This study evaluated the effects of culture season and different stocking density on productivity of freshwater prawn that was raised in northern Thailand. The experiment was conducted at the Faculty of Fisheries Technology and Aquatic Resources, Maejo University, Chiang Mai, Thailand. This study was divided into two experiments; each treatment was replicated three times. The first experiment investigated the effect of climatic condition on the culture and production of freshwater prawn post larvae (PL 10; mean weight of 0.02 g) stocked in 400m2 ponds. Results of the first experiment revealed freshwater prawn raised during the dry season to summer obtained higher growth rate (0.19 g and 0.15 g/day) and survival rate (34.27% and 24.49%) than that of summer to rainy season (p
