Distribution and growth of capelin in the Barents Sea in relation to water temperature in the period 1974 to 1983
(ICES CM Documents;1984/GEN:16, Working paper, 1984)The variation in the distribution of the different age-groups of capelin in the Barents Sea were studied in relation to temperature variation in the period 1974 to 1983. In addition, growth of the capelin were compared ... -
The distribution of cod-haddock in the Central and South-Eastern Barents Sea, September - October 1958
(ICES CM Documents;1959/44, Working paper, 1959) -
Distribution of escaped farmed salmon and rainbow trout in the sea and possible effects of salmon lice on wild stocks
(ICES CM Documents;2002/T:8, Working paper, 2002)The aims and first results of a recently started project are presented. The geographical and seasonal distribution of the catch and catch per unit effort of escaped farmed salmon and rainbow trout are studied in an area ... -
Distribution of herring (Clupea harengus) and zooplankton in the Norwegian Sea, as determined from generalised additive models
(ICES CM documents, Working paper, 2005)We analyse the variability in the distribution and feeding of the Norwegian spring-spawning herring in the period from 1995 to 2004, using survey data collected throughout the Norwegian Sea each year in May - June. The ... -
Distribution of multiple forms of lactate dehydrogenase, aspartate aminotransferase and serum esterase in herring samples from Norwegian waters
(ICES CM Documents;1969/16, Working paper, 1969) -
Distribution, drift and condition of herring larvae off western Norway in 1985
(ICES CM Documents;1986/H:39, Working paper, 1986)The recruitment to the Norwegian spring-spawning herring have during the last twenty years been on a very low level. However, the size of the spawning stock has increased in recent years and in 1983 a rich year class ... -
Distribution, drift and condition of herring larvae off western Norway in 1987
(ICES CM Documents;1988/H:14, Working paper, 1988)Introduction: After 1959 the Norwegian spring-spawning herring have been spawning along the western coast of Norway north of 62° N. During the sixties the stock was reduced to a minimum. In the recent years there has ... -
Diving observations on Barents Sea capelin at its spawning grounds off the coast of northern Norway
(ICES CM Documents;1971/H:25, Working paper, 1971) -
Do capelin larvae deposit daily increments in their otoliths?
(ICES CM documents, Working paper, 2004)Analysis of increment formation in larval fish otoliths has provided valuable information about growth, transport and mortality processes of larvae in wild stocks, but the technique has not been widely used on capelin ... -
Do two-year-old Arcto-Norwegian cod remain in the area where they settled?
(ICES CM documents, Working paper, 2001) -
Dramatic changes in spawning stock age-structure of Barents Sea cod
(ICES CM documents, Working paper, 2004)Atlantic Cod (Gadus morhua) is one of the commercially most important fish species in the North Atlantic and plays a central role in several ecosystems. Fishing pressure has been heavy over a prolonged period and the ... -
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) -
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 ... -

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 ... -
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 ... -
