摘要
在室内试验条件下研究了温度、光照和规格对硬壳蛤稚贝潜砂活动的影响。结果显示,温度、光照和规格对硬壳蛤稚贝潜砂活动都有显著影响(P>0.05)。在水温8℃以上稚贝能够在较短的时间内潜砂,1小时内80%的稚贝能够潜入到砂中。光照强度的增加能提高稚贝潜砂的比例,3000～4000lx的光照下,90%左右的稚贝在2小时内潜入到砂中。10mm稚贝的潜砂比例要高于8mm和20mm的稚贝。
The influence of temperature,light and body-size to the digging behavior of the juvenile was studied under indoor conditions.The result indicated that all the three factors affected the digging behavior apparently:there were 80% of the juvenile digged into the sand in 1 hour when the temperature was above 8℃;the increasing of the light intensity would improve the rate of the digging ones and when the light intensity was 3 000～4 000 1x,90% of the juvenile digged in 2 hours;the rate of the digging ones at 10 mm was higher than that of the 8 mm and 20 mm ones.
