This review covers aquaculture development in sub-Saharan Africa. The bulk of the production (93 percent) is from freshwater and is predominantly the culture of the indigenous and ubiquitous species of tilapias and African catfishes. In 2007 catfish contributed about 49 percent of the total production, and interest in the culture of the species for domestic markets, intra- and inter-regional trade and exports overseas is still growing in several countries.

The Asia-Pacific region continues to lead in aquaculture production. The dominance of the region in the global aquaculture scene is also exemplified by the Asia-Pacific being the leading producer of the major cultured commodities viz. finfish, molluscs, shrimp and seaweed, and nine out of ten of the current leading aquaculture-producing countries being from the region. Among the countries in the region, China has continued to maintain its dominance in aquaculture production.

This review covers aquaculture development in Europe. In Europe, aquaculture generally has a marginal contribution to national economies and employment. Extensive and semi-intensive systems employ more people per unit production than modern intensive systems. arming systems, technologies and species are very diverse in Europe. Significant research and development has focused on improving the efficiency of production systems and the quality of the produced fish, while mitigating environmental impact.

This review covers aquaculture development in Latin America and the Caribbean Region. Current norms and market conditions tend to discourage the participation of small-scale farmers in this industry, implying that there is a need for governmental help in providing technology and technical assistance to these producers including management, market and marketing, financial aspects, logistic, etc. that commonly become the soft spots that have made past support efforts fail for most part.

This review covers aquaculture development in the Near East and North Africa. The main driving forces responsible for the expansion of the sector have included an increased public health awareness and interest in fish products, the passing of enabling policies driven by the need for consolidating domestic fish supply, compensating for declining capture fishery landings, strengthening the livelihood of rural communities and supporting food security programmes.
