Ecology Summary - Alosa pseudoharengus

Ngôn ngữ:

Thông tin chủ yếu	Whitehead, P.J.P., 1985
Các chú thích	Euryhaline, entering brackish- and freshwaters, anadromous (Ref. 10294). Movement of schooling adults apparently restricted to coastal areas proximal to natal estuaries (Ref. 4639). They migrate up rivers and even small streams to spawn in lakes and quiet stretches of rivers, then return to sea shortly after spawning (Ref. 4639); landlocked populations also ascend affluent rivers and streams. Larvae remain in vicinity of spawning grounds, forming schools at sizes less than 10 mm TL, within one to two weeks after hatching (Ref. 4639), then descend in summer and autumn or even as late as November or December. Feed on shrimps and small fishes; the young on diatoms, copepods and ostracods while in rivers. Feed on planktonic and benthic invertebrates (Ref. 13515). Fish measuring 5.0-7.0 cm TL feed by gulping, filtering and particulate feeding, whereas smaller fish are exclusive particulate feeders (Ref. 46977). Preyed upon by walleye, smallmouth bass, crappie, rainbow trout and ohrid trout (Ref. 10294).
