| Objectives | Survey WH 458 covered fisheries research representing the German contribution to the International Bottom Trawl Survey (IBTS) in quarter 3, and was planned to be one component of the two-ship operation in the German Small-scale Bottom Trawl Survey (GSBTS). Both surveys use the same principal fishing methods but at different spatial scales, applying a GOV otter board trawl (Grande Ouverture Verticale). All fishing hauls were accompanied by hydrographic measurements and investigations of benthic epifauna, infauna and sediments. Bycatch of marine litter in the GOV is reported.
In order to fully cover the international IBTS programme, the GSBTS component of the survey had to be cancelled due to time constraints. The survey started on 20 July 2022 in Bremerhaven, two days later than planned, starting with the IBTS on 21 July. Due to Covid-19 infections, Walther Herwig III returned to Bremerhaven on 23 July. The survey continued on 06 August and the remaining program was successfully completed on 15 August. The ‘Walther Herwig III’ returned to Bremerhaven on 16 August 2022. |
