It's Hatcheries to the Rescue

Once again hatcheries are going to ride to the rescue and save us all! The California Department of Fish and Game released 16.5 million fall chinook smolt as an effort to bolster horrendous returns of fall chinook in the states central valley streams.
16.5 million is a shit load of smolt! However it is pretty well known that fall chinook hatchery programs do not work out well and I would be surprised if this turned out to be any  different.
In Oregon we have our own hatchery fall chinook failures in nearly every coastal river from the Necanicum all the way south. We don't see the massive numbers like California is planting but we get about a .03% return. That makes those fish that do return about as rare as Sasquatch and about as expensive as an Imelda Marcos shoe buying trip.
This all reminds me of the saying "The height of insanity is continuing to do the same thing and expecting a different result"
So good luck California! I'm sure you are going to need it.

Here is the original press release from California F&W

The Department of Fish and Game (DFG) completed the release of 16.5 million young Sacramento Fall-Run Chinook salmon in northern California on June 15. The majority of the young salmon, called smolts, were placed into acclimation pens in San Pablo Bay prior to release, while others were released in rivers that flow to the bay. Smolts that survive to adulthood will return in two to four years to spawn in Central Valley rivers, boosting the recovery of the species in California waters.

“We hope this year’s above-average water flow and the use of a variety of release sites will improve the overall survival of the smolts and increase the return of adult salmon to their home rivers,” said Neil Manji, DFG Fisheries Branch Chief.
On June 8, the last major release of 650,000 Sacramento Fall-Run Chinook smolts took place near Mare Island Straits adjacent to San Pablo Bay. They were trucked from Nimbus Hatchery in Rancho Cordova to the site, confined in net pens to acclimate and towed out into the bay and released on the outgoing tide. The acclimation pens are operated by the nonprofit Fishery Foundation of California (FFC).
Since the collapse of the Sacramento Fall-Run Chinook salmon stocks in 2007, DFG has stepped up acclimation efforts and selected new release sites to help improve survival rates. This year, new sites for release included the mouth of the American River (to boost returns to the American River) and Eddos Harbor on the San Joaquin River near the Antioch Bridge (to boost returns to Mokelumne and Merced rivers).
“The releases went well,” said Biologist Kari Burr, FFC Acclimation Project Manager. “Once adults return and information is collected, biologists will be able to fine-tune release locations for the coming years.”
At release sites in the San Pablo Bay and Eddos Harbor, acclimation pens provided safe haven for the 3- to 5-inch-long salmon when they were released from pitch-dark transport tanks into bay and river waters. The pens allow the smolts to adjust to their new surroundings inside the safety of the net pens.
The release sites were selected in order to minimize in-river losses due to predation, pollution and other causes, and to help minimize the number of salmon that return to a different river than the one where they were raised.
The salmon smolts were raised at and trucked in from four DFG-operated Central Valley hatcheries.
