Video: Silvery Minnow

The Silvery Minnow Refugium in Los Lunas, N.M., is not your average hatchery. The place has been built to mimic the Rio Grande in order to breed the endangered species. I met Douglas Tave, the refugium manager, when the construction site looked like a skate park -- a snaking river of cement. Months later, when this video was made, the place was full of water and almost ready for the fish.
