Egg mortality in recruit- and repeat-spawning cod: an experimental study
(ICES CM documents, Working paper, 1995)Experiments on the reproduction of individual Norwegian coastal cod and for the Arcto-Norwegian cod were conducted during the years 1982-92, and the year 1995 respectively. The experimental fish used were held in captivity ... -
The egg production of Arcto-Norwegian cod (Gadus morhua L.) in the Lofoten area estimated by egg surveys
(PINRO-IMR Symposium, Conference object, 1984)Spawning intensity measurements have been executed in Lofoten each year since 1976. They consist of egg net samples at selected spawning cites . In 1983, in addition, four quasi-synoptic egg surveys were conducted during ... -
Egner vintertoktet seg til overvåking av endringer i fiskesamfunnet i Barentshavet? : en gjennomgang av metodikk og data fra 1981-2007
(Fisken og havet, Research report, 2009-12-10)The winter survey (1981-) is the longest bottom trawl time series in the Barents Sea. The survey is used as tuning series in cod and haddock assessment, but change and ecosystem-based management, necessitates the study of ... -

Electrophoretic studies of redfish (Genus sebastes) from Icelandic and Greenland waters
(ICES CM Documents;1992/G:36, Working paper, 1992)Sebastes spp. from Icelandic and Greenland waters were analysed for biochemical genetic variation by agar gel and starch gel electrophoresis. The main emphasize was put on S. marinus, but the oceanic type S. mentella ... -

Enhancing stock-recruitment models for North Sea cod by including climate and zooplankton
(ICES CM documents;2009/C:08, Working paper, 2009)The “recruitment problem” - trying to understand what regulates recruitment variability in marine fish populations - has been the number one issue in fisheries science since the early twentieth century. Intuitively, the ... -

Environmental effects of marine Norwegian fish farms
(ICES CM Documents;1985/F:37, Working paper, 1985)Sedimentation rates under fish farms may be very high, and high levels of fish stock may lead to harmful accumulation rates of the nutrient salt ammonia. The environmental effects of the organic load range from minor ... -
Environmental effects on ocean entry of Atlantic salmon (Salmo salar) smolt across its range of distribution

Environmental toxicology: Population modeling of cod larvae shows high sensitivity to loss of zooplankton prey
(Journal article; Peer reviewed, 2010-12-30)Two factors determine whether pollution is likely to affect a population indirectly through loss of prey: firstly, the sensitivity of the prey to the pollutants, and secondly, the sensitivity of the predator population to ... -

Equivalent beam angles for several standard transducers
(ICES CM documents, Working paper, 1990)Nominal values for the equivalent beam angle are given for several transducers. These are the standard split-beam transducers designed for the SIMRAD EK500 scientific echo sounder, with operating frequencies of 38 and 120 ... -
Erfaringer etter oljeutslipp langs kysten av Norge
(Rapport fra Havforskningen;Nr. 23 - 2012, Working paper, 2012-07)Environmental studies were carried out after each of the four largest oil spills from vessels in Norwegian coastal waters: ”Rocknes” in 2004, ”Server” in 2007, ”Full City” in 2009 and ”Godafoss” in 2011. The amount of ... -
Establishment of new wintering areas in herring co-occur with peaks in recruit to spawner ratio
(ICES CM documents;2009/H:11, Working paper, 2009)During late summer, Norwegian spring-spawning herring migrate to wintering areas, where they remain for about five months in dense aggregations. First-time spawning cohorts typically adopt the overwintering area of the ... -
Esterase variation in herring studied by isoelectric focusing
(ICES CM Documents;1997/AA:1, Working paper, 1997)Few suitable genetic characteristics for studying herring population structure are available, and the main aim of the study reported here has been to reveal traits which display useful genetic variations for application ... -
Estimated hatching date and growth history of Norwegian spring spawning herring (Clupea harengus L.) from otolith data of larvae of the 1990 yearclass
(ICES CM Documents;1991/H:14, Working paper, 1991)This study was performed on herring larvae of the 1990 yearclass of Norwegian spring spawners. The larvae were caught in May on the Norwegian shelf in the area from 64 °N - 69 °N. There was one size group of larvae with ...
