An evaluation of survey design for estimating the food consumption by fish
(ICES CM Documents;1991/D:15, Working paper, 1991)The effect of survey design on the precision of estimates of average fish stomach contents is examined. The contribution to the total variance from within and between tow variability in stomach contents is evaluated, ... -
An evaluation of the IMR Summer Bottom Trawl Survey in the Barents Sea
(ICES CM Documents;2001/P:16, Working paper, 2001)Summary: A committee was formed to evaluate the Institute of Marine Research summer survey in the Barents Sea, which has been conducted annually since 1995. The primary focus of the committee was the survey’s importance ... -
An ICES workshop on biological effects in pelagic ecosystems (BECPELAG): overview of the programme
(ICES CM Documents;2002/X:2, Working paper, 2002)The ICES biological effects monitoring in pelagic ecosystems workshop (BECPELAG) is a multi-national, multi-dicipline workshop aimed at establishing suitable techniques for monitoring the effects of contaminants on pelagic ... -
An ICES workshop on biological effects in pelagic ecosystems (BECPELAG): summary of results and recommendations
(ICES CM Documents;2002/X:13, Working paper, 2002)During and after three previous workshops, biological effects methods have been compared and refined. The first was held in Oslo in 1988, the second at Bermuda in 1990, and the third in Bremerhaven in 1992. All three ... -

An integrated database for marine research
(ICES CM Documents;1993/D:23, Working paper, 1993)In 1992 an integrated model for marine research data was developed at the Institute of Marine Research. Traditionally, the marine research disciplines collect data from their own fields, normally used in a limited context. ... -
An intership sonar calibration experiment in the Norwegian Sea
(ICES CM Documents;1996/B:22, Working paper, 1996)When migrating in the Norwegian Sea in spring and summertime, the Norwegian spring spawning herring will be surveyed by vessels from four nations. Because the herring may occur in schools close to the surface, use of ... -
Analysis of CPUE from the Norwegian bottom trawl fleet
(ICES CM Documents;2000/W:14, Working paper, 2000)Commercial logbooks with catch and effort data have been collected and recorded by the Norwegian Direcorate of Fisheries since 1971. Annual age segregated CPUE indices are calculated with different methods for North-east ... -
Analysis of spatial variability of Georges Bank haddock (Melanogrammus aeglefinus) from trawl survey data using a linear regression model with spatial interaction
(ICES CM Documents;1990/D:36, Working paper, 1990)A regression model with spatially autocorrelated errors is used to test if there is systematic spatial variation across the study area in haddock catch per tow data from the NEFC annual fall survey from 1963 - 1987. A ... -
Anglo-Norwegian oil programme - intercalibration of analytical methods
(ICES CM Documents;1978/E:22, Working paper, 1978)An attempt has been made to intercalibrate the analysis of three groups of aromatic compounds present in a sample of Ekofisk crude oil using gas chromatography - mass spectography. The results are not as good as was ... -
Angular distribution of overwintering Norwegian spring spawning herring
(ICES CM documents, Working paper, 1994)When plankton production drops off in the fall, adult Norwegian spring spawning herring migrate to two fiords in northern Norway with stable water masses with low temperature and predation. In the wintering areas, the ... -

Antibacterial treatment procedures of eggs of halibut (Hippoglossus hippoglossus L.)
(ICES CM Documents;1990/F:39, Working paper, 1990)Halibut eggs were surface disinfected with a iodophor one day before hatching, and mortality and larval development was recorded until the time of first feeding. The groups exposed to higher concentrations of disinfectant ... -
Antibiotic treatment and dose-response of bacterial activity associated with flatfish eggs
(ICES CM Documents;1987/F:19, Working paper, 1987)Newly stripped and fertilized eggs from Plaice (Pleuronectes platessa) and Atlantic Halibut (Hipppoglossus hippoglossus) were incubated in 34 ppt sea water. 150 eggs (Plaice), 30 eggs (Halibut) or 20 glass beads were ... -

Appetite feeding experiments with cod - preliminary results
(ICES CM Documents;1980/F:20, Working paper, 1980)Various size groups of cod were kept in periods of 3 to 4 weeks in ad lib. feeding experiments at deprivation times from 4 to 48 hours. Ration size varied from 0.4 to 6.2 % (wet weight) per meal in the series. Average ... -

Application of Coded Wire Tagging Technology in Pacific Herring to Investigate Stock Structure and Migration
(ICES CM documents, Working paper, 2001)Tagging of Pacific herring in British Columbia has a long history dating to the mid-1930s but uncertainty in tag recovery locations and low tag return rates limited the utility of these studies. Currently, a larger and ...
