摘要:

为解决中华乌塘鳢养殖对小杂鱼的饲料依赖,试验选取中华乌塘鳢越冬幼鱼为研究对象,随机分为白鲢鱼肉组(HM组)、发酵饲料组(FD组)和梅鱼鱼肉组(对照组,小杂鱼,CTF组),每组3个重复,每个重复25尾鱼,试验期80 d。结果表明,与CTF组相比,HM组和FD组中华乌塘鳢的存活率分别显著(p<0.05)提高了19.51和21.92百分点,胃蛋白酶活性和淀粉酶活性显著提高。HM组、FD组和CTF组的增重率、特定生长率和肥满度均无显著差异。FD组形态学指标中肝体比显著低于CTF组和HM组。HM组、FD组和CTF组中华乌塘鳢的粗蛋白、水分、灰分、粗脂肪含量和脂肪酸组成均无显著差异。中华乌塘鳢的脂肪酸主要由C14:0、C16:0、C18:0、C16:1、C18:1、C20:1、C18:2、C18:3ALA、C20:4、C20:5、C22:6组成。与CTF组和FD组相比,HM组血清溶菌酶活性、肝脏溶菌酶活性和肝脏总抗氧化能力显著提高。与CTF组相比,FD组血清溶菌酶活性和肝脏溶菌酶活性显著下降,肝脏总抗氧化能力显著提高。综上所述,投喂白鲢鱼肉和发酵饲料均可以提高中华乌塘鳢的存活率,促进鱼体对蛋白质的消化吸收,改善鱼体免疫力,但不会显著影响中华乌塘鳢的生长性能和营养成分。

Abstract:

To address the feed dependence of Bostrychus sinensis on trash fish,the study selected overwintering juvenile Bostrychus sinensis as the research subject, and randomly divided them into three groups,the silver carp group(HM group),the fermented feed group(FD group),and the plum carp group(control group,trash fish,CTF group),with three replicates per group,each containing 25 fish,over an 80-day trial period. The results showed that compared with the CTF group,the survival rate of HM and FD group significantly(p<0.05)increased by 19.51 and 21.92 percentage points,and the pepsin activity and amylase activity of HM and FD group significantly increased. There were no significant differences in weight gain rate,specific growth rate,and fat full among the HM group,FD group,and CTF group. The liver to body ratio in the FD group was significantly lower than that in the CTF and HM groups. There were no significant differences in contents of crude protein,moisture,ash and crude fat,and fatty acid composition among the HM group,FD group,and CTF group. The fatty acids of Bostrychus sinensis mainly consist of C14:0、C16:0、C18:0、C16:1、C18:1、C20:1、C18:2、C18:3ALA、C20:4、C20:5、C22:6. The serum lysozyme activity,liver lysozyme activity and liver total antioxidant capacity of HM group significantly increased in comparison to CTF and FD group. Compared with the CTF group,the serum lysozyme activity and liver lysozyme activity of FD group significantly decreased,while the liver total antioxidant capacity significantly increased. In a word,feeding with silver carp and fermented feed can improve the survival rate,the digestibility of protein and the immunity of Bostrychus sinensis,without significant effect on the growth performance and nutrient composition of Bostrychus sinensis.

Key words: Bostrychus sinensis, silver carp, fermented feed, growth performance, nutrient composition, lysozyme
