Description	Not Available The results of investigations on some aspects of the biology of Tachysurus caelatus and Osteogeneiosus militaris are presented. The fishes fed on crustaceans followed by fishes, molluscs and polycheates. Gestating males were found starving. The occurrence of mature females and gestating male parents indicate that T.caelatus, spawns during February-June and O.militaris during August-April. T.caelatus attains 50% maturity at a total length of 40.8 cm and O.militaris at 33.0 cm. Females predominant the catch of both these species. Fecundity varied from 44 to 81 ova in T.caelatus and 27 to 61 ova in O.militaris. The maximum number of incubated eggs recorded from oro – buccal cavity of T.caelatus and O.militaris was 54 and 56 eggs respectively. The length- weight relationships of these fishes pooled for both sexes are: T.caelatus: Log W= - 5.57881+3.24007 Log L. O.militaris: Log W = - 4.86014 + 2.92293 Log L. Not Available
