The fragile little fish that swim around in dark tanks in a lab are the last hope for their kind.
SACRAMENTO, Calif. — The lab director who oversees their care, Tien-Chieh Hung, explained that when the Delta smelt captives are young, scientists at the UC Davis Fish Conservation and Culture Laboratory put snails in the black interiors of the tanks as a slow-moving mollusk cleaning crew.

He wasn't sure they would make it in the"home" that had never been their home."They might be too naive," he said."They might just become buffet for bigger fish." A federal law championed by Nixon, the Endangered Species Act, prohibits people from driving another species out of existence.
As Tufts University sociology professor Caleb Scoville has written, the fish was only recognized as a unique species because of the water infrastructure that was threatening to destroy their home:"Building extractive infrastructure," he said,"resulted in the proliferation of scientific knowledge about the natural systems it disrupted."
They retrieved the full 100 fish for the last time in the 2017-18 season, pulling in nets gently 15 times. The next season, the fish's population had a steep decline."We put out 10 times more effort" — 111 gentle pulls, Hung said —"but we can only get 28 fish."
