摘　　要：为筛选出生产虾蟹类水产颗粒饲料用黏合剂,选择海藻酸钠、明胶、膨润土、羧甲基纤维素钠4种黏合剂,用于小批量制作克氏原螯虾(Procambarus clarkii)颗粒饲料,并评价了其耐水性,溶失率及对克氏原螯虾摄食率的影响。养殖实验结束后,对添加不同黏合剂的饲料在水中的稳定性和溶失率进行观察和计算,并且通过比较不同黏合剂对克氏原螯虾摄食率的影响,以此作为指标来筛选出适宜克氏原螯虾饲料的黏合剂。结果显示,四种黏合剂耐水时间分别为45′24″、31′53″、37′09″、32′26″,其中海藻酸钠的耐水性能最好,在水中溶失率最小(26.21%);明胶溶失率最大(58.42%)。经过7 d的投喂,发现用海藻酸钠作为黏合剂对克氏原螯虾的摄食率影响较小,适口性较好。研究结果表明,四种黏合剂在相同添加量的情况下,海藻酸钠耐水性能最好,溶失率最小,是实验饲料小批量生产条件下虾蟹类颗粒饲料比较适合的黏合剂。In order to screen out the adhesives for the production of shrimp and crab aquatic pellet feed,four adhesives,sodium alginate,gelatin,bentonite and sodium carboxymethyl cellulose,were selected for the production of pellet feed of Procambarus clarkii in small batch.The water resistance,dissolution loss rate and its effect on the feeding rate of Procambarus clarkii were evaluated.After the culture experiment,the stability and dissolution loss rate of feed added with different adhesives in water were observed and calculated,and the effects of different adhesives on the feeding rate of Procambarus clarkii were compared,and the adhesives suitable for Procambarus clarkii feed were selected as indicators.The results showed that the water resistance time of the four kinds of adhesives was 45′24″,31′53″,37′09″and 32′26″,respectively.Sodium alginate had the best water resistance and the lowest dissolution loss rate in water(26.21%).The loss of gelatin was the highest(58.42%).After 7 days of feeding,it was found that sodium alginate as a binder had little effect on the feeding rate of Procambarus clarkii,and the palatability was better.The results showed that sodium alginate had the best water resistance and the lowest dissolution rate under the same dosage of the four kinds of adhesives,which was suitable for shrimp and crab pellet feed under the condition of small batch production of experimental feed.
