Overview

The Redfish, also known as Red Drum, is a large member of the drum family Sciaenidae, native to the coastal waters of the Gulf of Mexico and the western Atlantic from the northeastern United States to northern Mexico. It is one of the most recognizable estuarine sport fish in North America, prized for its coppery coloration and characteristic black tail spot. Redfish were subject to intense commercial fishing pressure in the 1980s that led to significant population declines, prompting strict management measures across much of its range; populations have since recovered substantially under regulated harvest limits.

How to identify it

Redfish have a robust, elongated body with a coppery bronze to reddish-orange back fading to a silvery-white belly, a coloration that intensifies in shallow, sunlit flats.

  • One or more distinct black eyespots, usually ringed in pale color, near the base of the tail (occasionally multiple spots)
  • Slightly humped back and a blunt, downturned snout adapted for feeding along the bottom
  • No barbels on the chin, unlike some other drum species
  • Large, tough scales and a stout, muscular body
  • Typically 40-100 cm in coastal waters, with older 'bull reds' growing much larger offshore

Habitat & range

Redfish inhabit shallow coastal waters, estuaries, seagrass flats, and marsh edges along the Gulf of Mexico and southeastern Atlantic coast of the United States and northern Mexico. Juveniles and sub-adults favor brackish estuaries, tidal creeks, and grass flats with abundant cover, while larger adults, known as 'bull reds,' move into higher-salinity nearshore and offshore waters to spawn and feed. Redfish tolerate a wide range of salinities and temperatures, often found in warm, shallow, structure-rich habitats over sand, mud, or grass bottoms.

Behavior & ecology

Redfish are opportunistic bottom-oriented predators, often seen 'tailing' in shallow water with their tails breaking the surface as they root along the bottom for crabs, shrimp, and small fish. They frequently form schools, especially as juveniles and during seasonal movements, and are highly active in warm, shallow flats during calm conditions. Adults migrate to nearshore and offshore waters to spawn in late summer and fall, releasing large numbers of eggs that drift with currents before hatching; larvae are carried into estuarine nursery habitats where juveniles spend their early years. Their strong site fidelity to estuarine habitat makes them sensitive to changes in water quality and habitat loss.

Frequently asked questions

What is the black spot near a Redfish's tail for?

The eyespot is thought to confuse predators into striking the tail instead of the head, helping the fish escape.

What is a 'bull red'?

It's the common name for larger, older Redfish that have moved from estuarine flats into higher-salinity nearshore and offshore waters.

What do Redfish eat?

They are opportunistic bottom feeders, primarily consuming crabs, shrimp, and small fish along shallow flats and estuary bottoms.
