A team of aquatic biologists use a net to collect endangered fish from the Double Mountain Fork of the Brazos River in a rural area just west of Sagerton, Texas, Friday, Sept. 16, 2011. The team from Texas Tech and the Texas Parks and Wildlife Department are collecting two species of minnows from the shrinking waters of the West Texas river that have stopped flowing due to the worst drought in decades, therefore, impeding the fish's ability to spawn.
