Variation in fish condition between Atlantic cod (Gadus morhua) stocks and implications for their management
(ICES CM documents, Working paper, 2000)A comparative analysis of the fish condition (Fulton’s K) of 11 cod stocks in the North Atlantic in relation to the temperature of their habitat and their reproductive potential is presented. It is shown that the cod ... -
Variation in growth rate and age at sexual maturity in Atlantic salmon
(ICES CM Documents;1976/E:40, Working paper, 1976) -
Variation in stomach temperature as indicator of meal size in harbour seal, Phoca vitulina
(ICES CM Documents;1995/N:12, Working paper, 1995)To understand the role of the marine mammals as components in foodwebs, it is important to know the composition frequency and size of their meals. Marine mammals have a core body temperature of about 37°C, and feed mainly ... -
Variations in physical properties of pelagic eggs in different populations - genetic aspects
(ICES CM Documents;1970/F:29, Working paper, 1970) -
Variations in the cascading Barents Sea bottom water into the Norwegian Sea
(ICES CM documents, Working paper, 2006)Based on observations variations of the bottom water in the Bear Island Channel and the faith of this water downstream in the Norwegian Sea is investigated in relation to the Atlantic Water flow into the Barents Sea. On ... -
Variations in the distribution of blue whiting in the Barents Sea: climatic influences or year class effects?
(ICES CM documents, Working paper, 2003)Blue whiting (Micromesistius poutassou) in the Barents Sea represent the north-eastern fringe of the distribution of the species in the Atlantic. Distribution and abundance of blue whiting in the Barents Sea have fluctuated ... -
Variations in the Norwegian coastal current off Arendal during 1975 and 1976
(ICES CM Documents;1977/C:36, Working paper, 1977)Comparison between mean monthly freshwater discharges to Skagerrak, surface salinity and computed geostrophical volume transport through two sections off Arendal indicates a connection between variations in freshwater ... -
Variations in the Production Capacity of the Norwegian Sea during 1954, 1958 and 1959
(ICES CM Documents;1961/123, Working paper, 1961) -
Verified acoustic identification of Atlantic mackerel
(ICES CM documents, Working paper, 2004)Calibrated, digitised data from simultaneously working multi-frequency echo sounders with nearly identical and overlapping acoustic beams have been used to generate new, synthetic echograms where only targets identified ... -
Vertical distribution (0–1000 m) of gelatinous zooplankton and particulate matter (60ìm<<5mm) along the Mid Atlantic ridge in the North Atlantic. Potential impact of appendicularians on particle aggregation
(ICES CM documents;2007/F:04, Working paper, 2007) -
Vertical distribution and feeding of cod larvae in relation to occurrence and size of prey organisms
(ICES CM Documents;1977/L:33, Working paper, 1977) -
Vertical distribution and population structure of copepods along the northern Mid-Atlantic Ridge
(ICES CM documents;2007/F:07, Working paper, 2007)The Mid-Atlantic Ridge (MAR) between 40°N (Azores) and 63°N (Iceland) is the largest topographic feature in the North Atlantic Ocean. Despite generally limited surface production, there is evidence that the mid-ocean ridges ... -
Vertical distribution of cod, haddock and redfish; Impact on bottom trawl and acoustic surveys in the Barents Sea
(ICES CM Documents;1997/Y:16, Working paper, 1997)At a selected location in the Barents Sea acoustic observations, bottom- and pelagic trawl catch data were collected over a 10 day period. A large proportion of the fish were in the acoustic dead zone during the sampling ... -
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 ... -
Vertical entrance into a trawl of Barents Sea gadoids as studied with a two level fish trawl
(ICES CM Documents;1985/B:46, Working paper, 1985)Catch figures of different demersal species(cod, haddock, saithe etc.) in the cod-ends of a two level trawl were examined using variable height of the separating panel (0.5, 0.75, 1.0 and 1.5 m). Cod enters the trawl ... -
Vessel heave, and index for air bubble attenuation corrections
(ICES CM Documents;1991/B:37, Working paper, 1991)The possible use of vessel heave as a correction indicator for air bubble attenuation of acoustic signals from hull mounted transducers is investigated. Vessel heave was monitored along with the echo energy from the air ... -
Viral haemorrhagic septicaemia in Norway—possible interactions between farmed and wild fish
(ICES CM documents;2010/J:09, Working paper, 2010) -
Vital population rates across multiple spatial scales: A geostatistical analysis
(ICES CM documents;2005/L:01, Working paper, 2005)Population and community level processes change across multiple spatial scales. Understanding these patterns and the factors that drive them are essential for the development of spatial approaches in fisheries management. ... -
Voice controlled form filling
(ICES CM Documents;1991/C:22, Working paper, 1991)During field work in the sea - in particular when collecting data like weight, length, sex, stadium, etc. from fish samples, the observations are first manually noted in a standardized sampling form. One popular form ... -
Vulnerability to predation of small cod (Gadus morhua) that escape from a trawl
(ICES CM Documents;1995/B:15, Working paper, 1995)Studies of the vulnerability to gear damage of fish that have been caught in a trawl but have escaped through the codend meshes have focussed on determining survival rates. This study examines the risk of predation in ...
