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 ogive for northeast- arctic cod by a modified mesh assessment model
(ICES CM Documents;1983/G:33, Working paper, 1983) -
Estimation of unreported catch in a commercial trawl fishery
(ICES CM Documents;1991/D:12, Working paper, 1991)The Institute of Marine Research (IMR), Bergen, has carried out combined bottom trawl and acoustic surveys for cod in the Barents Sea since 1981. Commercial statistics are collected routinely for this area through the ... -
Evaluation of the North-East Arctic saithe (Pollachius virens) acoustic survey
(ICES CM Documents;1997/Y:20, Working paper, 1997)Since 1985 an acoustic survey specially designed for saithe has annually been conducted in October-November by the Institute of Marine Research (IMR) on the Norwegian near coastal banks. Since 1992 the survey has covered ... -
Evaluation of the Norwegian shrimp surveys conducted in the Barents Sea and the Svalbard area 1980- 1997
(ICES CM Documents;1997/Y:7, Working paper, 1997)Trawl surveys for shrimp (Pandalus borealis) have been conducted annually in the Barents Sea and the Svalbard area since 1980 by Norwegian research institutes. The surveys have been conducted in the period April to ... -
Explotation and state of stock

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 ... -
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, ... -
Final report on the ICES-coordinated accoustic survey of herring stocks in 1979 : Aberdeen, U.K., 22 - 24 January 1980.

Fishing experiments with an alternative longline bait based on nylon bags
(ICES CM Documents;1987/B:19, Working paper, 1987)This report describes two fishing trials using an alternative longline bait, one in the fishery for torsk and ling, the other in the fishery for cod and haddock. A bait based on fine-meshed nylon bags as reinforcement ... -
Full scale tests of improved longline gear
(ICES CM Documents;1985/B:45, Working paper, 1985)A new type of bottom set longline was tested in trials during the cod fishery off Finnmark November-December 1984. This gear differed from traditional longloine, by being rigged with swivel-mounted monofilament gangions ... -
Geostatistical analysis of acoustic survey data on 0-group herring in a fjord
(ICES CM Documents;1992/D:10, Working paper, 1992)An essentially pure aggregation of 0-group herring in Altafjord in northern Norway was acoustically surveyed on each of the first three days of December 1991. Measurements were made at 38 kHz during each survey and at ... -
