Intercalibration of acoustic systems onboard R/V "Johan Hjort" and R/V "Pinro"
(ICES CM Documents;1992/B:17, Working paper, 1992)Inter-ship calibration is a comparison between integrator output of two or more ships sailing over the same fish aggregations. Although it is a relative measurement, it is highly desireable whenever research vessels ... -
Internal tagging experiments of mackerel in the Skagerrak and the North-Eastern North Sea
(ICES CM Documents;1970/H:25, Working paper, 1970) -
Investigations on blue whiting in the area west of the British Isles, spring 1995
(ICES CM Documents;1995/H:7, Working paper, 1995)In March/April 1995 the fifth Norwegian-Russian joint acoustic survey on the blue whiting spawning stock was carried out. The shelf edge area to the west of The British Isles was covered by two vessels in a general ... -
Joint Report of the Study Group on Unaccounted Fishing Mortality (SGUFM) and the Workshop on Unaccounted Fishing Mortality (WKUFM)
(ICES CM documents, Working paper, 2005) -
Laboratory experiments with internal tagging of saithe
(ICES CM Documents;1977/F:22, Working paper, 1977) -
Lidar TS measurements on Northeast Atlantic mackerel (Scomber scombrus)
(ICES CM documents, Working paper, 2003)A green linearly polarized laser and a digital video camera were used to find the average reflectivity and lidar target strength of live mackerel. The light reflected from the fish was compared to that reflected from a ... -
Longline: Full scale trials with new hook designs and reduced size of bait

Marking experiments on the arctic cod
(ICES CM Documents;1958/74, Working paper, 1958) -
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 ... -
Mesh selection data of arctic cod and haddock : Report of G. O. Sars' cruise Sept.-Nov. 1957

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 ...
