Two different anglers on two different waterbodies, but both in the anadromous zone of the Columbia River basin and both on the same day – July 17, 2017 – say they saw one of the most feared invasive predators in the basin, a northern pike. But, their alleged sightings were quickly debunked … by science.
As inspection stations that search arriving watercraft for aquatic invasive species – especially quagga and zebra mussels – begin to close, the State of Montana reported that it had completed 110,000 watercraft inspections in 2019.
The Grant, Chelan and Douglas Public Utility Districts are contributing to an effort by tribes and state agencies to control Northern Pike, a voracious predator that, if not contained, could set back decades of salmon recovery efforts across the Pacific Northwest.
A letter in support of a U.S. Army Corps of Engineers’ rapid response plan for invasive mussels got a thumbs up from the Northwest Power and Conservation Council.
An invasion of quagga and zebra mussels is being held off at the borders of Northwest states through the efforts of invasive species inspection stations, but the U.S. Army Corps of Engineers’ Walla Walla District is preparing for the worst.
In a state that lies in the upper headwaters of the Columbia River basin and considers itself guardians in keeping zebra and quagga mussels out of the basin, Montana says that more can be done and calls on the Bonneville Power Administration to help fund permanent watercraft inspection stations.
Nearly 18,000 river kilometers (11,185 miles) of Columbia River basin streams currently has suitable habitat for an invasive predatory fish that, as climate warms, is a range that is predicted to increase by 10,000 river miles by 2080, according to a recent study.
Beginning in 2022, fish farms will no longer be allowed to raise non-native fish in Washington’s waters. Until then, updated permits from the Washington Department of Ecology require Atlantic salmon farms to step up their monitoring, inspections and reporting, and to have emergency response plans, the agency said Thursday.
The Western Governors Association at its annual meeting last week approved a resolution calling for the creation of a new Western Invasive Species Council; new mechanisms to enhance regional invasive species research, planning and coordination; and recommendations to Congress and federal agencies on improving invasive species management on federal lands and supporting state-led management efforts.
