Aquaculture produces about half the fish consumed globally and is the fastest-growing food sector. In Africa, fish is one of the major sources of animal protein, and although the need for increased production of farmed fish to make up for the decline in capture fisheries is acknowledged, efforts put into aquaculture in the continent have not yielded commensurate results. The success recorded in aquaculture in Nigeria is based on the production of the African catfish. However, a high level of production and resilience within the aquaculture sector has been shown to be positively correlated with the culture of several species or species items. Thus, enhanced diversification of species and farming systems may boost aquaculture in Nigeria, as diversification of farming systems would allow optimum utilization of the abundant natural resources in the country. Many indigenous fish species that can be domesticated for culture have been identified. A great deal of scientific research and collaboration between major stakeholders, including the government, private industries, research institutions, and researchers, is required, so the production of these species can thrive like the already farmed catfish in Nigeria. As the successful domestication of any fish species takes a lot of time, effort, and resources, the species that have already proven to some extent to thrive in Nigeria, should be explored first. It is recommended that the best strategy for diversification of aquaculture for Nigeria is to increase the use of some already farmed species and the employment of a variety of production systems.

养殖鱼类品种多样化：增加尼日利亚水产养殖产量的一种手段

水产养殖生产了全球大约一半的鱼类消费量，是增长最快的食品部门。在非洲，鱼是动物蛋白的主要来源之一，尽管人们承认需要增加养殖鱼的产量来弥补捕捞渔业的下降，但该大陆在水产养殖方面的努力并未取得相称的成果。尼日利亚水产养殖的成功是基于非洲鲶鱼的生产。然而，水产养殖部门的高水平生产和复原力已被证明与几个物种或物种项目的养殖呈正相关。因此，加强物种和农业系统的多样化可能会促进尼日利亚的水产养殖，因为农业系统的多样化将使该国丰富的自然资源得到最佳利用。已经确定了许多可以驯化用于养殖的本地鱼类。包括政府、私营企业、研究机构和研究人员在内的主要利益相关者之间需要进行大量的科学研究和合作，因此这些物种的生产可以像尼日利亚已经养殖的鲶鱼一样茁壮成长。由于任何鱼类的成功驯化都需要大量的时间、精力和资源，因此应该首先探索已经在某种程度上证明在尼日利亚茁壮成长的物种。
