Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 90 - 116; Spine anali: 0; Raggi anali molli: 80 - 96; Vertebre: 50 - 54. Dorsal origin above middle of upper eye. Caudal imperfectly rounded.
Adults occur on mud bottom (Ref. 2850). They move into deep water in winter (Ref. 2850). Produce large amounts of slime which may cover other fishes when caught in trawls (Ref. 4925). Marketed as mink food (Ref. 4925) or as fillet (Ref. 2850).
