Species Studied

Amur Goby (Rhinogobius brunneus)

The Amur goby Rhinogobius brunneus is a small fish native to the far east regions of Asia. The Amur goby was discovered in the Columbia River Basin in 2004, with the first record occurring in the East Fork Lewis River in western Washington State. Since then other specimens have been collected from the Columbia River at Crims Island, from the Ramsey Wetland in Portland, Oregon, and the Sandy River near Troutdale, Oregon, suggesting that there may be established and potentially reproducing populations in tributaries to the Columbia River. However, little is known of the specific characteristics of this recently introduced fish species. For instance, some species in the Rhinogobius brunneus species complex are amphidromous, spending portions of their lives in both fresh and saline waters while other species do not migrate to salt water; which of these species has been introduced into the Columbia River Basin is not currently known.
