Abstract

The growth of the global aquaculture industry has been sporadic over the last 50 years, and the global production capabilities of culture and capture fisheries are almost comparable [1]. In Africa, fish culture has grown tremendously due to advances in feed formulation, and the use of better culture facilities such as cages [2]. Even as Asia has become elephantine in aquaculture, Africa as a continent is yet to report any important additions of aquaculture on the world ordered series even though there are many available natural resources in many regions of the continent [3]. Aquaculture continues to grow more rapidly than all other animal producing sectors. According to FAO [4], developing countries‟ contribution by weight increased from 73% in 1979 to 90% in 1998. However, this dramatic increase in production is skewed on a regional basis in favour of Asia. For example, in 1998, aquaculture productions by weight according to the region were as follows: Europe, about 5%; South America, less than 2%; Africa and Oceania, about 0.5% each [5,6]. Moreover, according to FAO (2000), the numbers of fish farmers in the world increased from 7.07 million in 1998 to 7.47million in 2000. The corresponding numbers for 1998 (2000) by region were: Asia, 6.67 (7.13) million; North and Central America, 191,000 (190,000); Africa 56,000 (75,000); South America, 41,000 (41,000) and Oceania 5,000 (5,000). Taken the above into consideration, Africa continues to be a minor player in the global aquaculture industry even though the continent has a natural potential for aquaculture production. Tilapia production which is aboriginal to the African continent has not seen any important growth or development. Nevertheless, according to FAO Africa still has a great potential. For instance, the black tiger shrimp (Penaeus mondon) which is cultured in Madagascar, Eucheuma seaweed in Tanzania and as well as abalone (Haliotis spp) in South Africa [7].
加纳水产养殖业发展综述
过去50年来,全球水产养殖业的增长一直是零星的,养殖和捕捞渔业的全球生产能力几乎相当[1]。在非洲,由于饲料配方的进步以及网箱等更好的养殖设施的使用,鱼类养殖得到了极大的发展[2]。即使亚洲在水产养殖方面已经变得像大象一样庞大,非洲作为一个大陆,尽管非洲大陆的许多地区都有许多可用的自然资源[3],但在世界订购系列中尚未报告任何重要的水产养殖增加。水产养殖继续以比所有其他动物生产部门更快的速度增长。根据粮农组织[4],发展中国家的权重贡献从1979年的73%增加到1998年的90%。然而,这种产量的大幅增长在地区基础上倾向于亚洲。例如,1998年各区域水产养殖产量按重量计算如下:欧洲约占5%;南美洲,不到2%;非洲和大洋洲,各约0.5%[5,6]。此外,根据粮农组织(2000年)的数据,世界养鱼户的数量从1998年的707万增加到2000年的747万。1998年(2000年)各地区的相应数字为:亚洲667万(713万);北美和中美洲,191 000 (190 000);非洲56 000 (75 000);南美洲41,000(41,000),大洋洲5,000(5,000)。考虑到上述因素,非洲在全球水产养殖业中仍然是一个次要角色,尽管非洲大陆具有水产养殖生产的天然潜力。罗非鱼生产是非洲大陆的土著,没有任何重要的增长或发展。然而,据粮农组织称,非洲仍有巨大潜力。例如,马达加斯加养殖的黑虎虾(Penaeus mondon),坦桑尼亚养殖的Eucheuma海藻以及南非的鲍鱼(Haliotis spp)[7]。
