General Body Form:

    Black Crappies are a monomorphic species characterized by 7-8 dorsal spines which are stepped in length, an upturned (S-Shaped) snout, symmetrical dorsal and anal fins, a wavy light and dark pattern on non-paired fins and a mottled(spotty) color pattern.


Coloration:

    There are color variances among the populations of black crappie,. Age, habitat, and breeding are all determinants of the intensity and patterns of mottling: juveniles tend to have less pigment and pattern the adults; those black crappies living in clear vegetated water have strikingly bolder patterns than those living in turbid, murky water, breeding males have a darker head and breast the normal populations.


Maintenance:

    Favors clear, warm, highly vegetated water, sandy substrate with driftwood for hiding.

    Diet:
    As a juvie, eats macroscopic prey such as Cyclops, Cladocera, and Daphina, as an Adult, mid water omnivore that feeds in vegetation and open water. Its numerous gill rakes allow it to consume planktonic crustaceans, however aquatic insects, minnows, and fingerlings of other species comprise its main diet. Dawn, noon, dusk and midnight are peak times for black crappie feeding, eats all types of food forms year around.


Biotope:
    Inhabits lakes, ponds, sloughs, and backwaters and pools of streams. Usually occurs among vegetation over mud or sand, most common in clear water.

    Both sexes of black Crappie reach their sexual maturity by the age of two, spawning is between the months of April and June in nature. The Female is very fertile and bears 10,000-20,000 eggs (varies with size and age of female) once the eggs are in the nest it is the males responsibility to guard the nest, until the young can freely swim and feed
