From “where” and “when” to “what” and “why”: archival tags for monitoring “complex” behaviours in fish.
(ICES CM documents;2009/B:04, Working paper, 2009)Understanding the movements (“where” and “when”) and behaviour (“what” and, hopefully, “why”) of individuals and populations is key to answering fundamental questions in fish ecology. The use of archival tags in telemetry ... -
Full scale fishing trials for tusk (Brosme brosme) and cod (Gadus morhua) with a collapsible fish trap
(ICES CM Documents;1988/B:33, Working paper, 1988)A collapsible fish trap with low weight and low stacking volume has been developed and tested in full scale fishing operations. The catch rates of tusk were promising, while the catches of cod were too low and variable ... -
Full scale tests of improved longline gear
(ICES CM Documents;1985/B:45, Working paper, 1985)A new type of bottom set longline was tested in trials during the cod fishery off Finnmark November-December 1984. This gear differed from traditional longloine, by being rigged with swivel-mounted monofilament gangions ... -
Fullscale experiments with a new midwater 3-foil type and standard Waco and süberkrüb otterboards.
(ICES CM Documents;1979/B:25, Working paper, 1979)The experiments included comparative spread and depth measurements with equal rigging of a large blue-whiting trawl for 1500 HP vessel engine (6 to 8 m2 boards) and a 600 HP 4-pane1 combination trawl (4 to 4.5 m2 boards). ... -
Further experiments with radial escape section (RES) as fish-shrimp separator in trawl
(ICES CM Documents;1986/B:29, Working paper, 1986)A new approach to the bycatch problem when trawling for shrimp was initiated in Norway in 1984 utilizing the difference in swimming behaviour of fish and shrimp. A radial escape section (RES) in the aft belly of the ... -

(ICES CM Documents;1970/F:18, Working paper, 1970) -
Further results of Norwegian longline studies
(ICES CM Documents;1977/B:43, Working paper, 1977) -
Further Results of Tagging Experiments on Lobster (Homarus vulgaris) in Norway
(ICES CM Documents;1967/K:17, Working paper, 1967) -
Further results of the Norwegian mackerel investigations
(ICES CM Documents;1971/H:23, Working paper, 1971) -
Further studies on stock size fluctuations and rate of exploitation of the Norwegian spring spawning herring, 1950 - 1971
(ICES CM Documents;1973/H:19, Working paper, 1973) -
Gastric evacuation rate in mackerel (Scomber scombrus L.)
(ICES CM documents, Working paper, 1983)About 1500 mackerel, 25-45 cm in Length, were kept in a net for l0 days. In two experiments the fish were £ed frozen euphausiids -ad. libiturn, and the wet weight of the stomach content determined every second hour for ... -
Gelatinous zooplankton on the Mid-Atlantic Ridge, Distribution patterns of trawl-collected planktonic cnidarians
(ICES CM documents;2008/C:21, Working paper, 2008)The Mid-Atlantic Ridge (MAR) between 40˚N (Azores) and 63˚N (Iceland) is the largest topographic feature in the North Atlantic Ocean. However, the fauna and ecological significance of mid-ocean ridges has remained poorly ... -
A general system for logging information from instruments in the sea.
(ICES CM Documents;1978/B:23, Working paper, 1978)The paper describes a logging system which aims at integrating various forrns for primary data recording into a common standard that can be handled by the same reading and data processing equipment, Some illustrative ... -

(ICES CM documents;2009/Q:14, Working paper, 2009) -
Genetic comparison of salmon (Salmo salar L.) from the White Sea and the Atlantic ocean
(ICES CM Documents;1996/M:13, Working paper, 1996)Samples of salmon (Salmo salar) from River Kachkovka and R. Nilma in northem Russia were analysed by starch gel electrophoresis and compared to three Norwegian stocks, R. Neiden in northern Norway and R. Øyre and R. Hop ... -

Genetic studies on released and recaptured cod in a fjord system
(ICES CM Documents;1992/G:65, Working paper, 1992)The study reported here is part of a more extensive investigation on the effects of mass rearing and release of 0-group cod in fjords and coastal areas in Norway. Each year since 1987 pond produced cod have been liberated ... -

Geographic information systems (GIS) as tools for better integrated coastal zone planning and management (ICZP/M)
(ICES CM Documents;2000/O:3, Working paper, 2000)Geographic information systems (GIS) has practical applications in many areas, one of them being integrated coastal zone planning and management (ICZP/M). GIS can help combine several types of data from different sectors ... -
Geostatistical analysis of acoustic survey data on 0-group herring in a fjord
(ICES CM Documents;1992/D:10, Working paper, 1992)An essentially pure aggregation of 0-group herring in Altafjord in northern Norway was acoustically surveyed on each of the first three days of December 1991. Measurements were made at 38 kHz during each survey and at ...
