Preliminary Tests of a Shrimp-fish Separator Section for Use in Shrimp Trawls
(ICES CM Documents;1984/B:12, Working paper, 1984)A prototype shrimp-fish separator to be installed between the body and codend of a shrimp trawl was designed and constructed. The separator uses large square meshes to provide an escape path for fish, while funnels ... -
Present ssatus of an intensive cod larvae rearing experiment at Austevoll
(ICES CM Documents;1981/F:13, Working paper, 1981)Cod yolk sac larvae were attempted start fed on natural plankton in plastic pens. The majority of the larval groups were also hatched in these pens. None of the sampled larvae had ingested feed, and all groups died out ... -

Prey consumtion by Barents sea harp seals in the period 1990-2005
(ICES CM documents, Working paper, 2006)The Barents Sea ecosystem has experienced major fluctuations in species abundance in the past 20-30 years. The mechanisms behind these fluctuations are complex and arise from numerous interactions between species and the ... -
Prey selection of early juvenile cod (Gadus morhua L.) in the Barents Sea

Prey-specific gastric evacuation of Norwegian spring spawning herring (Clupea harengus)
(ICES CM Documents;2004/P:39, Working paper, 2004)Gastric evacuation rates have earlier mainly been measured based on laboratory experiments. The aim of this study is to obtain information of gastric evacuation rates when the herring are feeding in their natural environment. ... -
Primary growth increments in otoliths of cod larvae (Gadus morhua L.) of the Arcto-Norwegian cod stock
(ICES CM Documents;1981/G:54, Working paper, 1981)Primary growth increments are laid down in the otoliths of cod larvae living in a habitat where the light intensity is above the light threshold for visual feeding during 24 hours, and in which the larvae were observed to ... -
Primary growth rings in Blue Whiting otoliths
(ICES CM documents;1979/H:32, Working paper, 1979)To approach the problem of ageing blue whiting, acetat prints of the otoliths have been studied through a microscope. Primary growth rings have been counted, and provided that these are formed daily, the hatching time could ... -
Primary growth rings in otoliths of the Barents Sea capelin

Production experiment of halibut fry (Hippoglossus hippoglossus) in silos
(ICES CM Documents;1987/F:42, Working paper, 1987)Silos with conical bottoms and a volume of approx 3.5 m3 are tested as storing units for halibut yolk-sac larvae. The silos were run in three different ways: A: Stagnant water with a saltplug till day 10 and later slow ... -
Production experiment of halibut fry in large enclosed water columns
(ICES CM Documents;1986/F:19, Working paper, 1986)Halibut eggs were hatched in 21 floating enclosures and the larvae stored through the yolk sac period under 5 different environmental conditions, each with 4 parallels. The effect of the different environments was ... -
Production of juvenile flatfish species in different sized mesocosms
(ICES CM Documents;1985/F:65, Working paper, 1985)Mesocosm studies with larvae of halibut (Hippoglossus hippoglossus), sole (Solea solea) and turbot (Scophthalmus maximus) was carried out at Austevoll Aquaculture Station and at Flødevigen Biological Station in 1985. ... -
