Ecology Summary - Eleginus gracilis

Language:

Main Ref.	Maksimenko, V.V., 1985
Remarks	Occurs in shallow coastal waters (Ref. 1371). Enters rivers and may go considerable distances upstream, but usually remaining within regions of tidal influence (Ref. 1371, 27547). Adults exhibit seasonal movements: inshore during winter for purposes of spawning and offshore during summer for feeding (Ref. 1371). Juveniles and adults are opportunistic epibenthic feeders; juveniles feed on fish and small benthic crustaceans (Ref. 1371).
