Global demand for seaweed and its products has increased exponentially over the last 25 years. Equally, the continent of Africa and its offshore islands have considerable potential for seaweed production to contribute to world demand. Compared with China and the rest of Asia, Africa lags behind in seaweed production and utilisation. However, for red eucheumatoid seaweeds, Africa is the third-largest producer in the world, producing about 120,000 t (FW) annually. Details are provided for 13 African countries that are currently involved in seaweed farming and harvesting, commercially or experimentally, for export or domestic utilisation. Eucheuma spp. and Kappaphycus spp. in Tanzania represent 92% and in Madagascar 4.7% of continental production, and Ulva spp. and Gracilaria spp. in South Africa represent 1.5%. Over 2000 species of seaweed have been recorded in Africa, some of which are already successfully cultivated in other parts of the world. The environmental conditions across the continent range from warm, tropical waters to the cooler, nutrient-rich waters of the southwest, enabling the cultivation of seaweeds from the tropical, carrageenan-producing eucheumatoids to temperate kelp species. Seaweed aquaculture production in Africa, led predominantly by women, has improved the livelihoods of its coastal people. Challenges through disease and pest outbreaks, as a result of climate change, and the low prices paid to farmers are highlighted as major constraints on the development of this industry. Through scaling up and expanding current efforts in production and utilisation of seaweeds, Africa has the potential to join China and Southeast Asia as a global leader in producing, processing and consuming a wide variety of seaweeds.

“…Nigeria is endowed with about 79 species of seaweed, and the coastlines are characterized by sandy beaches and extensive mangroves, deltas, estuaries and lagoons with correspondingly low algal diversity [25]. Recent researches by Amosu et al [16], Fakoya et al [26] and Abowei and Tawari [27] have shown the potential of macroalgae resources for exploitation, culture and utilization for Nigeria, but as yet, no targeted commercial harvesting and cultivation has commenced. The cultivation methods of varies depend on the macroalgae species, which includes open water cultivation, land-based or semi-closed cultivation, pond cultivation, tank culture and raceways, spray cultivation systems.…”

This important marine resource has recently been emphasized due to the increasing demand for them as medicinal products, like anthelminthic, antibiotics, antifungal and antiviral, antitumour and antioxidant products, blocking and lowering of HIV/AIDS transmission and treatment of cancer patients [26,[33][34][35][36][37][38]. Seaweed can remove excess nutrients and major metallic pollutants from industrial and agricultural effluent, thus reducing coastal eutrophication [39,40].…”

Abstract:The cultivation of desirable aquatic organisms is becoming increasingly important as one of the fastest-growing agro-industrial activities in the world. Nigeria, over the years, practised traditional methods of aquaculture in tidal pools and floodplains of inland waters. Recently, the coastal region has been the focus of aquaculture development with introduction of cage culture system. Nigeria is one of the top aquaculture producers in Africa with numerous opportunities for large-scale production, and 80% of production is from small-scale farmers who involve in brackish and freshwater cultivation, except mariculture which has several setbacks. Nigeria is yet to show feasible interest in non-fed aquaculture (macroalgae) which is among the world's most efficient mass producer of proteins and other products. Constraints to production in the industry have been identified, while the prospects can be achieved by expanding aquaculture zones, enhancing management practices of production systems and improving product quality with the resultant creation of jobs, regular income and investment, etc.. This paper explores the status of aquaculture in Nigeria, and the components and the systems of commercial aquaculture were elucidated.
