Bubbling Ponds Hatchery

摘要

As a biologist with the Arizona Game & Fish Department, David Ward, 38, spends part of his time raising rare and endangered woundfin minnows. Government grants are tough to come by, so Ward nurtures the fish in 12-foot shipping containers that once held fuel tanks and JDAM missile guidance systems. Aquaculture suppliers typically charge at least $3,000 per tank. Ward's converted containers cost $100 each—cheap enough for Ward to float the opera tion himself.
