The
largemouth bass (
Micropterus
salmoides) is a
species of
fish in the
sunfish family. It is also known as
widemouth bass,
bigmouth,
black bass,
bucketmouth,
Florida bass,
Florida largemouth,
green bass,
green trout,
linesides,
Oswego bass,
southern largemouth
and (paradoxically)
northern largemouth.
The
largemouth bass is the state fish of Alabama
(official
freshwater fish), Georgia
, Mississippi
, Florida
(state
freshwater fish), and Tennessee
(official sport fish).
Physical description
The largemouth is a olive green fish, marked by a series of dark,
sometimes black, blotches forming a jagged horizontal stripe along
each flank. The upper jaw (
maxilla) of a
largemouth bass extends beyond the rear margin of the
orbit. The largemouth is the largest of the
black basses, reaching a maximum recorded overall length of and a
maximum recorded weight of . The fish lives 16 years on
average.
Forage
The juvenile largemouth bass consumes mostly small bait-fish,
scuds,small shrimp, and
insects. Adults
consume smaller fish (bluegills), crawfish (
crayfish),
frogs,
snakes,
salamanders,
bats and even small
water
birds,
mammals, and baby
alligators. In larger lakes and reservoirs, adult
bass occupy deeper water than younger fish, and shift to a diet
consisting almost entirely of smaller fish like
shad,
trout,
ciscoes,
shiners,
and
sunfish. Prey items can be as
large as 25 to 35% of the bass's body length. Studies of prey
utilization by largemouths show that in weedy waters, bass grow
more slowly due to difficulty in acquiring prey. Less weed cover
allows bass to more easily find and catch prey, but this consists
of more open-water baitfish. Paradoxically, with little or no
cover, bass can devastate the prey population and starve or get
stunted. Fisheries managers need to take all these factors into
consideration when designing regulations for specific bodies of
water. Under overhead cover such as overhanging banks, brush, or
submerged structure such as weedbeds, points, humps, ridges, and
drop-offs, the largemouth bass will use its senses of hearing,
sight, vibration, and smell to attack and seize its prey. It can
sometimes hold up to 5 sunfish in its mouth. Adult largemouth
generally are
apex predators within
their habitat, but they are preyed upon by many animals while
young.
Angling
Largemouth are keenly sought after by
angler
and are noted for the excitement of their fight. The fish will
often become airborne in their effort to throw the hook, but many
say that their cousin species, the
smallmouth bass, can beat them pound for
pound. Anglers most often fish for largemouth bass with
lure such as
plastic
worms (and other plastic baits),
jigs,
crankbaits and
spinnerbaits.
A recent trend is the
use of large swimbaits to target trophy
bass that often forage on juvenile rainbow
trout in California
. Live bait, such as
nightcrawlers,
minnows,
frogs, or
crawfish can also be productive. In fact, large
golden shiners are one of the best
things to use to catch trophy bass, especially when they are
sluggish in the heat of summer time or in the cold of winter.
Largemouth bass are known to take any bait it considers
alive.
There is a strong cultural pressure among largemouth bass anglers
which encourages the fish's live release, especially the larger
specimens. Largemouth bass, if handled with care, respond well to
catch and release; many studies
have shown specimens which have survived being hooked and released
multiple times.
The Largemouth Bass has been known to exist in many of the lower 48
states of the U.S. Although it is most popular in the southeastern
states, many different varieties of the largemouth bass can be
found in the north and western regions.
The
International Game Fish
Association
(IGFA) officially recognizes the heaviest
largemouth bass on record as having been caught by George Perry at
Montgomery Lake in Telfair
County
, Georgia
, on June 2, 1932. The fish weighed
10 kg (22ΒΌ lb).
A largemouth bass weighing 25 pounds 1 ounce
was caught by Mac Weakley in Escondido
, California
's Dixon Lake on March 20, 2006, but Weakley
inadvertently foul-hooked the fish and released it without
submitting it for a IGFA record.
