Mackerel is a common name applied to a number of different species of pelagic fish, mostly from the family Scombridae. They are found in both temperate and tropical seas, mostly living along the coast or offshore in the oceanic environment.
Herring are forage fish, mostly belonging to the family of Clupeidae.
The Gonostomatidae are a family of mesopelagic marine fish, commonly named bristlemouths, lightfishes, or anglemouths. It is a relatively small family, containing only eight known genera and 32 species. However, bristlemouths make up for their lack of diversity with relative abundance, numbering in the hundreds of trillions to quadrillions. The genus Cyclothone is thought to be one of the most abundant vertebrate genera in the world.
The viviparous brotulas form a family, the Bythitidae, of ophidiiform fishes. They are known as viviparous brotulas as they generally bear live young, although there are indications that some species do not. They are generally infrequently seen, somewhat tadpole-like in overall shape and mostly about 5–10 cm (2–4 in) in length, but some species grow far larger and may surpass 60 cm (2 ft).
The blue sucker is a long-lived freshwater species of fish in the sucker family that is of conservation concern. The species has an average weight of 2–3 kilograms (4.4–6.6 lb) and an average length of 76 centimetres (30 in). The record length has been recorded at 84 centimetres (33 in), and individuals have been documented beyond 40 years of age.
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.
Batasio is a genus of catfish of the family Bagridae. These small fish are found in fast-flowing hillstreams throughout South and mainland Southeast Asia.
Hyalobagrus is a genus of bagrid catfishes found in Southeast Asia.
Nemadoras elongatus is a species of thorny catfish native to the Amazon basin where it can be found in Brazil, Colombia and Peru. This species grows to a length of 12.7 centimetres (5.0 in) SL.
Fish are very diverse animals and can be categorised in many ways. Although most fish species have probably been discovered and described, about 250 new ones are still discovered every year. According to FishBase about 34,800 species of fish had been described as of February 2022, which is more than the combined total of all other vertebrate species: mammals, amphibians, reptiles and birds.
The Catostomidae are the suckers of the order Cypriniformes, with about 78 species in this family of freshwater fishes. The Catostomidae are almost exclusively native to North America. The only exceptions are Catostomus catostomus, found in both North America and Russia, and Myxocyprinus asiaticus found only in China. In the Ozarks they are a common food fish and a festival is held each year to celebrate them. The bigmouth buffalo, Ictiobus cyprinellus, can reach an age up to 127 years, making it the oldest known freshwater teleost by more than 50 years.
Several species of fish are claimed to produce hallucinogenic effects when consumed, a condition known as ichthyoallyeinotoxism. For example, Sarpa salpa, a species of sea bream referred to as the "dream-fish", is commonly claimed to be hallucinogenic. These widely distributed coastal fish are normally found in the Mediterranean and around the Iberian Peninsula, west to the Azores and along the west and south coasts of Africa. Occasionally they are found in British or more northerly waters. They may induce hallucinogenic effects similar to LSD if eaten. However, based on the reports of exposure they are more likely to resemble hallucinogenic effects of deliriants than the effects of serotonergic psychedelics such as LSD. In 2006, two men who apparently ate the fish experienced hallucinations lasting for several days. The likelihood of hallucinations depends on the season. Sarpa salpa is known as "the fish that makes dreams" in Arabic.
Carpiodes is a genus of suckers found in freshwater in North America.
Clinostomus is a genus of cyprinid fish that occur in eastern North America. There are two species in this genus.
Ochetobius elongatus is a species of cyprinid fish found in eastern Asia. It is the only member of its genus.
The tapertail, Radiicephalus elongatus, is a species of marine fish found in the central and eastern Atlantic and eastern Pacific. This species grows to 76 cm (30 in) in total length. It is the only known species in the genus Radiicephalus and the family Radiicephalidae.
Gnathopogon elongatus is a species of ray-finned fish in the genus Gnathopogon endemic to Japan.
