中文摘要: |
使用增殖放流中常用的挂牌标志法、荧光标志法、剪鳍标志法对卵形鲳鲹尧紫红笛鲷和黑鲷3 种鱼,在10 mg/L 和20 mg/L 浓度的丁香酚溶液下分别进行标志。通过在模拟鱼类自然生活环境下观察鱼的行为,统计存活率和脱标情况来确定两个麻醉浓度和3 种标志方法对3 种鱼的影响。结果表明,10mg/L丁香酚对鱼苗的影响比20mg/L 丁香酚小遥对比存活率和标志成功率可知,卵形鲳鲹鱼苗适合在10 mg/L 丁香酚下进行荧光标志,紫红笛鲷鱼苗和黑鲷鱼苗适合在10 mg/L 丁香酚下进行剪鳍标志。 |
英文摘要: |
This article used the hanging scutcheon tag, visible implant fluoreseent tag and cutting fin tag of enhancement in 10 mg/L and 20 mg/L eugenol to Trachinotus ovatus, Lutjanus argentimaculatus and Sparus macrocephlus,then tried to simulate the natural living environment of these fishes to culture for a week. By observing the survival rate and the probability of sign off of fishes, this paper determined the effects of two anesthetic concentrations and three mark methods on the survival rate of the restocking fishes. The results showed that the effect of 10 mg/L eugenol on the activity of fish was smaller than that of 20 mg/L eugenol. Comparing the survival rate and sign of successful rate, we got a conclusion that visible implant fluoreseent tag in 10 mg/L eugenol was suitable for T. ovatus, cutting fin tag in 10 mg/L eugenol was suitable for L. argentimaculatus and S. macrocephlus. |
