Abstract: Trial on finedly feeding Procambarus elarkii by using compound feed was carried out in the study. According to the level of protein feed, the three trial groups and one control were ensured. The result indicated that the three trial groups in the end weight was significantly higher than that of the control （P〈0.01）, among the third trial group was the highest one attained 21.65 g. Meanwhile the third trial group was significantly high than that of the first trial group in end weight, the second group was high than that of the first trial group. The analysis showed that yield can attain 260 kg/667m^2 with using compound feed, and 321 yuan of economic returns can he increased per 667 m^2. Therefore, it can efficiently use land resource and human resource.
