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 habitat habits and the tolerance to salinity, temperature and pH of water environment were studied. Through the setting of red brick, acupoints, blocks and white plastic tube as a hidden place for the prometeus, the use of temperature-controlled electric rods and ice bag temperature and maintain the water temperature, with NaOH and HCl to adjust the pH of the water body, Add salt or fresh water to salvage the water. The test results show that, Chang Hsi hi habitat in brick, tile, stone, tile as the best place to conceal; like the bottom of the mud, drilling mud hole phenomenon; suitable salinity of 16.3 to 27.3, the optimum salinity The optimum temperature is 12 ~ 27 ℃; the optimum pH is 6.2 ~ 9.7, the optimum is 6.7 ~ 9.2.
