Freshwater Fish Identification
Black Bullhead
Ameiurus melas
Other names: Polliwog, chucklehead cat
Status: Texas nongame
fish
Description
Ameiurus is Greek and means "primitive" or "curtailed" in reference
to the slight notch in the caudal fin; melas is also Greek and means
"black." Black bullheads are typically black to greenish-black on the back,
ranging to gray or white on the belly. However, in muddy water the back may be
yellowish-brown. Chin barbels are dark or black, never white. The anal fin has
17-21 rays.
Angling Importance
Black bullheads are not generally considered an important gamefish in Texas,
though they are readily fished for by anglers in the Panhandle, and in far East
Texas. A variety of baits may be used to catch them, but worms are usually the
best. The largest specimen reported to date in Texas was 4.53 pounds.
Biology
During late spring or early summer black bullheads excavate nests in mud
bottoms and spawn. Areas with some sort of cover are preferred. Nests contain
golden-yellow egg masses which are guarded by both parents (at least one is
present at all times). Eggs hatch in four to six days. Fry begin to school in
compact balls which are guarded by adults until individuals reach about one inch
in length. Black bullheads are omnivorous, feeding primarily from the bottom on
a wide range of plant and animal material, both live and dead. Fingerlings feed
almost exclusively on crustaceans. Immature aquatic insects and crustaceans
often comprise a considerable proportion of the adult diet. The average life
span is usually less than five years, and most adults are less than one pound.
However, some individuals may live more than 10 years and reach eight
pounds.
Distribution
The original distribution of the black bullhead included the central plains
west of the Appalachians and east of the Rockies, extending north into
Saskatchewan and Manitoba, and south into south Texas and New Mexico. Today
artificial introductions have extended the range west of the Rockies in isolated
pockets including areas of British Columbia, Alberta, Mexico, California,
Arizona, Nevada, and Idaho. In Texas the black bullhead is distributed statewide
with the exception of the Trans-Pecos drainage.
