| dc.description.abstract | Stratified trawl surveys have been carried out in the Barents
Sea and the Svalbard areas since 1981. Based on the assumption
of a constant area swept by the trawl during a standard trawl
haul at any depth, swept area abundance indices have been
presented for both areas. The results have been used in the
management of the Arcto-Norwegian cod stock.
In this paper results from measurements of trawl geometry
during trawling operation during a standard stratified trawl
survey in the Svalbard area in September-October 1985 are
presented and the implication on the trawl indices of these
results are discussed. | no_NO |
