摘  要: 摸清多种人工鱼礁模型组合对紫红笛鲷幼鱼的诱集效果,可为人工鱼礁礁体组合设计和礁区布局设计等方面提供科学依据.本研究参照深圳杨梅坑人工鱼礁区的实际建礁情况,制作并模拟4组三种模型礁体组合、4组四种模型礁体组合,在方形试验水槽中以鱼类行为学的方法研究了这8组模型礁体组合对紫红笛鲷的诱集效果.4组三礁组合礁体模型试验结果表明,FHJ三礁组合对紫红笛鲷的集鱼效果非常明显,BFH、BCG、CHJ三礁组合对紫红笛鲷的集鱼效果较为明显.其诱集效果排序为:FHJ组合礁(53.84%)>BFH组合礁(44.85%)>BCG组合礁(38.11%)>CHJ组合礁(36.01%).4组四礁组合礁体的试验结果表明,4组四礁组合礁体模型对紫红笛鲷均具有较强的诱集效果,其诱集效果排序为:BGHJ组合礁(52.27%)>CFHJ组合礁(51.26%)>BCGJ组合礁(50.01%)>BCGH组合礁(45.05%).总体上,四礁组合的诱集效果优于三礁组合,人工鱼礁建设的礁群配置以多礁组合为佳. Artificial reefs are used in marine ranching to optimize marine ecosystems and enhance the fishery resources.Attractive effects of artificial reef may attributed by creating habitats,shelters and spawning grounds for various of fish,therefore favoring the breeding and growth of the fish.In recent years,artificial reef constructions have been forcefully promoted in China.However,the knowledge on the effects of artificial reefs on marine environment isn't clear and also for key techniques,which results in a certain blindness on the reef constructions.In present study,behaviors of Lutjanus argentimaculatus respond to 4 combinations of 3 reef models and 4 combinations of 4 reef models were investigated in experimental cylinder tank.Results showed that the attractive effect of different artificial models on Lutjanus argentimaculatus were in order of Model FHJ(53.84%),Model BFH(44.85%),Model BCJ(38.11%) and Model CHJ(36.01%).The attractive effect of different artificial models on Lutjanus argentimaculatus were in order of Model BGHJ(52.27%),Model CFHJ(51.26%),Model BCGJ(50.01%) and Model BCGH(45.05%).The present study aims to determine the influence of materials,structures and combinations of the reefs on the attractive effects of fish and provide useful data for developing the artificial reef constructions.It is noticeable that the condition of laboratory experiment is different from that of field.Therefore,it is reasonable that the results of attractive effects of artificial reef models on the marine organisms in the laboratory may differ from that in the sea.Thus,field studies,such as diving observation,are needed to investigate the aggregating effect of the methods,to determine in situ the attractive radius of the reefs with relations of laboratory experiment to the filed observation in order to provide useful information on the materials and structural design in combinations and configuration of the reefs.
