摘　　要：研究了长蛸成体的栖息习性及对水体环境的盐度、温度、pH的耐受能力。通过设置红砖搭穴、瓦片搭穴、石块搭穴和白塑料管作为长蛸的隐蔽场所,使用控温电热棒和冰袋调温并保持水温,用NaOH和HCl调节水体的pH值,加食盐或淡水调配水体的盐度。试验结果表明,长蛸喜栖于砖、瓦、石块下,以瓦片为最佳隐蔽场所;喜欢泥质底,有钻泥打洞现象;适宜盐度为16.3-27.3,最适盐度为18.3-24.3;适宜温度为10-31℃,最适温度为12-27℃;适宜pH为6.2-9.7,最适为6.7-9.2。The habit and adaptability of common octopus Octopus variabilis to water temperature,salinity and pH were studied in a tank with a shelter of tiles,bricks,rocks and plastic tubes.During the experiment,the water temperature was regulated by an electric heater and ice packs,the pH values were controlled by addition of NaOH and HCl and the salinity was maintained by various proportions of fresh water and NaCl.The results showed that the common octopus tended to inhabit under the shelters of tiles,bricks and rocks and rested in the mud seafloor at a water temperature of 10 ~ 31 ℃,optimally ranging from 12 to 27 ℃,a salinity of 16.3 ~ 27.3,alternatively from 18.3 to 24.3,and the pH from 6.2 to 9.7 with the optimal range of 6.7 -9.2.
