A biotest system for optimalization of environmental parameters for production of halibut fry
(ICES CM Documents;1987/F:21, Working paper, 1987)A system for controlled testing of different environmental parameters in seawater was made. Both the biotest system and an experimental setup using larvae of the Atlantic Halibut (Hippoglossus hippoglossus L.) are described. -
A comparison of growth rate of halibut larvae (Hippoglossus hippoglossus L.) fed wild zooplankton and enriched Artemia
(ICES CM Documents;1990/F:60, Working paper, 1990)Halibut larvae at an age of 267 day degrees post hatching, were reared through first feeding, outdoors in 100 l plastic bags. There were three feeding regimes: wild zooplankton, Artemia enriched on the algae Isochrysis ... -
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 ... -
A multiple approach to behaviour studies of salmon reared in marine net pens
(ICES CM Documents;1988/F:15, Working paper, 1988)The behaviour of Atlantic salmon in culture was lnvestigated by various techniques with the ultimate goal of characterlzing the behaviour typical for a situation with rapid growth. Differences in behaviour between and ... -
A pilot study of halibut larvae (Hippoglossus hippoglossus L.) reared from start feeding to metamorphosis on diets of wild zooplankton and Artemia
(ICES CM Documents;1990/F:52, Working paper, 1990)Halibut larvae ready to start feed were placed in two outdoor tanks of 7 m^3. The larvae in one tank were fed wild zooplankton throughout the whole period, and the larvae in the other tank were fed wild zooplankton from ... -
A system for online assessment of fish welfare in aquaculture
(ICES CM documents;2008/R:18, Working paper, 2008)Aquaculture sea cages can now be more than 30 meters deep. It has therefore become next to impossible for fish farmers to form a complete picture of the welfare situation of the fish. It is consequently all ]important ... -
The abundance of sprat eggs and larvae in the Langesund and the Oslofjord areas, south-eastern Norway, 1974-1978.
(ICES CM Documents;1979/H:60, Working paper, 1979)Sprat eggs and larvae were sampled through monthly cruises in two fjordsystems of South Eastern Norway from 1974 to 1978. The abundance and distribution of the eggs and larvae were studied. Eggs were found throughout ... -
Acoustic abundance estimates of the Icelandic stock of capelin, October 1978 - January 1980.
(ICES CM Documents;1980/H:63, Working paper, 1980)During the period October 1978 - January 1980 several estimates of the size and yearclass composition of the Icelandic capelin stock were obtained by the acoustic method. Surveying was carried out in October 1978, ... -
Acoustic estimates of abundance-at-age of juvenile Norwegian spring-spawning herring (Clupea harengus L.) in the Barents Sea from 1983 to 1993
(PINRO-IMR Symposium, Conference object, 1995)The first year-class of Norwegian spring-spawning herring to enter the Barents Sea in significant numbers since the stock collapse in the late 1960'ies was the 1983-cohort. Regular acoustic surveys have been carried out ... -
Age of Atlantic halibut larvae (Hippoglossus hippoglossus L.) at first feeding
(ICES CM Documents;1990/F:53, Working paper, 1990)Halibut larvae at different age (150 to 315 day-degrees) were transferred to outdoor startfeeding tanks each with two internal plastic bags (100 litre). The larvae were fed wild zooplankton. One bag was sampled after 24 ... -
Aggression and growth of atlantic salmon in different stocking densities
(ICES CM Documents;1976/E:37, Working paper, 1976) -
Aggression and growth of different populations of Atlantic salmon parr
(ICES CM Documents;1978/M:24, Working paper, 1978)In order to study aggression and growth of salmon parr of different populations and the possible effect of fin-clipping on these traits hatchery reared parr originating from three populations (2 Norwegian, 1 Swedish) were ... -
Application of larval fish population dynamics in enclosure systems in production of marine fish fry
(ICES CM Documents;1983/F:6, Working paper, 1983) -
Behaviour aspects of fish in relation to oil platforms in the North Sea.
(ICES CM Documents;1979/B:27, Working paper, 1979)Fish distribution around structures of the Ekofisk oil field in the central North Sea was investigated by means of gillnet fishing, longlining, jigging and echosurveying. The studies were carried out during one week in ... -
Behaviour of saithe penned in different densities.
(ICES CM Documents;1980/B:26, Working paper, 1980)In Norway purse seine catches of live saithe are towed to the coast and kept in net pens until the fish can be processed by the fishing industry. During penning - especially during "short-time" penning - the quality of ... -

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. ... -
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 ...
