The Citharinidae, the lutefishes, are a small family of characiform fish. They are freshwater fish native to Africa, and are sufficiently abundant to be significant food fishes. [1]
They are deep-bodied, silvery fish, measuring up to 84 cm (33 in) in length and weighing up to 18 kg (40 lb). [2] They are filter feeders. [1]
The family contains three genera:
The Merlucciidae, commonly called merluccid hakes, are a family of cod-like fish, including most hakes. They are native to cold water in the Atlantic and Pacific Oceans, and typically are found at depths greater than 50 m (160 ft) in subtropical, temperate, sub-Arctic or sub-Antarctic regions.
Characiformes is an order of ray-finned fish, comprising the characins and their allies. Grouped in 18 recognized families, more than 2000 different species are described, including the well-known piranha and tetras.
Characidae, the characids or characins is a family of freshwater subtropical and tropical fish, belonging to the order Characiformes. The name "characins" is the historical one, but scientists today tend to prefer "characids" to reflect their status as a by and large monophyletic group at family rank. To arrive there, this family has undergone much systematic and taxonomic change. Among those fishes that remain in the Characidae for the time being are the tetras, comprising the very similar genera Hemigrammus and Hyphessobrycon, as well as a few related forms such as the cave and neon tetras. Fish of this family are important as food and also include popular aquarium fish species.
Aulopiformes is a diverse order of marine ray-finned fish consisting of some 15 extant and several prehistoric families with about 45 genera and over 230 species. The common names grinners, lizardfishes and allies, or aulopiforms are sometimes used for this group. The scientific name means "Aulopus-shaped", from Aulopus + the standard fish order suffix "-formes". It ultimately derives from Ancient Greek aulós + Latin forma, the former in reference to the elongated shape of many aulopiforms.
The Alert pigfish is a species of marine ray finned fish, a pigfish belonging to the family Congiopodidae. It is the only species in the monotypic genus Alertichthys. This species is endemic to the waters around New Zealand.
The wolf eel is a species of marine ray-finned fish belonging to the family Anarhichadidae, the wolf fishes. It is found in the North Pacific Ocean. Despite its common name and resemblance, it is not a true eel. It is the only species in the monotypic genus Anarrhichthys.
Alestes stuhlmannii is a species of fish in the family Alestidae. It is endemic to the Ulanga River in Morogoro Region of Tanzania.
Max Fernand Leon Poll was a Belgian ichthyologist who specialised in the Cichlidae. In the years 1946 and 1947 he organised an expedition to Lake Tanganyika.
The piper gurnard, also known as the piper or the lyre gurnard, is a species of marine, demersal ray-finned fish from the family Triglidae, the gurnards and sea robins. It is found in the eastern Atlantic Ocean and the Mediterranean Sea. It is the only species in the monotypic genus Trigla.
Ladigesia roloffi, the Sierra Leone dwarf characin, is a species of African tetra that is found in Sierra Leone and Liberia. It is the only member of its genus.
Klausewitzia ritae is a species of South American darter found in the upper Amazon River basin at the Peruvian/Brazilian border. It is the only member of its genus.
Channichthys is a genus of marine ray-finned fish belonging to the family Channichthyidae, the crocodile icefishes. They are native to the Southern Ocean.

This species reaches a length of 7.0 cm (2.8 in).
Nannopetersius lamberti is a species of fish in the African tetra family, found in the African river basins of the Ntem, the Ogowe, the Nyanga and the Kouilou Rivers. This species reaches a length of 7.0 cm (2.8 in).
Nannopetersius mutambuei is a species of fish in the African tetra family, only found in the Inkisi River upstream of the Sanga dam in the lower Congo River basin, in the Democratic Republic of the Congo. This species reaches a length of 12.0 cm (4.7 in).
Alestopetersius brichardi is a species of African tetras found in the Malebo Pool, the middle Congo River, the Ruki River drainage and the Lomami River in the Democratic Republic of the Congo. This species reaches a length of 7.9 cm (3.1 in).

It is known only from a small tributary of the Bari River in the Lua River system in the Ubangi River drainage, in the middle Congo River basin in the Democratic Republic of the Congo. This species reaches a length of 6.3 cm (2.5 in).
