摘　　要： 为了解不同类型人工鱼礁的集鱼效果,在试验水槽内观察5种鱼礁模型对褐菖鲉Sebastiscus marmoratus(Cuvier etValenciennes)的诱集效果。结果表明:在未投放礁体模型时,试验鱼的密集区均出现在水槽的左端(A1、A6区域),出现率为63.87%,而试验鱼在空白礁区(A3、A8区域)的平均出现率低于1%;放入鱼礁模型后,鱼礁区(A3、A8区域)试验鱼的出现率分别上升至59.47%(B礁)、52.40%(C礁)、57.33%(D礁)、44.40%(E礁)、71.07%(F礁),而原密集区A1和A6区域试验鱼的平均出现率分别降至38.93%(B礁)、12.67%(C礁)、25.73%(D礁)、43.73%(E礁)、27.73%(F礁)。统计数据表明,5种礁体模型放入后,礁区内试验鱼的平均出现率与投放前相比均大幅度提高,说明5种模型礁对试验鱼均有较强的诱集效果,其中以有效空间较大的F礁效果最好。 Few studies had been done on the attraction effect of artificial reef on fish in China.In this paper,five different artificial reef models were put into the experimental trough to observe the behavioral response of fish Sebastiscus marmoratus（Cuvier et Valenciennes）.The results showed that in the condition without artificial reef models in the trough,Sebastiscus marmoratus（Cuvier et Valenciennes） preferred to stay in the left edge areas（Area A1 and A6） of the trough.The average occurring rate of fish in both areas of A1 and A6 was about 63.87%,while the average occurring rate of fish inside the blank reef areas（Area A3 and A8） was less than 1%.After the artificial models were put into the trough,average occurring rates of fish inside the reef areas（Area A3 and A8） increased to 59.47%（Model B）、52.40%（Model C）、57.33%（Model D）、44.40%（Model E）、71.07%（Model F）,while those in the left edge areas（Area A1 and A6） of trough reduced to 38.93%（Model B）、12.67%（Model C）、25.73%（Model D）、43.73%（Model E）、27.73%（Mode Fl）.The results showed that all of five artificial reef models had obvious attraction effect on Sebastiscus marmoratus（Cuvier et Valenciennes）,especially for model F.
