RECENT STRIDES IN PROPAGATION AND CULTURE OF NATIVE FRESHWATER MUSSELS TO RESTORE DECLINING POPULATIONS
Freshwater mussels are highly endangered in North America; over the last 27 years efforts to improve their conservation have resulted in improvements in propagation and culture techniques. In 2004 there were 7 established freshwater mussel propagation facilities in the United States and Canada and today there are at least 25. This surge was driven by the listing of species at the state and federal level, publication of the National Strategy for the Conservation of Freshwater Mussels in 1998 (updated in 2016) and the implementation of a policy for controlled propagation by the USFWS and NMFS in 2000. Three freshwater mussel propagation and culture workshops have taken place since 2002, the USFWS hosts a yearly class and a manual of protocols for propagation of native mussels will be published this year. Refinement of techniques for holding host fish, producing juveniles without hosts, wild and laboratory grow out and novel marking methods have resulted in hundreds of thousands of cultured mussels being used for restoration of populations in rivers across the United States, Canada and Europe.
