Fifty-one biologists from three states united at Aravaipa Creek in late March and early April 2021 to remove nonnative Yellow Bullhead fish that threaten the survival of the native fish community. Removing these non-native fish will help protect native fish species and their habitats.

The aquatic invasive species team at the Lake Havasu Field Office gave a presentation to educate the public on preventing the spread of aquatic invasive species from BLM-managed lands along the lower Colorado River. In addition to educating the public on how to help stop the spread of aquatic invasive species, the team will soon begin offering watercraft decontaminations for boaters on the Parker Strip on the California side of the Colorado River.

An invasive marine invertebrate known as “marine vomit,” that can smother native species has been found within Whiting Harbor in Sitka. This non-native carpet sea squirt, Didemnum vexillum, (D. vex) is thought to be native to Japan. It was first detected in Whiting Harbor in 2010 as a result of a citizen-science-marine invasive species bioblitz. Tammy Davis, Alaska Department of Fish and Game (ADF&G), invasive species program lead, was concerned along with other stakeholders including local Sitkans and those who work in the marine invasive species world, about the discovery and potential growth and spread of D. vex in Whiting Harbor.
