GRAND CANYON NATIONAL PARK, Ariz. (AP) — An endangered fish species believed to have been missing from Grand Canyon National Park since the 1990s has been found spawning in the lower Colorado River.

U.S. Department of the Interior officials said Wednesday that researchers discovered larval Razorback suckers in the river that runs through the canyon in April and May.

Experts say it indicates that suitable habitat is available to support larger populations of the species.

Razorback suckers were once widespread and abundant throughout the Colorado River and its tributaries from the Green River in Wyoming to the Gulf of California.

But because of basin-wide alterations in habitat and the introduction of non-native species, spawning and survival to adulthood for the Razorback suckers were known to occur only in Lake Mead National Recreation Area on the Arizona-Nevada border.
