Ecology Summary - Sebastes mentella

Language:

Main Ref.	Konchina, V.Y., 1986
Remarks	Inhabit deep waters (Ref. 4570). Epibenthic-pelagic (Ref. 58426). Bear live young. Gregarious throughout life. Feed on euphausiids, hyperiids, cephalopods, chaetognaths and small fishes. Longevity was determined from isotope ratios and given as at least 65 years in general and at least 75 years in the waters off Nova Scotia (Ref. 45673). Preyed upon by Atlantic halibut, Atlantic cod, swordfish and harbor seals. Parasites of the species include nematode, cestodes, trematodes and copepod (Ref. 5951).

Association remarks	Identified divergence of behavioural groups into depth-defined adult habitats; reference to common nursery habitats and spawning groups in areas with developing females (Ref. 94923). Previously described spawning migration pattern derived using morphometrics indicating structured reproductive aggregation (Ref. 94931).
