温室养鳖自九十年代初试验成功后,在南方各省得到了迅速推广。据浙江省杭州市养鳖协会调查,经过1994年至1996年的大发展,1997年全国甲鱼总产量达44460吨;1998年达6万吨。社会供应量的迅速增多,使得原本因江湖污染、人为滥捕、野生鳖骤减、价格暴涨的局面得以根本扭转。同时,各养殖单位依靠科技对养殖方式和技术进行了一系列改进,生产水平不断提高,生产成本不 After the success of the experiment in the greenhouse in the early 1990s, turtle cultivation in the southern part of the country has been rapidly promoted in various provinces in the south. According to the survey conducted by the Yangzhou Turtle Association in Hangzhou City, Zhejiang Province, after 1997-1996, the total output of soft-shelled turtles reached 44,460 tons in 1997 and 60,000 tons in 1998. The rapid increase of social supply has fundamentally reversed the situation that was originally caused by the pollution of the rivers and lakes, the indiscriminate arrest of wild animals, the sudden drop of wild turtles and soaring prices. At the same time, all breeding units rely on science and technology to conduct a series of improvements to their farming methods and techniques, continuously raise their production levels, and their production costs are not
