(ICES CM Documents;1985/H:38, Working paper, 1985)During the period 22 May to 17 July the spawning area of North Sea mackerel was investigated by research vessels from Scotland, the Netherlands, Denmark and Norway. Based on the 629 plankton samples and temperature ... -
The egg production and spawning stock size of the North Sea mackerel stock in 1990
(ICES CM Documents;1991/H:11, Working paper, 1991)During the period 12 March to 20 July 1990 the spawning area of the North Sea mackerel was investigated by research vessels from the Netherlands, Denmark and Norway. Based on the plankton samples and temperature observations ... -
The equivalent beam angle and its effective value when applying an integrator threshold
(ICES CM Documents;1987/B:35, Working paper, 1987)In a noise-limited echo integration system, a threshold is applied in order to avoid the contribution from noise. As the signal-to-noise ratio decreases with range, the effective observation volume for small targets is ... -
The health status of commercially exploited native flat oysters (Ostrea edulis) in Norway
(ICES CM Documents;1992/K:44, Working paper, 1992)The first systematic health survey of commercially exploited flat oysters (Ostrea edulis) has been carried out since 1989. The survey was performed on two important broodstocks in traditional oyster-production areas. No ... -

The importance of predator–prey overlap—predicting North Sea cod recovery with a multispecies assessment model Alexander
(ICES CM documents;2010/C:11, Working paper, 2010)The Ecosystem Approach to Fisheries (EAF), nowadays worldwide on political agendas, takes into account ecosystem knowledge, considers multiple external influences and looks at the broader impact of fisheries on the entire ... -
The influence of a stimulated transportation of newly fertilized Atlantic salmon eggs on mortality to the eyed stage
(ICES CM Documents;1985/F:29, Working paper, 1985)Transport of newly fertilized eggs has often resulted in severe mortality of the eggs during incubation to the eyed stage. To investigate the effect of transport on mortality, pooled eggs from several females were handled ... -
The Jutland Current: Nutrients and physical oceanographic conditions in late autumn 1989
(ICES CM Documents;1990/C:35, Working paper, 1990)Hydrography, currents, nutrients, water transparency, in situ chlorophyll fluorescence and primary production were studied during a cruise with R/V "G.O. Sars" to the west coast of Denmark, Skagerrak and Kattegat from ... -
The killing of the north-east Atlantic plankton feeders: Man the murderer or accessory to the crime?

The measurement error of marine survey catches: the bottom trawl case
(ICES CM Documents;2001/P:6, Working paper, 2001)We have formulated a model for analyzing the measurement error of marine survey abundance estimates using data from parallel surveys (trawl haul or acoustic measurement). The measurement error is defined as the component ... -
The migration of coastal cod (Gadus morhua L.) tagged in a fjord of western Norway
(ICES CM Documents;1988/G:5, Working paper, 1988)This study is part of a research program investigating the possibility of enhancing the production of coastal cod via a large scale release of pond produced fish in Masfjorden, a fjord of western Norway. An analysis of ... -
