|Western Washington wetland|
The Washington Department of Fish and Wildlife (WDFW) conducted mudminnow surveys in past years and created a database of inhabited sites. Our office is currently working with WDFW to revisit several of these sites to see if these fish are still present. Upon capture of a mudminnow, we remove a small part of the caudal fin for genetic analysis to help us determine the relative uniqueness of each Olympic mudminnow population. This is our first year working with this unique species and we plan to collect more data at additional sites in upcoming years.
