长沙市郊区现有养鱼水面22824亩,由于地处城郊,发展渔业生产具有肥、饲料丰富、劳力充足、市场广阔的特点,尤其是养殖罗非鱼更具有得天独厚的优势。1962年以来就从外地引进非洲鲫鱼试养,由于不能在长沙地区水域自然越冬,因此发展速度缓慢,始终未形成生产力。1974-1982年间,通过用电,烧煤加温等方法初步解决了罗非鱼的人工越冬问题,但是,由于耗能大、成本高,未能尽快普及推广。1982年郊区湘湖渔场首先试验利用地下水为热源,使大批罗非鱼人工安全越冬取得成功之后,全郊推广湘湖的经验,大抓越冬温室建设;基本上解决了苗种自给。此
The existing 22,224 mu of aquaculture water in the outskirts of Changsha City is located in the outskirts of the city. Due to its advantages of abundant fertilizer, abundant feed, abundant labor force and broad market, it is more advantageous to develop tilapia. Since 1962, introduction of African crucian carp from the field has been tried out. Since it can not naturally wintering in the waters of the Changsha area, its development has been slow and its productivity has not yet been formed. During 1974-1982, the problem of artificial overwintering of tilapia was initially solved by means of electricity and coal heating. However, due to high energy consumption and high cost, the promotion of tilapia was not popularized as soon as possible. In 1982, the suburbs of Xianghu Fisheries first experiment using groundwater as a heat source, so that a large number of tilapia artificial safety win over the success of the whole country to promote the Xianghu experience, pay more attention to winter greenhouse construction; basically solved the seed self-sufficiency. this
