摘  要：
为研究投饵率和水温对菊黄东方鲀健康生长的影响,选取体长为18.4~20.3 cm、体重为(243.30±34.37)g的菊黄东方鲀,随机分为饥饿组(不予投喂)、少量投饵组(投饵率1%)、对照组(正常投喂且水温控制在18~21℃之间)、高温组(正常投喂且水温控制在22~24℃之间)和低温组(正常投喂且水温控制在15~18℃之间)。经15 d试验后,观察菊黄东方鲀的外观形态,分析投饵率和水温对菊黄东方鲀健康生长的影响,为菊黄东方鲀的人工养殖提供科学依据。结果表明,试验15 d后,高温组的菊黄东方鲀增重率为-3%,低温组的菊黄东方鲀增重率为4%,对照组的菊黄东方鲀增重率为7%;饥饿组的菊黄东方鲀鱼鳍损伤率高达60%,少量投喂组的菊黄东方鲀鱼鳍损伤率为26.7%;高温组的菊黄东方鲀死亡率为20%,低温组的菊黄东方鲀无死亡现象。

摘  要：
In order to analyze the effect of feeding rate and water temperature on the healthy growth of Takifugu flavidus,this paper took Takifugu flavidus of 18.4-20.3 cm and(243.30±34.37)g weight as materials,which were randomly divided into hungry group(no feeding),a small amount of feeding group(feeding rate 1%),control group(normal feeding and water temperature of 18-21 ℃),high temperature group(normal feeding and water temperature of 22-24 ℃)and low temperature group(normal feeding and water temperature of 15-18 ℃).After 15 days,the effect of feeding rate and water temperature on the healthy growth of Takifugu flavidus were studied,and the scientific basis was provided for the artificial breeding of Takifugu flavidus.The results showed that the weight gain rate of Takifugu flavidus in the high temperature group was-3%,the weight gain rate of Takifugu flavidus in the low temperature group was 4%,the weight gain rate of Takifugu flavidu in the control group was 7%;the fins damage rate was up to 60%in hungry group,the fins damage rate was 26.7% in a small amount of feeding group;the mortality rate of Takifugu flavidus was 20% in the high temperature group,and there was no death in the low temperature group.
