Food and feeding of young herring larvae of Norwegian spring spawners
(ICES CM Documents;1976/H:36, Working paper, 1976)The gut contents of young herring larvae sampled each hour from 4 to 9 April 1967 around a floating drogue at three depth intervals were examined to study their feeding. Copepod eggs constituated more than 90% of the ... -

Formation of heavy bottom water in the Barents Sea
(ICES CM Documents;1984/C:17, Working paper, 1984)Formation of heavy bottom water through rejection of brine during ide freezing is a regular phenomenon in the Barents Sea, particular on the Novaya Zemlya shelf, but also observed in other shallow localities of the ... -
Formation of nutrient rich bottom water in the eastern parth of the Barents Sea
(ICES CM Documents;1997/R:1, Working paper, 1997)During yearly routine observations of hydrography, nutrients and plankton in the Barents Sea we have observed a distinct anomaly in the distribution of the nutrients silicate and nitrate in near bottom water in an area ... -

The Fragility of Precautionary Reference Points
(ICES CM documents, Working paper, 2003)A basic idea in fisheries management is that a fishery should be managed so that there is sufficient spawning stock biomass left to reproduce after the following year’s fishing. An essential task for the scientists has ... -
A Framework for Communicating Qualities of Indicators
(ICES CM documents, Working paper, 2003)There is a growing focus on ecosystem-based indicators and what qualities they need to satisfy. However, the qualities and the characteristics of the already existing indicators vary substantially. Due to both scientific ... -
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 ... -

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 ...
