Abstract: Compare the effect of feeding biology feed and general feed to breed crayfish to value the biology feed effect by observing and mensurating the crayfish’s growth rate and the gonad growth. The results show that the biology feed are excelled than the general feed on the amino acids kinds and the content of the EAA especially namely the otherness on EAAI is prominent. The average growth rate of the biology feed and general feed are 1. 75 % and 1 .48% after two months feeding. There are some different degree otherness on the gonad growth coeffidents , the ratio of the liven to body and the comparative eggs quantity, after math statistic checkout, the otherness on body growth and gonad growth between biology feed and general feed to feed caryfish is prominent, the study indicate that the biology feed have good value to crayfish and aquiculture.
