Testing of a new hook design (E-Z-Baiter) through comparative longline fishing trials
(ICES CM Documents;1986/B:25, Working paper, 1986) -
Testing of a new hook design in the longline fishery for tusk (Brosme brosme) and ling (Molva molva)
(ICES CM Documents;1987/B:20, Working paper, 1987)The EZ-Baiter Circle hook which is a hybrid design between the classical J- and Circle hook shapes, is developed to provide a more effective hook for use in mechanized longline systems. In comparative fishing trials, ... -
Testing various geostatistical models to combine bottom trawl catches and acoustic data
(ICES CM Documents;2004/R:28, Working paper, 2004)The aim of the CATEFA project is to combine information on demersal fish stock abundance from acoustic and bottom trawl surveys. While acoustic data are collected continuously while the research ship is underway, it is ... -
The activity of alevins of Atlantic salmon and rainbow trout, incubated on different substrates
(ICES CM Documents;1986/F:24, Working paper, 1986)Atlantic salmon (Salmo salar) and rainbow trout (S. gairdneri) eggs were incubated in plexi-glass aquariums. After hatching, alevins were kept in darkness, two groups of each species without substrate, two groups in ... -
The Barents Sea capelin 1983 -1988
(ICES CM Documents;1988/H:52, Working paper, 1988) -
The basic driving force: Oceanography
(ICES CM Documents;1988/C:30, Working paper, 1988)As early as the beginning of this century it was shown that variations in physical conditions have great influence on the biological conditions of various fish species. During the period 1930-1970, the magnitudes of ... -
The Benguela Niño 1995 observed in Angolan waters
(ICES CM Documents;1995/C:12, Working paper, 1995)During the cruise by R/V ''Dr. Fridtjof Nansen" in February-March 1995, we observed that the upper ocean layers were very warm and brackish. Comparing with a similar cruise performed in 1994, the water temperature was ... -
The bioeconomic consequences of fisheries ]induced adaptive changes
(ICES CM documents;2010/M:02, Working paper, 2010) -
The buoyancy of sprat (Sprattus sprattus) eggs and larvae in the Skagerrak area
(ICES CM Documents;1985/L:6, Working paper, 1985)Buoyancy of sprat eggs and larvae was determined with a linear density gradient. There were four experimental groups of eggs, three caught at sea and one from spawning in the laboratory. The neutral buoyancy of the sprat ... -
The capelin fishery 1972 -1988
(ICES CM Documents;1988/H:55, Working paper, 1988) -
The challenge of the herring in the Norwegian Sea: making optimal collective spatial decision
(ICES CM Documents;1996/H:15, Working paper, 1996)Herring are long-lived multiple spawners exhibiting strong variation in reproductive and recruitment success between years. They tend to adopt low-risk, preferred-conservative strategies; for example, shifts to alternative ... -
The choice of TAC when faced with multiple objectives
(ICES CM Documents;1996/P:15, Working paper, 1996)The total allowable catch is a key instrument in fishery management, and advice on its level used to be based purely on biology. In 1991, ACFM stated that its objective was to provide the advice necessary to maintain ... -
The Chrysochromulina polylepis bloom in the Skagerrak and the Kattegat in May - June 1988: Environmental conditions, possible causes and effects

The CoML pilot project MAR-ECO: Goals, status, and significance for ICES
(ICES CM Documents;2002/L:10, Working paper, 2002)The Mid-Atlantic ridge and adjacent waters are targeted in an international ecosystem study under the Census of Marine Life programme. This pilot project shall gather new knowledge on biodiversity, distribution patterns, ... -
The consumption rate of northeast Arctic cod - A comparison of gastric evacuation models
(ICES CM Documents;1990/G:22, Working paper, 1990)The consumption rates in fish are important but also often weak points in multispecies models. In the Barents Sea multispecies model (MULTSPEC), as in many other models, quantitative stomach content data are combined ... -
The daily feeding dynamics in various lenght groups of the Barents Sea capelin during the feeding period
(ICES CM Documents;1991/H:16, Working paper, 1991)A total of 700 capelin stomachs collected during the feeding period in August 1989 by 24-h fishery were analyzed for each 3-cm length groups. The number of prey categories consumed by the Barents sea capelin showed a ... -
The detection of larval fish food particles by an in situ particle counter, and monitoring of the particle density and distribution in first feeding areas.

The development of a new gillnet fishery for anglerfish (Lophius piscatorius) in Norwegian waters
(ICES CM Documents;1995/G:12, Working paper, 1995)In autumn 1992 a direct gillnet fishery for anglerfish (Lophius piscatorius) started on the continental shelf off the northwestern coast of Norway. The anglerfish had previously only been taken as bycatch in trawls and ... -
