Tagging experiment results on cod in western Norway fjord areas
(ICES CM Documents;1986/G:80, Working paper, 1986)
During recent years, experiments with large scale release of artificially produced Q-group cod at locations in western Norway waters have been carried out with the aim ofincreaseing the cod catches. As the general ...
Using vessel acoustics to detect diving patterns of krill foraging predators automatically: development of a novel method for quantifying impact of krill fishing on seals and penguins
(;WG-EMM-15/25, Research report, 2015-06-20)
The aim of this work was to assess the possibilities of automatically generating a dataset of dive behaviour of air-breathing predators, based on acoustic data from a monitoring survey and from commercial krill fishing ...
Updating the Antarctic krill biomass estimates for CCAMLR Subareas 48.1 to 48.4 using available data
(;WG-EMM-15/28, Research report, 2015)
We present a novel index of Antarctic krill biomass in CCAMLR subareas 48.1 to 48.4, based on data from scientific nets and covering the years between 2000 and 2011. The annual biomass variation was significant (CV=73%) ...
Evaluation of Antarctic krill biomass and distribution off the South Orkney Islands 2011-2015
(;WG-EMM-15/54, Research report, 2015-06-22)
Annual acoustic trawl surveys for krill monitoring have been carried out by the Institute of Marine research, Norway near the South Orkney Islands since 2011. The survey has been conducted early in the fishing season ...

Measuring the effect of changes in catchability on the variance of marine survey abundance indices
(ICES CM Documents;1992/D:9, Working paper, 1992)
The average catch per tow by a research vessel survey is often used as an index of abundance. An estimate of the variance of such indices that is based only on the between station variability in catch may underestimate ...
