Discovery of Sabellaria spinulosa reefs in an intensively fished area of the Dutch Continental Shelf, North Sea

Abstract The tube-building polychaete Sabellaria spinulosa (Ross worm) can form conspicuous biogenic reefs that stabilize the seabed and increase biodiversity by providing a habitat for a multitude of other species. These reefs, however, are assumed to be vulnerable to human-induced physical disturbances of the seabed. In the Greater North Sea, S. spinulosa reefs are recognized to be under threat … Read more

Building a GFCM framework to combat IUU fishing

Monitor, control and surveillance are crucial to ensure proper fisheries management and to rebuild stocks, in particular in the Mediterranean Sea, where 80% of the stocks are considered to be outside biologically safe limits. The General Fisheries Commission for the Mediterranean (GFCM) has taken significant steps in the last years towards reversing this situation, including … Read more
