Early development of Northeast Arctic greenland halibut (Reinhardtius hippoglossoides)
(ICES CM Documents;1998/O:27, Working paper, 1998)The early development of the Greenland halibut (Reinhardtius hippoglossoides) has never been described in detail. This study contains some preliminary notes on the egg development of the Northeast Arctic Greenland halibut ... -
The earth’s geomagnetic field and geolocation of fish: first results of a new approach
(ICES CM documents, Conference object, 2009) -
Eastern Scotian Shelf and Barents Sea intercomparison: climate fluctuations, human impact, and system resilience
(ICES CM documents;2010/S:10, Working paper, 2010) -
Eco-genetic models: a new framework for understanding fisheries-induced evolution
(ICES CM documents, Working paper, 2006) -
Ecological and Evolutionary Recovery of Exploited Fish Stocks

Ecological carrying capacity in shellfish culture Operational models of carrying capacity applied to a Norwegian fjord
(ICES CM documents;2008/H:09, Working paper, 2008)Estimation of production carrying capacity for shellfish culture has become a major focus in research, with operational models applied at culture sites worldwide. Fundamental to these efforts are an understanding of the ... -
Ecological Forecasting under Climate Change – the case of Baltic cod
(ICES CM documents;2009/C:01, Working paper, 2009)Ecosystems worldwide have already shown clear evidence of change in response to global warming. Since ecosystems provide vital goods and services, our ability to anticipate future changes is of great concern. In order to ... -
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
(ICES CM documents;2009:G:09, Working paper, 2009) -
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 ... -
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 ...
