A program for estimation of number and survival of a population, given a series of tag release/recapture data.
(ICES CM Documents;1982/G:7, Working paper, 1982)A computer program for convenient storage of tag release/recapture data is given. The program provides a facility to combine yearclasses if release/recapture are split into yearclasses. One estimate of number and three ... -
A quasi-synoptic survey of the European continental shelf edge during the SEFOS project
(ICES CM Documents;1995/C:10, Working paper, 1995)Quasi-synoptic surveys of the European continental shelf edge have been conducted since the spring of 1994 by participants in the Shelf Edge Fisheries Oceanography Study (SEFOS). The purpose of the surveys is primarily ... -
A quest for management objectives – case study on the Barents Sea Capelin
(ICES CM documents;2008/O:08, Working paper, 2008)The Barents Sea capelin is a short lived arctic pelagic species and a shared Norwegian-Russian stock. Although the management objectives for Barents Sea capelin have not been explicitly stated, the management authorities ... -
A Report on an Intercomparison Study of the Determination of Chlorinated Biphenyl (PCB) Isomers in Fish Oil
(ICES CM Documents;1981/E:49, Working paper, 1981)Five laboratories, employing capillary column gas chromatography, determined the levels of many chlorinated biphenyl isomers (PCB isomers) in Aroclor 1254 and in herring oil and the same oil spiked with Aroclor 1254. This ... -

A review of the distribution, migrations, food, reproduction, exploitation and present abundance of humpback whales (Megatera novaeangliae) in the northeast Atlantic
(ICES CM Documents;1990/N:10, Working paper, 1990)Most available knowledge about northeast Atlantic humpback whales (Megaptera novaeangliae) is based on information and experience gained during the pioneer period of modern whaling in Norwegian waters in 1868-1904 when ... -
A review of the process leading to the establishment of limit and precautionary reference points for the stock of Norwegian spring spawning herring
(ICES CM Documents;2000/X:8, Working paper, 2000)The Coastal State Regional Management Organisation agreed in October 1999 on a on a long time strategy for Norwegian spring spawning herring. Limit and precautionary reference points are fundamental parts of this long ... -
A set of Single Nucleotide Polymorphism (SNP) loci for generic distinction between Norwegian farm and wild Atlantic salmon (Salmo salar L.).
(ICES CM documents;2009/Q:01, Working paper, 2009)Atlantic salmon breeding programs were first established in Norway in the late 1960´s. Since then, production of farm salmon has steadily increased, and represents the economically most important aquaculture industry in ... -
A shift in a hake (Merluccius merluccius) population of the NW Mediterranean induced by a combined effect of climate and fishery harvesting
(ICES CM documents;2009/F:04, Working paper, 2009)Climate and fisheries are often interacting with each other and producing complex synergic effects on the population dynamics of marine species. The drastic change in the climatic conditions in the North Atlantic (NA) ... -

A stationary acoustic system for monitoring undisturbed and vessel affected fish behaviour
(ICES CM Documents;1996/B:12, Working paper, 1996)Thorough knowledge of the dynamics of natural fish behaviour and distribution within a survey and among surveys is fundamental for reliability of time series of abundance indices. Further, vessel/trawl affected avoidance ... -
