North Carolina State Fish

North Carolina State Fish

Red Drum/Channel Bass (common name)
Sciaenops ocellatus (scientific name)

Overview

The red drum is a medium-sized saltwater fish that gets its name from both its typical reddish-copper color (even though it also ranges from silver to black) and the drumming sound males produce when they spawn to attract females. The fish produce the noise by contracting a muscle in their air bladders. The red drum has one large black spot on the upper part of the tail base, in addition to other scattered spots. A cousin to the black drum, the two species often interbreed to create a hybrid. The drum is a popular target for recreational fishermen due to its size, proximity to shore, and its fine flavor when cooked. North Carolina designated the red drum the official state saltwater fish in 1971, and the largest red drum caught on record was captured in North Carolina.

STATUS
Official State Saltwater Fish
PHYSICAL DETAILS
Length: Up to 27 in (69 cm); average of 24 in (60 cm)
Weight: Up to 94 lbs (43 kg); average of 7 lbs (3 kg)
LIFESPAN
Up to 37 years
HABITAT
Temperate oceans. Younger fish live in near-shore bays and channels at depths of 1–4 feet (30–120 cm) where there are muddy bottoms and abundant sea grasses.
Range: The Atlantic coast from Massachusetts to Florida, and the coast of the Gulf of Mexico from Key West to Tuxpan, Mexico.
Water type: Saltwater, brackish water, freshwater
Water temp: Approximately 75°F (23°C)
Conservation Status: Vulnerable; successful conservation efforts have led to increased populations of the species in recent years.
DIET
Crustaceans (crabs, shrimp), fish (croakers), worms, and mollusks.
REPRODUCTION
Fertilization: External
Spawning frequency: Mid-August to mid-October
Mating behavior: Group
Egg laying: The channel bass spawns in shallow river estuaries and lagoons. As the fry grow, they move into deeper water near the mouths of bays and inlets and then, at four years of age, go out to sea. Females broadcast eggs randomly in the spawning grounds and the males fertilize them. A female can lay up to two million eggs a season.
USES
Game fish, limited commercial fishing
OTHER NAMES
Channel bass, redfish, spot-tail bass, red bass, red dorse, school drum, puppy drum, red, rat red, bull red
TRIVIA
  • The black spot near the red drum’s tail is believed to help the fish fool predators into attacking its tail rather than its head.
  • Red drum will swim and forage in such shallow water that their backs and tailfins are sometimes exposed.

North Carolina State Fish

Southern Appalachian Brook Trout (common name)
Salvelinus fontinalis (scientific name)

Overview

This speckled trout belongs to the same family as salmon, and is technically a char, not a trout. The fish’s streamlined body is green to brown with lighter dots and marbling, sometimes with some bluish shading on the dots. This pattern often runs the full length of the fish’s body. Its belly has a red blush, and its lower fins are a similar color, edged with white. During spawning season, the fish’s red patches intensify, especially in males. The trout’s sides are always a little lighter-colored than its back.
The Southern Appalachian brook trout lives only in fresh water. It is relatively small and a short-lived fish, surviving an average of five years. Fly fishermen in particular are fond of this species as a game fish, though many fishermen prefer to catch and release this fish. It is native to the eastern U.S. and needs cold, clean water to survive, but has been introduced almost worldwide both for sport and food. Southern Appalachian Brook Trout is the only freshwater fish that’s native to North Carolina. It became the state’s official freshwater fish in 2005.

STATUS
Official State Freshwater Trout
PHYSICAL DETAILS
Length: 10–25 in (25–65 cm); record length 33 inches (86cm)Weight: 0.3 to 3 kg (10.5 oz to 7 lbs), record weight 6.6 kg (15 lbs)
LIFESPAN
3-7 years
HABITAT
Range: Native to eastern North America from Newfoundland to Hudson Bay, the Great Lakes and Minnesota south along the Mississippi River basin to Georgia and east to the Atlantic Ocean. Introduced to the western U.S., 20 European countries, and parts of Asia, Africa, Oceania, and South America.
Water type: Freshwater
Water pH range: 5 to 7.5
Elevation: 1,600 ft
Conservation Status: In its native range, the brook trout is often threatened by pollution and overfishing. In areas where it has been introduced, on the other hand, it can sometimes be invasive and compete with and displace native species.
DIET
Crustaceans, frogs, mollusks, insects, smaller fish, worms, and occasionally aquatic mammals such as voles.
REPRODUCTION
Fertilization: External
Spawning frequency: Annual
Mating behavior: Distinct pairing
Egg laying: Unguarded, in gravel
USES
Game fish, aquaculture
OTHER NAMES
Speckled trout, brookie, squaretail, char, sivon, specks, whitefin
TRIVIA
  • Presence of brook trout means good water quality and a healthy, working watershed.
  • Brook trout occasionally eat their own eggs at spawning time.
  • This trout is a carnivorous, opportunistic feeder and will snap up anything that looks at all like food.
