Bass, striped Morone saxatilis

Bass, striped Morone saxatilis
Walbaum, 1792

MORONIDAE FAMILY
Also called striper, rock, rockfish, squid hound, greenhead

The striped bass, or “rockfish” as it is known in North and South Carolina, occurs from the St. Lawrence River to northern Florida on the Atlantic coast of the United States; off Florida, Louisiana, Alabama and Mississippi in the Gulf of Mexico; and along the U.S. Pacific coast from Washington to California. Striped bass were unknown on the Pacific coast until they were introduced there in 1879 and 1882. On the east coast they have been well known to saltwater anglers and one of the most important food fishes since at least the early 1600's.

In saltwater, the striped bass is anadromous and migratory. Some migrate from North Carolina, Virginia, or Maryland to more northern climates in the summer and return when the summer season is over. Others remain non migratory within estuarine river systems such as the St. Lawrence, the Santee Cooper, or the Savannah. To most freshwater anglers, this very important game fish is relatively new. The species moves far upstream in rivers during spawning migrations. It has a native range (in freshwater) from the St. Lawrence River, N.Y., south to St. John's River, Florida, and also from the Suwannee River in Florida, to Lake Pontchartrain in Louisiana. In some of these waters populations have become landlocked due to artificial impoundments that blocked their return to the sea. In recent years, striped bass have been introduced into freshwater systems in most of the states.

The striped bass' closest freshwater relatives are the white bass (Morone chrysops), the yellow bass (M. mississippiensis), and the white “perch” (M. americana). The striped bass is easily recognized by the 7 or 8 prominent black stripes that run along the scale rows on each side of its long, sleek, silvery body. One stripe runs along the lateral line, and the remainder are about equally divided above and below it. The first dorsal fin has 8 10 spines and the second, 10 13 soft rays. The anal fin has 3 spines followed by 7 13 soft rays. The dorsal fins are completely separated. The striped bass is longer and sleeker and has a larger head than its close and similar looking relative, the white bass. The striped and white basses have been crossed to create a hybrid known as the whiterock or sunshine (in Florida) bass. Striped bass can be distinguished from hybrids by the regularity of stripes while the hybrid usually has interrupted or broken stripes.

A voracious and opportunistic predator, the striped bass will consume all types of fishes. A wide variety of fishing methods are successfully employed, including trolling, jigging, bait fishing, surf casting, fly fishing, and spinning. Baits and lures include mullet, squid, eels, crabs, clams, bloodworms, plugs, spoons, flies, and casting lures

Bass, rock Ambloplites rupestris

Rafinesque, 1817

CENTRARCHIDAE FAMILY
Also called black perch, goggle eye, red eye, rock sunfish

Native to the northeastern U.S.A. and southeastern Canada, from Ontario and Quebec southward through the Great Lakes region as far as Tennessee an possibly Alabama. Rock bass have also been introduced into other states including some western states. They prefer small, cool, weedy lakes and streams and the outer edges of larger lakes, always over rocky bottoms (hence the name “rock” bass) where no silt is present, turbidity is low and cover is extensive. They are scrappy fighters but tire quickly. The flesh is firm, white, and makes excellent eating.

This is a large and robust sunfish that looks like a cross between a bluegill and one of the black basses. Its body is less compressed than most sunfishes of the genus Lepomis, including the bluegill, and longer in profile. It has been known to reach 3 lb (1.36 kg) but the more common size is about 8 oz (226 g). There is a black spot at the edge of the gill cover. The mouth is larger and more “basslike” than in most small sunfishes, the upper jaw reaching beyond the beginning of the eye, but not to the back of the eye. The two dorsal fins are clearly connected. The eyes are red.

The rock bass is frequently confused with the warmouth (Lepomis gulosus), it can be distinguished by the number of spines in front of the soft rayed anal fin; 3 spines in the warmouth, but 6 in the rock bass. Also, the warmouth has teeth on the tongue unlike the rock bas

Mackerel, Pacific sierra Scomberomorus sierra

Mackerel, Pacific sierra Scomberomorus sierra
Jordan, Starks 1895

SCOMBRIDAE FAMILY
Also called carite sierra, serrucho, sierra

Occurs in the eastern central Pacific: from La Jolla in southern California, USA south to the Galapagos Islands and Paita, Peru and has been reported from Antofagasta, Chile.

The Pacific sierra is most easily distinguished by pigment and color pattern. It is silver-blue above and silvery white on the lower sides and belly with a series of yellow-brown spots on the sides. The anterior half of the first spiny part of the dorsal fin is jet black, in contrast to the lighter remainder of the fin.

A schooling species, the Pacific sierra is fast moving, voracious predator feeding on small fishes, especially anchovies and herrings. It occurs near the surface of coastal waters over the continental shelf and is believed to spawn close to the coast over most of its range.

The Pacific sierra is the most abundant game fish along the Pacific coasts of Mexico and Central America. Anglers employ a variety of natural baits and artificial lures with wire leaders to guard against their sharp teeth. (See also mackerel, cero and Spanish)

Shark, blue Prionace glauca

Shark, blue Prionace glauca
Linnaeus, 1758

CARCHARHINIDAE FAMILY
Also called blue whaler, great blue shark, bluedog

Inhabits cool temperate seas, often near the surface, but usually submerged to depths of 110 to 170 fathoms in the tropics or in areas with warm water currents, 50°-68°F (10°- 20°C). It is usually replaced as the common large pelagic shark by the white tip in areas of warm surface water. It is present in the Mediterranean, absent from the Baltic and Red Seas, and extremely rare in the Gulf of Mexico.

It is recognizable by its brilliant blue color. It is dark cobalt or indigo blue dorsally, lightening to bright blue on the flanks and white on the belly. It is unique among sharks in that the larger teeth of the upper jaw are “saber shaped”, with one margin broadly convex, the other concave. The teeth are serrated along the edges. Those in the lower jaw are narrower and very sharp. Caudal keels and spiracles are absent.

They are pelagic, migratory and travel alone as well as in packs. Fishes, sea birds, squid and other sharks are prey to the blue shark. While not considered one of the most dangerous sharks, they have been implicated in unprovoked attacks on both humans and boats.

Fishing methods include chumming with live or dead baits or trolling. Baits include squid, eels, mackerel, herring and other live, whole fishes or cut baits.

The blue shark is viviparous, giving birth to 50 or more young at a time. It does not rate high as table fare

Dentex Dentex dentex

Dentex Dentex dentex
Linnaeus, 1758

SPARIDAE FAMILY
Also called dentice, denton, or dente)

Occurs in the Mediterranean and Atlantic Ocean from the Bay of Biscay to West Africa north off Cape Blanc and Madeira. Occasionally, dentex are found as far north as the British Isles and as far south as Senegal.

While inhabiting hard bottoms (rock or rubble) down to 200 m (656 ft), dentex are more commonly found between 15 and 50 m (50 and 165 ft). Adults are generally solitary, the young gregarious. They are active predatory fish that feed on fish, mollusks, and cephalopods (octopus, cuttlefish, and squid). In the summer they approach the shore, but in winter migrate to deeper water.

The dentex have oval shaped rather deep bodies with a massive, smoothly rounded head in adults. Very large individuals have a profile with a slight frontal hump. Both jaws have well-developed canine like teeth plus several rows of smaller teeth of similar shape. The dorsal fin has 11 spines and 11 or 12 soft rays, the spines increasing in length from the first to the fourth or fifth then subequal. The lateral line has 62 68 scales. Color is variable but young are dentex are grayish, spotted with black on the back and upper sides, becoming pinkish with sexual maturity. Older individuals are bluish gray with spots becoming more or less diffuse with age. Some have a yellow tinge behind the mouth and on the gill cover.

They can be distinguished from other similar species by the dark spots, which are always present and the several rows of canine like teeth. Other species have more than one type of teeth or incisor like teeth.

Fishing methods include trolling with dead bait, live bait like mackerel, garfish, boga and squid or artificials such as rapalas in 10 to 50 m (33 to 165 ft). Bottom fishing in deeper waters with both live and dead bait such as anchovies, sardines, octopus or squid is also productive. They are very clever fish, needing small hooks and light leaders. A very popular game fish and esteemed table fish, they reportedly reach a weight of around 15 kg (33 lb)

Pollock Pollachius virens

Pollock Pollachius virens
Linnaeus, 1758

GADIDAE FAMILY
Also called coalfish, Boston bluefish, green cod, blisterback, saithe, coley

Found on both sides of the Atlantic, from Greenland and Labrador to Virginia on the west side, and on the east, from Iceland to northern Spain, including the Bay of Biscay, the English Channel, and western Baltic and North Sea.

It is said to be the most active member of the cod family Gadidae. Though it occurs in shallower waters than either the cod or haddock, it is generally a deep or midwater fish occurring in depths of up to 100 fathoms. It will sometimes chase bait fish to the surface and smaller individuals are often seen milling about at the surface in large, tightly packed schools. In the western Atlantic south of Cape Cod, Massachusetts, off the U.S. east coast, pollock can be taken from depths of 25 fathoms to as little as 4 fathoms. North of Cape Cod where most of the fish are taken, they have even been caught by surf fishermen.

They can be distinguished from other members of the cod family by three features. Its lower jaw projects beyond the upper jaw, its tail is forked, and its lateral line is quite straight, not arching above the pectoral fins. Young pollock have cod like barbels on the chin, but these are small and usually disappear with age. The back varies from olive green to greenish brown. The flanks are a lighter yellowish green or gray.

Its diet consists of smaller pelagic fishes, sand eels and various crustaceans. Fishing methods include bait fishing or jigging with shrimp, herring, squid, clams, worms, or jigs, trolling or casting with spoons, tube lures, spinners, plugs, or flies. It makes strong, powerful runs and occasionally leaps and shakes. The flesh is of good quality and is commercially important.

Taimen Hucho taimen

Taimen Hucho taimen
Pallas, 1773

SALMONIDAE FAMILY
Also called taimen salmon

There are four species of the genus Hucho, which include the species Hucho hucho, the huchen and Hucho hucho taimen, the taimen. While the two subspecies of Hucho hucho cannot be separated on the basis of morphology or meristics, their geographical separation allows us to distinguish between the two.

The huchen is restricted to the Danube River drainage and the taimen to the Ural Siberian Amur drainages, most of which flow into the Arctic Ocean. Ranges of the huchen and taimen are disjunct (do not overlap) and are separated by the Eastern European Flatland.

The taimen inhabits large rivers with fast currents, often to their estuaries. It also occurs in lakes. In spring, it ascends the rivers and enters shallow creeks, spawning in May.

They probably attain the largest sizes of any salmonid fish. A report exists of a 231 lb specimen taken in a commercial net in 1943, but the largest authenticated record is 123 lb (55.8 kg), slightly less than a commercially caught 126 lb (57.2 kg) Chinook salmon.

Physically, they resemble a northern pike. The body is round and elongated and the head flattened with an enormous terminal mouth. Like huchen, taimen are specked with dark spots over the entire body, predominating on the upper portions, including the head and fins. The tail and anal fins are a crimson red. During the spawning period, almost all the body becomes copper red.

Taimen fishing is similar to that of huchen, flies, plugs, large spoons, and spinners are all highly effective, and of coarse, any live bait should be productive. The voracious taimen reportedly will strike at anything resembling wounded prey. Just as large prey are sought by large fish, lure size should match the size of fish sought by the angler, monster fish require monster baits!

While huchen populations have diminished rapidly with over exploitation and habitat deterioration, taimen are just emerging as a popular sportfish. Hopefully, with due care from concerned anglers, the taimen population will not suffer the same fate

Sailfish, Pacific Istiophorus platypterus

Sailfish, Pacific Istiophorus platypterus
Shaw, Nodder 1791

ISTIOPHORIDAE FAMILY
Also called spindlebeack, bayonetfish

Inhabits tropical and subtropical waters near land masses, usually in depths over 6 fathoms, but occasionally caught in lesser depths and from ocean piers. Pelagic and migratory, sailfish usually travel alone or in small groups. They appear to feed mostly in midwater along the edges of reefs or current eddies.

Its outstanding feature is the long, high first dorsal which is slate or cobalt blue with a scattering of black spots. The second dorsal fin is very small. The bill is longer than that of the spearfish, usually a little more than twice the length of the elongated lower jaw. The vent is just forward of the first anal fin. The sides often have pale, bluish gray vertical bars or rows of spots.

Its fighting ability and spectacular aerial acrobatics endear the sailfish to the saltwater angler, but it tires quickly and is considered a light tackle species. Fishing methods include trolling with strip baits, plures, feathers or spoons, as well as live bait fishing and kite fishing. The most action is found where sailfish are located on or near the surface where they feed.

Recent acoustical tagging and tracking experiments suggest that this species is quite hardy and that survival of released specimens is good

Catfish, redtail (pirarara) Phractocephalus hemioliopterus

Catfish, redtail (pirarara) Phractocephalus hemioliopterus
Bloch, Schneider, 1801

PIMELODIDAE FAMILY
Also called bigoril, pirarara, guacamayo, pez torre, peixe-arara

The pirarara or redtail catfish is one of the most colorful of the large catfishes found in the Amazon and Orinoco basins. In its natural habitat, the redtail catfish is found in larger rivers, streams and lakes. During high water, it ventures into the flooded forests.

The pirarara is a very distinctive species. The brownish back, yellow sides and red-orange dorsal and caudal fins make this catfish very recognizable. Three pairs of barbels are present, one pair on the upper and two pairs on the lower jaw.

The redtail catfish is omnivorous in its feeding habits with a diet that can include fish, crabs and fruits. This species, which grows in excess of 4 ft (121 cm) and 100 lb (45 kg) is considered to be the one of the best fighting of the catfishes with strong and determined runs. Pirarara are most often caught with natural baits and pose a challenge to anglers using artificial lures or flies.

It is used as a food fish throughout its range and is said to be excellent, if somewhat dark meat

Grouper, goliath Epinephelus itajara

Grouper, goliath Epinephelus itajara
Lichtenstein, 1822

SERRANIDAE FAMILY
Also called spotted jewfish, southern jewfish, junefish, Florida jewfish, jewfish

Known to occur in the western Atlantic Ocean from Florida to Brazil, including the Gulf of Mexico and the West Indies. It is also known in the eastern Pacific from Costa Rica to Peru. This species is usually found inside of the 12 fathom bottom contour, though it may occur in deeper waters. It favors areas near rocky shores and islands, reefs, ledges, dock and bridge pilings, and wrecks, where caves and holes offer refuge.

The goliath grouper is the largest of the grouper in the western Atlantic, possibly reaching 8 ft (2.5 m) and a weight of 1000 lb (455 kg). The body, including the head and fins, is mottled with dark brown blotches and blackish spots. As the fish grows older, the body becomes darker and the spots and blotches become more numerous and less distinct

It can be easily distinguished from the giant sea bass, Stereolepis gigas, because it has more soft rays (15 16) than spines (11) in the dorsal fin. The giant sea bass also has 11 spines, but only 10 soft rays. The goliath grouper can also be distinguished from the giant sea bass by its rounded tail fin, large, rounded pectoral fins, and different color pattern.

Goliath grouper feed primarily on crustaceans, but also on fishes and even an occasional turtle, which is inhaled into the goliath grouper’s enormous mouth. It is a very sluggish fish and an opportunistic feeder. Some very large specimens show an extraordinary degree of curiosity and will leave their caves to swim up to a diver. There are reliable reports of goliath grouper or giant sea bass interfering with diving operations and occasionally even attempting to swallow divers.

Despite poor fighting ability, its great size and weight and its habit of swimming into a hole or between rocks when hooked, make it difficult to land. They can be taken on live or dead bait fished on the bottom from boats, bridges, or shore. Slow trolling also works on occasion. Baits include crabs, spiny lobster, fishes and cut bait.

The goliath grouper is an excellent food fish at any size. But, it is now totally protected from harvest in Florida waters
