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 ... -
Use of tag-recovery data to determine migration routes of Norwegian spring-spawning herring
(ICES CM documents, Working paper, 2001) -
Using acoustic surveys to improve the prediction of bottom trawl indices of abundance
(ICES CM documents, Working paper, 1991) -
Using artificial neural networks to combine acoustic and trawl data in the Barents and North Seas
(ICES CM documents, Working paper, 2004)Groundfish have a wide and variable distribution making the use of trawling alone a highly inadequate sampling method. Trawl data provide species identification and numbers over a very small area and habitat type while ... -
Using mark-recapture methods to estimate pup production of harp seals (Phoca groenlandica) in the Greenland Sea
(ICES CM documents, Working paper, 1992)During the period 1968-1991 16,917 harp seal pups have been tagged in the Greenland Sea. From 1976 until 1991, there have been 468 recoveries. 73 of these, mostly drowned in fishing gear or part of Inuit catches at Greenland, ... -
Vaccination against Vibrio salmoncida results from three laboratory trials
(ICES CM Documents;1987/F:24, Working paper, 1987)Atlantic salmon smolts (Salmo salar) were vaccinated with a bacterin made from formalin-killed Vibrio salmonicida. In laboratory trials, fish vaccinated once showed little or no protection after challenge. Fish vaccinated ... -
Vaccination of Arctic char (Salvelinus alpinus) against vibriosis
(ICES CM Documents;1988/F:13, Working paper, 1988)Arctic char of six different strains have been vaccinated against vibriosis and a relative protection (RPP) of 98% was demonstrated by waterborne challenge. This species is highly susceptible to vibriosis and the gross ... -
Validating three methods for making probability statements in fisheries forecasts.
(ICES CM documents, Working paper, 2000)We report on a test of three methods that have been used by ICES in making probability statements about fisheries forecasts to management agencies (XSA/WGMTERM, ICA/ICP, and a stochastic projection method that was first ... -
Validation and sensitivity study of a Sigma-coordinate ocean model using the Skagex dataset
(ICES CM Documents;1996/C:5, Working paper, 1996)Numerical ocean models are now being applied in numerous oceanographic studies. However, standards and procedures for evaluation of these models are far from established. In this paper the use of data from hydrographical ... -
Validation of a 3-D Biophysical Model using Nutrient Observations in the North Sea

Validation of three-dimensional hydrodynamic models in the Gulf of Finland based on a statistical analysis of a six-model ensemble
(ICES CM documents;2008/L:06, Working paper, 2008)Six three-dimensional hydrodynamic models were compared in their simulations of the hydrographic features of the Gulf of Finland in the Baltic Sea in the summer-autumn period of 1996. Validation was undertaken using more ... -
Variabilities in stomach contents of cod, collected by demersal and pelagic trawl in the southern part of the Barents Sea
(ICES CM Documents;1990/G:3, Working paper, 1990)Samples of Northeast Arctic cod stomachs were collected separately on demersal and pelagic stations at the same date in February 1986 and were analysed for length group 30-40cm. The results indicate that the mean value ... -

Variability of the drift patterns of spring spawned herring larvae and the transport of water along the Norwegian shelf
(ICES CM Documents;1995/Q:25, Working paper, 1995)Summary: A 3-dimensional baroclinic hydrodynamic model implemented for the North Sea, the Norwegian coast and part of the Norwegian and Barents Seas has been run for 18 years. This model has been used to study the Norwegian ... -
Variation in acoustically measured abundance from repeated surveys of herring
(ICES CM documents, Working paper, 1998)A large concentration of wintering herring was surveys continuously with acoustics over 37 hours in a fjord in Northern Norway. 16 surveys of the same area were conducted. Total abundance and statistics were computed for ... -
Variation in age at sexual maturity in rainbow trout

Variation in fish condition between Atlantic cod (Gadus morhua) stocks and implications for their management
(ICES CM documents, Working paper, 2000)A comparative analysis of the fish condition (Fulton’s K) of 11 cod stocks in the North Atlantic in relation to the temperature of their habitat and their reproductive potential is presented. It is shown that the cod ... -
