A comparison between three Atlantic salmon river stocks; using classical population genetics, differences in life history traits and performance in sea ranching
(ICES CM Documents;1997/P:13, Working paper, 1997)Characterisation of stocks is essential for fisheries and environmental management in order to conserve genetic diversity. However, classical populationgenetic methods frequently fail to document stock differences. In ... -
A genetic marker for artificially reared cod (Gadus morhua L.)
(ICES CM Documents;1987/F:22, Working paper, 1987)Artificially reared cod at the Aquaculture Station Austevoll on the west coast of Norway, were screened for genetic markers by using biopsies of white muscle, individual tags and enzyme genotype as determined by starch ... -
A study of genetic variation in northeast Atlantic harp seals (Pagophilus groenlandicus)
(ICES CM Documents;1991/N:5, Working paper, 1991)16 enzymes were examined for genetic studies of the harp seal population structure in the Northeast Atlantic. Muscle and liver samples were collected in the West Ice off Jan Mayen and in the Eastern Barents Sea in 1987, ... -
Artificial hatching substrate, effect on RNA / DNA ratio and protein retention during the yolk-sac period of Atlantic salmon (Salmo salar)
(ICES CM Documents;1985/F:31, Working paper, 1985)Genetical groups of Atlantic salmon (Salmo salar) were hatched in a Caiifonian hatching system with and without an astro-turf artificial hatching substrate, and were later transfered to separate feeding units. The ... -
Concepts used in the biochemical and serological identification of fish stocks
(ICES CM Documents;Sy:7, Working paper, 1969) -
Differentiation between "marinus" and "mentella" types of redfish by electrophoresis of hemoglobins
(ICES CM Documents;1971/F:26, Working paper, 1971) -
Distribution of multiple forms of lactate dehydrogenase, aspartate aminotransferase and serum esterase in herring samples from Norwegian waters
(ICES CM Documents;1969/16, Working paper, 1969) -
Eco-genetic models: a new framework for understanding fisheries-induced evolution
(ICES CM documents, Working paper, 2006) -
Esterase variation in herring studied by isoelectric focusing
(ICES CM Documents;1997/AA:1, Working paper, 1997)Few suitable genetic characteristics for studying herring population structure are available, and the main aim of the study reported here has been to reveal traits which display useful genetic variations for application ... -
Evaluation of genetic impact of aquaculture activities on native populations
(ICES CM documents;2007/L:06, Working paper, 2007)During the past 10 years, worldwide production of farmed fish has more than doubled, with farming activities now producing half of the fish directly consumed by humans. The potential genetic effects of aquaculture on natural ... -
Genetic comparison of salmon (Salmo salar L.) from the White Sea and the Atlantic ocean
(ICES CM Documents;1996/M:13, Working paper, 1996)Samples of salmon (Salmo salar) from River Kachkovka and R. Nilma in northem Russia were analysed by starch gel electrophoresis and compared to three Norwegian stocks, R. Neiden in northern Norway and R. Øyre and R. Hop ... -
Genetic diversity in salmon
(ICES CM Documents;1971/M:14, Working paper, 1971) -
Genetic studies on released and recaptured cod in a fjord system
(ICES CM Documents;1992/G:65, Working paper, 1992)The study reported here is part of a more extensive investigation on the effects of mass rearing and release of 0-group cod in fjords and coastal areas in Norway. Each year since 1987 pond produced cod have been liberated ... -
Individual based spatial models with evolved fish behaviour
(ICES CM Documents;1998/J:16, Working paper, 1998)Due to spatial heterogeneity, the survival and growth of fishes depend upon their habitat. For mobile pelagic fishes, it hence becomes important to analyse the factors responsible for spatial dynamics in order to understand ... -
Measurements of condition and growth of cod larvae reared in mesocosms: individual variability as a function of environmental condition or genetic inheritance
(ICES CM Documents;2001/V:8, Working paper, 2001)Size, dry weight and RNA/DNA measurements of 3876 cod larvae from 26 different families of recruit and repeat spawners reared in two mesocosms ( 2500m³ and 4400m³) under natural conditions were analysed. To be able to ... -
Mutual impact of wild and cultured Atlantic salmon in Norway
(ICES CM Documents;1988/Mini:5, Working paper, 1988)The development and current status of the fish farming industry, enhancernent and sea ranching of salmon in Norway are briefly described, and an account is given of the natural salmon river populations in different parts ... -
Occurence and structure of cysts in x-cell lesions of Atlantic cod (Gadus morhua L.)
(ICES CM Documents;1994/E:12, Working paper, 1994)Introduction: Despite numerous investigations the nature and origin of x -cells remain unknown. These ovoid, pale-staining cells with a large, round nucleus and prominent nucleolus are known to occur in the form of ... -
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 ... -
