【摘要】 在实验室条件下,应用行为学方法,通过观察刺参(Stichopus japonicus)在有、无人工流条件下的行为反应特征以及刺参在有、无人工流条件下对2种不同形状和结构人工模型礁的行为反应观察和统计,分析和探讨了人工模型礁对刺参在有无人工流条件下的集参效果。研究结果表明:1.放礁前后水体中流态将会发生明显的改变,而且礁区前后流速、流向等都会发生显著的变化;2.在流的作用下刺参的行为将发生明显的变化,它会主动的避开强流的冲击,寻找流速小,流态较缓和的地方栖息;3.与无流时相比较,在有流的条件下礁的平均聚集率比较高:4.与无流时相比较,在有流的条件下刺参在礁上栖息的时间较长,而且栖息时间具连续性。更多还原

【Abstract】 Under the condition of the laboratory,using the behaviouristics method,through observing the behavior characteristic of Stichopusjaponicus under condition that with or without artificial current and the behavior of Stichopus japonicus reacting to two different form and structure artificial reef models under that condition,analyze and study the changes of gathering effect of artificial reef models to Stichopus japonicus under the different condition.It shows that:The obvious change will take place in the water body before and after putting reefs,and the velocity of current and the direction of current etc.of the reef district, will all change remarkably;Behavior of Stichopus japonicus changes obviously under the current condition,it avoiding strong impacting that flowing voluntarily,it looking for the velocity of current relatively small and the place where the current state relatively relaxes;Comparing with no current,the average gathering rate of the reef is higher incurrent;Comparing with no current,the time that the Stichopus japonicus habitat on the reef is relatively longer in current,and the time of habitat has continuity.更多还原
