IMR status report on the Barents Sea Ecosystem, 2004-2005
(Working paper, 2005) -
IMR/PINRO update of the “Joint Norwegian-Russian environmental status report on the Barents Sea Ecosystem”
(IMR/PINRO Joint Report Series;1/2014, Research report, 2014) -
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 vitro toxicity of hydrocarbon pollutants

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 ... -

Including climate into the assessment of future fish recruitment, using multiple regression models.
(ICES CM documents, Working paper, 2005)Climate variability has generally not been included in the assessment of fish stocks in the Barents Sea and Norwegian Sea. However, in recent years there has been a focus on implementing climate variability in the assessment ... -
Incorporating experimentally derived estimates of survey trawl catchability into the stock assessment process
(ICES CM Documents;1997/W:5, Working paper, 1997)During the course of the April, 1996, meeting of the Fishing Technology and Fish Behavior Working Group it became clear to many that the methodology for experimentally estimating the catchability of survey trawls might ... -
Increased growth rate in Atlantic salmon parr by using a two-colour diet
(ICES CM Documents;1985/F:17, Working paper, 1985)Fishes hunting by sight are known to pay a cost of confusion when faced with high densities of uniform food particles. In such instances, awareness of other stimuli reduces feeding efficiency such that the fishes prefer ... -
Incubation of halibut yolk sac larvae improved by addition of freshwater and oxygen
(ICES CM Documents;1998/L:14, Working paper, 1998)Halibut fry has been produced regularly by scientific and commercial institutions since late 80- ties. The yearly number of halibut fry produced have, however, not fulfllled the optimistic expectations. This could partly ... -
Indication of high natural mortality for juvenile herring from acoustic and tagging data.
(ICES CM Documents;1980/H:62, Working paper, 1980)Natural mortality for juvenile herring (Norwegian Spring spawners) is discussed on the basis of following data: 1. Acoustic estimates of the 1975 and 1976 yearclasses of herring as 0-group and estimates from tagging ... -
Individual based spatial models with evolved fish behaviour
(ICES CM Documents;1998/J:16, Working paper, 1998)Due to spatial heterogeneity, the survival and growth of fishes depend upon their habitat. For mobile pelagic fishes, it hence becomes important to analyse the factors responsible for spatial dynamics in order to understand ... -
