Thirty-five years ago, the state launched the program to bolster waning white seabass numbers. Now the first scientific assessment of the program finds it had a stunningly low success rate.

Back in 1983, it seemed like a good idea.

Local populations of California white seabass, a favorite among recreational and commercial fishermen, prized for its mild, tender, flaky white flesh, were declining. While a fishery management plan didn't exist back then, sports fishermen had noticed a decline in their catches, and asked officials for help. State lawmakers then reached out to the marine biologists at Hubbs-SeaWorld Research Institute in San Diego to see if they could boost stocks by trying something unusual — raising the fish in a hatchery and releasing them into the sea.
