The firewood catfish (Sorubimichthys planiceps) a species of South American pimelodid catfish, is the sole member of the genus Sorubimichthys. [3] Firewood catfish are one of the hundreds of freshwater fish in the Amazon Basin that play important ecological and economic roles. [4] Known by locals along the Amazon Basin as peixe-lenha, [5] the firewood catfish is so called because it is of little eating value and is often dried and used for firewood. [6] Firewood catfish are imported to areas outside their native range as in-demand aquarium fish. [7]

Contents

Distribution and habitat

The firewood catfish occurs in the Amazon Basin, a tropical area which exhibits the greatest diversity of fish species in the world, [8] and in the Orinoco Basin, another tropical habitat rich in rivers, floodplains, and wetlands. [9] It is normally found in whitewater high in suspended sediments. [10] Firewood catfish have been introduced to areas outside of their native range, including Lake Superior through live trade in 2005 [11] and the San Francisco Bay via aquarium release in 2019. [7] Both of these introductions were unsuccessful. The full extent of their occurrence outside of their native distribution as well as the impact on other species of introductions outside of their native ranges are unknown or undocumented, due to a lack of research analyzing their potential effects on non-native ecosystems. [7]

Appearance and anatomy

The largest recorded specimen of adult firewood catfish was reported at 1500 mm (4.9ft) in standard length (a measurement from the tip of the snout to the posterior end of the last vertebrae). [7] Juveniles have been measured ranging from 10–39 mm, and other adult specimens have been measured ranging from 209–475 mm. [13]

Juveniles have short snouts, rounded pectoral fins, and underdeveloped color patterns. [13] Standard adult and subadult appearance includes a flat head (the species name, planiceps, comes from the Latin for flathead or flat-headed) [14]  with a long upper jaw and a snout adorned by long barbels attached to the jawbone that provide them with sensory information that aids prey-seeking and navigation in deep, murky water. [15] The dorsum is ash-gray with darker spots. The sides have a white band, bordered below by a dark gray or brown band. The venter is usually white with some large spots. The dorsal fin and adipose fin are spotted, [13] and the anal fins are hyaline. They have long, large, deeply forked caudal fins. [13] Like most catfish, they have sharp dorsal and pectoral fins useful for predator defense and abrasive pads on the surface of their mouths. [16]

Ecology

Firewood catfish are demersal fish that live in freshwater environments with high temperatures, tropical climates, and dense vegetation. [13] Habitats they have been recorded in, such as the Mamoré River, [18] are characterized by meandering, silty rivers and expansive floodplains, capable of providing nurseries for species the firewood catfish predates upon. [7] Like most other members of Pimelodidae, the firewood catfish is a benthic fish. [16] This fish is mainly nocturnal. [19] Firewood catfish are highly predatory [10] and feed on nekton, primarily other fish. [10] As a result of their position at the top of aquatic food chains, many predatory catfish have frequently shown the highest mercury concentrations of measured fish in the Amazon Basin. [20] While not much research has been done on unique roles of the firewood catfish within their ecosystems, one study found that firewood catfish may host a tapeworm parasite described as "new to science". [21] [4]

Conservation

They have been listed as "vulnerable to extinction" in the Orinoco River basin due to habitat loss as a result of urbanization and development. [22] [23] Like many other fish species in South America, firewood catfish live in an area of significant concern due to the impacts of habitat loss, introduced exotic species, and overfishing, and have not been significantly researched with the intention of documenting their ecological roles. [23]

<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>Acanthicus</i> Genus of fishes

Acanthicus is a genus of large, South American suckermouth armored catfishes native to the Amazon and Orinoco basins, and possibly in Guyana. The name Acanthicus is derived from the Greek, akanthikos meaning thorny, spiny. Fish of this genus are known as lyre-tail plecos. These species are found in large rivers, primarily in areas with a rocky bottom and a moderate or strong current.

<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 3.6 metres (12 ft) in length; though the other species don't reach this length. Brachyplatystoma are found in the Amazon and Orinoco basins, and other tropical freshwater and brackish habitats in South America. Many species are migratory. These fish are important as food fish and, to some extent, aquarium fish.
