Baby Salmon Released in California

Monday, June 21st, 2010

Over in San Pablo Bay (California) the state’s Department of Fish and Game recently released over 16 MILLION young salmon into San Pablo Bay. They hope this will help the struggling salmon population recover from recent declines.

The fall run of chinook, or king, salmon in the Sacramento River provides much of the fish found off the California and Oregon coasts. But since 2007, this population has dipped to levels so low that fishing has been canceled or curtailed greatly.

Fishermen blame the decline on the delta’s vast series of pumps which divert water to farms that the salmon need to survive. Others blame changing ocean conditions.

I for one, am glad, that California has taken the initiative to aid the salmon population.

Microchipped Salmon

Monday, November 9th, 2009

Fish biologists studying salmon have historically lost track of their fish, particularly when they get into the streams and creeks in the Pacific Northwest.

Scientists have developed a new way to help track the salmon heading home. They’ve installed giant antennas in over 20 rivers and streams to help track the microchipped fish. The arrays are powered with a propane generator and solar panels. Information gathered is relayed via satellite and posted in real time on a public website.

Three of the new research antennas are now in place in the Entiat River in Washington state, seven in the Wenatchee River and its tributaries in central Washington, eight in the John Day River system in northeastern Oregon, three in central Idaho’s Lemhi River basin and four in Idaho’s South Fork.

Idaho’s Not Just for Potatoes

Friday, November 6th, 2009

Idaho’s State Department of Fish and Game says the salmon have returned. This years tracking totals over 800 sockeye salmon, the most since they started tracking the fish in 1985.

Some of the salmon eggs harvested will be raised in fish hatcheries. Some adult sockeye were released in area lakes to spawn naturally.

The captive breeding program began in the 90’s. Sockeye (Oncorhynchus nerka) were the first Idaho salmon listed under the Endangered Species Act.

Redfish Lake sockeye enter the Columbia River in summer and reach Redfish lake in late summer. They spawn in October in the lake shallows. The young fish emerge in spring and feed in the lake for a year or two before beginning their migration to the ocean. Most spend about two years in the ocean before returning.

The fish have a long way to go to return to their numbers of the late 1800’s when their numbers were estimated at 25-35,000, but it’s a great start.
