DEEPFISHMAN: Management And Monitoring Of Deep-sea Fisheries And Stocks
(ICES CM documents;2009/N:22, Working paper, 2009)Deepwater fisheries pose particular difficulties for management. Target species are difficult to assess with adequate levels of certainty, they are slow growing and generally vulnerable to overfishing and many of these ... -
Deepwater flowthrough as a temperature stabilizer in rearing of halibut (Hippoglossus hippoglossus) fry
(ICES CM Documents;1987/F:16, Working paper, 1987)Through the period of yolk sac absorption, halibut larvae were kept in plastic bags in plastic basins with flowthrough of deepwater. When maintaining sufficient flowthrough, in this period the temperature in the bags ... -
Demersal fish on the continental slope off Norway
(ICES CM documents;1975/F:29, Working paper, 1975)Investigations on distribution and abundance of demersal fish in 400-1000 m depth were carried out in three selected areas off Norway in July-August 1974. Based on catches in 48 hauls by bottom trawl and 3 long-line settings ... -
Density-Dependent Growth in Saithe
(ICES CM Documents;1966/G:2, Working paper, 1966) -
The development and mortality of mackerel eggs (Scomber scombrus L.) in different temperatures
(CES CM Documents;1977/L:19, Working paper, 1977) -
The diet and consumption of mackerel in the North Sea (a preliminary report)
(ICES CM documents, Working paper, 1983)The contents of 3674 mackerel stomacks sampled during 1981 and 1982 are analysed and presented. The samples were taken by five countries at 270 different stations as a part of The International Stomach Sampling Programme ... -
Diet and food availability for Northeast Atlantic minke whales Balaenoptera acutorostrata
(ICES CM Documents;1995/N:19, Working paper, 1995)Ecological studies of the Northeast Atlantic minke whale (Balaenoptera acutorostra) were carried out during spring (mainly April-May), summer (June-July) and autumn (AugustSeptember) in 1993 and 1994. Four small-type ... -
Diet of harp seals (Phoca groenlandica) feeding between the breeding and moulting seasons in the southern Barents and White Seas
(ICES CM Documents;1993/N:8, Working paper, 1993)The harp seal Phoca groenlandica is the most abundant seal species in the Barents Sea. In order to evaluate the ecological importance of the species, diet studies have recently been carried out at various times of the ... -
The diet of North-East Arctic cod 1984-1994
(Working paper, 1995) -
Diet of polar cod, Boreogadus saida, in the Barents Sea related to fish size and geographical distribution
(ICES CM Documents;1990/G:48, Working paper, 1990)Polar cod stomachs collected during autumn of 1986-1988 in the Barents Sea were analysed. The results indicated that polar cod is an opportunistic feeder, and that the observed changes in feeding pattern from one region ... -
Diet of the harbour seal, Phoca vitulina, in the Hvaler area in 1990 and 1991, compared to the abundance of fish in the area
(ICES CM Documents;1992/N:19, Working paper, 1992)The harbour seal, Phoca vitulina, occurs in small groups along the entire coast of Norway. It is thought to interact with the commercial fisheries, both as predator and as final host for parasitic nematodes infecting ... -
Diet overlap between North-East Arctic cod and haddock in the southern part of the Barents Sea in 1984-1986
(ICES CM documents, Working paper, 1987)The diet composition of North-East Arctic cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) are examined from stomach content data. Fish were collected in the southern part of the Barents Sea from 1984 to 1986. A ... -
Differences between near bottom biomass spatial structure observed in the Irish Sea, the North Sea and the Barents Sea in recent years
(ICES CM documents, Working paper, 2003)Based on acoustic data and trawl catches collected during bottom trawl surveys, we compare the spatial structure of the biomass available in the first meters above the bottom in three different regions, the Barents Sea ... -
Differences in swimbladder volume between Baltic and Norwegian spring spawning herring: possible consequences for mean target strength
(ICES CM documents;2007/H:03, Working paper, 2007)Volume and shape of the swimbladder of Baltic and Norwegian spring spawning herring were measured, together with individual herring fat content. Swimbladder size was found to differ significantly between the two herring ... -
