摘要: 对采自青岛近岸的马粪海胆进行温度、盐度、光强与底质等因子的耐受及选择实验.结果表明,青岛近岸马粪海胆的适温范围约在8~22℃,对温度的选择受驯养水温的影响;属窄盐性种类,适盐范围约在30~35;喜好弱光环境,饥饿状态的选择光强(8~25lx)较非饥饿状态(10~35lx)低;对粗沙砾底质具明显的正选择,而对细沙性底质呈明显的负选择.

Abstract: An experimental ecological study of sea urchin (Hemicentrotus pulcherrimus) sampled from coastal waters of Qingdao was focused on the fundamental ecological factors such as temperature, salinity, light intensity and substratum. The results showed that the suitable ecological range of temperature was from 8 ℃ to 22 ℃, and the selectivity to temperature was changed with the previous living temperatures. Hemicentrotus pulcherrimus was a kind of stenohaline creature. Its optimum ecological range of salinity was from 30 to 35. The results also showed that Hemicentrotus pulcherrimus liked to select weak light environment (<50 lux), especially under non food condition. Hemicentrotus pulcherrimus had the positive substratum selectivity to coarse sand and the negative substratum selectivity to silver sand.
