Redear sunfish
The redear sunfish, also known as
the shellcracker, is often stocked as
forage in conjunction with the
bluegill in the Southeast and in other
waters that remain turbid. Bass may
not be able to readily see their prey
in these waters and as a result,
bluegill may not be satisfactorily utilized.
The redear is less prolific than the bluegill and since their young
compete for food, may help reduce
total sunfish reproduction.
Redear sunfish
The principles of redear production
are similar to those utilized in the
culture of bluegills. However, redears
do not adapt to formulated
feeds as readily as bluegills because
of their more predatory nature.
Artificial diets can be fed at 0.5 to
2 percent of body weight depending
on temperatures. Ponds rich in zooplankton
and aquatic insect life
should assist in increasing production.
Hybrid sunfish crosses utilizing the
redear sunfish as one parent should
not be cultured or stocked as a
forage fish. The reproductive potential
of these hybrids is greatly reduced
and the resulting offspring are
insufficient for sustaining a bass
population.


Once water temperatures reach
appropriate levels, spawning will
begin. Warmouth and green sunfish
are the first to spawn, with
activity beginning at 70 oF (21 oC).
Redear spawn when water temperature
reaches 75 oF (24 oC),
whereas bluegills do not spawn
until temperature reaches 78 to
80 oF (26 to 27 oC). All species
begin nest building and territorial
behavior at temperatures several
degrees cooler than the optimum
spawning temperature.
