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 ... -
Survey design and analysis procedures: a comprehensive review of good practice
(ICES CM documents, Working paper, 1991)This paper provides a major review of acoustic survey and-data analysis procedures, it has been prepared as a result of discussions in the FAST working group of ICES. A review of published literature is combined with an ... -

Can the precision of bottom trawl indices be increased by using simultaneously collected acoustic data? The Barents Sea experience
(ICES CM documents, Conference object, 2006) -
An object-based approach to integration of software to support management and reporting of marine ecosystem survey data
(ICES CM documents, Working paper, 2006)An object-based software to support distributed databases and data reporting from combined fisheries and environmental surveys is presented. The key abstraction of this system is expressed as a generic station (data) object. ... -
Fish migration in oscillating stratified water masses
(ICES CM documents, Working paper, 2006)Abstract Time series records from data storage tag (DST) attached on Northeast Arctic cod (Gadus morhua L.) and Greenland halibut (Reinhardtius hippoglossoides) are investigated in connection with hydrodynamic and ... -
Measuring uncertainty in trawl surveys: implementation in DATRAS
(ICES CM documents, Working paper, 2006)Abstract The basic data from several ICES coordinated trawl and beam trawl surveys in the Baltic Sea, the North Sea, the area west of Scotland and France are stored in the DATRAS database in the ICES Secretariat; every ... -
Eco-genetic models: a new framework for understanding fisheries-induced evolution
(ICES CM documents, Working paper, 2006) -
Harvest control rules and changing productivity: the working example of North Sea herring
(ICES CM documents, Working paper, 2006)North Sea herring is managed by the EU and Norway through a harvest control rule where target fishing mortalities are changed if the estimated SSB falls below a trigger biomass million tonnes). This management agreement ... -
An ecosystem modeling approach to predicting cod recruitment
(ICES CM documents, Working paper, 2006)Abstract The NORWECOM ocean model system implemented with the ROMS ocean circulation model has been run to simulate conditions over the last 25 years for the North Atlantic. Modelled time series of volume fluxes, primary ... -
Feeding and vertical distribution of cod larvae in relation to availability of prey organisms
(Conference object, 1979)The year-class strength of the Arcto-Norwegian cod stock varies on an annual basis by a factor of about 20:1 and is determined at the 0-group stage (about 1/2 year old cod). Since the number of eggs spawned far exceeds the ... -

Can trawling effort be identified from satellite-based VMS data?
(ICES CM documents, Working paper, 2006)Data from satellite-based vessel monitoring systems (VMS) can, in principle, be used to measure fishing effort with a high spatiotemporal resolution. However, it can be difficult to separate between fishing activity and ... -
The Norwegian in-year monitoring fishery for sandeel in the North Sea using satellite-based VMS data and landings information
(ICES CM documents, Working paper, 2006)Due to the critically poor status of the sandeel stock in the North Sea, the Norwegian Ministry of Fisheries and Coastal Affairs decided to conduct a monitoring fishery in April/May 2006 with a limited number of Norwegian ... -
Norwegian investigations on young cod and haddock in the Barents Sea during the winter 1982
(ICES CM documents, Working paper, 1982)An acoustic survey and a bottom trawl survey were carried out in the Barents Sea during winter 1982. Both surveys showed that there has been a reduction in the total number of cod of about 50% and about 75% for haddock in ... -
