Ziel der Reise / Objectives of Cruise:
The IBTS is designed to acquire recruitment indices and tuning data for several finfish species. The recruitment indices are used in ICES assessment working groups (herring, North Sea demersal fish, mackerel) and ACFM. Data on spatial and temporal distribution of fish species are used for ecosystem studies. Also Ichthyoplankton and Hydrography data are collected.
