Follow-up fishery survey in the Hywind Tampen offshore wind power field during construction and early operation

Abstract

The aim of the cruise was to follow up the pre-construction studies in Hywind Tampen in 2022. In march 2023, when this cruise was carried out, seven of the eleven planned turbines were in operation. As in 2022, the experiments were based on a gradient fish capture study using bottom gillnets at pre-determined stations. The catches were sampled and analysed to obtain information about species richness, abundance, maturity stage, sex, condition and diet and how these vary with distance to the windfarm. In addition, acoustic data were collected.
