Pumps control the current to mimic the natural flows of the Rio Grande. The bottom surface is a mixture of sand, gravel and silt. The breeding goal of the $1.7 million facility was to produce 50,000 minnows this year - with 25,000 minnows to be returned to the river and 25,000 to be retained for future captive spawning.
The spottail shiner or spottail minnow (Notropis hudsonius) is a small- to medium-sized freshwater minnow. It can be found as far north as Canada and as far south as the Chattahoochee River in Georgia. These shiners live in lakes, rivers, and creeks.

When the Devils River minnows were first classified as threatened in 1999, a group of organizations including the Texas Parks and Wildlife Department, the City of Del Rio, Texas, and the U.S. Fish and Wildlife Service are involved in a Conservation Agreement to assist the minnows’ recovery to the point that it is no longer a threatened ...
With over 300 known species, there are more species of minnows native to North America's fresh waters than any other fish. [2] Minnows can be hard to distinguish because many look alike. [3] All minnows have one dorsal fin, ventral fins near the anus, a lateral line system (in most species), and smooth, round cycloid scales. [4]
