Pinirampus pirinampu is a species of catfish (order Siluriformes) of the family Pimelodidae. P. pirinampu is also known as the flatwhiskered catfish. [8]

Taxonomy

This species was first described as Pimelodus barbancho; however, this is considered a nomen oblitum . [2] It was then described as Pimelodus pirinampu in 1829. In 1858, the genus Pinirampus was described for this species, in which it is usually classified as the only species. [2] [9] However, Megalonema argentinum has sometimes been considered a part of this genus. [10]

Distribution

This species is found in the Amazon, Essequibo, Orinoco, and Paraná basins. [8]

Description

P. pirinampu may reach a length of 60–75 centimetres (24–30 in) and an average weight of 3–5 kilograms (6.6–11.0 lb). [11] This species has a maximum published weight of 7.68 kg (16.93 lb). [8] These fish reach sexual maturity at just under 60 cm (24 in) in length. [12]

Ecology

P. pirinampu occurs in schools. [8] These catfish feed on benthic animals; they are nonspecialist feeders preying upon fish such as Iheringichthys labrosus and piranha Serrasalmus sp. . [8] [11] In the Amazon basin, these fish are preyed upon by Zungaro zungaro . [11] These fish are known from temperatures ranging from 24 to 29 °C (75 to 84 °F), pH range of 6 to 8, and an alkalinity range of 42 to 142 mEq/L. [8]

P. pirinampu is a species of migratory catfish. These fish gather in schools in the dry season to swim upstream to the headwaters, where they spawn at the onset of the rainy season in February. After spawning, the adults and juveniles drift downstream, reaching flooded areas or reservoirs used as foraging, growth sites and shelter against predation. [12] [11]

Relationship to humans

P. pirinampu is important for the fishery yield in Amazonas, Mato Grosso, Mato Grosso do Sul, Paraná, and Roraima states. [11] This species is included in the fishery statistics on the Paraguay River basin. [12] Brazil's Mato Grosso do Sul state government has adopted the criterion of 60 cm (24 in) TL minimum capture size for P. pirinampu. [12] P. pirinampu is an attractive fish for both leisure and professional sport fishers due to its tasteful meat and its fighting behavior. [11]

This species is one of the top ten dominant species in professional landings in the Itaipu reservoir of the Paraná river, where it is captured with longlines and cast nets in the upper half of the reservoir. [11] This species is also among the most important fishery resources in the Eng Souza Dias (Jupiá) Reservoir in the Upper Paraná river and the Águas Vermelhas reservoir in the Grande River.

<i>Pseudoplatystoma</i> Genus of fishes

Pseudoplatystoma is a genus of several South American catfish species of family Pimelodidae. The species are known by a number of different common names. They typically inhabit major rivers where they prefer the main channels and tend to stay at maximum depth, but some species can also be seen in lakes, flooded forests, and other freshwater habitats. They have robust bodies, and are important food fish. Recently, their population size has been on the drastic decline due to a variety of factors including overfishing and habitat destruction due to the construction of hydroelectric dams.

<i>Trichomycterus</i> Genus of fishes

Trichomycterus is a genus of fish in the family Trichomycteridae, the largest genus of its family with over 170 species currently described. This genus is native to freshwater habitats in Central and South America. These fish are generally small, usually about 5 to 15 cm (2–6 in) in standard length, although the largest, T. rivulatus, can reach more than twice this size. Species differ from one another primarily in body proportions, fin ray counts and colouration. Despite their relatively small size, some, such as T. punctulatus, support fisheries and are important in the local cuisine.

<i>Sorubim</i> Genus of fishes

Sorubim is a small genus of long-whiskered catfish native to tropical South America. A number of characteristics allows the differentiation of each species in the genus. Sorubim species are important food fish in South America and are highly significant to fisheries of some areas; however, harvests of these fish are not identified as much as other, more popular food fishes such as Colossoma, Arapaima, and Brachyplatystoma. Some species of this family are popular aquarium fish.

<i>Brachyplatystoma</i> Genus of fishes

Brachyplatystoma is a genus of catfish from the family Pimelodidae. As the occasionally used common name goliath catfishes indicates, this genus includes some of the largest species of catfish, including the piraíba, B. filamentosum, which reaches up to the region of 3.6 metres (12 ft) in length. Brachyplatystoma are found in the Amazon and Orinoco basins, and other tropical freshwater and brackish habitats in South America. Some species are migratory. These fish are important as food fish and, to some extent, aquarium fish.

This species is native to the Amazon and Orinoco River basins of Brazil, Colombia, Peru and Venezuela. Exallodontus is classified under the "Calophysus-Pimelodus clade". Within this clade, it is considered a part of the "Pimelodus-group" of Pimelodids, which also includes Pimelodus, Duopalatinus, Cheirocerus, Iheringichthys, Bergiaria, BagropsisParapimelodus, Platysilurus, Platystomatichthys, and Propimelodus.
