　　The feeding trials were carried out with freshwater crayfish (Procambarus clarkii) to evaluate the three feed stimulants betaine (Bet),squid extract (SE) and squid meal (SM) upon fish meal (FM) diets or bio-feed (BF) diets in which fish meal were partially replaced by bio-feed.Results showed the feeding stimulants had no significantly effects on growth.By the relative concentration of markers in the faeces and diets, the preference for each diet was estimated and it represented the best stimulant was the mixture of Bet, SE and SM.
