Hybrid crappie (Pomoxis annularis × nigromaculatus) have been cultured and occur naturally. [22] The crossing of a black crappie female and white crappie male has better survival and growth rates among offspring than the reciprocal cross does. [22] Hybrid crappie are difficult to distinguish from black crappie by appearance alone.

It is very similar to the white crappie (P. annularis) in size, shape, and habits, except that it is darker, with a pattern of black spots.

White crappies are also slightly more elongated than black crappies. [8] The white crappie is a deep-bodied fish with a flattened body, or a depth that is one-third of the length of the fish. White crappies have spinous rays and ctenoid fish scales found in advanced teleosts. The exposed part of the scale has tiny tooth-like projections (cteni).
John Harrison of JH Guide Service said he supports a reduction in the daily limit on crappie at Arkabutla, Enid, Sardis and Grenada lakes, but feels more needs to be done to protect the fisheries.

They enjoy heat, but do not like direct sunlight – they typically live in deeper water, but will linger near the water surface in the morning to stay warm. [6] Bluegill are usually found in schools of 10 to 20 fish, and these schools will often include other panfish, such as crappie, pumpkinseeds, and smallmouth bass. [13]
An earthworm is a soil -dwelling terrestrial invertebrate that belongs to the phylum Annelida. The term is the common name for the largest members of the class (or subclass, depending on the author) Oligochaeta. In classical systems, they were in the order of Opisthopora since the male pores opened posterior to the female pores, although the ...
