摘　　要：为了解不同光照条件下人工鱼礁的集鱼效果,观察了自然光、55W和26W3种光照条件下在试验水槽内六面锥型罩式水泥人工鱼礁模型对花尾胡椒鲷(Plectorhynchus cinctu)的诱集效果。结果表明,在未投入礁体模型情况下,试验鱼出现的密集区位于水槽左端区域,试验鱼在此区域的平均出现率分别为61.60%(自然光)、81.61%(55W)和82.07%(26W),而试验鱼在空白礁区的出现率均低于5%;放入礁体模型后,鱼礁区试验鱼的出现率分别上升至37.60%(自然光)、23.56%(55W)和15.75%(26W),而原密集区试验鱼的平均出现率分别下降至23.47%(自然光)、71.61%(55W)和67.59%(26W)。统计数据显示,六面锥型罩式水泥人工鱼礁模型对花尾胡椒鲷具有显著的诱集作用,其诱集效果随着光照强度的降低而减弱。In this paper, a concrete-made artificial reef model with the shape of hexahedral cone was put into the experimental tank to observe the attraction effects of the artificial reef model on Plectorhynchus cinctu under three illumination conditions of natural illumination, 55 W and 26 W. The results showed that without the artificial reef model in the trough, the fish tended to stay in the areas on the left of the trough. The average occurring rate of the fish in these areas under the 3 different kinds of illumination were 61.60% （natural illumination） , 81.61% （55 W） and 82.07% （26 W） , but it was less than 5% inside the blank reef areas. After the artificial model was put into the troughs, the average occurring rate of the fish inside the reef areas increased to 37.60% （natural illumination）, 23.56% （55 W） and 15.75% （26 W）, while that in the left areas of the trough reduced to 23.47% （natural illumination） , 71.61% （55 W） and 67.59% （26 W）. The results showed that the hexahedral cone shaped artificial reef model had obvious attraction effects on P. cinctu under the three kinds of illumination, and the attraction effects reduced with the weakening of illumination.
