Extra river water working to save silvery millow

ALBUQUERQUE (KRQE) – An attempt to trick the endangered Rio Grande silvery minnow into spawning appears to have been a success.

Officials began releasing extra water into the Rio Grande last week to mimic spring runoff.

Apparently the extra flows trigger the tiny fish’s reproductive instincts to spawn.

Officials says some eggs have been collected to be used at hatcheries to help the minnow’s dwindling population.

Despite releasing thousands of hatchery-raised minnows into the river each fall, the population is at its lowest level since monitoring began more than 20 years ago.
