A pairtrawl survey was carried out in the Norwegian Sea during
July - August 1991 to map the distribution of pelagic fish.
Herring were caught throughout most of the surveyed area, with
the largest concentrations observed within 200 nautical miles
off Vesterålen/Troms. It therefore seems that the Norwegian
spring-spawning herring has resumed its oceanic feeding
migration. Mackerel were observed in most parts of the
surveyed area as far north as 73° N, and seemed to belong to
the Western stock. It was observed a tendency for older and
bigger mackerel of the same yearclasses to migrate further
north than younger and smaller individuals. A similar tendency
was observed for horsemackerel.
