“…Of these, 16 species have been identified as endemic to the region, and another 29 are near endemic (Moffat and Linden 1995;Ebeku 2004). Common species in the delta include cat fish, tilapia, shell fish, fin fish, coroackers, barracuda, denticle herring and hingemouth (Eboh et al 2006;Oribhabor and Ansa 2006;Ekeke et al 2008). Other aquatic foods in the delta include crabs, barnacles, periwinkles and other aquatic invertebrates (World Bank 1995).…”

The Niger Delta wetlands are changing rapidly, raising concern for the wetlands' health and for communities relying upon its ecosystem services. Knowledge on ecosystem service provision is important for effective ecosystem and livelihoods management, but is currently lacking for the Niger Delta. We synthesised literature and used the 'Drivers-pressure-state-impact-response' (DPSIR) framework to structure information on changes in the wetlands' ecosystem services and implications for dependent communities. The wetlands' ecosystem services are being eroded through oil and gas exploration, dredging, invasive plant infestation and wetland reclamation. This is exacerbated by rising demand for oil, population growth and weak governance. Mass fish migration, water pollution and reduction of wetland area are also evident, impacting ecosystem services and traditional livelihood systems. This has caused poverty; people have to buy goods that previously could be obtained from the wetlands. Effective wetland management will be aided by: recognition of ecosystem services' contributions to community well-being; understanding how benefits are distributed over time, space, stakeholder; and how these changes in response to pressures. Since key pressures in the wetland are anthropogenic, understanding the role of institutions in relation to the Niger Delta's ecosystem services is imperative.

“…Pond water receives different organic substances (e.g., rice husk, rice and wheat grain, oil cake, cow dung, food waste, leaf litter, poultry litter, death fish body, livestock manure, domestic wastes, night soil, dried blood meal, death body of snail, vermicompost, etc. ); these organic substances are food supplements for fish (Oribhabor and Ansa 2006;Steinberg et al 2006;Chakrabarty, Das, and Das 2009). As result of different human activities, pond water also receives particulate matter, which starts to coagulate in water and settles on the bottom of the pond as sediment under gravitational force.…”

The effect of addition of roadside pond sediments on heavy metal contents of flooded rice paddies was studied to investigate the yield of rice and uptake of heavy metal by rice straw and grain. Sequential extraction of heavy metals on sediments shows that the percentage contribution of metals in the labile fraction follows the order lead (Pb, 48%) > copper (Cu, 42%) > zinc (Zn, 31%) > cadmium (Cd, 16%) > chromium (Cr, 9%) > nickel (Ni, 6%). The risk assessment code (RAC) for pond sediment revealed that Cr and Ni were found in the low-risk zone, Zn and Cd in the medium-risk zone, and Cu and Pb in the high-risk zone. However, though the heavy metal concentration in rice grain does not exceed the range acceptable for human consumption, it still represents a significant additional source of heavy metals in the diet. The addition of pond sediment significantly increased the rice yield over control. Therefore, pond sediment would be a valuable resource for agriculture if it is properly used.

“…The aquatic biodiversity of the Niger delta supports viable commercial fishery, employment and income to rural community dwellers (Davies et al, 2009). Some of the popular species found are the tilapia, barracuda, catfish, shellfish, denticle, herring, finfish, croakers, and hinge mouth (Oribhabor and Ansa, 2006;Eboh et al, 2006;Ekeke et al, 2008). Arimoro and Ikomi (2009) identified about 57 taxa of aquatic insects, some of which are edible and act as water quality bioindicators of Niger Delta.…”

The Niger Delta wetland ecosystem is of high economic importance to the local dwellers and the nation in general. The region is rich in both aquatic and terrestrial biodiversity and serves as a main source of livelihood for rural dwellers as well as stabilizing the ecosystem. Tremendous changes have occurred recently in the Niger Delta wetlands due to anthropogenic activities, thus raising awareness on the need for effective monitoring, protection and conservation of the wetland ecosystem. A good knowledge of the services provided by wetland ecosystems is an important key for an effective ecosystem management. The aim of this paper therefore was to review the importance of wetland resources, their threats and the need to protect them. This review shows that the region is rich in biodiversity of high economic importance to national development, and has been under severe threat from human activities, especially pollution. It is recommended that effective monitoring be employed using modern techniques such as GIS and remote sensing in the conservation and management of this important ecosystem.
