Bycatch of juvenile fish in the shrimp fishery - management based on bioeconomic criteria
(ICES CM Documents;1994/T:14, Working paper, 1994)The bycatch of juvenile fish can be a major problem in fisheries with small meshed trawls, such as fisheries for shrimp, (Pandalus borealis). A sorting grid that effectively removes most of the undersized fish has been ... -
Catch and effort data of the lobster fishery in south eastern Norwegian waters during 1928-1975

Catch comparison between rockhoppers and bobbins ground gear on the Norwegian bottom sampling trawl
(ICES CM Documents;1988/B:31, Working paper, 1988)In a study aimed at improving the reliability of the Norwegian bottom sampling trawl, comparative fishing between standard bobbins gear and rockhopper ground gear were carried out in the Barents Sea. The catch ratios ... -
Catch statistics and life history of shrimp, Pandalus borealis, in the Jan Mayen area
(ICES CM Documents;1996/K:11, Working paper, 1996)The Norwegian shrimp (Pandalus borealis) fisheries in the Jan Mayen area in the North East Atlantic started in 1974. The catches reached 2000 tons in 1985. Since 1986 the catches decreased, but lately they have increased ... -

Catches of Greenland halibut (Reinhardtius hippoglossoides) in ghost fishing gillnets on the Norwegian continental slope
(ICES CM Documents;2000/J:8, Working paper, 2000)Catches in deliberately “lost” gillnets were studied during a ten-day cruise conducted at Storegga 70 nm off the coast of mid-Norway in July 2000. Gillnet fleets were deployed at depths of between 537 and 677 m, and soak ... -
Changes in abundance and distribution of the Barents Sea long rough dab, hippoglossoides platessoides (Fabricius) during the period 1980- 1992
(ICES CM Documents;1993/G:36, Working paper, 1993)Abundance and biomass of long rough dab in tha Barents Sea and adjacent waters were assessed from bottom trawl survey data from research surveys by Norway and Russia, during the period 1980- 1992. Although there was no ... -
Changes on horse mackerel (Trachurus trachurus) catch distribution in the Northeast Atlantic
(ICES CM Documents;1996/S:26, Working paper, 1996)The distributions of international commercial catch data were mapped by ICES rectangle and quarter from 1983-1994. These indicate a northward expansion of horse mackerel distribution in the Northeast Atlantic since 1987. ... -
Coastal and fjord resources off Finnmark and Troms counties, Norway, based on the 1992 survey
(ICES CM Documents;1994/G:38, Working paper, 1994)In 1992 an acoustic survey in fjords and shelf areas off Finnmark and Troms, two counties in northern Norway, was made to estimate the total biomass of cod, haddoc, saithe, redfish species and herring to be 876.000 tonnes. ... -
Comparison Between Catch per Unit Effort in the Norwegian Gill-net and Purse-seine Fishery for Herring

Comparison of the capture efficiency of 0-group fish in pelagic trawls
(PINRO-IMR Symposium, Conference object, 1995)In 1992 and 1993 experiments were carried out during the international 0-group fish surveys in order to study the capture efficiency of two pelagic trawls. The catches of the standard sampling trawl were compared with ... -
Comparisons between size distribution in surveys and commercial catches: a useful tool for monitoring changes in the size selection in the fisheries?
(IMR/PINRO Joint Report Series, Conference object, 2001)A method is proposed for using fish distributions from standarized research surveys for estimating relative selection in the fisheries. The method is applied on data for North-east arctic cod in the 1990-ies. Survey-related ... -

Day and night fish distribution pattern in the net mouth area of the Norwegian bottom-sampling trawl
(Journal article; Peer reviewed, 1990)A high-frequency scanning sonar, mounted as a net sonde, was used to study fish behaviour in the mouth area of the Norwegian bottom-sampling trawl. Fish distribution patterns were significantly different by day and night. ... -

Density dependent catchability in bottom trawl surveys
(ICES CM Documents;1997/W:16, Working paper, 1997)Fish form schools, layer or patches in which the individual fish's behaviour is not independent of its neighbours movements. On the other hand, at low densities fish may have the freedom to act as single individuals ...
