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种鱼礁模型对花尾胡椒鲷Plectorhynchus cinc-tus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和A6区),出现率为61.60%,而试验鱼在空白礁区(A3和A8区)的平均出现率低于5%;在A3和A8区中间放入鱼礁模型后,鱼礁区(即A3和A8区)试验鱼的出现率分别上升至32.53%(B礁)、37.60%(C礁)、20.93%(D礁)、28.13%(E礁)、29.20%(F礁),而原密集区A1和A6试验鱼的平均出现率分别下降至29.47%(B礁)、23.47%(C礁)、33.60%(D礁)、25.73%(E礁)、42.93%(F礁)。统计数据显示,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,其中有效空间较大,遮盖效果较好的C礁的诱集效果最好。
Few studies have been conducted on the attraction effect of artificial reef on fish in China. In this study, five dif- ferent artificial reef models were put into an experimental trough to observe behavioral responses of fish Plectorhynchus cinctus. The results showed that without artificial reef models in the trough, Plectorhynchus cinctus preferred to stay in the left-edge areas （Areas A1 and A6） of the trough. The average occurring rate of fish in Areas A1 and A6 was about 61.60%, while the average occurring rate of fish inside the no-reef areas （Areas A3 and AS） was less than 5%. After the artificial mod- els were put into the middle of Areas A3 and A8 of trough, average occurring rates of fish inside the reef areas （Areas A3 and AS） increased to 32.53% （Model B）, 37.60% （Model C）, 20.93% （Model D）, 28.13% （Model E） and 29.20% （Model F）, while those in the left-edge areas （Areas A1 and A6） of the trough reduced to 29.47% （Model B）, 23.47% （Model C）, 33.60% （Model D）, 25.73% （Model E） and 42.93% （Model F）. The results showed that all of five artificial reef models had obvious attraction effects on Plectorhynchus cinctus, and Model C had the best attraction effects due to its large available room and shade space.
