Abstract:

We have been conducting genetic monitoring of the wild middle Rio Grande population of Rio Grande silvery minnow on an annual basis since 1999. We has also been monitoring stocks of fish bred and/or reared in captivity and then released to the Rio Grande in New Mexico since 2002 and of fish released to Big Bend (TX) since 2008. In 2012, we continued these efforts by genotyping 517 wild fish from the middle Rio Grande, NM, and 700 (representing 14 lots) progeny of captive spawning and/or rearing conducted at Dexter National Fish Hatchery and Technology Center, the Albuquerque Biological Park and the Los Lunas silvery minnow refugium.
