摘　　要：在基础饲料中分别添加0.5%、1%和2%的壳聚糖,连续投喂花鲈(Lateolabrax japonicus)60d,探讨壳聚糖对花鲈生长和非特异性免疫力的影响。结果表明,添加0.5%和1%壳聚糖可以显著促进花鲈的生长,但是不同添加浓度对成活率均无影响。在30d时添加0.5%或1%壳聚糖能有效提高花鲈的补体活性、溶菌酶活性和吞噬活性;在60d时仅明显提高补体活性。添加壳聚糖对白细胞的数量没有影响。Japanese sea bass （Lateolabraxjaponicus） was fed with basal diets respectively supplemented with 0.5%, 1%, 2% chitosan for 60 days, in which the lysozyme activity, complement （CH50） activity, phagocytic activity and leukocyte number were examined continuously. The results showed that the growth of Japanese sea bass was significantly improved when dietary chitosan level was 0.5 % or 1%, but there was no signiticant impact on survival rate. The activity of total complement, lysozyme activity and phagocytic of the fish fed by diets with 0.5 % or 1% chitosan showed significant enhancement than that of the fish fed by diets with no chitosan or 2 % level after 30 days of treatment, but signiticant increase of total complement activity was observed only after 60 days. Total leucocyte number were unaffected by dietary chitosan.
