An evaluation of recruitment indices for Northeast Arctic cod (Gadus morhua L.)
(ICES CM documents, Working paper, 1999)Indices of the abundance of Northeast Arctic cod (Gadus morhua L.) for various life stages were compared in order to determine the earliest stage at .which year-class strength is established. The indices considered are: ... -
An evaluation of the methodology for prediction of capelin biomass
(IMR/PINRO Joint Report Series, Conference object, 2005)The one-year prediction of capelin made as part of the assessment after the annual joint acoustic capelin survey during the autumn, is evaluated. Such predictions were made for the period from 1981 till present, and compared ... -

Evolution of growth in Gulf of St Lawrence cod?
(Journal article; Peer reviewed, 2008-06-22)Fishing is often size selective such that the likelihood of capture increases with body size. It has therefore been postulated that fishing could favour evolution of slower growth because smaller size would reduce exposure ... -
Evolutionary principles and their practical application
(Journal article; Peer reviewed, 2011-02-17)Evolutionary principles are now routinely incorporated into medicine and agriculture. Examples include the design of treatments that slow the evolution of resistance by weeds, pests, and pathogens, and the design of breeding ... -

Exploitation as a driving force of life history evolution: methods and empirical analyses
(ICES CM documents, Working paper, 2004)Today, fishing is the dominant source of mortality in most commercially exploited fish stocks. Life-history theory predicts that, under most circumstances, increased mortality at potential ages and sizes at maturation ... -
Extensive gas bubble release in Norwegian spring spawning herring (Clupea harengus) during predator avoidance
(ICES CM Documents;1998/J:20, Working paper, 1998)Events of extensive gas bubble releases in overwintering Norwegian spring spawning herring (Clupea harengus) were repeatedly observed acoustically and visually in Vestfjorden, northem Norway, during attacks from killer ... -
Factors affecting the vertical distribution of eggs [HELP 34]
(help;1990 nr. 34, Research report, 1990)The spatia1 distribution of eggs and larvae is a function of the properties of the ambient water, i.e. the density, current and turbulent diffusion, and of the physical properties of the eggs, i.e. the buoyancy and ... -
Factors affecting year-to-year and within river variability of one-sea-winter Atlantic salmon in Norwegian rivers
(ICES CM documents;2009/E:14, Working paper, 2009)Many Atlantic salmon, Salmo salar, populations are decreasing throughout its distributional range due to several factors acting in concert. A number of studies have documented the influence of freshwater and ocean ... -
Factors determining the year-class strength of Norwegian spring spawning herring
(PINRO-IMR Symposium, Conference object, 1995)More than 30 years of Russian and Norwegian data on spring-spawning herring larvae along the coast of Norway has been investigated and analyzed together with different environmental parameters and spawning stock size. ...
