| 摘 要： | 于1999年5月在集美大学水产学院海水养殖试验场进行中国龙虾栖息习性的试验观察。结果表明 ,正常温度、盐度条件下 ,中国龙虾有隐匿穴居、昼伏夜出的栖息习性 ,喜欢栖息于紧身或身体易于找到依靠的水平洞穴中 ,并有同穴共居现象 ,低层洞穴的栖息率高于高层洞穴 ;温度低于12℃时 ,中国龙虾夜间也很少离穴活动 ,温度低于8.6℃或高于34℃ ,盐度低于14.1或高于44.6时 ,中国龙虾都会逃离洞穴

| Abstract: | Some juvenile lobsters (B.L.=16.6± 2.6 cm) which collected from the wild were cultured in the pond to observe their roosting habit in May 1999. The results of the experiment showed that the spiny lobster, Panulirus stimpsoni preferred to hide in the caves in daytime and out at night under the normal temperature and salinity condition. The lobster liked to roost in a horizontal and narrow cave. There was a phenomenon of several lobsters roosted in the same cave. The roosting rate in the cave of lower layer was more than that in higher one. Under the temperature below 12 ℃ the lobsters rarely left their roosting caves. When the temperature was above 34 ℃ or below 8.6 ℃ and the salinity was below 14.1 or above 44.6 the lobsters escaped from their roosting caves. |
