Report on surveys of the distribution, abundance and migrations of the Norwegian spring-spawning herring, other pelagic fish and the environment of the Norwegian Sea and adjacent waters in late winter, spring and summer of 1997
(ICES CM Documents;1997/Y:4, Working paper, 1997)The distribution and migrations of Norwegian spring spawning herring in the Norwegian Sea in the spring and summer of 1997 were mapped during 11 coordinated surveys carried out by Faroese, Icelandic, Norwegian, Russian ... -
Report on surveys of the distribution, abundance and migrations of the Norwegian spring-spawning herring, other pelagic fish and the environment of the Norwegian Sea and adjacent waters in late winter, spring and summer of 1999
(ICES CM Documents;1999/D:3, Working paper, 1999)Introduction: The Norwegian spring-spawning herring reoccupied the Norwegian Sea as its main feeding area in the early 1990s, after nearly 25 years of absence. The herring stock is now a typical straddling and highly ... -
Return of Norwegian spring spawning herring (Clupea harengus L.) to historical spawning grounds off southwestern Norway
(ICES CM Documents;1991/H:24, Working paper, 1991)From the mid-1940s to mid-1960s a northward displacement of the spawning areas of the Norwegian Spring Spawning Herring was observed. Further retraction of the population from traditional feeding and spawning grounds ... -
Satellite observations and forecasting can mitigate effects of toxic algae blooms
(Working paper, 2000) -
Seasonal distribution and abundance of killer whales around Lofoten and Vesterålen Islands, northern Norway
(ICES CM Documents;1992/N:11, Working paper, 1992)Killer whales (Orcinus orca) have been pohotoidentified around Lofoten and Vesterålen islands northern Norway during fall-winter (October-February) and summer (June-August) in 1990 and 1991. Some background data exists ... -
Spatial distributions of variables in marine environmental and fisheries research. Part 1: Geostatistics and autocorrelated environmental and fisheries data
(ICES CM Documents;1996/D:16, Working paper, 1996)The geographical information very often is lost during calculation of indices for the abundance from surveys. Isoplet diagrams showing the distribution of both fish abundance and temperature/salinity are usually produced ... -
Studying the relationship between spatial fish distributions and trawl catches
(ICES CM Documents;2004/R:26, Working paper, 2004)We propose an approach for studying the relationship between spatial fish distributions and the distribution of numbers in trawl catches. Individual spatial fish distributions are derived from acoustics data collected with ... -
The buoyancy of sprat (Sprattus sprattus) eggs and larvae in the Skagerrak area
(ICES CM Documents;1985/L:6, Working paper, 1985)Buoyancy of sprat eggs and larvae was determined with a linear density gradient. There were four experimental groups of eggs, three caught at sea and one from spawning in the laboratory. The neutral buoyancy of the sprat ... -
The CoML pilot project MAR-ECO: Goals, status, and significance for ICES
(ICES CM Documents;2002/L:10, Working paper, 2002)The Mid-Atlantic ridge and adjacent waters are targeted in an international ecosystem study under the Census of Marine Life programme. This pilot project shall gather new knowledge on biodiversity, distribution patterns, ... -
The predation of cod on capelin 1983 -1988
(ICES CM Documents;1988/G:55, Working paper, 1988) -
The relation between the spatial distribution of early juvenile cod (Gadus morhua L.) and zooplankton biomass in the Barents Sea
(ICES CM Documents;1997/T:32, Working paper, 1997)The year class strength of Arcto-Norwegian cod (Gadus morhua L.) in the Barents Sea is extremely variable. One of the key indicators for a possible strong year class is water temperature since good year classes may be ... -
The relationship between the location of western mackerel spawning, larval drift and recruit distributions: A modelling study
(ICES CM Documents;1996/S:33, Working paper, 1996)Summary: Mackerel spawning distributions have changed over the last 20 years. From 1977-1995 there has been a progressive westerly shift in the distribution of spawning in May/June (peak spawning), with a resultant ... -
The spawning and distribution of mackerel eggs in the North Sea related to the hydrography
(ICES CM Documents;1985/H:37, Working paper, 1985)The distribution of mackerel eggs in the North Sea have been studied several years to estimate the spawning stock size. During these surveys the hydrographical regime has been mapped. Spawning intensity and hydrographical ... -
Trophic ecology of deepwater fishes associated with the continental slope of the eastern Norwegian Sea
(ICES CM Documents;1998/O:51, Working paper, 1998)In June 1995 and 1996 demersal fishes on the continental slope of the eastem Norwegian Sea were sampled to study distribution patterns and community structure. The diets of the more abundant slope species were characterised ... -
Variability of the drift patterns of spring spawned herring larvae and the transport of water along the Norwegian shelf
(ICES CM Documents;1995/Q:25, Working paper, 1995)Summary: A 3-dimensional baroclinic hydrodynamic model implemented for the North Sea, the Norwegian coast and part of the Norwegian and Barents Seas has been run for 18 years. This model has been used to study the Norwegian ... -
Vertical distribution of pelagic fish eggs in relation to species, spawning behaviour and wind conditions
(ICES CM Documents;1981/G:77, Working paper, 1981)1. The mean reduction of egg diameter from March to April is from 1.45 to 1.39 mm and 1.44 to 1.38 mm for artificially and naturally spawned eggs of Arcto-Norwegian cod, respectively. This means a reduction of volume of ... -
