Quarter 1 International Bottom Trawl Survey (IBTS Q1). RV “GO Sars”, 23 January – 22 February 2013

Abstract

The IBTS quarter 1 multispecies bottom trawl survey, coordinated by the ICES IBTSWG, involves 7 countries and covers the North Sea and Skagerrak. The Norwegian part of this survey included bottom trawling in water < 200 m to contribute data for trawl indices of several species and MIK tows from water < 200 m to provide an index of herring and sprat larvae. Also completed were the Utsira W hydrographic transect and MIK-M sampling for fish eggs and gadoid larvae (along the transect and north of 48°). Guests included seabird observers from JNC, UK and a student from UiB conducting gadoid egg incubation experiments.
