摘　　要：研究了5种不同种类的粘合剂,分别为褐藻酸钠(SA)、卡拉胶(Car)、黄原胶(Xan)、明胶(Gel)、魔芋胶(Kon)对微颗粒饲料的物理性状如悬浮性、溶失率及大菱鲆稚鱼的生长、存活及消化酶活力的影响,并以添加淀粉组(Cont)和鲜活饵料(LF)作为对照。试验结果表明,大菱鲆稚鱼终体长Gel组显著高于Xan组和LF组,和其余各组相比差异不显著。而在大菱鲆稚鱼终重上,Gel组显著高于Car组、Xan组、Kon组、Cont组和LF组,但和SA组相比并没有显著差异。在特定生长率上,Gel组显著高于Car组、Xan组、Cont组和LF组,与Kon组、SA组差异不显著。消化酶活力测定结果表明,Gel组和SA组在60日龄肠段和刷状缘膜亮氨酸氨肽酶(ANP)和碱性磷酸酶(AP)比活力均显著高于其余各组。LF组和Xan组在60日龄刷状缘膜AP酶比活力显著低于其他各组。根据试验结果,明胶和褐藻酸钠适宜作为大菱鲆稚鱼微颗粒饲料的粘合剂。The effects of five different types of binders,sodium alginate（SA）,xanthan（Xan）,gelatin（Gel）,carrageenan（Car）,konjac gum（Kon）,on growth status and vitality of digestive enzyme of laval turbot（Scophthalmus maximus） were studied in this report.Feeding trials results show that the body length of fish fed with Gel group was significantly higher than that of Xan group and LF group.The final weight of fish fed with Gel group was significantly higher than Xan,Car,Kon,Cont and LF groups,but has no significant difference compared with SA group.To the specific growth rate,the Gel group was significantly higher than that of Xan,Car,Cont and LF groups,but has no significant difference compared with SA and Kon groups.Digestive enzymes activity testing indicated that the 60-day age lavae fed with Gel group and the SA group were significantly higher than the other groups in Leucine aminopeptidase（ANP） and alkaline phosphatase（AP） specific activity of intestine and brush border.60-day age lavae fed with LF group and Xan group were significantly lower than the other groups in brush border membrane AP enzyme specific activity.Based on the experimental results,two types of binders,Gel and SA were suitable as the binders of microdiets of turbot.
