أحياء     المصطلحات (على سبيل المثال epibenthic)

Inhabits lakes and slow-flowing areas of small to medium rivers. Common around vegetation (Ref. 86798). Forms schools. Can withstand brackish waters for a limited period (Ref. 1998). Newly hatched individuals school near the shore, moving into deeper water in the summer (Ref. 4569). Feeds mainly on aquatic insects and its larvae and some terrestrial insects (Ref. 10288); but also on planktonic crustaceans, mollusks, and small fishes (Ref. 1998). Preyed upon by fish-eating birds and mammals (Ref. 1998). Utilized as game fish and as food in the past (Ref. 1998).

Life cycle and mating behavior Maturities | التكاثر | Spawnings | Egg(s) | Fecundities | Larvae

Spawning fish come close to shore in groups of 50-400. Groups are about 25 to 100 feet apart from each other. Females are crowded by 2 or more males into 1 or 2 inches of water by the shoreline and eggs and sperms are released.
