Dorsale stekels (totaal) : 9 - 11; Dorsale zachte stralen (totaal) : 10 - 13; Anale stekels: 3; Anale zachte stralen: 7 - 13.

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).

Bayesian length-weight: a=0.00933 (0.00745 - 0.01169), b=3.06 (2.99 - 3.13), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trofisch niveau (Ref. 69278): 4.7 ±0.2 se; based on diet studies.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (K=0.12; tm=5-7; tmax=30; Fec=14,000).

Prior r = 0.31, 95% CL = 0.20 - 0.46, Based on 2 full stock assessments.

Fishing Vulnerability (Ref. 59153): High vulnerability (61 of 100).

Climate Vulnerability (Ref. 125649): High vulnerability (61 of 100).

Prijsklasse (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 14.4 [7.1, 30.8] mg/100g; Iron = 0.291 [0.146, 0.542] mg/100g; Protein = 19.4 [18.5, 20.4] %; Omega3 = 0.583 [0.331, 1.065] g/100g; Selenium = 16.5 [7.6, 34.2] μg/100g; VitaminA = 8.61 [2.38, 30.88] μg/100g; Zinc = 0.307 [0.217, 0.451] mg/100g (wet weight); based on nutrient studies.
