Consequently, the species is now strictly protected under both UK and European legislation. %PDF-1.5 Participants will learn an overall system for identifying mussels and characteristics of major taxonomic groups within the families Unionidae and Margaritiferidae and In the United States and Canada, areas home to the most diverse freshwater mussel fauna in the world, there are 297 known freshwater mussel taxa. This is a much bigger mussel than the European species, reaching 20 cms before harvesting. Checklists containing Freshwater Pea Mussel. Checklists containing Freshwater Pearl Mussel. %%EOF 609 0 obj <>stream Both species are now listed as Size: Up to 51 mm Habitat: Able to live where any hard substrates (ex: rocks, pipes) exist on which they can attach.

Freshwater pearl mussels have a fascinating lifecycle, of which part is spent attached to the gills of young salmon and brown trout. The UK is home to 6 species of freshwater mussel of which two, the depressed river mussel (Pseudanodonta complanata) and the pearl mussel (Margaritifera margaritifera), have experienced significant declines during the 20th century. �ѐL*+���^�J3�[26h8���F9�8�� ��F�?�&xf���ivq�)�ɼ����^W��>w+��&;~��/�f��u�e/E���=�ṅ��r�c�� �A�?�o���)ќm�y�y�iھ�$���ۛ�����h�����۲�zS�e�3|9h������h�/G�i�6����»�FHq`T�f}{=�_mY��d��W=��iU�ux����eϛv]��H������3�L$�I7����lr����3�f���IY-��I9�=�蜭�eǔ�Κ�?

This aquatic bivalve mollusc is a large species of freshwater mussel. Adult mussels have a robust, brown-black shell of elongate elliptical shape with a concave ventral margin. Freshwater pearl mussels live in clean, fast-flowing rivers across northern England, Shropshire and Devon. The latter is associated with fast flowing water with low calcium content.
