Another View: A smelt hatchery can save the fish

From the Sacramento Bee, this commentary, written by Steve Thompson, regional director of the U.S. Fish and Wildlife Service for California and Nevada. He is responding to the June 30 editorial “Little fish, big bad idea / Smelt hatcheries would just be a waste”:

An editorial about Senate Bill 994 implied that hatchery rearing of Delta smelt is a “nutty” idea, and that we should not waste “our money on smelt factories.” People should not be so quick to dismiss a Delta smelt hatchery.

The U.S. Fish and Wildlife Service, the federal agency charged with conservation of the nation’s fish and wildlife, has used captive propagation to bring a number of species back from the brink, including the California condor, black-footed ferret, whooping crane, Lake Superior lake trout, Gila trout in New Mexico and winter-run Chinook salmon in the Sacramento Valley. A goal of the Fish and Wildlife Service is to restore fish populations to self-sustaining levels. We operate a national fish hatchery system of 70 facilities throughout the nation. Many of these facilities use the latest in aquaculture technology and genetic research to produce fish to help restore a number of imperiled and depleted species.

To be successful, restoring Delta smelt populations would also require improving its habitat in the Sacramento-San Joaquin Delta. But, just as releasing Delta smelt into a degraded Delta will fail to restore them to self-sustaining levels, so will habitat restoration efforts fail if there are not enough fish to rebuild the population. Unfortunately, that is a very real possibility because current data suggest Delta smelt populations might already be so low that they cannot be recovered without supplementation.
