摘　　要：在饵料中添加不同含量的免疫增强剂(0.2%、0.5%、0.8%)连续投喂21 d。分别在投喂后0、1、4、71、42、1 d检测河鲫鱼血液白细胞的吞噬活性、血清和体表粘液的溶菌酶活性。结果表明,该免疫增强剂可使河鲫鱼血液中白细胞吞噬活性、血清和体表粘液的溶菌酶活性都有明显提高。在停止投喂后7 d,血清溶菌酶的活性逐渐降低,与对照组无显著差异(P>0.05);但白细胞吞噬活性依然显著高于对照组(P<0.05)。To determine the effects of immuno-stimulants on innate immune response of Carassius auratus, fish were fed diets containing 0 （control）, 0.2%, 0.5%, 0.8% immun-stimulants for 1, 4, 7, 14 and 21 days. The results showed that the phagocytic activities were greatly increased and the lysozyme activities were obviously enhanced. This significant difference of the lysozyme activities disappeared 7 d after the fish stopped feeding mixed diet （ P 〉 0.05） ,while the phagocytic activities were obviously holding （ P 〈 0.05）.
