Native Unionid Mussel and Zebra Mussel Distribution in Crane Creek Wetland at ONWR

Unionid mussel populations have declined in the because of the   effects of impoundments, commercial exploitation, pollution, and   situation. Non-native species such as zebra mussels have also caused   drastic declines in these populations because they both filter feed   on diatoms and detritus, with zebra mussels out-competing unionids   for food. Because unionid numbers in the Great Lakes are declining,   it is important to determine the characteristics of their habitats   for the preservation and management of these animals. This project   developed a taxa list and life history of unionid mussels at the   Crane Creek Wetland and distribution information on the zebra   mussels. The study also gathered data needed to produce G.I.S. maps   of habitat characteristics and unionid distributions in the wetland.   This information will help develop a model to manage other wetlands   along Lake Erie and work towards restoring populations of rare and   endangered species. The study also revealed that zebra mussels die   off after attaching to unionids that burrow into soft mud and that   sediment depth might affect their interactions.
