中文摘要	将平均体重为(25.2±1.7)g/尾的225尾鲫鱼(Carasslius auratus)随机分为5个处理,每个处理组3个重复,每个重复15尾。不同处理组的鲫鱼随机饲喂昆虫壳聚糖水平为0,0.25%,0.50%,0.75%和1.00%的饲料,研究昆虫壳聚糖对鲫鱼部分生长性能指标及肠道消化酶活性的影响。结果表明,昆虫壳聚糖的添加显著提高了鲫鱼的特定生长率和蛋白质效率(P<0.05),鲫鱼的生长性能未随昆虫壳聚糖水平的升高而不断增加,以0.50%壳聚糖水平组最佳;昆虫壳聚糖的添加显著提高了鲫鱼肠道蛋白酶和淀粉酶的活性(P<0.05),对肠道脂肪酶活性无显著影响(P>0.05),各个处理组中,以0.50%壳聚糖水平组肠道消化酶活性最高。综合分析上述结果后,认为昆虫壳聚糖在鲫鱼饲料中的适宜添加水平为0.50%。; This study was conducted to investigate the effect of chitosan from insects on some growth performance parameters and intestinal digestive enzymes activities of crucian carp(Carassius auratus).225 crucian carp with average weight(25.2 ± 1.7) g were randomly divided into 5 treatments of 3 replicates each,15 fish per replicate.The fish were fed 5 diets with different levels of insect chitosan(0,0.25%,0.50%,0.75% and 1.00%)randomly.The results showed that specific growth rate and protein efficiency of crucian carp were significantly affected by chitosan supplementation(P<0.05).While the growth performance was not continuously increased with the increasing level of chitosan from insects,treatment of 0.50% chitosan from insects was the highest among all the treatments.Protease activity and amylase activity in intestinal of crucian carp were significantly improved by supplementation of chitosan from insects(P<0.05),whereas lipase activity in intestinal was not affected significantly(P>0.05).Intestinal digestive enzymes activities of crucian carp in treatment of 0.50% chitosan from insects was the highest among all the treatments.Based on the above results,0.50 % chitosan form insects are recommended to supplement in diet of crucian carp.; 【作者单位】集美大学水产学院厦门市饲料检测与安全评价重点实验室；西北农林科技大学植物保护学院；集美大学,福建省高校水产科学技术与食品安全重点实验室；【作者英文名】ZHAI Shao-wei1,WANG Dun2,HUANG Cang-hai 1,3 (1.Xiamen Key Laboratory of Feed Quality Testing and Safety Evaluation,Fisheries College of Jimei University,Xiamen 361021,China;2.College of Plant Protection of Northwest Agricultural and Forest University
