Spatial and temporal patterns in recruitment of shrimp Pandalus borealis in the Barents Sea
(ICES CM documents, Working paper, 2000)The shrimp spawn in autumn and the eggs are carried as out roe by the females until spring when the larvae hatch. Within a period of 2-3 months the shrimp larvae settle to the bottom. Today’s assessment and forecast of ... -
Do two-year-old Arcto-Norwegian cod remain in the area where they settled?
(ICES CM documents, Working paper, 2001) -
Transport of Atlantic Water in the western Barents Sea
(ICES CM documents, Working paper, 2001)Measurements from an array of current meter moorings along a section between Norway and Bear Island indicate that the seasonal mean of inflowing Atlantic Water extends further to the north during the summer than during ... -
Current patterns during pelagic stages determine interannual variability in length-at-age of juvenile Arcto-Norwegian cod
(ICES CM documents, Working paper, 2001) -
Factors influencing tag-recovery rates in the Norwegian spring-spawning herring tagging scheme
(ICES CM documents, Working paper, 2001) -
Estimating catch-at-age from market sampling data using a Bayesian hierarchical model
(ICES CM documents, Working paper, 2001) -
Dispersal and By-Catch Mortality in Grey, Halichoerus grypus, and Harbour, Phoca vitulina, Seals Tagged at the Norwegian coast
(ICES CM documents, Working paper, 2000)The results of the study presented here are submitted to a refereed journal for consideration. The review and printing process may not be completed at the time of the 2000 ICES Annual Science Conference and the subsequent ... -
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 ... -
Assessing the precision of the estimated age distribution of the commercial catch of Northeast Arctic cod
(ICES CM documents, Working paper, 2001)The assessment of Northeast Arctic cod is based on estimates of the commercial catch numbers at age. The age structure of the catch is estimated by sampling individuals from commercial fishing trips. Though it is commonly ... -
Harbour seal Phoca vitulina habitat use and interactions with fisheries as explored by a combined GIS and population energetics model
(ICES CM documents, Working paper, 2000) -
The Mean Sea Level Pressure (MSLP) Gradient across the Denmark Strait as Index for the Oceanographic Conditions in North Icelandic Waters
(ICES CM documents, Working paper, 2002)The oceanographic conditions in Icelandic waters are closely related to atmospheric forcing. In the present paper winter means of the atmospheric sea level pressure gradient across the Denmark Strait are correlated to a ... -
Evaluating the effectiveness of biological reference points in conserving reproductive potential
(ICES CM documents, Working paper, 2001) -
Reaction norm analysis of fisheries-induced adaptive change and the case of the Northeast Arctic cod
(ICES CM documents, Working paper, 2002)We present a probabilistic concept of reaction norms for age and size at maturation, and outline methods that can be used for their estimation in typical fisheries data. Such estimations are critical for calibrating size- ... -
The use of Medium-Term Forecasts in advice and management decisions for the stock of Norwegian spring spawning herring (Clupea harengus L.)
(ICES CM documents, Working paper, 2000)Medium-term simulations on the stock development of Norwegian spring-spawning herring (Clupea harengus L.) have been carried out since 1994 by the ICES «Atlanto-Scandian Herring and Capelin Working Group», in 1996 renamed ... -
The influence of fish behaviour on acoustic abundance estimates during the spawning season in Norwegian spring-spawning herring
(ICES CM documents, Working paper, 2001) -
Mortality and injuries of haddock (Melanogrammus aeglefinus) that are caught by pelagic longline
(ICES CM documents, Working paper, 2002)By-catches of haddock (Melanogrammus aeglefinus) below legal size (44 cm total length) in the seasonal pelagic longline fisheries for haddock off the coast of Finnmark, northern Norway, are often high. The small fish are ... -
Maturation characteristics in Norwegian spring-spawning herring before, during, and after a major population collapse
(ICES CM documents, Working paper, 2002)The immense Norwegian spring-spawning herring (Clupea harengus) population collapsed to the state of commercial extinction in the late 1960s, probably largely due to overfishing; the stock has fully recovered since the ... -
Application of Coded Wire Tagging Technology in Pacific Herring to Investigate Stock Structure and Migration
(ICES CM documents, Working paper, 2001)Tagging of Pacific herring in British Columbia has a long history dating to the mid-1930s but uncertainty in tag recovery locations and low tag return rates limited the utility of these studies. Currently, a larger and ... -
Modelling herring target strength pressure dependence in the frequency domain
(ICES CM documents, Working paper, 2001)Improved understanding of the acoustic scattering properties of the fish is needed when trying to remove potential bias is acoustic abundance estimates. The paper address the problem of systematic pressure or depth dependency ... -
Reaction norms for age and size at maturation: study of the long-term trend (1970-1998) for Georges Bank and Gulf of Maine Atlantic cod stocks
(ICES CM documents, Working paper, 2002)Average age and size at maturation have decreased in many commercially exploited fish stocks during the last few decades. This phenomenon could be either a direct phenotypic response to some environmental variation, or the ...
