| 摘 要： | 本文在实验室中水池中观察了赤点石斑鱼在三种不同口径鱼礁模型存在下的行为，结果表明；鱼礁对这种鱼有明显诱集效果，随着模型口径的增大，鱼在礁体放置区分布百分率有增大趋势，而鱼个体平均距离、群体总重心与礁体平均距离和鱼与礁的距离均有减小趋势。可见，口径大小的鱼礁模型有较好的聚鱼效果。

| Abstract: | The present paper records the observation of behaviour of garrupa on reef model with 3 different diameter under indoor pool condition and its comparison with non-reef condition.The results are as follows.Reef models have obvious attractive effects on garrupa; the distribution ratio of fish on reef region tends to increase along with the increase of diameter of reef modellbut without exception, the average distance between individual fish, average distance between the centre of gravity of colony and reef and average distance of fish and reef tend to decrease corre spondingly- It is thus clear that reef models of large diameter have obvious gathering effects. |
