Found
from extreme southwestern Quebec in the St. Lawrence,
Richelieu and Ottawa river basins, southern Ontario
including all the Great Lakes, and southern Manitoba.
Also introduced to the lower Fraser River in British
Columbia. In the U.S. south to Florida and Texas
and west to Montana but widely introduced. Behaviour
& Habitat: This schooling crappie is found in
still waters of lakes and ponds or slow flowing,
large rivers where there is abundant plant material
or other cover. It prefers cooler and deeper water
than the white crappie and is less tolerant of
turbid conditions, growing more slowly there than
in clear waters. It may enter brackish waters
in the St. Lawrence River. Food includes plankton,
aquatic insects and fish fry when young. In the
Ottawa River copepods and water fleas are the
main diet of young-of-the-year, switching to amphipods
in the fall. Even adults may rely principally
on water fleas for food, taken by filter feeding
in mid-water using the numerous gill rakers, but
fish become increasingly important as black crappies
grow. Feeding continues through winter, an unusual
habit in a sunfish. The black crappie is a predator
on the young of sport fishes and may affect population
numbers significantly. Peak feeding is between
early evening and the early morning hours around
dawn. Life span is 13 years with maturity at one
to three years. Growth varies with habitat and
latitude to some degree. Spawning occurs from
May to June in Ontario. This species enters into
commercial catches.
