Killer whales (Orcinus orca L.) and saithe (Pollachius virens L.) trap herring (Clupea harengus L.) in shallow water by taking advantage of steep bottom topography
(ICES CM Documents;2002/N:20, Working paper, 2002)Whales and fish use a wide range of hunting tactics in order to catch their prey. Predatorprey interactions have been seen during the massive wintering of herring (Clupea harengus) in steep bottomed topography in Lofoten, ... -

Landscape dynamics and predator-prey interactions in marine environments
(ICES CM documents, Working paper, 2004)In several sub-arctic marine ecosystems of the North Atlantic capelin are the primary prey item for cod, and the trophic interaction between capelin and cod is a central energetic pathway. However, in the North Pacific ... -
The language of fishery management advice offered by ICES
(ICES CM documents, Working paper, 2003)Since the establishment of the Exclusive Economic Zones in the mid 1970s, several exploited fish stocks in the Northeast Atlantic have been managed by total allowable catch (TAC). The advice on annual levels of TAC, as ... -
Large scale release experiment of juvenile lobsters, Homarus gammarus, in Norway
(ICES CM Documents;1990/K:2, Working paper, 1990)A large scale spring release of juvenile lobsters, Homarus gammarus, was conducted at Kvitsøy, southwestern Norway in March 1990. The lobsters, 14,700 one and a half year old and 8,700 six months old, were tagged internally ... -

Length and age at maturity of Norwegian spring-spawning herring for the year-classes 1959 -61 and 1973 -78
(ICES CM Documents;1986/H:42, Working paper, 1986)The age and length at maturity is calculated for the six year-classes, 1973-78. The age at maturity is also calculated for the year-classes 1959-61. The two periods are caracterized by great differences in stock abundance ... -
Length and species dependent diurnal variation in catch rates in the Norwegian Barents Sea bottom trawl surveys
(ICES CM documents, Working paper, 1997)Diurnal variation in capture efficiency may add to the variability in swept area estimates (or indices) from bottom trawl surveys. In the present study the relationship between the day/night ratio of swept area estimates ... -
Length dependant corrections of survey estimates of cod and haddock in the Barents Sea
(ICES CM documents, Working paper, 1994)This paper describes an attempt to utilize new information on gear selectivity and fish target strength to improve time series of survey estimates. Swept area estimates and acoustic estimates of cod and haddock in the ... -
Length structure of deep-pelagic fishes sheds new light to their life histories
(ICES CM documents;2008/C:14, Working paper, 2008)Here we use a new technique to study life history variation in deep-pelagic fishes from a midocean ridge system. Shape of length distribution in a population is to a significant extent determined by the degree to which ... -
LENKA - A nation-wide analysis of the suitability of the Norwegian coast and watercourses for aquaculture. A coastal zone management program
(ICES CM Documents;1988/F:11, Working paper, 1988)A coastal zone management program called LENKA was started in 1987 and is to be terminated in 1989. The aim is to make an efficient and standardized tool for coastal zone planning, which, pertaining to law, is the ... -

Lidar TS measurements on Northeast Atlantic mackerel (Scomber scombrus)
(ICES CM documents, Working paper, 2003)A green linearly polarized laser and a digital video camera were used to find the average reflectivity and lidar target strength of live mackerel. The light reflected from the fish was compared to that reflected from a ... -
Life history and exploitation of the Norwegian spring spawning herring
(PINRO-IMR Symposium, Conference object, 1990)This paper is a review of the history and exploitation of the Norwegian spring spawning herring stock. In a virgin state the biomass of this stock may have ranged from 15 to 20 million tonnes and it was the most important ... -

The life with harmful algae in Norway - management
(ICES CM documents, Working paper, 1999)Harmful phytoplankton is a part of the natural, marine flora. The need for management and mitigation of their occurrence and effects has raised with the increased use and utilization of the coastal waters. Besides ... -
Limiting inter-annual variation in total allowable catch strategies. An application to ICES roundfish stocks
(ICES CM Documents;2003/X:7, Working paper, 2003)This study evaluated through simulation management strategy that stabilise catch levels by setting bounds on the inter-annual variability in Total Allowable Catches (TACs). An integrated modelling approach was used, which ... -
Linking tagging technology and molecular genetics to gain insight in the spatial dynamics of two stocks of cod in Northeast Atlantic waters
(ICES CM documents, Working paper, 2006)The Northeast Arctic cod (Gadus morhua L.: NEAC) is thought to be the most abundant cod stock in the North Atlantic, while the catches of the partially co-occurring Norwegian coastal cod (NCC) stocks have dramatically ...
