Potential impacts of bottom trawling on benthic communities in Prydz Bay, Antarctica
1. Catches of fish only exceeded 50 kg at two stations near the shelf break (stations ... G and H). The remaining catches of fish were mostly less than 20 kg. Catches in the centre of the bay (stations ... for finfish are designed to minimise the catch of benthos. Nonetheless, bottom trawling in Prydz Bay ... . Each graph shows the catch from stations marked with corresponding letters. Station coordinates ...
