Hindrer Nordhordlandsbroen smoltens utvandring?
(Havforskningsnytt, Working paper, 2007)Den dramatiske nedgangen av laksebestanden i Vosso har brakt flere institusjoner sammen for å undersøke betydningen av menneskeskapte forhold for denne utviklingen. De siste årene har søkelyset i hovedsak vært rettet mot ... -
Holistic evaluation of management policies: What are the consequences of modified gear use on Georges Bank?
(ICES CM documents;2009/ O:26, Working paper, 2009)Georges Bank haddock is a recently recovered fish stock in the New England groundfish fishery. Due to federal constraints under the Magnuson-Steven Act, however, this stock cannot be optimally exploited due to the bycatch ... -

How and why acoustic detectability and catchability of herring change with individual motivation and physiological state in a variable environment: a multi-scale study on a local herring population in southwestern Norway
(ICES CM documents, Working paper, 2006)The understanding of distribution and aggregation in herring (Clupea harengus) can be enhanced by integrated multi-scale studies in small ecosystems. Hydro-acoustics, underwater cameras, herring and predator gillnet samples ... -
How can a potential oil pollution affect the recruitment to fish stocks?
(ICES CM Documents;1989/Mini:5, Working paper, 1989)Eggs, larvae and the larvae's first search for food are the most critical stages in a fish life, both to threats from natural causes and pollution. Based on experimental studies of several species of fish eggs, larvae ... -
How does fishing alter marine populations’ and ecosystems’ sensitivity to climate? – An introduction
(ICES CM documents;2009 /F:01, Working paper, 2009)The effects of climate and fishing on marine populations and ecosystems have conventionally been considered separately and it has often been suggested that they should be disentangled from each other. However, exploitation ... -
How does stochasticity affect evolutionary regime shifts in age and size at maturation?
(ICES CM documents, Working paper, 2006)Fish in many exploited stocks grow faster and mature earlier at either larger or smaller sizes in comparison to pre-exploitation periods. These changes can be driven by both genetic and phenotypic responses. We have shown ... -
How many trawl hauls, and how many fish from each haul are needed to obtain a given precision in the age structure estimate for Norwegian spring spawning herring? A bootstrap approach
(ICES CM documents, Working paper, 2006)The Norwegian spring spawning herring is assessed each year from acoustic surveys. The age structure in the stock is estimated from trawl samples. Typically, about 10 trawl samples are taken per survey, and 100 fish from ... -
How to correct fish density estimates for extinction
(ICES CM Documents;1990/B:24, Working paper, 1990)There have been many experimental studies on acoustic shadowing, but once the effect is quantified, how is the compensation to be effected? This work shows how, through postprocessing of stored time series, containing ... -
How variable is the fecundity within and between cod stocks?
(ICES CM documents, Working paper, 2005)Stock reproductive potential is determined by the number of fish at age, sex ratio, proportion of mature female at age and fecundity. Fecundity data, which are fundamental in estimating egg production are not collected ... -
Hull mounted, protruding transducer for improving echo integration in bad weather
(ICES CM documents, Working paper, 1990)A 38 kHz split beam survey transducer has been mounted on the tip of a 4 m vertical protrusile stabilizing keel of the United States NOAA fishery research vessel R/V Miller Freeman. Air blocking problems, generally ... -
