Polyaromatic hydrocarbons (PAHs) in the Barents Sea sediment: Small changes over the recent 10 years
(IMR/PINRO Joint Report Series;5/2007, Conference object, 2007) -
Population genetic structure of grey seals (Halichoerus grypus) : Diversity, differentiation and prospects for genetic population assignment with special reference to Norwegian waters
(ICES CM documents;2007/L:25, Working paper, 2007)Population structure of grey seal breeding colonies in Norway (n=300), Northwest Russia (n=40) and Scotland (n=100) is currently being investigated based on Mt-DNA control region sequencing and fragment analysis (8 ... -
Population genetic structure of wrasses used as cleanerfish in Atlantic salmon farming in Norway
(ICES CM Documents;1993/G:30, Working paper, 1993)The increasing use of wrasses as cleaner fish in the salmon farming industry has created local fishery in many regions in Norway. In several cases, live fish have been transported between regions without knowledge of the ... -
Population genetic studies in Northeastern Atlantic minke whales
(ICES CM documents;2007/L:21, Working paper, 2007)Minke whales are the most abundance species of baleen whales in the North Atlantic. As part of current management of minke whales in Norwegian and adjacent waters, a DNA-register have been established. The register ensures ... -
Population structure of Ammodytes marinus in the Northeast Atlantic
(ICES CM Documents;1996/G:23, Working paper, 1996)Samples of the lesser sandeel species Ammodytes marinus Raitt were collected from Iceland, Denmark, Scotland, the Faeroe Islands and central and northern North Sea, and analysed for frequency distributions of genotypes ... -
Population structure of Sebastes mentella in the North-East Arctic
(ICES CM documents, Working paper, 1998) -
Position prediction of herring schools in purse-seine capture situations
(ICES CM Documents;1987/B:10, Working paper, 1987)Sonar observations of herring schools in the North Sea and along the Norwegian Coast reveal a rather constant swimming behaviour of individual schools in purse-seine capture situations. On the basis of this a method for ... -
Positive relationships between bottom trawl and acoustic data
(ICES CM documents, Working paper, 2004)Demersal fish stock biomass is usually estimated using commercial landings data, ‘tuned’ by various types of survey data, usually trawl. When collecting fish data by trawl it is only possible to take relatively small numbers ... -
Possibilities and limitations of extensive aquaculture of marine fish: evaluation of current results with Atlantic cod and further prospects
(ICES CM documents, Working paper, 1998) -
The potential importance of the paternal contribution to the ‘Stock Reproductive Potential’ of North-East Arctic cod (Gadus morhua)
(ICES CM documents, Working paper, 2005)Over the years there has been a growing interest in determining the real stock reproductive potential (SRP) as a means of understanding the dynamics of a fish population. For the purposes of assessment the spawning stock ... -
Potential sources of unaccounted mortality in the fishery for Norwegian spring spawning herring
(ICES CM documents, Working paper, 2002)The stock of Norwegian spring spawning herring (NSSH) is managed and fished by 5 different parties. These are the EU, Faroe Islands, Iceland, Norway and Russia. The most common gears are purse seine and pelagic trawl. The ... -
Pre-recruit studies of the North-East Arctic Greenland halibut stock
(PINRO-IMR Symposium, Conference object, 1995)Abundance indices of 0-group Greenland halibut (Reinhardtius hippoglossoides) from the international 0-group surveys in the Barents Sea showed a sudden decrease from 1987 to 1988 to a low level which has remained for the ... -
Precision in recruitment estimates and its implications on management of demersal fish stocks
(PINRO-IMR Symposium, Conference object, 1995)Errors in abundance indices of recruiting year-classes will affect stock predictions. The contribution of recruiting year-classes to the predictions of catch and spawning stock biomass for the stocks of Northeast Arctic ... -
Predation by Benguela hake (Merluccius polli) on commercially exploited shrimps (Parapenaeus longirostris and Aristeus varidens) in Angolan waters.
(ICES CM documents, Working paper, 1997) -
Predation by juvenile herring (Clupea harengus L.) on Barents Sea capelin (Mallotus villosus Muller) larvae
(PINRO-IMR Symposium, Conference object, 1995)In years with high abundance of juvenile Norwegian spring spawning herring in the Barents sea, the year-class strength of capelin has frequently been observed to be poor. It has therefore been suggested that predation ... -
Predation of oyster larvae by Aurelia aurita in a Norwegian oyster pond
(ICES CM Documents;1986/F:21, Working paper, 1986)In the norwegian oyster spatting ponds several factors may influence the spat production. During a basic, general study in a pond in 1983-84, Aurelia aurita was demonstrated to be a heavy predator on pelagic oyster ... -
Predation on fish larvae as a regulatory force illustrated in enclosure experiments with large groups of larvae
(ICES CM Documents;1983/L:39, Working paper, 1983) -
Predation on herring (Clupea harengus) eggs and young larvae.
(ICES CM Documents;1980/H:33, Working paper, 1980)The study presented here is part of a greater project dealing with recruitment studies of a local herring stock in Lindåspollene north of Bergen. Fish predators on herring spawn, mainly cod and haddock, were trapped ... -
Predation on the eggs of Norwegian spring-spawning herring at a spawning ground outside the westcoast of Norway in 1981
(ICES CM Documents;1985/H:55, Working paper, 1985)Predation on the eggs of demersal spawners has been reported several times, and findings of haddock feeding on capelin or herring eggs is a well known phenomenon. A spawning ground where spawning has been detected through ...
