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 ... -
The agreed recovery plan in the management of Norwegian spring-spawning herring
(ICES CM documents, Working paper, 2003)In October 2001 the management agency (Coastal States) for Norwegian spring spawning herring agreed to a recovery plan which will become operative if the spawning stock falls below Bpa. The main element in this recovery ... -

Aluminium accumulation on eggs and hatching system during the incubation period - an important cause of variable hatching success ?
(ICES CM Documents;1984/F:27, Working paper, 1984)Groups of rainbow trout eggs were incubated in duplicate in trays with PVC screens and original aluminium screens. During incubation aluminium bound to sediments was deposited on eggs and hatching systems. By adding ... -
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, ... -
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 ... -
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 ... -
Application of larval fish population dynamics in enclosure systems in production of marine fish fry
(ICES CM Documents;1983/F:6, Working paper, 1983) -
The application of tank experiments to the study of reproductive potential in teleosts using Gadus morhua as a test model
(ICES CM documents, Working paper, 2000)Age-based population assessments (VPA) have often failed to show a clear relationship between spawning stock biomass and either recruitment or biomass estimated from annual egg production. Recent work has shown that the ... -

Are Norwegian fjords important spawning areas for anglerfish (Lophius piscatorius)?
(ICES CM documents;2007/K:17, Working paper, 2007)The knowledge about anglerfish spawning in the northeastern Atlantic is limited. Mature females are rarely seen in the major commercial fisheries within the area, and the general perception has been that the main spawning ... -
Are there potential resources of Iceland scallops (Chlamys islandica) in the Barents Sea ?

Artificial hatching substrate and different time of transfer to startfeeding: Effect on growth and protease activities of the Atlantic salmon (Salmo salar).
(ICES CM Documents;1984/F:22, Working paper, 1984)Groups of Atlantic salmon (Salmo salar) eggs were hatched in a Californian hatching system with and without an astro-turf artificial substrate, and food was presented at four different points in development. Dry weight ... -
Artificial hatching substrate in the mass rearing of larval Atlantic salmon (Salmo salar)
(ICES CM Documents;1984/F:30, Working paper, 1984)Eggs from individual Atlantic salmon (Salmo salar) were hatched in a Californian hatching system with and without an astro-turf artificial substrate and growth during the first 200 days following hatching was ... -
Artificial hatching substrate, effect on RNA / DNA ratio and protein retention during the yolk-sac period of Atlantic salmon (Salmo salar)
(ICES CM Documents;1985/F:31, Working paper, 1985)Genetical groups of Atlantic salmon (Salmo salar) were hatched in a Caiifonian hatching system with and without an astro-turf artificial hatching substrate, and were later transfered to separate feeding units. The ...
