近几年,天津市利用地热水培育越冬尼罗岁非鱼苗种工作取得了很大的进展,1983年春在大港区万家码头村,利用地热井建成尼罗罗非鱼苗种基地,占地面积约300亩,每年所提供的苗种数约占全市养殖需要量的三分之一。由于该地热井水含氟量高达9ppm,超过国家渔业用水标准(不超过1ppm)8.7倍,在销售时对越冬池水和苗种进行了氟含量的测定分析。结果表明,万家码头越冬地热池水含氟量严重超标,鱼种肉氟蓄积高达30ppm。因此,这就涉及到地热井水越冬罗非鱼苗种养成商品鱼的含氟量是否影响
In recent years, great efforts have been made in Tianjin to cultivate the Nile tilapia non-fry seedlings with geothermal water. In the spring of 1983, the Nile tilapia seedling base was built in Gejiu Wandou Village, Dagang District, An area of about 300 acres, the annual number of seedlings provided about one-third of the city’s breeding needs. As the geothermal well water fluorine content as high as 9ppm, more than the national fishery water standards (not more than 1ppm) 8.7 times, at the time of sales overwintering pool of water and seed were measured fluorine content analysis. The results showed that the water level of Geothermal water in Wanji Wharf was seriously exceeded and the amount of Fluorine in fish species was as high as 30ppm. Therefore, this involves the geothermal well water overwintering tilapia fish products to develop the fluorine content is affected
