A model simulating the effect of sampling strategy on stock assessment of gadoids in sub-areas I and II
(ICES CM Documents;1986/G:69, Working paper, 1986)In the northeast Atlantic, management advice for fisheries is usually based on Virtual Population Analysis, yield per recruit, and predictions of catch and biomass. For these calculations, age distributions and weigth-at-age ... -
Compilation of the gadoid data collected during the international herring survey 1976
(ICES CM Documents;1976/F:20, Working paper, 1976) -
Development of a species-selective trawl for demersal gadoid fisheries
(ICES CM Documents;1995/B+G+H+J+K:1, Working paper, 1995)An experiment was carried out to test a prototype species-selective bottom trawl for separating cod from haddock, secondarily saithe, in the Norwegian commercial roundfish fisheries. A sorting system incorporating a ... -
Habitat selection and competition amongst 0-group gadidae off Mid-Norway
(Working paper, 1988)Juvenile gadids and other co-occurring fishes were collected during August in the years 1981 to 1983 at the Møre coast (Mid-Norway). The gears used were pelagic trawl, bottom trawl, Danish seine and beach seine. All species ... -
Inter- and intraspecific variations in hemoglobins of some gadoid fishes
(ICES CM Documents;1967/F:24, Working paper, 1967) -
Monitoring changes in abundance of gadoids with varying availability to surveys
(ICES CM Documents;1991/G:76, Working paper, 1991)The use of scientific survey data for assessing abundance of commercially important fish stocks has become a managerial necessity in many regions. Errors and bias in estimates from such surveys may thus have great economic ... -
Predicting recruitment of 0-group gadoids in the Barents Sea - critical interaction between models and observations
(ICES CM documents, Working paper, 2007)The most important gadoid fish stocks of the Barents Sea spawn along the coast of Norway. The eggs, larvae and juveniles are transported northwards with the oceanic coastal currents from the spawning grounds towards their ... -
Preliminary report from a comparative study of the diet of four gadoid fishes in a fjord of western Norway
(ICES CM Documents;1986/G:71, Working paper, 1986)As a contribution to a research program on sea ranching of cod in a fjord in western Norway, a dietary analysis of the main gadoid species has been conducted. The main aim of the analysis has been to identify potential ... -
Preliminary report of the North Sea roundfish working group : Effect of Recommendation 2 Fisheries on the Gadoid Stocks

The results of the international 0-group gadoid survey in the North Sea 1979 and of an 0-group Gadoid survey to the west of Scotland.
(ICES CM Documents;1979/G:36, Working paper, 1979)The survey was carried out in the period 13 June to 5 July by 4 vessels, CORELLA (England), EXPLORER (Scotland), JOHAN HJORT (Norway) and TRIDENS (The Netherlands). The gear used, the design of the experiment and the ... -
