ALBUQUERQUE, N.M. — Federal wildlife managers are considering petitions by environmentalists that call for protecting two more fish found in the Rio Grande.
The U.S. Fish and Wildlife Service says there’s enough information in the petitions to warrant further study of the Rio Grande chub and Rio Grande sucker.
The chub is found in drainages of the Rio Grande and Pecos River as well as the headwaters of the Canadian River. The sucker is native to the Rio Grande and its tributaries in southern Colorado and Mexico.
The petitions argue that dams and irrigation have altered flows and the fishes’ habitat has been fragmented.
The Fish and Wildlife Service says it will begin a 12-month review to determine whether the chub and sucker should be listed under the Endangered Species Act.
