U.S. proposes removing Colorado River fish’s endangered status

The US Fish and Wildlife Service said it would propose to reclassify a rare Colorado River Basin fish called Razorback Sucker from endangered to endangered status.

It does so after multi-year, cross-state efforts across the U.S. Southwest to replenish the population.

A proposed formal resumption, due to be published in the federal register on Wednesday, would classify the fish as no longer critically endangered.

It would require ongoing management of the survival of the razorback in the Colorado River and several major tributaries.

The Fish and Wildlife Service initially said it would recommend the change in 2018.

Hundreds of thousands of razorbacks once thrived in the Colorado River and its tributaries, which flow through seven states and Mexico.
