摘要
用行为解析法研究三种不同口径鱼礁模型对黑鲷的诱集。结果表明：三种鱼礁模型对黑鲷具明显诱集作用，当模型放入后，鱼在模型放置区的分布率明显增加，群体重心在模型周围移动，个体间平均距离相对于无礁置放时减少。方差分析得知：三种不同口径的鱼礁模型对黑鲷的诱集作用无明显差别，说明黑鲷对不同口径鱼礁均表现出明显的趋集反应。
The attractive effect of 3 fish reef models of different diameter on black por-gy with behavioral analysis method is studied.Results shows:3 kinds of fish reef model have ob-vious attractive effect on black porgy.After the model is put in the pool,distribution ratio of fishin the reef region increase obviously,centre of gravity of colony moves around the model,aver-age distance between individual fish decreases compared with non-reef condition. Variance analy-sis shows:there is no obvious difference in the attractive effect of 3 kinds of fish reef models,andblack porgy shows obvious gather-taxis reaction to the fish reef model of different diameters。
