Iheringichthys is a small genus of long-whiskered catfish native to South America.

Contents

Species

There are currently three recognized species in this genus: [1] [2]

Distribution

All species of Iheringichthys are distributed in the Paraná River basin. [2] [3] [4]

Appearance and anatomy

Iheringichthys species have a narrow, small mouth positioned to point downwards. [5]

Ecology

I. labrosus has been studied to feed off of the bottom, mainly at dawn and during daytime hours. Main items in the diet of I. labrosus are aquatic insects (mainly Chironomidae) and mollusks (mainly Bivalvia). [5] Studies on I. labrosus demonstrates that this species is non-migratory and does not exhibit any parental care. [6] These fish reproduce all year, with spawning peaking from February to May. [6]

Relationship to humans

I. labrosus is a secondary commercial fish species in the Itaipu Reservoir. With the end of the trophic upsurge period in the Itaipu Reservoir, secondary species may become important resources for the commercial fishery, including I. labrosus. It is an important fish species in other reservoirs of the basin, especially Promissão and Água Vermelha Reservoirs. It is also an important sport fish in the sand beaches (“mandizeiros”) fishery along the upper Paraná River channel and main tributaries. [5]

<i>Hypostomus</i> Genus of fishes

Hypostomus is a genus of catfish in the family Loricariidae. They are native to tropical and subtropical South America. H. plecostomus is the popular freshwater aquarium fish formerly known as Plecostomus plecostomus. The taxonomic structure of the Loricariidae is still being expanded by scientists. Hypostomus is a highly species-rich and widely distributed catfish genus.

<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>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.

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.

Hisonotus is a genus of armored catfishes native to South America. Species of Hisonotus and Curculionichthys are the only representatives of the subfamily Otothyrinae having serrae on the posterior edge of the pectoral fin spine. These species are small fishes, generally found in small fast flowing streams, where they grasp to the branches and leaves of aquatic or subaquatic plants. The species of this genus mostly occur in Atlantic coastal streams of southern Brazil and the Paraguay-Paraná system of southern South America. They are also distributed in the Río de La Plata basin and coastal rivers of southeastern Brazil.

It grows to a standard length of 23 cm (9.1 in).
