Occurrence: native
Salinity: freshwater
Abundance: fairly common (chances are about 50%) | Ref: Page, L.M. and B.M. Burr, 2011
Importance: minor commercial | Ref: Scott, W.B. and E.J. Crossman, 1973
Aquaculture: | Ref:
Regulations: | Ref:
Uses: live export: yes;
Comments: Ranges from Quebec to Nova Scotia; rarely caught as a game fish (Ref. 52559). A popular fish sold in live fish markets. Found in 2 out of 6 live fish markets near the Lakes Erie and Ontario (Ref. 53249). Fairly common, but less so than before due to pollution of major spawning grounds (Ref. 86798). Also Refs. 2850, 5723, 6885, 7251. Status of threat: 1). Bay of Fundy population: threatened. Criteria: 1; 2). Southern Gulf of St. Lawrence population: threatened. Criteria: 1; 3). St. Lawrence Estuary population: possibly extinct. Criteria: 1 ( (Ref. 81264). Introduced in Pacific Coasts of USA, and occasionally recorded from British Columbia waters (Ref. 5723).

Biology     Glossary (e.g. epibenthic)

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).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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).
