A stripping method for Atlantic halibut (Hippoglossus hippoglossus L.)
(ICES CM Documents;1987/F:40, Working paper, 1987)A stripping-board was built and tested on a broodstock of halibut ranging from 8 to 150 kg body weight. The smooth surface of the neophrene mattress minimized the loss of mucus and reduced the stripping stress ... -
A study of genetic variation in northeast Atlantic harp seals (Pagophilus groenlandicus)
(ICES CM Documents;1991/N:5, Working paper, 1991)16 enzymes were examined for genetic studies of the harp seal population structure in the Northeast Atlantic. Muscle and liver samples were collected in the West Ice off Jan Mayen and in the Eastern Barents Sea in 1987, ... -
Abundance and mortality of Northeast Arctic cod and haddock during their first years of life
(ICES CM Documents;2010/C:04, Working paper, 2010)For Northeast Arctic cod and haddock in the Barents Sea, long time series of year-class abundance are available at several stages before they recruit to the fishery, i. e. before they reach age 3. Several studies have ... -
Abundance and productivity of the pelagic ecosystem along a transect across the northern Mid Atlantic Ridge in June 2003
(ICES CM documents;2008/C:12, Working paper, 2008)A research cruise was conducted into the Irminger Sea west and southwest of Iceland on the Icelandic vessel Árni Friðriksson, from 4-30 June 2003, investigating redfish, Sebastes mentella, other pelagic fishes, zooplankton, ... -
Abundance estimates of Barents Sea capelin
(ICES CM Documents;1964/119, Working paper, 1964) -
Abundance estimation with echo integrator of arctic cod on the spawning grounds in Lofoten 1972
(ICES CM Documents;1972/F:37, Working paper, 1972) -
Abundance indices for the Arcto-Norwegian cod for the period 1979 -1986 based on investigations in June/July
(ICES CM Documents;1986/G:75, Working paper, 1986)Postlarvae Surveys have been carried out in the western part of the Barents Sea in June/July since 1977. The aim of the investigations has been to study the distribution pattern of fish larvae and their relation to the ... -
An account of the Norwegian coalfish investigations with special reference to the tagging experiments
(ICES CM Documents;1961/125, Working paper, 1961)Total Norwegian landings of coalfish during the last decade averaged 66 000 tons annually. The main types of gear are purse seine, gill nets and otter trawl. Statistics of quantities by month and area are available, but ... -
Accumulation and disposal of some byproducts from vinylchloride production in cod liver
(ICES CM Documents;1971/E:10, Working paper, 1971) -
Acoustic abundance estimation of the Icelandic stock of capelin : 1978-1982
(Working paper, 1982)During the period October 1978 - february 1982 several abundance estimates and yearclass composition of the Icelandic capelin stock were obtained by acoustic methods. Surveying has been carried out in July-Agust, September, ... -
Acoustic abundance estimation of wintering Norwegian spring spawning herring, with emphasis on methodological aspects
(ICES CM Documents;1994/(B+D+G+H):1, Working paper, 1994)The spawning component and part of the juvenile stock of Norwegian spring spawning herring have been wintering in a fjord system in northern Norway in recent years. Conditions for measuring the stock size have been ... -
Acoustic and Bottom Trawl Surveys; How Much Information Do They Provide for Assessing the Northeast Arctic Cod Stock?
(ICES CM documents, Working paper, 1999)Acoustic and bottom trawl surveys of the Northeast Arctic cod stock provide fishery independent estimates of trends in abundance and population characteristics. Given the recent uncertainties in the catch based assessment ... -
Acoustic estimates of spawning cod off Lofoten and Møre in 1985
(ICES CM Documents;1985/G:66, Working paper, 1985)The annual surveys on the spawning stock of North-east Arctic cod were carried out in the Lofoten and Møre areas in March- April 1985. These surveys were undertaken to estimate the size and age structure of the spawning ... -
Acoustic estimates of spawning cod off Lofoten in 1986
(ICES CM Documents;1986/G:79, Working paper, 1986)The annual survey on the spawning stock of North-east Arctic cod were carried out in the Lofoten area in March 1986. This survey was undertaken to estimate the size and age structure of the spawning cod on the main ... -
Acoustic extinction in dense herring layers, measured from a bottom-mounted transducer
(ICES CM documents, Working paper, 2006)Herring is often found in dense aggregations or schools, and acoustic shadowing is thus a problem in acoustic survey estimates. Knowledge of the attenuated echo intensity in herring aggregations is essential for correcting ... -
Acoustic measurements of schooling herring. Estimation of school biomass and target strength
(ICES CM Documents;1988/B:26, Working paper, 1988)The connections between reflected echo energy and dimensions of fatty herring schools were studied by a combination of multibeam sonar and a calibrated echo integration unit. A relation between the area and the biomass ... -
Acoustic properties of Salpa thompsoni.
(ICES CM documents;2009 / I:01, Working paper, 2009)Salps are common members of the world oceans planktonic community (Madin, et.al., 2006). In the southern ocean, both krill (Euphausia superba) and salps (Salpa thompsoni) can occur in dense aggregations (Loeb et al, 2009, ... -
