Description
- The
striper is the largest member of the temperate bass family. Body
coloration is
olive-green to blue-gray on the back with silvery to brassy sides and
white on
the belly. It is easily recognized by the seven or eight prominent
black
uninterrupted horizontal stripes along the sides. The stripes are often
interrupted or broken and are usually absent on young fish of less than
six
inches. The striper is longer and sleeker and has a larger head than
its close
and similar looking relative, the white bass, which rarely exceeds
three
pounds.
Habitat
- All
Florida populations of striped bass are river dwellers rather than
anadromous
(normally living in salt or brackish waters, but entering freshwater
streams to
spawn). The species has been widely introduced in numerous lakes,
rivers and
impoundments throughout the world. Stripers prefer relatively clear
water with
a good supply of open-water baitfish. Their preferred water temperature
range
is 65 to 70 degrees.
Spawning
Habits -
Spawns in
March, April and May when water temperatures reach 60 to 68
degrees.
Stripers are river spawners that broadcast millions of eggs in the
water
currents without affording any protection or parental care. During
spawning,
seven or eight smaller males surround a single, large, female and bump
her to
swifter currents at the water surface. At ovulation, ripe eggs are
discharged
and scattered in the water as males release sperm. Fertilized eggs must
be
carried by river currents until hatching (about 48 hours) to avoid
suffocation.
Fry and fingerlings spend most of their time in lower rivers and
estuaries.
Because striped bass eggs must remain suspended in a current until
hatching,
impoundments are unsuitable for natural reproduction. Freshwater
populations
have been maintained by stocking fingerlings, and, despite initial
difficulties
in hatchery procedures for obtaining females with freely flowing eggs,
a modern
technique of inducing ovulation with the use of a hormone has been
successful.
Feeding
Habits -
Stripers are
voracious feeders and consume any kind of small fish and a
variety
of invertebrates. Preferred foods for adults mainly consist of gizzard
and
threadfin shad, golden shiners and minnows. Younger fish prefer to feed
on
amphipods and mayflies. Very small stripers feed on zooplankton. Like
other
temperate bass, they move in schools, and all members of the school
tend to
feed at the same time. Heaviest feeding is in early morning and in
evening, but
they feed sporadically throughout the day, especially when skies are
overcast.
Feeding slows when water temperatures drop below 50 degrees but does
not stop
completely.
Age and Growth -
Stripers are
fast-growing and
long-lived and have reached weights of over 40 pounds in Florida.
Sexual
maturity occurs at about two years of age for male stripers and at four
years
of age for females. They can reach a size of 10 to 12 inches the first
year. |
