Inhabit coastal waters and are commonly found in bays but may enter rivers in the spring to spawn (Ref. 2850). Some populations are landlocked (Ref. 7251). Voracious and opportunistic feeder (Ref. 5951). Larvae feed on zooplankton; juveniles take in small shrimps and other crustaceans, annelid worms, and insects (Ref. 1998, 10294); adults feed on a wide variety of fishes (alewives, herring, smelt, eels, flounders, mummichogs, rock gunnels, sand lance, silver hake and silversides (Ref. 5951)) and invertebrates (squid, crabs, sea worms and amphipods (Ref. 5951)), mainly crustaceans (Ref. 1998). Feeding ceases shortly before spawning (Ref. 1998). Utilized fresh and eaten broiled and baked (Ref. 9988).
Move into fresh or brackish water to spawn (Ref. 39467). Females spawn more than once in a season, but they don't necessarily spawn every year (Ref. 1998).
