The dietary test shrimp, Penaeus orientalis, designed by means of the gradient method for linoleic acid and linolenic acid, showed that percentage weight gain and survival rate of the shrimp were affected by both content and ratio of linoleic acid and linolenic acid. In the present test the optimal requirement of shrimp for linoleic acid and linolenic acid in the diet respectively was 2.16% and 0.87%, with optimal ratio of the two fatty acids as 2.48, and the linoleic acid as an essential fatty acid is more effective than linoleic acid. In the shrimp practical diet containing lots of plant protein feedstuff rich in linoleic acid, the optimal percentage weight gain and survival rate of shrimp can be got by adding some level of linoleic acid and linolenic acid as there were the higher ratio and lower content of linoleic acid and linolenic acid in the diet
