Eleginus Nawaga
The navaga (''Eleginus nawaga'') is a relatively small species of fish in the cod family Gadidae. It inhabits the European arctic and subarctic waters of the Barents, White, and Kara seas, from the Kola Bay to the Ob River estuary. Navaga fish usually occur at shallow depths, along shores with soft bottoms, close to the ice and on the continental shelf. In winter, they live in nearshore waters, where spawning takes place. They are often found in estuaries and can enter fresh water in rivers. In summer, they return to open waters. They feed on crustaceans, benthic animals, and small fish. They can grow to at least to 42 cm but typical adult size is smaller, being only 15–25 cm in the White Sea. The navaga is commercially fished mainly in the winter in the bays of the White Sea. The European navaga is a close relative of the saffron cod (''E. gracilis''), a Pacific The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends f ...

Eleginus Gracilis
The saffron cod ''(Eleginus gracilis)'' is a commercially harvested fish closely related to true cods (genus ''Gadus''). It is dark grey-green to brown, with spots on its sides and pale towards the belly. It may grow to 55 cm and weigh up to 1.3 kg. Its range spans the North Pacific, from the Yellow Sea and the Sea of Okhotsk in the west to the northern Gulf of Alaska and Sitka, Alaska, in the east. It also occurs in the Chukchi Sea (Arctic Ocean). It normally occurs in shallow coastal waters at less than 60 m depth but may also be found at depths up to 200 m. The saffron cod may also enter brackish and even fresh waters, occurring quite far up rivers and streams, but remaining within regions of tidal influence. Saffron cods begin to mature during their third year of life. They feed on fish and small crustaceans. They are commercially fished in many areas of the northwestern Pacific. The country with the largest catch is Russia Russia, or the Russian Federation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gadidae
The Gadidae are a family of marine fish, included in the order Gadiformes, known as the cods, codfishes, or true cods. It contains several commercially important fishes, including the cod, haddock, whiting, and pollock. Most gadid species are found in temperate waters of the Northern Hemisphere, but several range into subtropical, subarctic, and Arctic oceans, and a single ( southern blue whiting) is found in the Southern Hemisphere. They are generally medium-sized fish, and are distinguished by the presence of three dorsal fins on the back and two anal fins on the underside. Most species have barbels on their chins, which they use while browsing on the sea floor. Gadids are carnivorous, feeding on smaller fish and crustaceans. Gadids are highly prolific, producing several million eggs at each spawning. This contributes to their high population numbers, which, in turn, makes commercial fishing relatively easy. Concepts differ about the contents of the family Gadidae. The s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johann Julius Walbaum
Johann Julius Walbaum (30 June 1724 – 21 August 1799) was a German physician, natural history, naturalist and fauna taxonomist. Works Walbaum was from Greifswald. As an ichthyologist, he was the first to describe many previously unknown fish species from remote parts of the globe, such as the Barracuda, Great Barracuda (''Sphyraena barracuda''), the Chum salmon (''Oncorhynchus keta'') from the Kamchatka River in Siberia, and the curimatá-pacú (''Prochilodus marggravii'') from the São Francisco River in Brazil. Walbaum was one of the first to observe gloves as a preventative against infection in medical surgery. As early as 1767, he used gloves made from sheep intestines for vaginal exams. Legacy The Natural History Museum in Lübeck, opened in 1893, was based on Walbaum's extensive scientific collection. The museum's collection was, however, destroyed during the Bombing of Lübeck in World War II, Bombing of Lübeck. See also * References 18th-century German ...

Ray-finned Fish Genera
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class (biology), class of Osteichthyes, bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fish fin, fins made of webbings of skin supported by radially extended thin bony spine (zoology), spines called ''lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister taxon, sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation (anatomy), articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they domi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
