Drum Black (lat. Pogonias cromis)
The black drum is the largest member of the Sciaenidae
family (drum and croaker). The common term “drum”
refers to the loud and distinctive “drumming” noise that
occurs when the fish raps a muscle against the swim bladder.
This voluntary noise is assumed to be associated with
locating and attracting mates, and it can sometimes be
heard from a good distance, even by people above the
water.

The black drum has a short, deep, and
stocky body, with a high, arched back and a slightly concave
tail. The lower jaw sports numerous barbels, or short
whiskers. There are large pavementlike teeth in the throat,
and the mouth is low. The dorsal fins have 11 spines, 20 to
22 dorsal rays, and 41 to 45 scales along the lateral line,
which runs all the way to the end of the tail. Coloring is silvery
with a brassy sheen and blackish fins, turning to dark
gray after death.
Average small drum weigh 5 to 10 pounds;
large specimens commonly weigh 20 to 40 pounds. In
Delaware Bay, fish from 40 to 70 pounds are fairly common
in the spring. The all-tackle record is 113 pounds. Black
drum live up to 35 years.
Black drum adults form schools
and migrate in the spring to bay and river mouths for the
spawning season; in the Gulf of Mexico this is from February
to May. Larval black drum remain in shallow muddy
waters until they are 4 to 5 inches long; then they move
near shore.
Adult black drum feed on crustaceans
and mollusks, with a preference for blue crabs,
shedder crabs, shrimp, oysters, and squid. They locate food
with their chin barbels and crush and grind shells with their
pharyngeal teeth.
Black drum
are found in the western
Atlantic Ocean, from
Massachusetts to southern
Florida and across the Gulf
of Mexico to northern Mexico.
They rarely occur north
of New Jersey.
An inshore bottom
fish, the black drum
prefers sandy bottoms in
salt or brackish waters near
jetties, breakwaters, bridge
and pier pilings, clam and
oyster beds, channels, estuaries,
bays, high marsh
areas, and shorelines.
Larger fish often favor shoal
areas and channels.
Black drum can survive
wide ranges of salinity and
temperature. The small fish
inhabit brackish and freshwater
habitats; the adults
usually prefer estuaries in
which salinity ranges from 9
to 26 parts per thousand
and the temperature ranges
from 53° to 91°F.
