摘　　要： 为了解不同人工鱼礁的集鱼效果,在试验水槽内观察了深圳杨梅坑人工鱼礁区实际投放的10种礁体模型对黑鲷的诱集效果。结果表明,未投放礁体模型时,试验鱼在距离水槽中心40～70 cm的区域出现频次最高,且在试验水槽中分布较为分散。分别将10种礁体模型放入水槽后,对有礁及无礁时试验鱼随距离出现的频次进行曲线趋势回归显示,1-8号礁体模型试验中试验鱼出现频次最大的区域为距离水槽中心20～50 cm,而9号和10号礁为体试验鱼出现频次最大的区域则为距离水槽中心10～40 cm,分别比对照组试验鱼最大出现频次区域向中心点近移了20 cm和30 cm,说明10种礁体模型对试验鱼均有一定的诱集效果。对试验结果做模型礁诱集效率指数显示,模型礁体对试验鱼的诱集效果由强到弱分别为10号礁>9号礁>1号礁>2号礁>7号礁>4号礁>5号礁>6号礁>8号礁>3号礁。 Artificial reef was used in marine ranch to improve the marine ecological environment and enhance the fishery resources. Attractive effects of artificial reef may be attributed to creating habitat, shelter and spawning ground for the various kinds of fish, therefore positively affect the breeding and growth of the fish. In recent years, artificial reef construction programs have been rapidly developed in China. However, the knowledge of the effect of artificial reef on marine ecological environment is limited. The present study aimed to determine the influence of materials, structure and combination on the attractive effects of the artificial reefs and therefore provide useful data and information for the development of artificial reef construction. In the present study, the effects of ten kinds of artificial reef models with different shapes, which have been deployed in Yangmeikeng reef area, on the behavioral responses of the fish Sparus macrocephalus and the fish attraction effects of the artificial reef models were analyzed and compared with those without the artificial reef model in the trough. The result showed that in the condition without the artificial reef model in the trough, the fish liked to stay in radius of the center trough area within 40 - 70 cm. while the fish are more dispersed in the trough. After the artificial model was put into the troughs, the fish liked to stay in radius of the center trough area within 20 - 50 cm while No. 1 reef-No. 8 reef were put into the trough, the fish liked to stay in radius of the center trough area within 10 -40 cm while No. 9 reef and No. 10 reef were put into the trough. The average occurring rate of the fish inside and near the reef areas all increased, while comparing fish occurring rates in artificial reef areas with or without artificial reef. The analysis results showed that all of the ten artificial reef models have obvious attraction effects on S. macrocephalus, especially for model NO. 10. Its attraction effects ramk from strong to weak, respectively N
