Body shape (shape guide): short and / or deep.
Common in shallow water on soft, silty bottom. Moves into shallow water in summer and to deeper water in winter (Ref. 6885). Spawning adults exhibit north-south migrations (Ref. 6885). Feeds on chaetopod marine worms, young herring, shrimps, and sand dollars (Ref. 6885). A tasty food fish, sometimes marketed (Ref. 2850). Also used for mink food (Ref. 2850).

Trophic level (Ref. 69278) |
3.6 ±0.54 se; based on food items. |
| Generation time | 4.2 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies. |
