GRAND CANYON NP, AZ (Tucson News Now) -

Wildlife workers are watching nine endangered razorback suckers released into the Colorado River downstream of Lava Falls.

The adult fish entered the water March 16th wearing electronic tags that can be picked up by biologists.  By tracking the tagged fish, they hope to find other groups that may be spawning.

The razorback sucker is a fish found only in the Colorado River basin.  It was thought to have disappeared from GrandCanyon National Park, but it was rediscovered in October 2012 during surveys bythe Arizona Game and Fish Department.

This is the first timea study such as this has been conducted in Grand Canyon National Park.Fisheries biologists will attempt to track the fish during monthly river tripsoccurring between April and September.
