Impact of grazin from capelin (Mallotus villosus) on zooplankton: a case study in the northern Barents Sea in August 1985
(ICES CM Documents;1991/L:62, Working paper, 1991)The distribution of capelin was mapped in the area east of Hopen. Zooplankton was sampled with Juday net and 1m^2 MOCNESS sampler, and analyzed with respect to hydrography and capelin abundance. The capelin "front" ... -
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 ... -
Impact of size-selective mortality on waterfleas (Daphnia)
(ICES CM Documents;2010/M:25, Working paper, 2010)Size‐selective predation shapes species and induces changes in life‐history traits. Exposure to sizeselective mortality will make being the size that is vulnerable dangerous and possibly fatal; thus, if small individuals ... -
Implications of fisheries-induced evolution for stock rebuilding and recovery
(ICES CM documents;2010/M:29, Working paper, 2010)Fishing-induced evolution has the potential to change life-history and other characters of exploited stocks. Here we study the rebuilding and recovery of an exploited stock with en individual-based eco-genetic model ... -
Import of furunculosis to Norway with Atlantic salmon smolts from Scotland
(ICES CM Documents;1987/F:8, Working paper, 1987)In early summer 1985 the Norwegian Veterinary Authorities authorized the import of about 250.000 Atlantic salmon smolts from a fish farm at the west coast of Scotland to the Namdal region north of Trondheim. Immediately ... -

Improved catch rates and selection of Norway lobster (Nephrops norvegicus L.) by controlled release of fluid bait extract in pot fishing
(ICES CM Documents;1992/B:14, Working paper, 1992)The effect of controlled release of fluid mackerel extract as bait in Norway lobster pots was tested in comparative fishing trials. Compared with natural mackerel bait, pots with extract release rates above 6 ml/h had ... -
Improving the link between science and management: Drawing upon local fishers' experience
(ICES CM Documents;1994/T:20, Working paper, 1994)Norwegian fish stock assessment has not included estimation of coastal and fjord resources until recently. The geographical area varies both in environmental and biological features. Stock assessment is especially difficult ... -

In situ determination of bottom trawl ground gear contact
(ICES CM documents, Working paper, 2001)Exact definition of towed distance with proper ground gear contact is an essential parameter in bottom trawl swept area estimates of fish abundance. Errors in this key parameter may lead to a first order bias in abundance ... -
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 ... -
In situ of Cape horse mackerel (Trachurus capensis)
(ICES CM Documents;1999/J:4, Working paper, 1999)The acoustical target strength (TS) of Cape horse mackerel (Trachurus capensis) was measured in situ at 38 kHz using a submersible split beam transducer in combination with a SIMRAD EK 500 echosounder. The transducer ... -
In situ target strength observations on haddock
(ICES CM Documents;1986/B:39, Working paper, 1986)In situ target strength measurements of ideally resolved haddock have been made using the ES-400 split-beam echo sounder. The measurements are compared with the mean target strength obtained simultaneously by counting ... -
In vitro ecotoxicological assessment of pelagic ecosystems
(ICES CM documents, Working paper, 2002)The ICES biological effects monitoring in pelagic ecosystems (BECPELAG) workshop is a multi-national, multi-disciplinary workshop aimed at establishing suitable techniques for monitoring the effects of contaminants on ... -

In/out-flow of coastal water in Vestfjorden
(ICES CM Documents;1978/C:51, Working paper, 1978)Hydrographic sections in Vestfjorden, Northern Norway, during winter 1977 showed strong horizontal temperature gradients on the west side of the fjord indicating an outflow of cold coastal water. Analysis of sea thermograph ... -
The inability of the 0-group saithe survey to forecast the strenght of the year-classes entering the fishery
(PINRO-IMR Symposium, Conference object, 1995)An 0-group saithe trawl survey was conducted annually in the Norwegian Sea and outside the Norwegian coast north of 62"N in April-May 1985-1992. The survey aimed at covering the distribution of 0-group saithe in the open ... -
Inclined water flow and its applications for reduced bycatch in shrimp trawls
(IMR/PINRO Joint Report Series, Conference object, 2001)The use of the Nordmøre grid in the Pandalus fishery has significantly reduced the bycatch of finfish. Grids operate on physical separation based on size to achieve bycatch reduction. However, problems arise when the size ...
