The Alaska Salmon Program is the oldest continuously running salmon research program in the world. Based out of the University of Washington, the program was established to investigate factors influencing salmon production during a declining salmon fishery in Bristol Bay, Alaska in the mid-1940s. The program strives to understand the ecology and behavior of salmon in relation to environmental changes through long-term research and implementation of new ideas and techniques.
This video highlights a small part of the core research conducted by the Alaska Salmon Program, and celebrates the hardworking researchers that have contributed to the program’s success.
...that was just before it tipped over.
The small fishing village of Astoria, Oregon, tried to scare off a pesky sea lion colony with a large fake mechanical orca. It was a cunning scheme, one that pitted the sly artifice of man against whatever it is sea lions have. But alas—nature won.
The plan to unleash the fiberglass orca—which is actually a licensed boat—was concocted to spook the sea lions using recorded whale noises and the visual threat of imminent death by top ocean-dwelling predator.
But the 32-foot-long fake whale’s maiden voyage didn’t exactly go... swimmingly.

The number of sea lions and the number of salmon they’ve eaten this year in the Bonneville Dam tailrace is more than double the twelve-year average, according to a May 12 status report by the U.S. Army Corps of Engineers.
Wipe out the habitat and wild fish, give all the water to agricultural interests, grow new fish in hatcheries, truck hatchery fish to ocean. The Aristocrats.
What do you do when you have 30 million young salmon ready for their big journeys downstream, but drought and development have dried your riverbeds to sauna rocks?
