Walleye Fishing Information
Author: George
The Walleye is a freshwater perciform fish
native to most of Canada and to the
northern United States. The walleye is
sometimes also called the yellow walleye to
distinguish it from the blue walleye.
In some parts of its range, the fish is known
as the yellow pike or pickerel, although the
use of these names should be discouraged
since the fish is related neither to the pikes
nor to the pickerels, both of which are
members of the family Esocidae.
Genetically, walleyes show a fair amount of
variation across watersheds. In general,
fish within a watershed are quite similar
and are genetically distinct from those of
nearby watersheds.
The species has been artificially
propagated for over a century and has
been planted on top of existing
populations or introduced into waters
naturally devoid of the species, sometimes
reducing the overall genetic distinctiveness
of populations.
The common name, "walleye", comes from
the fact that their eyes, not unlike those of
cats, reflect light. This is the result of a
light-gathering layer in the eyes called the
tapetum lucidum which allows them to see
well in low-light conditions.
In fact, many anglers look for walleyes at
night since this is when most major feeding
patterns occur. Their eyes also allow them
to see well in turbid waters (stained or
rough, breaking waters) which gives them
an advantage over their prey. Thus, walleye
anglers will commonly look for days and
locations where there is a good "walleye
chop" (i.e. rough water).
Walleyes are largely olive and gold in. The
dorsal side of a walleye is olive, grading
into a golden hue on the flanks. The
olive/gold pattern is broken up by five
darker saddles that extend to the upper
sides.
The color shades to white on the belly. The
mouth of a walleye is large and is armed
with many sharp teeth. The first dorsal and
anal fins are spinous as is the operculum.
Walleyes are distinguished from their close
cousin the sauger by the white coloration
on the lower lobe of the tail.
The walleye is a relatively r-selected
species. They require fairly clean waters
and are found most often in deep
mesotrophic lakes and moderate- to low-
gradient rivers. The walleye is considered a
"cool water" species. Adults migrate to
tributary streams in late winter or early
spring to lay eggs over gravel and rock,
although there are open water reef or
shoal spawning strains as well.
Some populations are known to spawn on
sand or on vegetation. A large female can
lay up to 500,000 eggs and no care is given
by the parents to the eggs or fry. The eggs
are slightly adhesive and fall into spaces
between rocks.
The incubation period for the embryos is
temperature-dependent but generally lasts
from 12 to 30 days. After absorbing the
small amount of yolk, young walleyes begin
feeding on invertebrates. After 40 to 60
days, juvenile walleyes become
piscivorous. After this time, both juvenile
and adult walleyes eat fish almost
exclusively, frequently yellow perch or
ciscoes, moving onto bars and shoals at
night to feed.
The walleye is often considered to have the
best tasting flesh of any freshwater fish,
and, consequently, is fished recreationally
and commercially. Because of its nocturnal
feeding habits, it is most easily caught at
night using live minnows or lures that
mimic small fishes.
Most commercial fisheries for walleye
occur in the Canadian waters of the Great
Lakes but there are other locations as well.
One of the best lakes for catching walleyes
is Mille Lacs in central Minnesota.
