The round goby is a euryhaline bottom-dwelling species of fish of the family Gobiidae. It is native to Central Eurasia, including the Black Sea and the Caspian Sea. Round gobies have established large non-native populations in the Baltic Sea, several major Eurasian rivers, and the North American Great Lakes.
The common logperch, sometimes simply known as the logperch, is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. Like other logperches, it has the typical vertical barring along the flank and a subterminal mouth.
Mesogobius is a genus of Gobiidae, native to the basins of the Black and Caspian Seas.
The monkey goby is a species of goby native to the basins of the Black Sea and the Sea of Azov.
The racer goby is a species of goby native to fresh, sometimes brackish, waters, of the Black Sea basin. It is a Ponto-Caspian relict species. The species is placed a monotypic genus, Babka, which was once considered a subgenus of genus Neogobius, but was then elevated to genus-status based on the molecular analysis.
Ponticola kessleri, the bighead goby or Kessler's goby, is a species of goby native to Eurasia. The bighead goby is a Ponto-Caspian relict species. It inhabits the fresh and oligohaline waters, with mineralisation from 0-0.5‰ up to 1.5-3.0‰.
Lake Sapanca is a fresh water lake in Turkey, between the Gulf of İzmit and the Adapazarı Meadow. The lake has a catchment area of 251 km2, surface area is 45 km2, a length 16 km east–west / 5 km north–south, and a maximum depth of 52 m. Lake Sapanca, Turkey
The western tubenose goby is a species of goby native to fresh waters of the Black Sea and Aegean Sea basins. It has recently spread as an invasive species to Central and Western Europe and to North America. Previously Proterorhinus semilunaris was considered as a junior synonym of Proterorhinus marmoratus, but was confirmed as a distinct species based on molecular analysis.
Ponticola is a genus of gobies native mostly to fresh waters of the Black Sea - Caspian Sea region in Eurasia. Some species occur in the brackish-water Black and Caspian seas themselves. It was considered to be part of the broader goby subfamily Benthophilinae, also endemic to the same region, although the 5th edition of Fishes of the World does not list any subfamilies in the Gobiidae. Originally, Ponticola was described as subgenus of Neogobius.
The tadpole-gobies (Benthophilus), also called pugolovkas, are a genus of Ponto-Caspian fishes in the family Gobiidae.
Proterorhinus is a genus of fishes, known as the tubenose gobies. These gobiid fish are native to Eurasia where they occur in the region of the Caspian and Black seas, inhabiting marine, brackish and fresh waters. The species Proterorhinus semilunaris was introduced to the St. Clair River in Michigan during the late 1990s. Until recently, the genus was considered monotypic, comprising only the tubenose goby. Following molecular and further morphological investigations it has been split into several taxa, with distinct distributions in marine vs. fresh waters and in the Black Sea vs. Caspian Sea basins.
The Caspian goby is a species of fish endemic to the Caspian Sea where it is only found in brackish waters. It is the largest of the Caspian gobies, and at maximum may reach a length of 34.5 centimetres (13.6 in).
The Benthophilinae are a subfamily of gobies endemic to the Ponto-Caspian region. The subfamily includes about 50 species. The representatives of the subfamily have fused pelvic fins and elongated dorsal and anal fins. They are distinguished from the closely related subfamily Gobiinae by the absence of a swimbladder in adults and location of the uppermost rays of the pectoral fins within the fin membrane.
Khadzhibey Estuary, or Khadzhibeyskyi Liman, is an estuary of the north-western part of the Black Sea, located on the north-west from the City of Odesa. It is named after the former Khadzhibey fortress.
Neogobius pallasi, the Caspian sand goby or the Caspian monkey goby, is a species of fish native to fresh and brackish waters of the Caspian Sea basin including the Volga drainage up to the vicinity of Moscow. It has been introduced into the Aral basin. This species of goby can reach a length of 20 centimetres (7.9 in) SL. It is also important to local commercial fisheries.
Neogobius bathybius is a species of goby endemic to the Caspian Sea, where it occurs in depths down to 200 metres (660 ft). It is strictly confined to the brackish-water basin and does not enter fresh waters. It can grow up to a length of 25 centimetres (9.8 in) TL.
Sand goby may refer to several species of fishes of Gobioidei:
Holostephanus cobitidis is a species of parasitic trematode in the family Cyathocotylidae.
