Over the period of April to November 1983, the shrimp, Trachypenaeus curvirostris(STIMPSON), were sampled monthly at fish markets in Gunsan to investigate some ecological characteristics. The spawning season was from May to September. The sex ratio of female to male shows seasonal variation with annual mean of around 76/24. The diameter of the egg ranges from 101μ to 188μ with a mode in 150μ during immatured stage, but with the coming of spawning time the egg size grows larger to 170~346μ with a mode in 250μ. The food items were mainly benthic animals such as polychaetes, cephalopods, crustaceans, etc.
