我国鳗苗资源较为丰富,1988年生产鳗苗约50吨左右,如按生长率换算,可生产成鳗5万吨左右。但由于鳗苗价格昂贵,养殖工艺复杂(需有热源和优良水质),以及养鳗土建设施投资庞大等多种原因,致使我国养鳗业发展极为缓慢,成鳗产量很低,据外贸部门1988年统计约在5000吨左右,长期以来,均以出口鳗苗为主。近年来,广东、福建、浙江、 China’s eel seedling resources are more abundant, in 1988 the production of eel seed about 50 tons, according to the growth rate conversion, can produce 50000 tons of eel. However, due to the high price of eel fry, the complex breeding process (with heat source and excellent water quality) and the huge investment in eel earthenware construction, the development of eel industry in our country is very slow and the output of eel is very low. According to the statistics of Foreign Trade Department The annual statistics are about 5,000 tons, for a long time, are mainly exported eel seedlings. In recent years, Guangdong, Fujian, Zhejiang,
