世界罗非鱼捕捞和养殖的动态特征研究

罗非鱼类原产于非洲和东南亚，具有生长迅速、耐粗食、肉质好等优点，目前已成为世界渔业的重要鱼品。世界罗非鱼生产以捕捞和养殖两种方式进行。九十年代，世界罗非鱼养殖业迅速崛起，养殖产量开始逐渐超过捕捞产量。世界罗非鱼养殖主要品种是尼罗罗非鱼。与此同时，世界罗非鱼的加工与贸易，亦有比较快速的发展。根据1981—2002年FAO关于罗非鱼捕捞和养殖的统计资料，分析了世界罗非鱼产业的动态特征，目前中国罗非鱼养殖年产量世界第一，有必要继续关注和提升中国罗非鱼养殖业发展的世界地位。

Study of dynamic characteristics of world tilapia capture and aquaculture industry

The genus tilapia native to Africa and South-east Asia has been an important food fish in the world,which grows fast,eats roughage and tastes good.Tilapias are supplied by two normal ways,that is capture and aquaculture.In 1990's,the aquaculture of Tilapia grows up into the world and the output of the aquaculture increasingly exceeds that of the capture.The main breed of tilapia aquaculture is the Nile tilapia.In the meanwhile,the processing and trade of tilapias develop rather rapidly.On the basis of the statistics from 1981-2002 about the tilapia capture and aquaculture furnished by FAO,the paper analyzes the dynamic characters of the industry of tilapias.Since the output of China's tilapia aquaculture ranks first in the world,it is necessary to promote it to a higher position.
