- Additional Information
- The Niger River is a relatively "clear" river, carrying only a tenth as much sediment as the Nile because the Niger's headwaters lie in ancient rocks that provide little silt. Like the Nile, the Niger floods yearly; this begins in September, peaks in November, and finishes by May.
An unusual feature of the river is the Inner Niger Delta, which forms where its gradient suddenly decreases. The result is a region ofbraided streams, marshes, and lakes the size of Belgium; the seasonal floods make the Delta extremely productive for both fishing andagriculture.
The river loses nearly two-thirds of its potential flow in the Inner Delta between Ségou and Timbuktu to seepage and evaporation. All the water from the Bani River, which flows into the Delta at Mopti, does not compensate for the 'losses'. The average 'loss' is estimated at 31 km3/year, but varies considerably between years. The river is then joined by various tributaries, but also loses more water to evaporation. The quantity of water entering Nigeria measured in Yola was estimated at 25 km3/year before the 1980s and at 13.5 km3/year during the 1980s. The most important tributary of the Niger in Nigeria is the Benue River which merges with the river at Lokoja in Nigeria. The total volume of tributaries in Nigeria is six times higher than the inflow into Nigeria, with a flow near the mouth of the river standing at 177.0 km3/year before the 1980s and 147.3 km3/year during the 1980s.
The Niger Rİver Delta is rich on aquatic bimass and mostly fishes. lt is not as rich on species but stil during the dry season abundant fishes can be found (if the oil spill from recent times will not be repeated). The longnose elephant fishes as well as round nose species live here in large groups, none of the two are solitary fishes and should always be keept in groups. Also both live over sandy ground as they find their food in it (by digging with their “long” or “shortnose” deep into it). This behaviour is similar to taht Corydoras species in South America and of memebers of the Gymnotiformes. Predators live next to peaceful fishes very well and dwarf cichlids even their eggs-naturally garding and protecting these carefully.Habitat
An area North-west of Port Harcourt in Nigeria, blackwaters of the Niger River. Biotope: marmelstone along the shore almost cascade-like, fine sand, some drift wood. Aquatic plants of only few varieties shown here- in most areas plants they are completely absent. The pH averages between pH 5.8 and 6.8 the conductivity value from 32 to 65. The temperature varied from 25.5 – 28.5
