Wildlife biologists mix electricity and water to catch fish in Arkansas River

Posted: Updated:
PUEBLO COUNTY -

Biologists from the Colorado Parks and Wildlife Department are working to find out just how many fish are in the Arkansas River.

Crews of biologists started catching fish in the river below the Lake Pueblo Dam Monday, but they used special equipment instead of a rod and reel.

To make sure they don't miss any fish, an electrode is dropped into the water, which temporarily disables the fish, causing them to float to the surface. The biologists then scoop the fish with nets and mark them as counted.

"(It) allows us to figure out how many trout we have in this stretch of river, which helps us determine if our regulations are working properly and how many fish we need to stock if we need to bump up our stock," said Aquatic Biologist Carrie Tucker.

The process will take about a month for biologists to establish a final count.
