0-group saithe in the west Spitsbergen area.
(ICES CM Documents;1971/F:20, Working paper, 1971) -
1994 ICES coordinated acoustic survey of ICES Divisions IVa, IVb, VIa and VIIb
(ICES CM Documents;1995/H:15, Working paper, 1995)Summary: Six surveys were carried out during late June and July covering most of the continental shelf North of 54°N in the North Sea and Ireland to the west of Scotland to a northern limit of 62°N. The eastern edge of ... -
A bio-economic analysis of harvest control rules for the Northeast Arctic cod fishery
(Journal article; Peer reviewed, 2012-12-12)Harvest control rules (HCRs) have been implemented for many fisheries worldwide. However, in most instances, those HCRs are not based on the explicit feedbacks between stock properties and economic considerations. This ... -
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 combined fish larval, phytoplankton and oceanographic survey in the Skagerrak and the Kattegat in April 1983
(ICES CM Documents;1983/L:26, Working paper, 1983) -
A comparison between three Atlantic salmon river stocks; using classical population genetics, differences in life history traits and performance in sea ranching
(ICES CM Documents;1997/P:13, Working paper, 1997)Characterisation of stocks is essential for fisheries and environmental management in order to conserve genetic diversity. However, classical populationgenetic methods frequently fail to document stock differences. In ... -
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 framework for improving accuracy in fisheries data used in stock assessments
(ICES CM documents;2008/N:27, Working paper, 2009) -
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 method to estimate the annual larval production of the Norwegian spring-spawning herring (Clupea harengus L.)
(ICES CM Documents;1997/BB:1, Working paper, 1997)A comprehensive survey in the larval distribution area of Norwegian spring-spawning herring along the Norwegian west coast was carried out annually by the Institute of Marine Research, Bergen in the years 1986-1990. ... -
A new model for simulating growth in fish
(Journal article; Peer reviewed, 2014-01-16)A real dynamic population model calculates change in population sizes indepen- dent of time. The Beverton & Holt (B&H) model commonly used in fish assessment includes the von Bertalanffy growth function which has age or ... -
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 preliminary Investigation on Shelf Edge and Deepwater Fixed Net Fisheries to the West and North of Great Britain, Ireland, around Rockall and Hatton Bank.
(ICES CM documents;2005/ N:07, Working paper, 2005)Since the mid-1990s, a fleet of up to 50 vessels have been conducting a gillnet fishery on the continental slopes to the West of the British Isles, North of Shetland, at Rockall and Hatton bank. These vessels, though ... -
A preliminary report on the natural occurrence and ecology of Atlantic halibut (Hippoglossus hippoglossus) postlarvae and young immature stages
(ICES CM Documents;1987/F:38, Working paper, 1987)Surveys designed to capture Atlantic halibut, Hippoglossus hippoglossus, postlarvae and young immatures were carried out around Sørøya in North Norway in 1985, 1986 and 1987. Hydrographical conditions and the current ... -
A preliminary study of microstructure in otoliths of seacaught mackerel (Scomber scombrus L.) larvae
(ICES CM Documents;1990/H:4, Working paper, 1990)Mackerel larvae have been sampled during two cruises south of lrland, in May and June 1989 and preserved in ethanol. The microstructure of the otoliths (sagittae) from the mackerel larvae have been examined. There is a ... -
