पृष्ठीय रीढ़ (सम्पूर्ण) : 1; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 47 - 54; गुदा कांटा: 0; ऐनल सौफट रेज़: 37 - 41. Head large, about 30% of SL . Pectoral fins long, reaching origin of anal fin. Overall color is silvery, somewhat brownish on back, whitish on belly.
Abundant on sandy grounds and strays into shallower waters. A voracious predator with cannibalistic habits. Individuals over 40 cm TL prey on fishes such as gadoids and herring, while smaller ones feed on crustaceans, i.e. euphausiids and pandalids; food also includes gaspereau, myctophids, smelt, silversides, mackerel, sand lance, butterfish, snakeblennies, longhorn sculpins and squids (Ref. 5951). The smallest specimen feeds mostly on crustaceans (Ref. 58452). Exhibits seasonal onshore-offshore migration (Ref. 9988). Spawning takes place from June-July in the mid-Atlantic region; July-August in the Gulf of Maine and to the north of Georges Bank, and August-September on the Scotian Shelf (Ref. 58452). Marketed fresh, smoked and frozen; fresh fish are exported to European markets; eaten fried, broiled, microwaved and baked (Ref. 9988).
Spawning appears to be strongly influenced by water temperature, and annual variations occur both in the peak and the range of the spawning period, which may influence considerably the growth of juveniles.
