| 摘 要： | 采用鱼类行为学方法,观测了短蛸(Octopus ocellatus)对同为PVC材质的3种形状的有孔和无孔模型礁以及对同为管状的3种不同材料的单体和叠加模型礁的行为反应,并对各组内模型礁的诱集效果进行了比较.实验结果表明:未投放模型礁条件下短蛸在水槽四角分布率较高,在鱼礁标志区分布率只有0.5%;PVC材质3种形状的模型礁放入后对短蛸的聚集率均在10%以上,其中内部空间最大的正方体模型礁聚集率最大,每种形状的模型礁中有孔模型礁聚集率高于无孔;3种不同材料的管状模型礁放入后诱集效果均较明显,其中陶瓷材质的管状模型礁效果最好,每种材料的模型礁中3单体叠加后的组合礁聚集率明显高于单体,其中叠加后的陶瓷模型礁对短蛸的聚集率达到39.3%;研究发现短蛸的领域行为对鱼礁模型的诱集效果影响较大.

| Abstract: | The behavioral response of Octopus ocellatus to three PVC material artificial reef models with different shapes and three tubular artificial reef models with different materials were studied in a flume.The attractive effects of the reefs on Octopus ocellatus were analysed.The results showed that Octopus ocellatus had a higher distribution in the corner of the flume when there was no reef model,the distribution rate of the marked area was 0.5%.When the three shapes of PVC material reef models were put in,the... |
