|In Friday Ocean Findings Week 6 we are featuring 2 species on OSPAR's list of threatened and/or declining species and habitats that are also listed as Critically Endangered by the IUCN.
While there have been positive signs in parts of the North Sea and Celtic Seas in terms of increasing catch rates as indicative measures of improvement, the common skate complex are still infrequently recorded or absent from some former parts of their geographic range. Both species of the common skate complex are on the prohibited species list according to EU fishing regulations.
The status of European sturgeon is still highly critical in the North-East Atlantic, however a notable increase in abundance in the North Sea, Celtic Seas and Bay of Biscay and Iberian Coast due to restocking programmes in the Gironde and the Elbe river systems have been observed. Threats from habitat alteration, bycatch and increased abundance of alien sturgeon species still pose a significant threat to this species although OSPAR countries are taking national measures.
We hope you enjoy these reports. Please do contact us with any comments at [email protected]
