投喂频率对虎龙斑摄食·生长·饲料转化率的影响

Effects of Feeding Frequency on Feeding,Growth and Feed Conversion Rate of Hulong Grouper

[目的]研究投喂频率对虎龙斑摄食、生长和饲料转化率等指标的影响。[方法]试验共设置5个处理组,对平均始重(6.42±1.09)g的虎龙斑(Hulong grouper)进行不同频率的投喂,研究不同投喂频率对虎龙斑摄食率、生长和饲料转化率等指标的影响。[结果]投喂频率对虎龙斑存活的影响较大,投喂频率对虎龙斑的摄食率(Feeding rate,FR)和饲料转化率(Feed conversion rate,FCR)有显著影响(P<0.05),但是投喂频率对虎龙斑末重的影响不显著(P>0.05)。[结论]该研究结果可为虎龙斑的科学养殖管理提供理论依据。

[Objective] To study how feeding frequency influences on the feeding, growth, feed conversion efficiency and other indices of Hu-long grouper.[Method] To set up 5 groups of different frequency of feeding, the average initial body weight of Hulong groupers （6.42 ＋1.09） g in the groups, effects of feeding frequency on feeding rate, growth, feed conversion efficiency and other indices were studied.[Re-sult] The results showed that feeding frequency influenced Hulong grouper survival rate, and had a significant effect （P 〈0.05） on feeding rate （FR） and feed conversion rate （FCR）, but had not a significant effect （P〉0.05） on the final body weight.[Conclusion] The results can provide a theoretical basis for scientific breeding and management of Hulong grouper.
