Estimates of mackerel stock composition in different areas and reasons as indicated by a cestone parasite
(ICES CM documents, Working paper, 1983)Recently collected data support earlier indications of the value of the plerocercus of the trypanorhynch oestone Grillotia angeli as a biological tag for estimating the size of the Western stock component in populations ... -
Estimates of stock size of cod, haddock, redfish and Greenland halibut in the Barents Sea and the Svalbard area autumn 1988
(ICES CM documents, Working paper, 1989)Combined acoustic and bottom trawl survey for cod, haddock and redfish were carried out in autumn 1988 in the Svalbard area together with an acoustic survey in the Barents Sea. The abundance indicies of cod decreased from ... -
Estimates of stock size of Northeast Arctic cod and haddock from survey data 1986/1987
(ICES CM documents, Working paper, 1987)Combined acoustic and bottom trawl survey for cod and haddock were carried out in the Svalbard area in autumn 1986 and in the Barents Sea during the winter 1987. An acoustic survey for spwaning cod was carried out in March ... -
Estimates of stock size of northeast arctic cod and haddock, Sebastes mentella and Sebastes marinus from survey data, winter 1989
(ICES CM documents, Working paper, 1989)The combined acoustic and bottom trawl survey in the Barents Sea in winter has been carried out since 1981. The target species are cod and haddock, but in recent years the redfish species Sebastes marinus and Sebastes ... -
Estimating Abundance of Seals in a Drifting Environment: 2005: Pup Production of Harp Seals, Pagophilus groenlandicus, in the Northwest Atlantic
(ICES CM Documents;2005/R:06, Working paper, 2005)Photographic and visual aerial surveys to determine current pup production of northwest Atlantic harp seals were conducted off Newfoundland and Labrador (the “Front”), and in the Gulf of St. Lawrence during March 2004. ... -
Estimating and decomposing total uncertainty for survey-based abundance estimates of Norwegian spring-spawning herring
(ICES CM documents, Working paper, 2006)We demonstrate how the total uncertainty of the abundance estimate and abundanceat- age estimate of Norwegian spring-spawning herring are affected by uncertainty in the parameters of vessel avoidance, shadowing and depth ... -
Estimating initial stomach content using stochastic simulation
(ICES CM Documents;1994/G:16, Working paper, 1994)The stomach evacuation model now in use when quantifying the predation from cod on Barents Sea capelin assumes that the evacuation rate is dependent on the stomach fullness after the last meal, which is not known in the ... -
Estimating the maturity ogitive for Northeast Arctid cod by a modified assessment model
(PINRO-IMR Symposium, Conference object, 1984)The exploitation (1967-77) of the Northeast Arctic cod is splitted in 12 different fisheries. The mesh assessment model is modified in order to estimate the maturity ogive on the basis of the length and the age distributions ... -

Estimation of harp seal pup production in the Greenland Sea using spatial analysis on aerial survey data
(ICES CM documents, Working paper, 2005)From 14 March to 6 April 2002 aerial surveys were carried out in the Greenland Sea packice to assess the pup production of the Greenland Sea population of harp seals Pagophilus groenlandicus. One xed-wing twin-engined ... -
