This is of particular concern in the Baltic Sea where a survey carried out in 1995 indicated that the population is low and current levels of anthropogenic mortality are believed to be unsustainable. notPlanned Anna Moscrop Marine Conservation Research Ltd Primary contact amoscrop@mcr-team.co.uk NA NA NA Anna Moscrop owner NA zd_344 2025-07-31T14:13:48-04:00 dataset Moscrop, A. 2011.
