Saithe tagging experiments in northern Norway north of 68°N, 1970 - 74.
(ICES CM Documents;1978/G:34, Working paper, 1978)From 1970 to 1974, 7913 saithe were tagged and released along the coast of northern Norway from north of 68 N and eastwards nearly to the border between Norway and the USSR. -

Saithe tagging experiments on the Norwegian west coast south of 62°N, 1972 - 74.
(ICES CM Documents;1978/G:32, Working paper, 1978)From 1972 to 1974, 6291 saithe were tagged and released on the Norwegian west coast between 59 N and 62 N. Before 1972, only 40 saithe have been tagged in the area, in 1956 and 1959, and these experiments were not extensive ... -
Sampling Atlantic salmon in the NE Atlantic during summer: methods of capture and distribution of catches
(ICES CM Documents;1996/M:12, Working paper, 1996)In July/ August 1991 the Institute of Marine Research (IMR, Norway) performed a pairtrawling (two boat trawl) experiment with a surface trawl to catch young herring in the northem Norwegian Sea. 34 postsmolts and two 1- ... -
Sampling herring in the Norwegian Sea by pelagic trawl
(ICES CM Documents;1997/W:21, Working paper, 1997)When the stock of Norwegian spring-spawning herring is distributed in the Norwegian Sea in summertime, pelagic trawl sampling may be rather challenging because of substantial variation in vertical distribution (from ... -
Second Report of the EEC - Norwegian Joint Scientific Group on Migration and Area Distribution of Mackerel (western stock) [Brussel, 12- 13 December, 1989]
(ICES CM Documents;1990/H:5, Working paper, 1990) -
Shrimp investigations in the Norwegian deep 1984 -1985
(ICES CM Documents;1985/K:5, Working paper, 1985)Systematic investigations for assessment of the stock of Pandalus borealis in the Norwegian Deep were started in 1984. The program includes a yearly cruise with research vessel. From commercial trawlers samples and logbooks ... -
Size and age composition of the Norwegian purse-seine catches in the North Sea and the Skagerak

Size and exploitation of the mackerel stock in the Skagerrak and North-Eastern North Sea

Size distribution of the edible crab (Cancer pagurus) and catch/effort in the crab fishery at one locality in Norway during 1972-1974

Size-selection of mackerel and saithe in purse seine
(ICES CM Documents;1994/B:28, Working paper, 1994)In purse seine fisheries, there may exist potentials for size selection because some of the fish in the catch are less than the legal size, and because different size groups are paid differently. Both potentials are ... -
Some comments to the problem of adjusting TACs to mesh size changes.
(ICES CM Documents;1979/G:56, Working paper, 1979)Mesh assessments are usually carried out by calculating "short term losses" and "long term gains" expected from a change in the minimum legal mesh size, assuming no change in total fishing effort or its distribution by ... -
The spurdogs in the North Sea area in the Norwegian fishery and observations on changes in migration pattern.
(ICES CM Documents;1980/H:60, Working paper, 1980)The Norwegian fishery of spurdog (Squalus acanthias L.), which started in 1930, has played a dominant part in the fishery for this species in Europe. During 1963-1968 a change occured in the behaviour of the spurdog ... -

Stock prediction using stochastic recruitment numbers with empirical stock-dependent distribution
(ICES CM Documents;1991/H:28, Working paper, 1991)Probability distributions for the recruitment, conditional on the spawning stock biomass (SSB) were made using a kernel method. Predictions were made with recruitments according to these distributions for 10 years, using ... -
