中文摘要：

用鱼类行为学方法，观测了许氏平蚰Sebastess chlegeli幼鱼在水槽内无模型礁和有模型礁条件下的行为反应，并统计分析了PVC材质的5种结构模型礁对许氏平铀幼鱼的聚集率。结果表明：水槽中无模型礁的条件下，标志区（模型礁设置区）的许氏平蚰聚集率为0，许氏平蚰选择光线较弱区域栖息：放入模型礁的条件下，5种模型礁均对许氏平蚰具有明显的诱集作用，群体重心在礁体周围移动，标志区对鱼的聚集率为56．7％-90％。方差分析结果表明：5种模型礁对许氏平蚰的诱集作用无明显差异，许氏平蚰对不同模型礁均表现出明显的趋集反应。

英文摘要：

The effects of five different cubic artificial reef models on behavior and distribution of juvenile schlegel＇ s rockfish （ Sebastes schlegeli Hilgendorf） were studied. The results showed that the juvenile distribution ratio of zero was found in the marked region（ the region where the reef model put in） when there was no reef model. The juveniles prefer weak light region to perch when the five kinds of reef models were put in the center of the tank, each of which showed a distinct preference in the marked area with distribution ratio of 56. 7% to 90%. Variance analysis showed that there was no significant difference in the attractive effect of the 5 kinds of fish reef models, and the fish had obvious gather - taxis reaction to the fish reef model of different structure.
