People dumped their pets into lakes, officials say. Now football-size goldfish are taking over.

Read the full story in the Washington Post.

The invasion begins innocently enough: A goldfish paddles the secluded waters of an at-home aquarium, minding its own business, disturbing no native habitats.

The real trouble comes later, when the human who put it there decides it’s time for a change. Not wanting to hurt the fish, but not wanting to keep it either, the pet’s owner decides to release it into a local lake, pond or waterway. That decision, experts say, is well-meaning but misguided — and potentially harmful.

Officials in Burnsville, a city about 15 miles south of Minneapolis, demonstrated why late last week, when they shared photographs of several massive goldfish that were recovered from a local lake. The discarded pets can swell and wreak havoc, the city warned.

UC launches WeedCUT, a new online tool to manage invasive weeds in wildlands without herbicides

Read the full story from the University of California.

California has abundant wildlands — forests, rangeland, open areas, wildlife refuges and national, state, and local parks — that need protection from invasive plants. Invasive plants affect all Californians by increasing wildfire potential; reducing water resources; accelerating erosion and flooding; threatening wildlife; degrading range, crop and timberland; and diminishing outdoor recreation opportunities. According to the California Invasive Plant Council (Cal-IPC), more than 200 identified plant species harm California’s wildlands.

Cal-IPC and the University of California Statewide Integrated Pest Management Program (UC IPM), with funding from the California Department of Pesticide Regulation (DPR) Alliance Grants Program, developed two resources that provide land managers access to the latest information on non-herbicide practices for managing weeds in wildlands. Best Management Practices for Non-Chemical Weed Control is a free downloadable manual. The same information has been incorporated into an interactive online tool called WeedCUT (Weed Control User Tool:

The company behind the viral fish tube — or salmon cannon — has a new project: Keeping Asian carp out of Lake Michigan using facial recognition technology

Read the full story in the Chicago Tribune.

There may come a day on the Illinois River when a fish swims up a chute, slides through a scanner, and, after being recognized as a feared silver carp, is sorted and removed, eventually ending up in a carp burger on your dinner plate.

Keeping invasive carp out of the Great Lakes has involved a series of less-than-silver bullets — from commercial fishing to carbon dioxide experiments to the forthcoming Brandon Road barriers near Joliet from the U.S. Army Corps of Engineers.

Now, fish recognition is entering the fray.

When an invasive species overruns a new ecosystem, it is often assumed that the invader recently arrived at its new home and rapidly took over. But a new report in the journal BioScience finds that many new arrivals aren’t nearly as impatient as this narrative implies.
