dc.description.abstract | 1. This study was based on statistics of gill net caught halibut landed
at Øksfjord, West Finnmark from 1955 to 1965. For the most recent
years some data on relative effort and weight distribution of the
catches were also available.
2. Small annual fluctuations in size distribution of the catches occurred,
but no consistent trend over the years were apparent.
3. During the 10 year period studied, halibut landings in the last quarter
of the year decreased markedly both in the county of Finnmark as
a whole and at Øksfjord. However, during the same period catch
per unit of effort in the gill net fishery increased greatly, and consequently,
the estimated total effort was very much reduced.
4. It is concluded that the reduced landings resulted mainly from
reduced fishing effort while the increase in catch per unit of effort
was partly caused by improved fishing nets and less competition on
the fishing grounds, but was also reflecting a real increase in fish
density. | |
