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 ... -

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, ... -
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 ... -

Sammenligning av fangsteffektiviteten til fiskeredskaper
(Fisken og havet, Research report, 2002)A method to determine the catching efficiency of one fishing gear relative to another is presented in this manual. The principle is to perform a number of paired comparisons between two gears by conducting catching ... -
Selective mecanisms of significance in the survival of fish
(Fisken og havet, Research report, 1995)The adult fish can during the reproductive process select for three different parameters; 1- time of spawning, 2- location of spawning, and 3- egg size. In this work all three parameters are discussed, but particular ...
