【摘要】 在水槽内观测了许氏平鲉Sebastes schlegeli与大泷六线鱼Hexagrammos otakii幼鱼对两种不同结构PVC材料模型礁的行为反应,并对模型礁的集鱼效果进行了统计分析。结果表明:水槽内无论有礁还是无礁,两种鱼均喜欢栖息在水槽两端的角落或侧壁,在水槽的Ⅰ区和Ⅱ区的平均出现率为20%左右;大泷六线鱼与许氏平鲉的对礁接近行动指数,在方形礁角形格底板试验B1组中分别为1.12和1.03,在十字礁角形格底板试验B2组中分别为1.16和1.05,大泷六线鱼高于许氏平鲉,两种鱼对十字礁的接近行动指数和平均出现率要略高于方形礁。

【Abstract】 The behavioral response of juvenile Schlegel’s rockfish Sebastes schlegeli and fat greenling Hexagrammos otakii to two different structures and PVC material square reef models were observed in a flume.The attractive effects of the reef on the fish were analyzed.The results showed that the fish were distributed in both the corner and the edge of the flume with and without the reefs,and the average incidence of the fish was about 20% and higher in the district of Ⅰand Ⅱ than the rest in the experiment.The indexes of approaching behavior of fat greenling and Schlegel’s rockfish were 1.12 and 1.03 in the experiment B1,respectively and 1.16 and 1.05 in the experiment B2,respectively.The fat greenling had significant higher index than Schlegel’s rockfish.
