Abstract: The research has been carried out at a carp farm in Cobanlar village which is 18 km far from Sinop using ovigerous females of 20 crayfish (Astacus leptodactylus Esch. 1823) from Bafra Fish Lakes. The larvae has been hatched at an average water temperature of 23.9±0.24°C in 19.05.1994. After hatching, the larvae have left the females after 10 days. Afterwards two ponds of earth with dimensions of 2x3x0.9 m were used in order to observe the growth performance. About 250 individuals of larvae of crayfish were placed into each pond. Farm dung was used in one of earth ponds in order to enrich the natural food in the environment and the young individuals of the first group were fed on natural food while trout pellets were used in the second group which was maintaned in the other pond. According to the end of study, it has been recorded that growth in the pond where trout pellets were used proved. T-test controls showed that the difference is considerable (p<0.05).
