An ecosystem modeling approach to predicting cod recruitment
(ICES CM documents, Working paper, 2006)Abstract The NORWECOM ocean model system implemented with the ROMS ocean circulation model has been run to simulate conditions over the last 25 years for the North Atlantic. Modelled time series of volume fluxes, primary ... -
Ecosystem responses to recent climate variability: comparison of four northern hemisphere regions

The effect of ambient temperature on the spawning migration of capelin
(PINRO-IMR Symposium, Conference object, 1987)The model presently in use for management of the Barents Sea capelin stock may be considerably improved by utilization of biological information from the spawning stock. The distributions of length and age for capelin ... -
Effect of attractant distribution on catch rate and size selection of Norway lobster caught by pots
(ICES CM Documents;1991/B:45, Working paper, 1991)In comparative fishing trials with Norway lobster (Nephrops norvegicus) pots, the attractant property of an aqueous extract of mackerel was tested against that of natural mackerel bait. The catch rate of the natural ... -
The effect of biological and physical factors on the survival of Arcto-Norwegian cod and the influence on recruitment variability
(PINRO-IMR Symposium, Conference object, 1987)Data from egg and larval field investigations h the Lofoten area are used together with long time series of data on temperature and zooplankton in Lofoten and abundance indices of Arcto-Norwegian cod. The importance ... -
Effect of different long-line baits (mackerel, squid) on catch rates and selectivity for tusk and ling
(ICES CM Documents;1983/B:31, Working paper, 1983) -
Effect of missing modes on calibration sphere target strengths
(ICES CM Documents;1996/B:37, Working paper, 1996)It has been suggested that modes of vibration of solid elastic spheres, such as those used in the calibration of echo sounder systems, can be affected by the manner of suspension. This hypothesis is investigated in the ... -
Effect of size-selective mortality on growth of coastal cod (Gadus morhua L.) illustrated by tagging data and an individual-based growth and mortality model
(ICES CM Documents;1996/G:48, Working paper, 1996)Since 1983 more than one million reared cod juveniles have been tagged and released in different areas along the Norwegian coast. The goal of the programme is to evaluate the ecological and economical potential in sea ... -
Effect of swimming on fish target strength
(ICES CM Documents;1985/B:29, Working paper, 1985)The influence of the swimming movement on fish target strength is investigated through a modelling exercise. In this, several gadoid specimens are represented as acoustic scatterers through their triangulated swimbladder ... -
Effect of the of temperature on development of embryos and hatching eggs of deep sea prawn (Pandalus borealis KRØYER)
(ICES CM Documents;1976/K:36, Working paper, 1976) -
Effect of turbulence and different types of fertilizers on phytoplankton and oyster larvae (Ostrea edulis) in mesocosms
(ICES CM Documents;1986/K:41, Working paper, 1986)Different types of inorganic fertilizers were added to five cubic metres plastic bags. Different turbulent regimes were established in the bags. The effects of these manipulations on nutrient salts, chlorophyll a, ... -
Effects of a geophysical survey on catching success in longline fishing
(ICES CM Documents;1991/B:40, Working paper, 1991)The effects on longline catches of a geophysical survey conducted during the winter fishery for cod (Gadus morhua) were studied. Spatial extent of the effects was investigated by comparing the catch rates of longlines ... -
The effects of a minimum landings size regulation in the fishery of Norwegian spring-spawning herring
(ICES CM Documents;1986/H:51, Working paper, 1986)Effects of minimum landing size (LC) in the fishery of Norwegian spring-spawning herring have been investigated. The herring is assumed to be a unit stock, in which the growth of immatures differs according to the ... -
Effects of climate and stocks interactions on the yield of north-east arctic cod. Results from multispecies model run
(ICES CM documents, Working paper, 2000)A conceptual climate dependent multispecies model for stock interactions and harvesting of herring, capelin and cod in the Norwegian Sea-Barents Sea region has been developed. The concept presupposes that good recruitment ... -
Effects of climate on marine ecosystem
(ICES CM Documents;2003/O:7, Working paper, 2003)The spawning areas of the Arcto-Norwegian cod are located along the coast of mid and northern Norway, particulary in the Lofoten where up to 70% of the spawning occurs from mid March to early May. The larvae are carried ... -
Effects of continuous flow rate on development and mortality of halibut yolk sac larvae
(ICES CM Documents;1990/F:41, Working paper, 1990)Halibut (Hippoglossus hippoglossus L.) yolk sac larvae were raised in incubators with different rates of continuous flow. Most larvae died between Days 10 and 29 after hatching. Rate of mortality increased with increasing ... -
Effects of different rearing environments on the mortality of Atlantic salmon broodstock and eggs
(ICES CM Documents;1984/F:26, Working paper, 1984)Atlantic salmon (Salmo salar) reared for three years in seawater were moved to brackish- and freshwater before they matured. A control group matured in seawater. The groups were given different feeding regimes the last ...
