Ecology Summary - Pomoxis nigromaculatus

Language:

Main Ref.	Turner, J.L., 1966
Remarks	Inhabits lakes, ponds, sloughs, and backwaters and pools of streams. Usually occurs among vegetation over mud or sand, most common in clear water. Forms schools (Ref. 1998). Feeds early in the morning, from midnight to 2 am (Ref. 1998). Individuals up to 16 cm feed on planktonic crustaceans and free-swimming, nocturnal, and dipterous larvae; larger individuals feed on small fishes (Ref. 1998). May be preyed upon by other fishes (Ref. 1998).
