The pxesent paper deals with the growth and feeding habits of the whitecrucian carp at different developulent stages under pond-rearing conditions in Sichuan. The relationship of body length (L)/age (t) falls on a striaght line, while that of weight(W)/age (t) is eapanential. The regression equation of length or weight and age are determined through calculation. The growth of the fingerling is vary fast in the first 20 days, aad gradually slower afterwards. The demarcatian is at the body length reached to 20 mm. The general length-weight equation of the crucian carp, based on the measurement of 3897 individuals, can be expressed as follows: 1-year W=0.00001314 L^3.2428 2-year W=0.00002232 L^3.8597 3-year ♂W=0.00002855 L^3.8797 Breeding season♀W=0.00005350 L^3.8797 The feeding habits of the fingerling indicates that the fry feeds on zooplankton mainly, it becomes to be omnivorous while the body length exceeds 23 mm.Intestinal contents show that at fry stage, the fish takes solely on zooplankton as soon as it begins feed. The adult takes more plants and debris than animals foods.
