ObjectivesThe cruise should survey the winter bottom fish assemblages in the German Bight and the abundance and distribution of fish larvae in the Southern North Sea. The German Small-scale Bottom Trawl Survey (GSBTS) continued the long-term investigation of winter bottom fish assemblages through sampling of the standard area "Box A" in the German Bight. The mean catch yielded is lower compared to 2013, but in the same order of magnitude as the period 2007-2011. Within the 10-by-10 nautical mile area in the Box, the GOV bottom trawls were accompanied by monitoring of the benthic epifauna with a 2-m beam trawl. Compared to preceding years, the epifauna in Box A was dominated by high numbers of the shrimp Crangon crangon, the bivalve Nucula nitidosa and the starfish Asterias rubens, while the goby Pomatoschistus minutus and the shrimp Crangon allmanni were less abundant The international herring larvae surveys in the North Sea (IHLS) are conducted annually during the autumn and winter herring spawning activity and monitor the spatial distribution and abundance of herring larvae. Unfortunately, the storm "Elon", "Felix", "Gunther" and following depressions prevented any sampling activity on herring larvae in the area under investigation. Consequently, no larvae abundance index can be calculated for the Southern North in the first half of January this year.
