A tuna is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae (mackerel) family. The Thunnini comprise 17 species across five genera, the sizes of which vary greatly, ranging from the bullet tuna up to the Atlantic bluefin tuna, which averages 2 m (6.6 ft) and is believed to live up to 50 years.
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.
Catfish are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores, and even to a tiny parasitic species commonly called the candiru, Vandellia cirrhosa. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus Corydoras, are important in the aquarium hobby. Many catfish are nocturnal, but others are crepuscular or diurnal.
Herring are various species of forage fish, mostly belonging to the family of Clupeidae.
The Western Ghats, also known as the Sahyadri, is a mountain range that stretches 1,600 km (990 mi) along the western coast of the Indian peninsula. Covering an area of 160,000 km2 (62,000 sq mi), it traverses the states of Gujarat, Maharashtra, Goa, Karnataka, Kerala, and Tamil Nadu. The range forms an almost continuous chain of mountains along the western edge of the Deccan Plateau, from the Tapti River to Swamithoppe in Kanyakumari district at the southern tip of the Indian peninsula. The Western Ghats meet with the Eastern Ghats at Nilgiris before continuing south.
Sardine and pilchard are common names for various species of small, oily forage fish in the herring suborder Clupeoidei. The term 'sardine' was first used in English during the early 15th century; a somewhat dubious etymology says it comes from the Italian island of Sardinia, around which sardines were once supposedly abundant.
Needlefish or long toms are piscivorous fishes primarily associated with very shallow marine habitats or the surface of the open sea. Some genera include species found in marine, brackish, and freshwater environments, while a few genera are confined to freshwater rivers and streams, including Belonion, Potamorrhaphis, and Xenentodon. Needlefish closely resemble North American freshwater gars in being elongated and having long, narrow jaws filled with sharp teeth, and some species of needlefishes are referred to as gars or garfish despite being only distantly related to the true gars. In fact, the name "garfish" was originally used for the needlefish Belone belone in Europe and only later applied to the North American fishes by European settlers during the 18th century.
A fish is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology.
The African knifefish, Gymnarchus niloticus – also called the aba aba – is an electric fish, living at the bottoms of rivers and lakes. It is the only species in the genus Gymnarchus and the family Gymnarchidae, within the order Osteoglossiformes. It is a long slender fish with no pelvic or anal fins, and a tail fin shaped like a rat's tail. It swims using its elongated dorsal fin, allowing it to keep its body straight while it moves. This in turn enables it to produce a steady but weak electric field, which it uses to locate its prey. It is large for a river fish; adults can reach 1.6 m in length and 19 kg in weight.
The Pacific bluefin tuna is a predatory species of tuna found widely in the northern Pacific Ocean, but it is migratory and also recorded as a visitor to the south Pacific.
Triplophysa is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China, as well as inland waters of the larger part of central Asia. They can be distinguished from other genera of Nemacheilidae by marked sexual dimorphism, including the development of nuptial tubercles on breeding males. Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera, but as Wikipedia follows Fishbase for fish species all but Hedinichthys have been treated as subgenera in Wikipedia, although Kottelat in his revision of the loaches did recognise them as valid. FishBase, however, includes these in Triplophysa without specifying subgenera and treats the names given by Kottelat as synonyms.
An anchovy is a small, common forage fish of the family Engraulidae. Most species are found in marine waters, but several will enter brackish water, and some in South America are restricted to fresh water.
The Damsa Dam is a dam in Nevşehir, Turkey. Its development was backed by the Turkish State Hydraulic Works. It was built on the stream of the same name, for irrigation purposes. The dam is vitally important to the region, as it is a source of drinking water, and contains a large amount of fish species.
Troglonectes furcocaudalis is an oligotrobic species of stone loach. This cavefish is found only in Guangxi in China. It grows to 5.9 cm (2.3 in) standard length.
Troglonectes microphthalmus is a species of troglobitic stone loach. This cavefish is found only in Guangxi in China. It grows to 4.7 cm (1.9 in) standard length.
The Nemacheilidae, or stone loaches, are a family of cypriniform fishes that inhabit stream environments, mostly in Eurasia, with one genus, Afronemacheilus found in Africa. The family includes about 790 species.
Troglonectes is a genus of troglobitic fish in the family Nemacheilidae, native to caves of Asia. Fishbase and other authorities place these species in the genus Oreonectes.
William Neil Eschmeyer, also known as Bill Eschmeyer, is an American ichthyologist. He is the founder and developer of the database and reference work Catalog of Fishes, hosted by the California Academy of Sciences and available both on-line and in print.
