Saury
The saury (Cololabis adocetus) (not to be confused with the Pacific saury, another species in the genus Cololabis) is a member of the family Scomberesocidae, or the saury family. It is widespread in the Eastern Pacific in the surface waters, typically remaining in the top 50 centimeters of the water column - although it can be found at depths of up to 1 meter.[1] It can grow to a length of about 5 centimeters.[1] The saury generally lives in waters between 5 and 12 degrees Celsius.[1] The saury is a highly migratory fish

Cyprinus rubrofuscus
Cyprinus rubrofuscus, the Amur carp, is a species of cyprinid fish. It is widespread in Eastern Asia where native to Laos, Vietnam and China from the Amur to Red River drainages. It has also been introduced outside its native range.[1] It is the wild form of the well known koi. It is known for its muddy flavor and boniness, hence, it is not commonly eaten by locals except when stewed.

In the past it was considered a subspecies of the common (or European) carp, often under the scientific name C. carpio haematopterus (a synonym), but the two differ in genetics[3][4] and meristics, leading recent authorities to recognize them as separate species.[1][2] Although earlier studies also have found minor differences between northern ("haematopterus") and southern ("viridiviolaceus") populations in Eastern Asia in both meristics[5] and genetics,[3] later studies have found that they are not monophyletic.[6] However, any phylogenetic structure is difficult to establish because of widespread translocations of carps between different regions.[6] The parent species of the domesticated koi carp is an East Asian carp, possibly C. rubrofuscus (not C. carpio).

Atlantic saury
The Atlantic saury (Scomberesox saurus) is a fish of the family Scomberesocidae found in the Atlantic Ocean, in the seas near Australia, and also in the Mediterranean. The fish grow to about 35 cm in length, with a maximum of 50 cm, and have beaklike jaws and a row of finlets behind their dorsal and anal fins. Atlantic sauries live near the surface, and will often jump above the surface.

Australian prowfish
The Australian prowfishes form a family, Pataecidae, of scorpaeniform fishes. Australian prowfishes are distinguished by a long dorsal fin that begins far forward on the head, forming a "prow" shape, and extends all the way to the caudal fin. They lack scales and pelvic fins.

Parupeneus barberinoides
Parupeneus barberinoides, the bicolor goatfish, is a species of goatfish native to the western Pacific Ocean. An inhabitant of coral reefs, it can be found at depths of from 1 to 40 metres (3.3 to 131.2 ft). This species can reach a length of 30 centimetres (12 in) TL though most are only around 20 centimetres (7.9 in). This is a commercially important species and can also be found in the aquarium trade.

Hypopomidae
These fish originate from fresh water in Panama and South America.[1] The Hypopomidae are confined to the humid neotropics, ranging the Río de la Plata of Argentina (35°S) to the Río Tuira of Panama (8°N). Hypopomids are known from the continental waters of all South American countries except Chile, and are most diverse in the Amazon Basin.[2]

Bocaccio rockfish
The Bocaccio, Sebastes paucispinis, is a northeast Pacific species in the Sebastidae (rockfish) family. Other names for this species include salmon grouper, grouper, tom cod (juveniles), and slimy[citation needed]. In Greek, sebastes means “magnificent,” and paucispinis is Latin for “few spines”

Cutthroat trout
The cutthroat trout (Oncorhynchus clarkii) is a fish species of the family Salmonidae native to cold-water tributaries of the Pacific Ocean, Rocky Mountains, and Great Basin in North America. As a member of the genus Oncorhynchus, it is one of the Pacific trout, a group that includes the widely distributed rainbow trout. Cutthroat trout are popular gamefish, especially among anglers who enjoy fly fishing. The common name "cutthroat" refers to the distinctive red coloration on the underside of the lower jaw. The specific name clarkii was given to honor explorer William Clark, coleader of the Lewis and Clark Expedition.

Daggertooth pike conger
The dagger-tooth pike conger (Muraenesox cinereus) is a species of eel.[2] They primarily live on soft bottoms in marine and brackish waters down to a depth of 800 m (2,600 ft), but may enter freshwater.[2] They are common to about 1.5 m (4.9 ft) in length,[3] but may grow as long as 2.2 m (7.2 ft).[2] Dagger-tooth pike congers occur in the Red Sea, on the coast of the northern Indian Ocean, and in the West Pacific from Indochina to Japan. It has also invaded the Mediterranean through the Suez Canal.

Dolly Varden trout
The Dolly Varden trout (Salvelinus malma) is a species of salmonid native to cold-water tributaries of the Pacific Ocean in Asia and North America. It is in the genus Salvelinus of true chars, which includes 51 recognized species, the most prominent being the brook, lake and bull trout, as well as Arctic char. Although many populations are semi-anadromous, fluvial and lacustrine populations occur throughout its range. It is considered by taxonomists as part of the Salvelinus alpinus or Arctic char complex, as many populations of bull trout, Dolly Varden trout and Arctic char overlap.

Peters' elephantnose fish
Peters' elephant-nose fish (Gnathonemus petersii) is an African freshwater elephantfish in the genus Gnathonemus. Other names in English include elephantnose fish, long-nosed elephant fish, and Ubangi mormyrid, after the Ubangi River. As the Latin name petersii confirms it is named after someone called "Peters" (probably Wilhelm Peters), although the apostrophe is often misplaced and the common name given as "Peter's elephantnose fish". It uses electrolocation to find prey, and has the largest brain-to-body oxygen use ratio of all known vertebrates (around 0.6).
