Comparative growth and survival of two genetic strains of Atlantic cod (Gadus morhua L.) reared through the early life stages in a marine pond in western Norway
(ICES CM Documents;1990/F:48, Working paper, 1990)The investigation was carried out in a marine pond in western Norway during spring and summer 1990. Two genetic defined strains of Atlantic cod (Gadus morhua L.) were used as broodstocks. A total of 11.1 x 10^6 cod larvae ... -
Comparative growth studies of salmonids
(ICES CM Documents;1975/M:21, Working paper, 1975) -
Comparative growth studies, II
(ICES CM Documents;1976/E:36, Working paper, 1976)Atlantic salmon smolts of Norwegian and Swedish (Baltic) origin and rainbow trout fingerlings were stocked in floating pens at several farms along the Norwegian coast. The fish were counted, measured and weighed with approx. ... -
Comparative habitat use and foraging behaviour of harbour seals and grey seals in Western Norway
(ICES CM Documents;1995/N:1, Working paper, 1995)Adult harbour seals at Froan nature reserve, Central Norway, were tagged with VHF radio tags and depthvelocity, hart rate and stomach temperature sensors combined with ultrasonic transmitters. An automatic shore based ... -
Comparison between "underway" and "on station" acoustic measurements made during bottom trawl surveys
(ICES CM Documents;2002/J:3, Working paper, 2002)It becomes in many cases, routine, to collect acoustic data during bottom trawl surveys, both during and between trawls providing “on station” and “underway” acoustic data. Still, the combination of trawl and acoustic data ... -
Comparison Between Catch per Unit Effort in the Norwegian Gill-net and Purse-seine Fishery for Herring
(ICES CM Documents;1963/H:13, Working paper, 1963) -
Comparison of 4 Northern Hemisphere regions: Ecosystem responses to recent oceanographic variability
(ICES CM documents;2007/D:07, Working paper, 2007)Ecosystem responses to oceanographic variability resulting from recent climate changes are compared and contrasted for four high latitude regions of the Northern Hemisphere, two in the Pacific (Bering Sea and Gulf of Alaska) ... -
A comparison of egg quality and larval viability between cultured coastal cod and wild arcto-norwegian cod
(ICES CM documents;1991/F:41;, Working paper, 1991)Experiments on cod eggs revealed an inverse relationship between egg diameter and mortality. Further, larvae hatching from small eggs showed a redeuced feeding ability. Other methods to characterice larval viability ... -
Comparison of equal-area cylindrical and circular piston transducers
(ICES CM Documents;1994/L:29, Working paper, 1994)Design of sondes for in situ measurement of zooplankton or other scatterers requires choosing among alternative transducer geometries. This contribution addresses the problem of choosing between cylindrical and circular ... -
Comparison of Northeast Atlantic mackerel (Scomber scombrus) distribution patterns in the Norwegian Sea using lidar, sonar, and trawl
(ICES CM documents, Working paper, 2003)In July 2002 the Institute of Marine Research (IMR), Bergen mapped the distribution and density of mackerel in the Norwegian Sea using lidar, sonar and trawl. A major objective was to test the efficiency of the lidar as ... -
Comparison of Norwegian and Russian trawl performance: Preliminary analysis of cod data
(Working paper, 1998) -
Comparison of tags used on arctic cod
(ICES CM Documents;1959/80, Working paper, 1959) -
Comparison of the effect of dichlorvos and pyrethrins against salmon lice (Lepeophtheirus salmonis) parasitic on salmon (Salmo salar) by one or successive treatments
(ICES CM Documents;1994/F:21, Working paper, 1994)Experiments with a flower extract containing Pyrethrins generally used as an insecticide has been carried out at Austevoll Aquaculture Research Station since 1989. Different types of administration methods have been ... -
Comparison of the effects of forced errors in survey data between an age and an age-and-length structured model of Northeast Arctic Cod
(ICES CM documents, Working paper, 2004)It is known that many fisheries data sets contain several different sources of error. It is likely that models with different structures will, in general, be affected in different ways by these errors. It is therefore ... -
A comparison of the toggle and sphyrion methods of tagging the lobster (Homarus vulgaris L.)
(ICES CM Documents;1973/K:41, Working paper, 1973) -
Comparison of two 120-kHz split-beam transducers
(ICES CM Documents;1991/B:31, Working paper, 1991)The performance of two 120-kHz split-beam transducers is compared through the following measures: relative power level, directivity index, relative source level, and reverberation index or equivalent beam angle. Sidelobe ... -
Comparison of Uncertainty Estimates in the Short Term Using Real Data
(ICES CM documents, Working paper, 2000)In response to increased interest in the Precautionary Approach, various approaches have been applied to characterize the uncertainty of fisheries assessment projection results. Using three case studies, a comparison of ... -
A comparison of variability and bias when ageing Northeastern Atlantic minke whales (Balaenoptera acutorostrata) by counting growth layer groups in the mandible and bulla tympanica
(ICES CM documents, Working paper, 2001)The age of 43 minke whales (Balaenoptera acutorostrata) was estimated by counting growth layer groups (GLGs) GLGs in 500um thick haemotoxylin stained transverse sections of left and right mandible. The same whales were ... -
