Among the mi~ritimes tates of India, Kerala ranks first contributing to about 45% ofthe countrys lizardtish production. At Cochin Fisheries Harbour, this group contributes to an average of 3.05% of the total marine fish landings. Increased operation of shrimp trawlers is found to exert fishing pressure on the available stock. Caught mainly during monsoon months, lizard fishes are represented mainly by Saurida undosquamis and S.tumbil. positive correlation between rainfall and abundance of these species is noticed. Fishery of S.undosquamis is found supported by size groups 175 to 255 rnm during monsoon months and by size groups above 255 mm during postmonsoon months. Size at first maturity of S.undosquamis is 201-210 mm. Spawning season is prolonged with peak during October- December months. With lesser representation of ripe gonads in the catches, the species appears to breed away from the fishing grounds. Both juveniles and adults show a preference for smaller fishes such as Stolephorus.sp . Cannibalism is noticed in the group.
