Measurements of the density coefficient and average target strength of herring using purse seine.
(ICES CM Documents;1982/B:33, Working paper, 1982)Integrator values were obtained from a school of herring. The fish density of this school was determined on the basis of a purse seine catch. From these values a conversion factor and average target strength for herring ... -
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 ... -
Merking av rusefanget torsk i områdene Smøla-Helgeland
(Fisken og havet;1964 - Nr. 2, Journal article, 1964)The recaptures of trap net caught cod tagged during January and February 195G and 1957 and November 1957 in different localities along the Norwegian Coast (Fig. l) have been studied. On the tagging localities the cod migrate ... -

Methods of index calculation and presentation of fish abundance data using standard computer programs
(PINRO-IMR Symposium, Conference object, 1995)Standard 0-group indices distribution maps are now produced based on hand-drawn maps using AutoCad with some additional procedures. This paper briefly describes the mathod. The paper further describes ways of importing ... -

Modeling fish reaction to vessel noise, the significance of the reaction thresholds
(ICES CM documents, Working paper, 2001)A simple model of fish reaction to vessel noise is made. The fish are assumed to swim directly away from the noise source. The main noise source is assumed to be the propeller. Parameters for endurance and swimming speed ... -
Modelling Diurnal Variation in Bottom Trawl Catches and Potential Application in Surveys
(ICES CM documents, Working paper, 1999)Diurnal variability in bottom trawl survey catches may influence the quality of the survey results when not taken properly into account. This is especia]!.y the case if diurnal effects vary substantiaIly from year to ... -
More on the frequency dependence of target strength of mature herring
(ICES CM Documents;1993/B:30, Working paper, 1993)The hibernating stock of Norwegian spring-spawning herring has been acoustically surveyed in a fjord system in northern Norway in December 1992. The survey frequencies are 18, 38, 120, and 200 kHz. When the corresponding ... -
Mortality and injuries of haddock (Melanogrammus aeglefinus) that are caught by pelagic longline
(ICES CM documents, Working paper, 2002)By-catches of haddock (Melanogrammus aeglefinus) below legal size (44 cm total length) in the seasonal pelagic longline fisheries for haddock off the coast of Finnmark, northern Norway, are often high. The small fish are ... -
Mortality and injuries of haddock, cod and saithe escaping through codend meshes and sorting grids
(ICES CM documents, Working paper, 2002)Mortalities and injuries of the gadoids haddock (Melanogrammus aeglefinus L.), cod (Gadus morhua L.) and saithe (Pollachius virens L.) were studied after codend and grid escapement in two full scale trials in 2000 and 2001 ... -
Multisampler - a new tool for use in sampling trawls
(PINRO-IMR Symposium, Conference object, 1997)The MultiSampler is a system to be mounted in sampling trawls to give better estimates and knowledge about fish stocks.The system is remotely controlled via a hydroacoustic link from the vcssel. It consists of a rigid ... -

NEA saithe XSA runs with different survey tuning series
(Working paper, 2010-02)New tuning series from a combined and improved survey gives lower and more stable S. E. Log q residuals than the tuning series presently used. However, the retrospective trend is still poor and the estimates of F and SSB ... -
