A preliminary report on the natural occurrence and ecology of Atlantic halibut (Hippoglossus hippoglossus) postlarvae and young immature stages
Haug, Tore; Sundby, Svein (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 ... -
Abundance indices for the Arcto-Norwegian cod for the period 1979 -1986 based on investigations in June/July
Bjørke, Herman; Sundby, Svein (ICES CM Documents;1986/G:75, Working paper, 1986)Postlarvae Surveys have been carried out in the western part of the Barents Sea in June/July since 1977. The aim of the investigations has been to study the distribution pattern of fish larvae and their relation to the ... -
Bio-physical properties of Norwegian coastal cod eggs
Jung, Kyung-Mi; Sundby, Svein; Thorsen, Anders; Folkvord, Arild; Kjesbu, Olav Sigurd (ICES CM documents;2009/C:11, Working paper, 2009)Vertical distribution of fish eggs and larvae is a key factor for transport and retention of the offspring, and for problems linked to mixing/separation between populations, and hence for mechanism maintaining genetic ... -
An ecosystem modeling approach to predicting cod recruitment
Svendsen, Einar; Skogen, Morten D.; Budgell, W. Paul; Huse, Geir; Stiansen, Jan Erik; Ådlandsvik, Bjørn; Vikebø, Frode; Asplin, Lars; Sundby, Svein (ICES CM documents, Working paper, 2006)Abstract The NORWECOM ocean model system implemented with the ROMS ocean circulation model has been run to simulate conditions over the last 25 years for the North Atlantic. Modelled time series of volume fluxes, primary ... -
Effects of climate on marine ecosystem
Vikebø, Frode; Sundby, Svein; Ådlandsvik, Bjørn (ICES CM Documents;2003/O:7, Working paper, 2003)The spawning areas of the Arcto-Norwegian cod are located along the coast of mid and northern Norway, particulary in the Lofoten where up to 70% of the spawning occurs from mid March to early May. The larvae are carried ... -
Feeding and vertical distribution of cod larvae in relation to availability of prey organisms
Ellertsen, Bjørnar; Solemdal, Per; Sundby, Svein; Tilseth, Snorre; Westgård, Trond; Øiestad, Victor (Conference object, 1979)The year-class strength of the Arcto-Norwegian cod stock varies on an annual basis by a factor of about 20:1 and is determined at the 0-group stage (about 1/2 year old cod). Since the number of eggs spawned far exceeds the ... -
Feeding conditions of north-east Arctic (Arcto-Norwegian) cod larvae compared to the Rothschild-Osborn theory on small-scale turbulence and plankton contact rates
Sundby, Svein; Fossum, Petter (ICES CM Documents;1989/G:19, Working paper, 1989)Data on first feeding North-east arctic cod larvae in Lofoten, sampled during the period 1976 - 1984, are examined to verify the theory on the influence of microturbulence on the contact rate between predator and prey ... -
In/out-flow of coastal water in Vestfjorden
Sundby, Svein (ICES CM Documents;1978/C:51, Working paper, 1978)Hydrographic sections in Vestfjorden, Northern Norway, during winter 1977 showed strong horizontal temperature gradients on the west side of the fjord indicating an outflow of cold coastal water. Analysis of sea thermograph ... -
Marine ecosystems and fish stocks under climate variability and change
Sundby, Svein (ICES CM Documents;, Working paper, 2006) -
Mechanisms a ecting the transport of early stages of Norwegian Coastal Cod - a fjord study
Myksvoll, Mari Skuggedal; Sundby, Svein; Ådlandsvik, Bjørn; Vikebø, Frode (ICES CM documents;2008/L:16, Working paper, 2008)An increasing concern in sheries management in Norway is how the Arcto-Norwegian Cod (ANC), with its feeding habitat in the Barents Sea, is separated from or mixed with the local populations of Norwegian Coastal Cod ... -
On the mechanisms behind salinity anomaly signals of the northern North Atlantic
Sundby, Svein (ICES CM documents, Working paper, 2001) -
Swell as a turbulence source in shallow water
Stiansen, Jan Erik; Sundby, Svein; Jenkins, Alastair D.; Nilsen, Jan Even Øie (ICES CM documents, Working paper, 2005)Two field investigations in an exposed shallow area outside Lofoten, western Norway, were conducted in 1995 and 1996. Direct measurements of turbulence were conducted from an underwater tower with acoustic current meters ... -
Vertical distribution of pelagic fish eggs in relation to species, spawning behaviour and wind conditions
Solemdal, Per; Sundby, Svein (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 ...
