Estimates of towing time in surveys
(ICES CM documents, Working paper, 2002)To decide the start and stop time for a survey haul the current method used in Norwegian sampling are the data from the door sensors and height sensors of the trawl. When the trawl has achieved its right geometry, the start ... -
Estimating catch-at-age from market sampling data using a Bayesian hierarchical model
(ICES CM documents, Working paper, 2001) -
Estimation of theoretical operating time in the Antarctic whaling
(ICES CM Documents;1965/175, Working paper, 1965) -
Estimators in acoustic surveying of fish populations
(ICES CM Documents;1976/B:36, Working paper, 1976) -
Evaluation of candidate management plans, with reference to North-East Arctic Cod
(ICES CM documents, Working paper, 2003)We here discuss the scope, nature and quality standards of simulation models that may be used in order to evaluate proposed or candidate management plans, including their parameters (reference points). A recently proposed ... -
Evaluation of harvest control rules: simple one-parameter vs. complex multi-parameter strategies
(ICES CM documents, Working paper, 2003)Harvest control rules (HCR) are sets of well-defined rules that can be used for determin-ing annual fish catch quotas. If a management policy can be expressed as a HCR, then the HCR provides means to determine the total ... -
Experimental dumping of waste ferrosulfate (copperas) into the Skagerrak
(ICES CM Documents;1971/E:32, Working paper, 1971) -
Experiments on tagging mortality and shedding in captive Norwegian spring spawning herring: effects of tagging season and tag type
(ICES CM documents, Working paper, 2001) -
Factors influencing tag-recovery rates in the Norwegian spring-spawning herring tagging scheme
(ICES CM documents, Working paper, 2001) -
Field methods for fish behaviour studies used in Norway
(PINRO-IMR Symposium, Conference object, 1997) -

FiSHU@LiS, a Computer Game on a General Pelagic Fish
(ICES CM documents, Working paper, 2003)Experience has shown that making political decisions that ensure sustainable use of natural resources is difficult. This has raised the question on how to include stakeholders and citizens in decision processes. ViRTU@LiS ... -
A Framework for Communicating Qualities of Indicators
(ICES CM documents, Working paper, 2003)There is a growing focus on ecosystem-based indicators and what qualities they need to satisfy. However, the qualities and the characteristics of the already existing indicators vary substantially. Due to both scientific ... -
Growth of northeast arctic cod in relation to ambient temperature
(ICES CM documents, Working paper, 1996)In the present study temperature related changes in horizontal distribution are described and the influence of temperature on the growth of Northeast Arctic cod is interpreted. Data from acoustic-and bottom trawl surveys ... -
Harbour seal Phoca vitulina habitat use and interactions with fisheries as explored by a combined GIS and population energetics model
(ICES CM documents, Working paper, 2000) -
How does stochasticity affect evolutionary regime shifts in age and size at maturation?
(ICES CM documents, Working paper, 2006)Fish in many exploited stocks grow faster and mature earlier at either larger or smaller sizes in comparison to pre-exploitation periods. These changes can be driven by both genetic and phenotypic responses. We have shown ... -
ICES working group on grey seals : Report of first meeting, 16 - 20 May 1977, Cambridge, UK
(CES CM Documents;1977/N:11, Working paper, 1977) -
Impact of herring spawning behaviour on acoustic abundance estimates
(ICES CM documents, Working paper, 2001)Spawning dynamics of Norwegian spring spawning herring was studied in south western Norway 29 March to 3 April 2000 using hydroacoustics. The horizontal distribution of the spawning layers shifted in a south-easterly ... -
In situ fish target strengths derived with a split-beam echo sounder
(ICES CM documents, Working paper, 1985)In-situ target strengths of six fishes were determined with a split-beam echo sounder during cruises about Lofoten in March 1984 and the Shetland Islands in July 1984. The species and lengths, mean and standard deviation, ... -
In situ observations of swimbladder compression in herring
(ICES CM documents, Working paper, 1984)The hydrostatic function of the swimbladder in herring is experimentally investigated through in situ diver-assisted measurements of swimbladder volume on net-caught and caged fish. In agreement with morpho-physiological ...
