Astatotilapia tweddlei is a species of fish in the family Cichlidae. It is found in Malawi and Mozambique. Its natural habitats are rivers and freshwater lakes.
This species was placed in the genus Astatotilapia by FishBase which while stating that the taxonomy is uncertain, Haplochromis is in their view restricted to the rivers and lakes of the drainage basin of Lake Victoria and they tentatively place this species in Astatotilapia. [2] The IUCN state that until further research is undertaken A. tweddlei should be regarded as restricted to Lakes Chilwa and Chiuta and their drainages, as well as probably through the drainage of the Ruvuma River. [1] The specific name honours the fisheries scientist Denis Tweddle of the Malawi Fisheries Research Unit. [3]
Copadichromis borleyi is a species of haplochromine cichlid fish endemic to Lake Malawi in East Africa. The species is popular in the fishkeeping hobby where it is frequently kept in aquariums. The species has numerous common names, including redfin hap and goldfin hap.
The dash-dot barb is a species of cyprinid fish.
Haplochromis welcommei is a threatened species of cichlid endemic to Lake Victoria in Africa. This species reaches a length of 10.5 centimetres (4.1 in) SL. Although further surveys are needed to confirm its status, it is considered possibly extinct by the IUCN on the basis that there have been no definite records since 1985.
Diplotaxodon ecclesi is a species of haplochromine cichlid. It is endemic to Lake Malawi where it is found in open water at mainly at the deeper levels, although it is rarely caught by trawling. Its main prey is the Lake Malawi sardine. The specific name honours the Senior Fisheries Research Officer of Malawi, David H. Eccles.
Haplochromis bartoni was a species of cichlid endemic to Lake Victoria. This species can reach a length of 19.5 centimetres (7.7 in) SL. It has not been recorded in recent surveys but as the whole of Lake Victoria has not ben surveyed for this species the IUCN classify it as Data Deficient. This species was said by Greenwood to bear some resemblance to Haplochromis worthingtoni so he named this species after E. Barton Worthington (1905-2001) as well.
Haplochromis bayoni is a species of cichlid endemic to Lake Victoria. This species reaches a length of 15.4 centimetres (6.1 in) SL. The specific name honours the Italian British physician and researcher into sleeping sickness Henry Peter Bayon (1876-1952).
Haplochromis brownae is a species of cichlid endemic to Lake Victoria though it may be extinct in the wild. This species can reach a length of 10.4 centimetres (4.1 in) SL. The identity of the person honoured by this species' specific name is not known but it is thought most likely to be Margaret “Peggy” Brown (1918-2009) who was a visiting scientist with the East African Freshwater Fisheries Research Organization at Jinja, Uganda in 1950 or 1951, where Humphry Greenwood was working.
Astatotilapia flaviijosephi, the Jordan mouthbrooder, is a vulnerable species of freshwater fish in the family Cichlidae (cichlids). It is found in the central Jordan River system, including Lake Tiberias (Kinneret), in Israel, Jordan and Syria, making it the only haplochromine cichlid to naturally range outside of Africa. This species is too small to be of significant importance to fisheries, unlike the only other cichlids native to the Levant, the economically important tilapias.
Haplochromis gilberti is a species of cichlid endemic to Lake Victoria. This species can reach a length of 15 centimetres (5.9 in) SL. The specific name honours Michael Gilbert who was the Experimental Fisheries Officer at the East African Freshwater Fisheries Research Organisation.
Haplochromis macconneli is a species of cichlid endemic to Lake Turkana, northern Kenya. This species can reach a length of 7.7 centimetres (3.0 in) SL. The specific name honours the Officer in Charge of the Fisheries Department at Lake Rudolf, R. B. McConnell, for the assistance he gave to the Lake Rudolf Research Project.
Haplochromis michaeli is a species of cichlid endemic to Lake Victoria though it may now be extinct. This species can reach a length of 14.5 centimetres (5.7 in) SL. The specific name honours the collector of the type, the British fisheries scientist Michael Graham (1888-1972).
Haplochromis pappenheimi is a species of cichlid found in the Democratic Republic of the Congo and Uganda where it occurs in Lake Edward, Lake George and the Kazinga Channel. This species can reach a length of 6.1 centimetres (2.4 in) SL. The specific name honours the curator of fishes at the Royal Museum, Berlin Paul Pappenheim (1878-1945), who was the co-author of the paper in which this species was described.
Haplochromis scheffersi is a species of cichlid endemic to Lake Kivu on the border of the Democratic Republic of the Congo and Rwanda. This species reaches a length of 8.5 centimetres (3.3 in) SL. The specific name of this species honours W. Scheffers who was the Director of the FAO Project for Fisheries Development at Lake Kivu when the authors were collecting at that lake.
Haplochromis schubotzi is a species of cichlid found in the Democratic Republic of the Congo and Uganda where it occurs in Lake George, Lake Edward and the Kazinga Channel. This species reaches a length of 12.5 centimetres (4.9 in) SL. Its specific name honours the German zoologist Johann G. Hermann Schubotz (1881-1955), who was a member of the Deutsche Zentral-Afrika Expedition of 1907–1908, on which he collected many specimens of fishes, amongst which was the type of this species.
Astatotilapia stappersii is a ray-finned fish species in the family Cichlidae. Adults measure about 15 cm (6 inches) in total length.
Nothobranchius kirki, the redfin notho, is a species of killifish from the family Nothobranchiidae which is endemic to Malawi where it occurs in the drainages of Lake Malawi and Lake Chilwa. It inhabits swamps and ephemeral pools. This species can reach a length of 5 centimetres (2.0 in) TL. It can also be found in the aquarium trade. This species was described in 1969 by the South African ichthyologist Rex Jubb from types collected by R. G. Kirk, who was a fish biologist of the Agricultural Research Services part of the Ministry of Natural Resources of Malawi, from a pool adjacent to the Likangala River which forms part of the endorheic basin of Lake Chilwa in Malawi.
Sciaenochromis fryeri is a species of cichlid endemic to Lake Malawi where it is found along the rocky coastal areas at depths of from 10 to 40 metres. It can reach a length of 11.5 centimetres (4.5 in) SL. The specific name honours Geoffrey Fryer (b.1927) who was Fisheries Research Officer, Joint Fisheries Research Organisation of Northern Rhodesia and Nyasaland.
Tilapia sparrmanii, the banded tilapia, or vlei kurper, is a widespread and adaptable cichlid fish that is found in warmer freshwater habitats of southern Africa. They prefer water with ample plant cover, and occur naturally as far north as DR Congo and Tanzania. They have been introduced locally in the northern hemisphere. Younger banded tilapia feed on crustaceans and insect larvae, while the adults feed on terrestrial and aquatic plants and other debris. They undertake local migrations and may shoal before and during spawning time. They guard their own eggs, and although they may move eggs or fry in the mouth, they are not known to be actual mouthbrooders like several other tilapia species. This species can reach a length of 23.5 centimetres (9.3 in) TL and is an important foodfish.
Haplochromis goldschmidti is a species of cichlid endemic to Lake Victoria, where it is only known to occur with certainty in the southern part of the Emin Pasha Gulf. It feeds mainly on zooplankton and some insects. This species can reach a length of 6.9 centimetres (2.7 in) SL. The specific name honours the Dutch evolutionary biologist Paul-Tijs (Tijs) Goldschmidt who he studied cichlids in Lake Victoria as a researcher from Leiden University.
Astatotilapia bloyeti is a species of haplochromine cichlid from the coastal river systems of Tanzania. Reports from other areas of Africa are considered to refer to related species. The IUCN considers it to be endemic to the Pangani River and includes Kenya in its range. This species taxonomic status is uncertain and some authorities place it in the genus Haplochromis while others retain it in Astatotilapia. This taxonomic uncertainty has led the IUCN to classify this species conservation status as Data Deficient. The specific name honours the collector of the type, Capitaine A. Bloyet, chief of the French research station at "Kandôa, Tanzania".
