SwordfishThu, Feb 18, 2021 7:29 PM
Swordfish (Xiphias gladius; from Greek ξίφος: sword, and Latin gladius: sword), are large, highly migratory, predatory fish characterized by a long, flat 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.
They are the sole member of their family, Xiphiidae. Females are larger than males, and Pacific swordfish reach a greater size than northwest Atlantic and Mediterranean swordfish. They reach maturity at 4–5 years of age and the maximum age is believed to be at least 9 years. The oldest swordfish found in a recent study were a 16-year-old female and 12-year-old male. Swordfish ages are derived, with difficulty, from annual rings on fin rays rather than otoliths, since their otoliths are small in size.
Swordfish prefer water temperatures between 18 an
Arctic CharMon, Jul 18, 2022 2:32 PM
Arctic char is a cold-water fish in the family Salmonidae, native to alpine lakes and arctic and subarctic coastal waters. It breeds in fresh water, and populations can either be landlocked or anadromous, migrating to the sea. No other freshwater fish is found as far north; it is, for instance, the only fish species in Lake Hazen on Ellesmere Island in the Canadian Arctic. It is one of the rarest fish species in Britain, found only in deep, cold, glacial lakes. In other parts of its range, such as Scandinavia, it is much more common, and is fished extensively. It is also common in the Alps, (particularly in Trentino and the mountainous part of Lombardy), where it can be found in lakes up to an altitude of 2,600 m (8,500 ft) above sea level, and in Iceland. In Siberia, it is known as golets and it has been introduced in lakes where it sometimes threatens less hardy endemic species, such as the small-mouth char and the long-finned char in Elgygytgyn Lake. The Arctic char is closely re
Sockeye SalmonSat, Mar 14, 2015 6:47 PM
Sockeye salmon is an anadromous species of salmon found in the Northern Pacific Ocean and rivers discharging into it. This species is a Pacific salmon that is primarily red in hue during spawning. They can be up to 84 cm in length and weigh anywhere from 2.3 to 7 kg. Juveniles remain in freshwater until they are ready to migrate to the ocean, over distances of up to 1,600 km. Their diet consists primarily of zooplankton. Sockeye salmon are semelparous, dying after they spawn. Some populations, referred to as kokanee, do not migrate to the ocean and live their entire lives in freshwater.
Sockeye salmon is the third most common Pacific salmon species, after pink and chum salmon. Oncorhynchus comes from the Greek '-ychos' meaning nail, and 'rhyngchos' meaning snout. nerka is the Russian name for the anadromous form. The name "sockeye" is an anglicization of suk-kegh (sθə́qəy̓), its name in Halkomelem, the language of the indigenous peop
Blueline TilefishThu, Sep 23, 2021 10:21 AM
The blueline tilefish is a dull olive-gray overall and white below. The lack of fleshy protuberance behind the head distiguishes it from the commercially important tilefish, Lopholatilus chamaeleonticeps. Elongate, continuous dorsal and anal fins more than half the length of body, long snout, narrow gold stripe underlined in blue from snout to tip of eye. Strong, flat spine on gill cover. The blueline tilefish is a bottom dweller found in water ranging from 240-780 feet deep, from Virginia to the Campeche Banks of Mexico. It is frequently found in the same habitat as groupers and snappers, preffering irregular bottom with sand, mud and shell hash. It is usually found in bottom water temperatures of 59° to 73° F. It has been found to burrow head first in cone-shaped sand piles. It may grow to be 32 inches and live up to 15 years. Spawning occurs from May to October, and females may lay more than 4 million free-floating eggs (Hermaphrodism is suspected to occur in this
Black DrumTue, Oct 28, 2014 12:27 PM
The black drum (Pogonias cromis) is a saltwater fish similar to its cousin, the red drum. It is the only species in the genus Pogonias. Though most specimens are generally found in the 5-30 lb (2–14 kg) range, the black drum is well known as the largest of all the drum family with some specimens reaching excesses of 90 lbs (40 kg). The world record black drum was just over 113 lbs (51 kg). They are often black and/or gray in color with juvenile fish having distinctive dark stripes over a gray body. Their teeth are rounded and they have powerful jaws capable of crushing oysters and other shellfish. It is recommended those over 15 lbs pounds (7 kg) should be released. Black drum are capable of producing tones between 100 Hz and 500 Hz when performing mating calls. The black drum is usually found in or near brackish waters. Larger, older fish are more commonly found in the saltier areas of an estuary (closer to the ocean) near oyster beds or other plentiful food sources. Juveni
WeakfishFri, Dec 25, 2020 10:45 PM
The weakfish, Cynoscion regalis, is a marine fish of the drum family Sciaenidae. A large, slender, marine fish, it is found along the east coast of North America. The head and back of this fish are dark brown in color with a greenish tinge. The sides have a faint silvery hue with dusky specks, and the belly is white. The origin of its name is based on the weakness of the mouth muscles, which often cause a hook to tear free, allowing the fish to escape. The weakfish grows to 1 m (3 feet) in length and 9 kg (20 pounds) in weight. It is found along the eastern coast of North America from Nova Scotia, Canada to northern Florida, where it is fished both commercially and recreationally. Weakfish are also known by the American Indian name "Squeteague". In the mid-Atlantic states, the fish is sometimes referred to by the name sea trout, though it is not related to the fishes properly called trout, which are in the family Salmonidae. The weakfish is the state fish of Dela
Yellow PerchSat, Jan 23, 2016 9:59 PM
The yellow perch (Perca flavescens), commonly referred to as perch, is a freshwater perciform fish native to much of North America. Other common names for yellow perch include American perch, coontail, lake perch, raccoon perch, ring-tail perch, ringed perch, and striped perch. Yellow perch is often recognized by its dark vertical stripes and gold or yellow body color. Perca is derived from early Greek for "perch" and flavescens is Latin for "becoming gold" or "yellow colored". Adult sizes typically range from 3.9–11.4 in (10–30 cm); though have been known to grow larger. The yellow perch has a laterally compressed body with an oval, oblong shape. The anal fins are a green or yellow-orange, the dorsal fin is an olive color, and the belly is cream-colored. The vertical bands fade as they near the belly. Spawning intensifies the bands in males, and they can be nonexistent in juveniles. The spiny anterior dorsal fin has 13 to 15 spines. T
WalleyeFri, May 26, 2023 2:48 PM
Walleye (Sander vitreus, formerly Stizostedion vitreum) is a freshwater perciform fish native to most of Canada and to the Northern United States. It is a North American close relative of the European pikeperch. The walleye is sometimes called the yellow walleye to distinguish it from the blue walleye, which is a subspecies that can be found in the southern Ontario and Quebec regions. In some parts of its range, the walleye is known as the walleyed pike, colored pike, yellow pike or pickerel (esp. in English-speaking Canada), although the fish is not related to other species of pikes which are members of the family Esocidae. Walleyes show a fair amount of variation across watersheds. In general, fish within a watershed are quite similar and are genetically distinct from those of nearby watersheds. The species has been artificially propagated for over a century and has been planted on top of existing populations or introduced into waters naturally devoid of the species, sometimes re
Skipjack TunaMon, Oct 27, 2014 12:46 AM
The skipjack tuna, Katsuwonus pelamis, is a medium-sized perciform fish in the tuna family, Scombridae. It is otherwise known as the aku, arctic bonito, mushmouth, oceanic bonito, striped tuna, or victor fish. It grows up to 1 m (3 ft) in length. It is a cosmopolitan pelagic fish found in tropical and warm-temperate waters. It is a very important species for fisheries. It is a streamlined, fast-swimming pelagic fish, common in tropical waters throughout the world, where it inhabits surface waters in large shoals (up to 50,000 fish), feeding on fish, crustaceans, cephalopods, and molluscs. It is an important prey species for large pelagic fishes and sharks. It has no scales, except on the lateral line and the corselet (a band of large, thick scales forming a circle around the body behind the head). It commonly reaches fork lengths up to 80 cm (31 in) and a weight of 8–10 kg (18–22 lb). Its maximum fork length is 108 cm (43 in) and maximum weight is 34.5 kg (76 lb).
Great BarracudaMon, Oct 27, 2014 12:07 AM
The great barracuda (Sphyraena barracuda) also known as the giant barracuda, is a species of barracuda. Great barracudas often grow over 6 feet (1.8 m) long and are a type of ray-finned fish. Great barracudas are large fish. Mature specimens are usually around 60–100 cm (24–39 in) in length and weigh 2.5–9.0 kg (5.5–19.8 lb). Exceptionally large specimens can exceed 1.5 m (4.9 ft) and weigh over 23 kg (51 lb). The record-sized specimen caught on rod-and-reel weighed 46.72 kg (103.0 lb) and measured 1.7 m (5.6 ft), while an even bigger specimen measured 2 m (6.6 ft) and weighed 50 kg (110 lb).Barracudas are elongated fish with powerful jaws. The lower jaw of the large mouth juts out beyond the upper. Barracudas possess strong, fang-like teeth that are unequal in size and set in sockets in the jaws and on the roof of the mouth. The head is quite large and is pointed and pike-like in appearance. The gill covers do not have spines and are covered wi
PikeTue, May 25, 2021 11:29 AM
The northern pike (Esox lucius), known simply as a pike in Britain, Ireland, most of Canada, and most parts of the USA, (also called jackfish or simply "northern" in the Upper Midwest of the USA and in Manitoba, Canada), is a species of carnivorous fish of the genus Esox (the pikes). They are typical of brackish and fresh waters of the Northern Hemisphere (i.e. holarctic in distribution). Pike grow to a relatively large size: the average length is about 70–120 cm (28–47 in). Even so, lengths of up to 150 cm (59 in) and weights of 25 kg (55 lb) are very rare.
Northern pike are most often olive green, shading from yellow to white along the belly. The flank is marked with short, light bar-like spots and a few to many dark spots on the fins. Sometimes, the fins are reddish. Younger pike have yellow stripes along a green body; later, the stripes divide into light spots and the body turns from green to olive green. The lower ha

Menticirrhus americanus, the southern kingfish, southern kingcroaker, the king whiting, the Carolina whiting, or the Sea Mullet, is a species of marine fish in the family Sciaenidae. It lives in shallow coastal waters on the western fringes of the Atlantic Ocean.
The southern kingcroaker can grow to about 50 centimetres (20 in) but a more usual adult length is 30 centimetres (12 in). The southern kingcroaker is a slender fish, deepest about two fifths of the way along. The upper jaw projects further than the lower and the snout overhangs the mouth. There is a small barbel on the fleshy lower lip. The dorsal fin is divided into two parts. The number of spines and soft rays in the fins is indicative of the species and in M. americanus, the front part of the dorsal fin is broadly triangular and has 10 spines and the other part is long and has 1 spine and 22 to 25 soft rays. The pointed pectoral fins are large and the anal fin has 1 spine and 7 or 8 soft rays. The tail fin has a charac
