Dynamics of wintering Norwegian spring-spawning herring at the entrance to Tysfjorden, December 1996
(ICES CM Documents;1997/CC:16, Working paper, 1997)The entrance region to Tysfjorden was acoustically surveyed a total of eleven times during the December 1996 abundance survey of the spawning stock of Norwegian spring-spawning herring (Clupea harengus). The observations ... -
Dødelighet av sild etter trenging i not : Mortality of herring after being crowded in a purse seine
(Havforskningsnytt, Working paper, 2009)When purse seining for herring, catch regulation have traditionally been done by discarding all or part of the catch if it is too big, or if the size or quality of the herring does not match requirements. Net burst is also ... -
Early development of Northeast Arctic greenland halibut (Reinhardtius hippoglossoides)
(ICES CM Documents;1998/O:27, Working paper, 1998)The early development of the Greenland halibut (Reinhardtius hippoglossoides) has never been described in detail. This study contains some preliminary notes on the egg development of the Northeast Arctic Greenland halibut ... -
Effect of size-selective mortality on growth of coastal cod (Gadus morhua L.) illustrated by tagging data and an individual-based growth and mortality model
(ICES CM Documents;1996/G:48, Working paper, 1996)Since 1983 more than one million reared cod juveniles have been tagged and released in different areas along the Norwegian coast. The goal of the programme is to evaluate the ecological and economical potential in sea ... -
Effect of Sub-Lethal Exposure to Ultraviolet Radiation on the Escape Performance of Atlantic Cod Larvae (Gadus morhua)
(Journal article; Peer reviewed, 2012-04-19)The amount of ultraviolet (UV) radiation reaching the earth’s surface has increased due to depletion of the ozone layer. Several studies have reported that UV radiation reduces survival of fish larvae. However, indirect ... -

Effects of continuous flow rate on development and mortality of halibut yolk sac larvae
(ICES CM Documents;1990/F:41, Working paper, 1990)Halibut (Hippoglossus hippoglossus L.) yolk sac larvae were raised in incubators with different rates of continuous flow. Most larvae died between Days 10 and 29 after hatching. Rate of mortality increased with increasing ... -
Effects of Cortisol on the Intestinal Mucosal Immune Response during Cohabitant Challenge with IPNV in Atlantic Salmon (Salmo salar)
(Journal article; Peer reviewed, 2014-05-08)Infectious pancreatic necrosis virus (IPNV) causes high incidence of disease in salmonids during the first period after SW transfer. During this period as well as during periods of stress, cortisol levels increase and ... -
