Calibration reflector
(ICES CM Documents;1989/B:4, Working paper, 1989)Calibration of scientific echo sounders and integrators entails, inter alia, measurement of the dynamic range. This can be done by repeating on-axis measurements of echoes from each of two different standard targets. ... -
Can a bioenergetics model explain growth of the northeast Arctic cod?
(ICES CM Documents;1994/G:7, Working paper, 1994)For the period 1984 to 1991, the individual maximum daily consumption in calories (cmax) based on 33000 cod stomach samples is given by the power equation: Cmax = 68.84 · W ^0,934 where W represents the total fish ... -
Can Pitch & Roll DST distinguish between pelagic and demersal behaviour of adult Greenland halibut
(ICES CM documents, Conference object, 2006) -
Can subjective evaluation of echograms improve correlation between bottom trawl and acoustic densities?
(ICES CM documents, Working paper, 2004)Direct comparison of acoustic densities and trawl catches involves fundamental difficulties related to species and size selectivity of the trawl and efficiency of the acoustic instrumentation. In some surveys, therefore, ... -
Can the precision of bottom trawl indices be increased by using simultaneously collected acoustic data? The Barents Sea experience
(ICES CM documents, Conference object, 2006) -
Can trawling effort be identified from satellite-based VMS data?
(ICES CM documents, Working paper, 2006)Data from satellite-based vessel monitoring systems (VMS) can, in principle, be used to measure fishing effort with a high spatiotemporal resolution. However, it can be difficult to separate between fishing activity and ... -
Cannibalism as a factor regulating year class strength in the Norwegian spring-spawning herring stock
(ICES CM Documents;1992/H:14, Working paper, 1992)The feeding area of the Norwegian spring-spawning herring stock is at present situated in the north-eastern parts of the Norwegian Sea. The eastern parts of the feeding area overlaps with the distribution of drifting ... -
Capture and handling of fish for electronic tagging - a review and a new non-intrusive capture method.
(ICES CM documents, Working paper, 1999)While tagging procedures are described in details the capture and handling of experimental fish prior to tagging is not given the same attention in most papers. However, traumas that originate from the capture and handling ... -
Capture techniques for wrasse (Labridae)
(ICES CM Documents;1993/B:22, Working paper, 1993)An increasing demand for wrasse used as cleaner-fish for louse control in salmon farming has led to a new fishery for different wrasse species - particularly goldsinny, rock-cook and corkwing wrasse. This paper describes ... -
Case histories and new approaches to planning and modelling for Norwegian mariculture
(ICES CM Documents;1994/F:26, Working paper, 1994)To promote a sustainable mariculture industry the environmental impact of the individual fish farm must be adjusted to the holding capacity of the site. The present regulation systems seems insufficient in achieving this. ... -
Catch and effort data of the lobster fishery in south eastern Norwegian waters during 1928-1975
(ICES CM Documents;1976/SM:1, Working paper, 1976) -
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 ... -
Catch statistics of lobster (Homarus vulgaris L.)
(ICES CM Documents;1973/K:42, Working paper, 1973) -
Catch, Effort and Composition of the Norwegian Winter Herring Fishery
(ICES CM Documents;1961/43, Working paper, 1961) -
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 ... -
The catching efficiency of cod gillnets with different hanging ratio (E) and different floatline buoyancy.
(ICES CM Documents;1979/B:19, Working paper, 1979)The floatline buoyancy seems to influence the catching efficiency of cod gillnets. Trials with different byoyancies in cod gillnet fishing in Northern Norway gave the best catches with a buoyancy of about 65 grammes per ... -
Catfish - King of the sea
(ICES CM Documents;1995/B:16, Working paper, 1995)During an acoustic tagging experiment on cod in the Barents Sea in March 1995 a hierarchy between different fish species was revealed, and the catfish (Anarhichas sp.) was observed to be dominant in relation to cod and ... -
Causes of variation in carcass traits of Atlantic salmon (Salmo salar)
(ICES CM Documents;1984/F:25, Working paper, 1984)The aim of the present study was to reveal causes of variation in carcass traits of farmed Atlantic salmon (Salmo salar). During slaughtering of one year class Atlantic salmon, composed of half sib and full sib groups, ... -
