Acoustic abundance estimate of 0-group north-east Arctic cod and haddock
(ICES CM Documents;1997/BB:15, Working paper, 1997)The abundance of the 1991-1994-year classes of north-east Arctic cod and haddock at the age of six month have been estimated on the basis of Norwegian acoustic data from the International 0-group fish survey in the Barents ... -
Biological reference points for north-east Arctic cod and haddock
(ICES CM Documents;1989/G:29, Working paper, 1989)It has been suggested by ACFM that Fmed might be preferable to Fmax as a biological reference point for the North-East Arctic cod. However, the Fmed level of more than twice Fmax appeared high, and it was known to have ... -
Diurnal variation in frequency response of gadoids in the Barents Sea
(ICES CM documents, Working paper, 2006)Earlier studies have demonstrated substantial diurnal variation in acoustic abundance of fish. Both the level and the uncertainty of abundance estimates from surveys carried out around the clock are affected. It has been ... -
Haddock avoidance reactions during trawling
(ICES CM Documents;1986/B:36, Working paper, 1986)Fish reaction to the whole trawling operation was studied using a stationary echo sounder-system observing the fish in front of the vessel and during trawl passage. Strong avoidance reactions were observed on haddock, ... -
Initial results from the 2004 ichthyoplankton survey of the North Sea
(ICES CM documents;2005/AA:04, Working paper, 2005)In 2004 an international consortium comprising England, Scotland, Netherlands, Germany, Denmark and Norway conducted an ichthyoplankton survey covering the whole of the North Sea in order to comprehensively survey cod ... -
Limiting inter-annual variation in total allowable catch strategies. An application to ICES roundfish stocks
(ICES CM Documents;2003/X:7, Working paper, 2003)This study evaluated through simulation management strategy that stabilise catch levels by setting bounds on the inter-annual variability in Total Allowable Catches (TACs). An integrated modelling approach was used, which ... -
Maturation in North-East-Arctic Haddock.
(ICES CM documents, Working paper, 1999)Maturation in north-east-arctic haddock was studied in relation to fish age; length, weight and condition factor using data from scientific surveys in 1989-1998. In order to investigate the reliability of the maturity ... -
Modelling the sources of mortality for larval haddock on Georges Bank and their effects on behavior
(ICES CM documents;2009/T:08, Working paper, 2009)Fish larvae have the ability to change their vertical position in the water column and thusly cannot be treated as passive particles in coupled biological-physical individualbased models (IBMs). The vertical variability ... -
Mortality and injuries of haddock (Melanogrammus aeglefinus) that are caught by pelagic longline
(ICES CM documents, Working paper, 2002)By-catches of haddock (Melanogrammus aeglefinus) below legal size (44 cm total length) in the seasonal pelagic longline fisheries for haddock off the coast of Finnmark, northern Norway, are often high. The small fish are ... -
Mortality and injuries of haddock, cod and saithe escaping through codend meshes and sorting grids
(ICES CM documents, Working paper, 2002)Mortalities and injuries of the gadoids haddock (Melanogrammus aeglefinus L.), cod (Gadus morhua L.) and saithe (Pollachius virens L.) were studied after codend and grid escapement in two full scale trials in 2000 and 2001 ... -

Norwegian investigations on young cod and haddock in the Barents Sea during the winter 1982
(ICES CM documents, Working paper, 1982)An acoustic survey and a bottom trawl survey were carried out in the Barents Sea during winter 1982. Both surveys showed that there has been a reduction in the total number of cod of about 50% and about 75% for haddock in ... -
