The distribution of cod larvae and prey organism in the Lofoten area related to critical prey concentration
(PINRO-IMR Symposium, Conference object, 1984)The distribution of cod larvae and their main prey organisms in the first feeding areas off the Lofoten islands have been studied in sheltered and exposed areas in relation to feeding conditions. These findings are discussed ... -
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 deep sea shrimp (Pandalus borealis Krøyer) in relation to temperature in the Barents Sea
(PINRO-IMR Symposium, Conference object, 1987)In the years 1980 to 1985 stratided raildom bottom trawl surveys were carried out on the shrimp fields in the Svalbard and Barents Sea regions. The objeetives of the cruises were to study the structure of the shrimp stock ... -
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 accurate stock estimates increase harvest and reduce variability in fisheries yields?
(Journal article; Peer reviewed, 2011-03-22)Fisheries managers normally make decisions based on stock abundance estimates subject to process, observation, and model uncertainties. Considerable effort is invested in gathering information about stock size to decrease ... -
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 eggs collected in egg surveys accurately reflect adult fecundities?
(Conference object, 2014) -
Do two-year-old Arcto-Norwegian cod remain in the area where they settled?
(ICES CM documents, Working paper, 2001) -
Does Presence of a Mid-Ocean Ridge Enhance Biomass and Biodiversity?
(Journal article; Peer reviewed, 2013-05-02)In contrast to generally sparse biological communities in open-ocean settings, seamounts and ridges are perceived as areas of elevated productivity and biodiversity capable of supporting commercial fisheries. We investigated ... -
Does size matter? A bioeconomic perspective on optimal harvesting when price is size-dependent
(Journal article; Peer reviewed, 2011-09-09)Body size is a key parameter influencing demographic characteristics of fish populations as well as market value of landed catch. Yet in bioeconomic modelling, body size is often an overlooked biological and economic ... -

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 ...
