Extent and ecological importance of escape through spawning in sea-cages for Atlantic cod
(Journal article; Peer reviewed, 2012-11-14)The culture of certain fish species to sizes at which they can reproduce has led to the escape of fertilised eggs or ‘escape through spawning’. To investigate the extent and ecological importance of spawning in sea-cages ... -
External peer review of survey serier: Lessons From the Rügen Herring Larvae Survey
(ICES CM documents;2007/P:10, Working paper, 2007)ICES coordinated surveys are, on a non-regular basis, reviewed by parent expert groups. A potential problem is that these are often conducted by evaluators being themselves involved in the surveys, thus lacking ... -
Extinction cross section of herring: New measurements and speculation
(ICES CM Documents;1994/(B+D+G+H):2, Working paper, 1994)Acoustic abundance estimation of dense, vertically extended aggregations of fish requires knowledge of the extinction cross section. An established method based on a comparison of the area backscattering coefficients ... -
Extreme male-skewed sex ratios on spaning grounds for Atlantic cod Gadus morhua with typical coastal cod signatures of the Pan I (pantophysin) locus
(Journal article; Peer reviewed, 2015-06-11)Large offshore and small inshore populations of Atlantic cod Gadus morhua L. display differences in migratory patterns and settling regimes, but little is known about possible differences in spawning behaviour. Cod presumably ... -

Factors affecting the distribution of wrasses in a fjord system: analysis by generalised linear models
(ICES CM Documents;2000/N:31, Working paper, 2000)Background: Generalised linear models (GLMs, see McCullagh & Nelder 1989) form a modern, flexible and unified approach to statistical modelling. GLMs are of particular value to the analysis of data from ecological surveys, ... -
Factors affecting the parr-smolt transformation in Atlantic salmon
(ICES CM Documents;1979/M:2, Working paper, 1979)Factors affecting the parr-smolt transformation in Atlantic salmon (Salmo salar) are reviewed. The factors discussed are growth rate, temperature, photoperiod, salinity, food quality and quantity and hormones. Significance ... -
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. ... -
Factors influencing risk assessments of brominated flame-retardants; evidence based on seafood from the North East Atlantic Ocean
(Journal article; Peer reviewed, 2018)Brominated flame-retardants (BFRs) such as polybrominated diphenyl ethers (PBDE) and hexabromocyclododecane (HBCD) are considered hazardous to human health. Due to their persistence, they are still present in the environment ... -

Factors influencing the Size of the Year Classes in the Arcto-Norwegian Tribe of Cod
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1957)1. The quantitative occurrence of eggs and larvae of the Arcto-Norwegian cod in the coastal and bank areas of northern Norway during the years 1948-1956 has been studied. 2. There is no correlation between the abundance ... -
Factors influencing year-class strength of Norwegian spring spawning herring (Clupea harengus Linné)
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1970)1. Variation in year-class strength of Norwegian spring spawning herring is analysed in relation to the structure and the size of the spawning stock, the location and the time of spawning and environmental conditions during ... -
Faggrunnlag stillehavsøsters (Crassostrea gigas)
(Rapport fra Havforskningen;Nr. 32 - 2014, Working paper, 2014-12-16)Mapping and surveillance of the invasive species pacific oyster are important elements to be able to choose the right management decisions. Collecting of pacific oysters along the coast will be very expensive and can ... -
