Abstract
A study was conducted to determine how rice (Oryza sativa and crayfish (Procambarus clarkii) affect each other in the field and to determine optimal stocking rates of crayfish. High rice production correlated (P <0.01) with large numbers of adult crayfish present during the rice-growing season. Average crayfish production was significantly (P <0.05) higher in rice ponds (1,059 kg/ha) than in control ponds (800 kg/ha). Von Bertalanffy's growth model revealed that the average maximum length attained by crayfish in rice ponds (123.2 mm) was greater than in control ponds (106.9 mm).Keywords
