Description
Rainbow trout possess the well-known
streamlined shape, although body shape
and coloration can vary widely and
reflect habitat, age, sex, and degree
of maturity. The body shape may range
from slender to thick. The back may
shade from blue-green to olive. There
is a reddish-pink band along each
side about the midline that may range
from faint to radiant. The lower sides
are usually silver, fading to pure
white beneath. Small black spots are
present over the back above the lateral
line, as well as on the upper fins
and tail. River or stream residents
normally display the most intense
pink stripe coloration and heaviest
spotting followed by rainbows from
lake and lake-stream systems. Spawning
trout are characterized by generally
darker coloration
Habitat
They are stocked in many lakes and
streams. Rainbows are happy in either
fast flowing water of upper reach's
of major river systems, but also equally
happy in landlocked waters either
of a natural nature or man made. In
streams these fish can often be found
enjoying the clean gravel, gliding
gracefully in between streamer weed.
Feeding Habit
They feed primarily on aquatic and
terrestrial insects and small first.
Rainbows like most Trout are top and
bottom feeders. Often seen at first
light or as dusk sets taking the new
hatch as it rises.
Age and Growth
Sexual maturity varies markedly between
individuals due primarily to such
factors as population density, productivity
of the aquatic environment, and genetic
makeup. In the wild, male and female
spawners as young as ages 3 and 5,
respectively, have been found, but
a majority of both sexes mature at
age 6 to 7. Spawning frequency ranges
from annually to once each three years.
Rainbow up to age 11 have been observed
spawning.
Tackle and Methods
Fly fishermen spend a lot of time
taking fishing trips around the world
in pursuit of rainbow trout. But you
can also use spinners, wobbling spoons,
streamer flies, are all especially
effective. Usually people use large
lures and baits to catch the bigger
fish.
