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 ... -

Evidence of sampling induced biases in mortality estimates from experiments investigating mortality in fish escaping from towed fishing gears
(ICES CM Documents;2002/V:25, Working paper, 2002)When studying escapes from trawl codends and other selective devices, the most common method of capturing or ‘sampling’ escaping fish is using a codend cover (Figure 1). This paper will summarise a programme of work providing ... -

Experiences in making acoustic measurements in a mesocosm with Calanus finmarchius
(ICES CM Documents;1997/FF:11, Working paper, 1997)In connection with a larger study of the effects of nutrification and turbulence on primary and secondary production, acoustic measurements have been made in the water volume defined by floating, vertically oriented, ... -
Experiences using the constraint technique on bottom trawl doors
(ICES CM Documents;1993/B:18, Working paper, 1993)The constraint technique, i.e. using a rope between the warps, has the intention of minimizing the variability in trawl geometry with depth. Experiments with the constraint technique on two different bottom trawls used ... -

Experiments with cod pots as an alternative to gill-nets in the Varanger fjord in april-june and october-december 1996
(PINRO-IMR Symposium, Conference object, 1997)A newly developed cod pot (two-chamber pot) has been tested in the VarangerfJord area as an alternative to gill-net, with the purpose to reduce the periodically large unaccounted mortality of king crab in the gill-net ... -

Field experiences with a new miniature vector averaging current meter
(ICES CM Documents;1991/C:20, Working paper, 1991)For several years Inst. of Marine Research Bergen has been developing miniaturized modular current meters. Thanks to major improvements in electronic component technology in recent years, a physically small current meter ... -
Field intercalibrations of echo integrator systems
(ICES CM Documents;1978/B:25, Working paper, 1978)The paper reviews intercalibrations of echo integrators carried out in 1975 - 1977 where Norwegian research vessels have participated. Analog and digital integrator performance is compared, and methods to make integrator ... -

Fish avoidance of research vessels and the efficacy of noise-reduced vessels: a review
(Journal article; Peer reviewed, 2012-10-19)It has long been recognized that fish can avoid approaching vessels and that these behaviours can bias fishery surveys. Underwater noise is considered the primary stimulus, and standards for research vessel noise have been ...
