The Drupa oil spill, investigation concerning oil, water and fish
(ICES CM Documents;1976/E:34, Working paper, 1976) -
Dynamics in frequency of skipped reproduction in Norwegian spring-spawning herring
(ICES CM documents, Working paper, 2004)A common presumption in fisheries science is that adult iteroparous fish, once matured, typically spawn in all consecutive years. Recent evidence suggests, however, that skipping of reproduction occurs more commonly than ... -
Dynamics of maturation in long-lived fish populations. II. Norwegian spring spawning herring
(ICES CM Documents;1993/H:20, Working paper, 1993) -
Dynamics of moving masses: Variability in packing density and shape among pelagic schools
(ICES CM Documents;1990/B:40, Working paper, 1990)The packing density and external shape of herring, saithe and sprat schools in the North Sea and along the Norwegian coast are measured acoustically. The packing density was inversely. related to the fish size, but species ... -
Dynamics of wintering Norwegian spring-spawning herring at the entrance to Tysfjorden, December 1996
(ICES CM Documents;1997/CC:16, Working paper, 1997)The entrance region to Tysfjorden was acoustically surveyed a total of eleven times during the December 1996 abundance survey of the spawning stock of Norwegian spring-spawning herring (Clupea harengus). The observations ... -
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
(ICES CM documents, Working paper, 2006) -
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 ... -
