The effect of biological and physical factors on the survival of Arcto-Norwegian cod and the influence on recruitment variability
(PINRO-IMR Symposium, Conference object, 1987)Data from egg and larval field investigations h the Lofoten area are used together with long time series of data on temperature and zooplankton in Lofoten and abundance indices of Arcto-Norwegian cod. The importance ... -
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 ... -

Effect of turbulence and different types of fertilizers on phytoplankton and oyster larvae (Ostrea edulis) in mesocosms
(ICES CM Documents;1986/K:41, Working paper, 1986)Different types of inorganic fertilizers were added to five cubic metres plastic bags. Different turbulent regimes were established in the bags. The effects of these manipulations on nutrient salts, chlorophyll a, ... -
The effects of a minimum landings size regulation in the fishery of Norwegian spring-spawning herring
(ICES CM Documents;1986/H:51, Working paper, 1986)Effects of minimum landing size (LC) in the fishery of Norwegian spring-spawning herring have been investigated. The herring is assumed to be a unit stock, in which the growth of immatures differs according to the ... -

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 different rearing environments on the mortality of Atlantic salmon broodstock and eggs
(ICES CM Documents;1984/F:26, Working paper, 1984)Atlantic salmon (Salmo salar) reared for three years in seawater were moved to brackish- and freshwater before they matured. A control group matured in seawater. The groups were given different feeding regimes the last ... -
Effects of Fishing Tourism in a Coastal Municipality: a Case Study from Risør, Norway

Effects of light on the development, activity and mortality of halibut (Hippoglossus hippoglossus L.) yolk sac larvae
(ICES CM Documents;1990/F:43, Working paper, 1990)Halibut yolk sac larvae were kept at different light intensities from Day 1 posthatch. Measurements of activity and swimming speed showed that larvae that were kept in darkness were more active, but had lower swimming ... -
