Spawning grounds of the Arcto-Norwegian cod outside Vestfjorden. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
Abstract
The spawning area of the Arcto-Norwegian cod is vast, extending
from 62 degrees N to 74 degrees 30'N in the area investigated.
Localities characterized by an intensive rate of spawning
are in the Norwegian Sea over the Langgrunnen, Buagrunnen,
Halten, Røst, Vesterålen, Andøy, Malangen and Fugløy Banks, in
the shelf slope area and in the open sea over great depths. The
position of spawning grounds and the intensity of spawning in
the area vary from year to year.
Various positions of spawning grounds are grouped into three
types: Type 1 - the main spawning grounds are only in the areas
of banks near the shore; Type 2 - spawning grounds are both in
the areas of banks and in the shelf slope area; Type 3 -
spawning grounds are outside the Norwegian Sea shelf and over
the Malangen Bank.
The position of spawning grounds in the survey area outside
the Vestfjorden is not an indicator of the abundance of year
classes of the Arcto-Norwegian cod.
