Salmon is the common name for several commercially important species of euryhaline ray-finned fish from the family Salmonidae, which are native to tributaries of the North Atlantic and North Pacific basin. Other closely related fish in the same family include trout, char, grayling, whitefish, lenok and taimen.
A tuna is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae (mackerel) family. The Thunnini comprise 15 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.
Swordfish, also known as broadbills in some countries, are large, highly migratory predatory fish characterized by a long, flat, pointed bill. They are a popular sport fish of the billfish category, though elusive. Swordfish are elongated, round-bodied, and lose all teeth and scales by adulthood. These fish are found widely in tropical and temperate parts of the Atlantic, Pacific, and Indian Oceans, and can typically be found from near the surface to a depth of 550 m (1,800 ft), and exceptionally up to depths of 2,234 m. They commonly reach 3 m (10 ft) in length, and the maximum reported is 4.55 m in length and 650 kg (1,430 lb) in weight.
The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about 6,300,000 km2 (2,400,000 sq mi), or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela.
The Cyclopteridae are a family of marine fishes, commonly known as lumpsuckers or lumpfish, in the order Scorpaeniformes. They are found in the cold waters of the Arctic, North Atlantic, and North Pacific oceans. The greatest number of species are found in the North Pacific. The family name Cyclopteridae derives from the Greek words κύκλος (kyklos), meaning "circle", and πτέρυξ (pteryx), meaning "wing" or "fin", in reference to the circle-shaped pectoral fins of most of the fish in this family.
Squalidae, more commonly known as dogfish, dog sharks, or spiny dogfish, are one of several families of sharks categorized under Squaliformes, making it the second largest order of sharks, numbering 119 species across 7 families. Having earned their name after a group of fishermen reportedly observed the species chasing down smaller fish in dog-like packs, dogfish have slender, streamlined bodies, usually more compact in comparison to other species, and a pointed snout. Dogfish likewise have two dorsal fins, each with smooth spines, but no anal fin, and their skin is generally rough to the touch. As the species reaches adulthood, males usually measure a maximum of 100 cm, while females typically measure 125 cm long. The species therefore exhibits female-dominant sexual dimorphism.
The alewife is an anadromous species of herring found in North America. It is one of the "typical" North American shads, attributed to the subgenus Pomolobus of the genus Alosa. As an adult it is a marine species found in the northern West Atlantic Ocean, moving into estuaries before swimming upstream to breed in freshwater habitats, but some populations live entirely in fresh water. It is best known for its invasion of the Great Lakes by using the Welland Canal to bypass Niagara Falls. Here, its population surged, peaking between the 1950s and 1980s to the detriment of many native species of fish. In an effort to control them biologically, Pacific salmon were introduced, only partially successfully. As a marine fish, the alewife is a US National Marine Fisheries Service "Species of Concern".
The Pacific staghorn sculpin is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is found eastern Pacific Ocean. It is the only species in the monospecific genus Lepidocottus.
The common sole, Dover sole, or black sole is a species of flatfish in the family Soleidae. It is one of the largest fish in the Solea genus. It lives on the sandy or muddy seabed of the northern Atlantic and the Mediterranean Sea where it often semi-immerses itself in the substrate. The upper side is greyish-brown while the underside is white. It grows to a maximum length of about 70 cm (28 in). The species is prized as a food fish, being caught mostly by trawling on the seabed.
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 Atka mackerel is a mackerel in the family Hexagrammidae. Atka mackerel are common in the northern Pacific ocean, and are one of only two members of the genus Pleurogrammus - the other being the Arabesque greenling. The Atka mackerel was named for Atka Island, the largest island of the Andreanof islands, a branch of the Aleutians.
Artediellus is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. Most of the fishes in this genus are found in the northern Pacific Ocean but they also occur in the Arctic and North Atlantic Oceans.
Cyclopteropsis is a genus of marine ray-finned fishes belonging to the family Cyclopteridae, the lumpfishes or lumpsuckers. These small lumpfishes are found in the North Pacific and Arctic Oceans.
Gymnelus is a genus of small fish in the family Zoarcidae found in the Arctic Ocean, and adjacent parts of the North Pacific and North Atlantic. They are highly variable in color, which has resulted in the description of several taxa now considered invalid.
Cyclopteropsis bergi is a species of lumpfish native to the Northwest Pacific, where it is found at depths of 20 to 200 m. This species reaches 7 cm in total length and occurs in the Bering Sea, the Sea of Okhotsk, and the Sea of Japan where it may be found off of North Korea and Sado Island. In 2011, a single individual of the species was also reported from Sokcho, South Korea.
Cyclopteropsis brashnikowi is a species of lumpfish native to the Sea of Okhotsk and the Northwest Pacific off of the Kuril Islands, where it is found at a depth of 30 to 303 m. Adult individuals of the species have been noted to resemble the related species C. popovi, suggesting that the two species names may be synonymous. It is of disputed classification, being considered a species of Eumicrotremus by some authors, although sources such as FishBase, WoRMS, and ITIS do not follow this classification.
Cyclopteropsis inarmatus, also known as the bumpy lumpsucker, is a species of marine ray-finned fish belonging to the family Cyclopteridae, the lumpfishes or lumpsuckers. This fish is found in the North Pacific, where it occurs in the Bering Sea and the Sea of Okhotsk. In the Bering Sea, it can be found between Cape Navarin and Cape Olyutorskiy, whereas in the Sea of Okhotsk it is seen primarily off of the Kamchatka Peninsula. It inhabits a depth range of 76 to 150 m and reaches 6.4 cm in total length. It is a small demersal (bottom-dwelling) fish that may be seen in rocky areas.
Cyclopteropsis lindbergi is a species of lumpfish native to the Bering Sea, the Sea of Okhotsk, and the Sea of Japan. It is found at a depth range of 20 to 200 m, and it may reach 7 cm in total length.
Cyclopteropsis mcalpini, also known as the Arctic lumpsucker, is a species of lumpfish known only from the Arctic Ocean. It has been found in the Barents Sea and off the coast of northwestern Greenland, where it occurs at a depth range of 109 to 329 m. It is a small fish, growing to 7.5 cm in total length. Arctic lumpsuckers are reported to usually lay between 60 and 70 eggs, which are deposited in protected areas such as empty shells.
