前言地热的渔业利用是我国近年来开展的一项水产科研项目的新内容。其目的主要是为了通过人工控制水温的技术措施,达到延长鱼类生长期,改变鱼类的性周期规律,培育大规格鱼种,缩短养鱼周期和增加产量。尤其是利用地热(或者包括电厂余热、太阳能)开展提前家鱼人工繁殖的试验研究,得到更为广泛的重视。如黑龙江、哈尔滨市水产研究所,内蒙古自治区水产管理站(电厂余热),北京市水产试验站、烟台地区水产研究所、张家口地区水产
Preface Geothermal fishery utilization is a new content of aquatic scientific research projects carried out by our country in recent years. Its main purpose is to achieve the purpose of prolonging the growth period of fish, changing the sexual cycle of fish, cultivating large-sized species, shortening the period of fish farming and increasing the output through the technical measures of artificial control of water temperature. In particular, the use of geothermal (or including power plant heat, solar energy) to carry out artificial reproduction of fish in advance pilot study, get more attention. Such as Heilongjiang, Harbin Institute of Fisheries, Fisheries Management Station of Inner Mongolia Autonomous Region (power plant waste heat), Beijing Fisheries Experimental Station, Yantai Institute of Fisheries, Zhangjiakou area aquatic products
