【Abstract】 What is the most economic size for the cultured shrimp? This problem is deeply concerned by all engaged in shrimp culturing. For this, a food (Aloidis sp. ) coefficient for different size shrimps is obtained according to the growth equation of the shrimp-(P. orientalis)the equation of the feeding amount (F = 0.0363L1.6722) and the relation equation (Y = 0.0574x - 0.154) between body length and eye handle.The result indicates the economic effect is different for different size shrimps.The shrimp reaching to the size of 12 and 14 cm in length is most profitable.更多还原
