我国地热水资源十分丰富,分布广泛,已吐露的地热水有3000余处,遍及全国700多个县、市,其中适宜于水产养殖直接利用的中低温水(20—60℃)尤为普遍。湖南地热水资源在全国列居第八位。据统计,全省经查明地热水状况的有165处。地热水以其保持恒定的水温为特点,虽地热水的化学类型较复杂,但大多数的水质指标,基本上符合渔业用水要求。地热水在水产养殖上的应用意义,归纳起来:对于引进的热带鱼、虾的越冬来说,水温乃是其关键。低温季节,用高于当地寻常水温蓄养亲鱼,能促进性腺发
Geothermal water resources in our country are very rich and widely distributed. There are more than 3,000 geothermal water that have been disclosed throughout the country, covering more than 700 counties and cities. Among them, moderate and low temperature water (20-60 ℃), which is suitable for the direct utilization of aquaculture, is especially common . Hunan geothermal water resources ranked eighth in the country. According to statistics, the province has identified 165 hot water conditions. Geothermal water is characterized by its constant water temperature. Although the chemical types of geothermal water are complex, most of the water quality indicators basically meet the requirements of fishery water use. The application of geothermal water in aquaculture, summed up: For the introduction of tropical fish, shrimp wintering, the water temperature is the key. During the cold season, raising broodstock with a water temperature higher than the local average can promote gonadal development
