A stripping method for Atlantic halibut (Hippoglossus hippoglossus L.)
(ICES CM Documents;1987/F:40, Working paper, 1987)A stripping-board was built and tested on a broodstock of halibut ranging from 8 to 150 kg body weight. The smooth surface of the neophrene mattress minimized the loss of mucus and reduced the stripping stress ... -
An ICES workshop on biological effects in pelagic ecosystems (BECPELAG): summary of results and recommendations
(ICES CM Documents;2002/X:13, Working paper, 2002)During and after three previous workshops, biological effects methods have been compared and refined. The first was held in Oslo in 1988, the second at Bermuda in 1990, and the third in Bremerhaven in 1992. All three ... -

Atferdsbasert seleksjon i reketrål: Forsøk med MS ”Fangst” i Lyngenfjorden i Troms november 2005
(Rapport fra havforskningen, Working paper, 2007-11)I et prosjekt finansiert av Norges forskningsråd er formålet å utvikle et alternativ til ristsortering for utsortering av fisk i reketrål. Prosjektideen er å utnytte forskjeller i atferd mellom fisk og reke til å utforme ... -
Causes of variation in carcass traits of Atlantic salmon (Salmo salar)
(ICES CM Documents;1984/F:25, Working paper, 1984)The aim of the present study was to reveal causes of variation in carcass traits of farmed Atlantic salmon (Salmo salar). During slaughtering of one year class Atlantic salmon, composed of half sib and full sib groups, ... -
Coincidence echo statistics
(ICES CM Documents;1994/B:40, Working paper, 1994)Two scatterers at similar range give an echo which may appear to be due to a single scatterer. Methods for determining target strength that depend on resolving single scatterers may fail in this instance. Statistics associated ... -
Effects of fishing strategy on relative selectivity in trawls, longline and gillnets
(ICES CM Documents;1996/B:23, Working paper, 1996)Exploitation of fish stocks is dependent on effort, catchability, the selectivity of the gear used, and the fishermen's choice of time and place. A full-scale fishing experiment was conducted in February 1996 at the coast ... -

Habitat choice by marine zooplankton in a high-latitude ecosystem
(Journal article; Peer reviewed, 2008-07-29)According to habitat choice theory, zooplanktonic prey should choose a depth habitat that maximizes food intake while minimizing predation risk. Body size affects competitive ability and vulnerability in zooplankton, ... -
Joint Russian-Norwegian selectivity experiments on cod (Gadus morhua L.) in the Barent Sea, 1995
(Fisken og havet, Research report, 1996)With reference to point 4.3.2 in the protocol from the 23rd Session of the Mixed Norwegian- Russian Fisheries Commission, the parties agreed that necessary testing of sorting grids systems had to be performed during 1995 ... -
Overleving av torskefisk som unnslipper fra reketrål med Nordmørsrist
(Fisken og havet, Research report, 1995)The survival of one year old cod (Gadus morhua), haddock (Melanogrammus aeglefrzus) and whiting (Merlangius merlangius) escaping from a shrimp trawl with a metal grid sorting device (the Nordmøre grid) was studied during ... -
