 eggs.
