非洲鲫鱼原产于热带,不耐冬季低温,在两广等地能自然越冬,北方能不能养,有没有生产意义?一直是个疑问。1969年,北京市朝阳区从广东引种非洲鲫鱼,现已渡过了五个严冬,经几年来试验、推广,具有较好的生产意义。生产队社员感到这种鱼好养,生长快,产量高,又能以活鱼供应市场;城市居民则认为这种鱼的肉味鲜美,价格便宜。 African crucian carp native to the tropics, intolerant of winter temperatures, in Guangdong and Guangxi and other places can naturally wintering, can the North raise, there is no production sense? Has been a question. In 1969, the introduction of African carp from Guangdong Province in Chaoyang District of Beijing has now passed five severe winter months. After years of testing and promotion, it has good production significance. Production team members feel that this kind of fish is well-fed, fast-growing, high-yielding and able to supply the market with live fish. Urban residents think the meat is delicious and cheap.
