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 ... -
Acoustic abundance estimates of the Icelandic stock of capelin, October 1978 - January 1980.
(ICES CM Documents;1980/H:63, Working paper, 1980)During the period October 1978 - January 1980 several estimates of the size and yearclass composition of the Icelandic capelin stock were obtained by the acoustic method. Surveying was carried out in October 1978, ... -
