Pumpkinseed,
September 2014, Fish of the Month!
A brief note about
this family of Fishes: The Sunfish family includes a large number of
very North American species. We're including many of them here (in
spite of their often small size) because they make excellent
warm-water training species for young anglers and because adult
warm-water fly-fishers are likely to often take them as incidental
catches and would like to know what species they've brought to hand.
Pumpkinseed
Lepomis gibbosus
Local Names:
Sunny, Common
sunfish, Kivvy, Kibbie, Yellowbelly, Quiver, Roach, Sunfish, Sun
bass, Punky
Average Size:
7 to 8 inches
Distinguishing Field
Marks:
(See the
illustration.)
Deep almost
round body, with a high rounded back.
The head is not
large in comparison to the body.
The eye is large
and dark colored.
There are pale
aqua-blue irregular streaks on the gill covers and cheeks.
The opercular
(ear) flaps are relatively short with black interiors bordered by a
white outside edge with a short red mark just below the center of the
flap. This red mark on the "ear-flap" is a reliable field
mark to distinguish this species from the Bluegill.
The mouth is
small and tipped upward. The upper jaw extends back only to the front
edge of the eye.
The first dorsal
fin has 10 spines and is fully attached to the second dorsal.
The tail is
slightly forked with rounded lobes.
The anal fin has
3 graduated spines.
The paired
pelvic fins have 1 spine and pointed tips.
The pectoral
fins are large, nearly transparent, and pointed.
Diet:
Throughout their
lives, Pumpkinseeds feed almost exclusively on immature and adult
aquatic insects and other invertebrates. They often feed at or near
the water's surface.
Biology:
Genus-typical winter
aggregations of Pumpkinseed sunfish break up at water temperatures of
about 50 degrees F. when mature males move to shallower areas, choose
and defend nesting territories, and begin fin-fanning the bottom to
open nests that are situated very close together.
Water temperatures
in these shallow nesting areas rise quickly inducing spawning that
may last from June well into August. With the completion of the
nests, females will begin entering the colony and males will rush to
them and commence a courtship dance which involves their swimming in
circles around and over the female with which they choose to spawn.
When the pairs are ready, they begin circling the nest and then the
female tips her body, with the male remaining upright, and their
vents touching. Small batches of eggs and milt are released and
settle into the bottom of the nest. The pair then goes back to
circling the nest in preparation for another spawning. This ritual
may go on over the course of a day or two. Females may mate with
several males and breeding pairs may also spawn over nests which are
not their own. The eggs, guarded and aerated by the male parent,
incubate for a period of from 3 to 5 days, and the male remains at
the nest site, protecting the newly-hatched fry for a short period.
As adults,
Pumpkinseeds are found in shallow rocky or weedy areas of lakes,
ponds, and slower portions of some streams.
Fly Fishing for
Pumpkinseed:
Now widely
distributed in the United States and southern Canada, the Pumpkinseed
is one of the most frequently caught members of its genus. This
colorful, aggressive, hard-fighting species is very willing to take a
broad range of small offerings. Wet and dry flies, and small poppers,
will all entice Pumpkinseed to strike.
Fly fishing gear in
the 3 to 5 weight range is best for handling these fish. As
Pumpkinseeds frequently take food at the surface, occasionally gain
good size, and are very strong battlers, using their deep slab-sided
bodies to their best advantage when hooked, using small foam bodied
poppers on a floating line is a very enjoyable sight-fishing approach
to taking these rather elegant fish.
Significance to
Humans:
One of the most
common of our small sunfishes, the Pumpkinseed is an excellent sport
fish for its size and is also a fine fish for the table. It is also
another of our small sunfishes that can thrive in the habitat of a
home aquarium.
Status:
Thriving throughout
its broad North American range.
