一、问题的提出我国是世界淡水养鱼历史悠久的国家。建国二十九年来,在毛主席的革命路线指引下,淡水鱼类养殖无论是基础理论或是应用技术都取得了很大的成绩。特别是家鱼人工繁殖研究成功,不仅从根本上解决了鱼苗的供应问题,同时为发展鱼类繁殖生理学这门学科奠定了良好的基础。由于林彪、“四人帮”的干扰和破坏,淡水渔业和与此相关的学科都受到损害和摧残。他们反对学习外国的先进技术,仇视基础科学。越来越多的事实说明,固守在传统的养殖经验水平上已不能适应现代渔业发 First, the issue raised China is the world’s fresh water fish has a long history of the country. Twenty-nine years after the founding of the PRC, under the guidance of Chairman Mao’s revolutionary line, great achievements have been made in freshwater fish farming both in basic theory and in applied technologies. In particular, the success of artificial reproduction of domestic fish has not only fundamentally solved the problem of supply of fry, but also laid a good foundation for the development of the discipline of fish breeding physiology. Due to the interference and destruction by Lin Biao and the “gang of four,” freshwater fisheries and the related disciplines have been damaged and destroyed. They are opposed to learning advanced foreign technologies and hating basic science. More and more facts show that sticking to the traditional experience of farming experience can not adapt to the development of modern fisheries
