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 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 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 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 ... -

The distribution and abundance of harbour porpoises and other small cetaceans in the North Sea and adjacent waters
(ICES CM Documents;1995/N:10, Working paper, 1995)To provide accurate and precise estimates of abundance for harbour porpoises and other small cetaceans throughout the North Sea and adjacent waters, an intensive shipboard and aerial sightings survey was conducted in ... -

The ecosystem approach to fisheries – science driven or issue driven?
(ICES CM documents;2007/R:08, Working paper, 2007)The ecosystem approach to fisheries (EAF) represents a multi-objective aiming at 1) broadening the management perspectives from single species to including ecosystems considerations, 2) maintaining a precautionary approach ... -
The effect of a short time exposure to different temperature and salinity regimes on survival of maturing Atlantic salmon and eyed eggs, and changes in blood and seminal plasma during the spawning period
(ICES CM Documents;1986/F:25, Working paper, 1986)Maturing Atlantic salmon, transferred from brackish water two weeks prespawning, were held under four different temperature and salinity regimes through their spawning period. Values of blood glucose and haematocrit ... -
The effect of ambient salinity on the buoyancy of eggs from the Atlantic halibut (Hippoglossus hippoglossus)
(ICES CM Documents;1986/F:52, Working paper, 1986)The effect of ambient salinity on buoyancy and the formation of perivitelline fluid in eggs from the Atlantic halibut Hippoglossus hippoglossus have been investigated. The results clearly demonstrate that the water ... -

The effect of different photoperiods on growth and smoltification in Atlantic salmon (Salmo salar)
(ICES CM Documents;1985/F:32, Working paper, 1985)Photoperiod has been implicated as an effective mediator of growth and smelting in Atlantic salmon (Salmo salar). To investigate this 0+ parr of Atlantic salmon were treated with three different photoperiods: 24Light:0Dark; ... -
The effect of different sweep lengths on length composition of bottom sampling trawl catches
(ICES CM Documents;1987/B:16, Working paper, 1987)Abundance estimates of North-east Arctic cod and haddock are given annually on the basis of combined bottom trawl and acoustic surveys. Both survey methods use data from bottom trawl catches in the calculations. The ...
