A genetic marker for artificially reared cod (Gadus morhua L.)
(ICES CM Documents;1987/F:22, Working paper, 1987)Artificially reared cod at the Aquaculture Station Austevoll on the west coast of Norway, were screened for genetic markers by using biopsies of white muscle, individual tags and enzyme genotype as determined by starch ... -
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 ... -
Deepwater flowthrough as a temperature stabilizer in rearing of halibut (Hippoglossus hippoglossus) fry
(ICES CM Documents;1987/F:16, Working paper, 1987)Through the period of yolk sac absorption, halibut larvae were kept in plastic bags in plastic basins with flowthrough of deepwater. When maintaining sufficient flowthrough, in this period the temperature in the bags ... -
Results of investigations of migration pattern of artificially reared coastal cod (Gadus morhua L.) in western Norway
(ICES CM Documents;1987/F:26, Working paper, 1987)Investigations of the migration pattern have been a central part in an ongoing enhancement study of cod in western Norway. In Sept. - Nov. 1983, 20,947 juvenile, basin-reared cod fry were tagged and released at three sites ... -
Natural and cultivated zooplankton as food for halibut (Hippoglossus hippoglossus) larvae
(ICES CM Documents;1987/F:17, Working paper, 1987)Natural zooplankton were pumped into a collector and size-fractionated. The zooplankton smaller than 350 ym were fed on a diatom dominated algal suspension cultured in 3 m deep out-door plastic bags. Halibut larvae ... -
Morphological development of halibut (Hippoglossus hippoglossus) larvae with special reference to mouth development and metamorphosis
(ICES CM Documents;1987/F:18, Working paper, 1987)Halibut (Hippoglossus hippoglossus) larvae were raised from hatching to beyond metamorphosis in 11.5 m3 plastic bags with a temperature stable around 6°C. Standard length, myotome height, eye diameter and yolk sac length ... -
Winter / late autumn distribution of nutrients in the North Sea
(ICES CM Documents;1987/C:24, Working paper, 1987) -
The equivalent beam angle and its effective value when applying an integrator threshold
(ICES CM Documents;1987/B:35, Working paper, 1987)In a noise-limited echo integration system, a threshold is applied in order to avoid the contribution from noise. As the signal-to-noise ratio decreases with range, the effective observation volume for small targets is ... -
Climatic changes at the North Sea plateau during 1967 - 1984
(ICES CM Documents;1987/C:17, Working paper, 1987)The average temperature and salinity in the water masses with S> 35.0 in the Utsira and Hanstholmen sections for the periode 1967-1984 is presented. The influence of the mid 1970`s salinity anomaly at the North Sea ... -
Testing of a new hook design in the longline fishery for tusk (Brosme brosme) and ling (Molva molva)
(ICES CM Documents;1987/B:20, Working paper, 1987)The EZ-Baiter Circle hook which is a hybrid design between the classical J- and Circle hook shapes, is developed to provide a more effective hook for use in mechanized longline systems. In comparative fishing trials, ... -
The effect of different sweep lengths on length composition of bottom sampling trawl catches
(ICES CM Documents;1987/B:16, Working paper, 1987)Abundance estimates of North-east Arctic cod and haddock are given annually on the basis of combined bottom trawl and acoustic surveys. Both survey methods use data from bottom trawl catches in the calculations. The ... -
Report of the Working Group on Shelf Seas Oceanography [Bergen, 12 -14 May, 1987]

Swivel connected gangions in mechanized longlining - effect on cath rates and operation
(ICES CM Documents;1987/B:18, Working paper, 1987)Multifilament longline with swivel connection between gangions and mainline were compared with traditionally rigged gear on a vessel equipped with a mechanized longline system. The swivel-lines were adapted to the ... -
Assessment of potential oil pollution damages on fish resources. Some examples from the area outside mid-Norway
(ICES CM Documents;1987/E:13, Working paper, 1987)Detailed mapping of fish eggs and larvae both in space and time is essential knowledge when realistic assessments of oil pollution damages to the fish resources are established. The text explain with some examples our ... -
Report of the Meeting of Analysts Participating in the Hydrocarbon Intercalibration Programme [Copenhagen, 13 -14 February, 1987]

Report of the Working Group on Fisheries Acoustic Science and Technology [Seattle, 26 -28 June, 1987]

Position prediction of herring schools in purse-seine capture situations
(ICES CM Documents;1987/B:10, Working paper, 1987)Sonar observations of herring schools in the North Sea and along the Norwegian Coast reveal a rather constant swimming behaviour of individual schools in purse-seine capture situations. On the basis of this a method for ... -
Synergistic effects of different baits on the same hook in the longline fishery for hake (Merluccius merluccius) and torsk (Brosme brosme)
(ICES CM Documents;1987/B:39, Working paper, 1987)The effects of a combination of different baits on the same hook were tested in two different situations. A bait combination of sardine (Sardina pilchardus) and mackerel (Scomber scombrus) was used to catch hake (Merluccius ... -
