| Summary: | The effect of the Lofoten purse-seine fishery is considered. Both biological and fishery statistical data are used, and the main features of this analysis are the following: The difference between the length distributions of the purse-seine and the long-line catches have during 1950-1953 decreased year by year. In 1954-1958 the length distributions have been similar, but in 1959, 1961 and 1962 the purse-seine has again exploited the bigger and older fish to a greater extent than long-line. 2. The purse-seiners may in some years have interfered with each other, causing a reduction in their fishing power. 3. The activity of the purse-seiners have not reduced the catch of the boats fishing with the other gears.
