They Are Coming! Salmon Poster
An easy nine miles from the city of Juneau, a portion of a small non-glacial tributary creek nestled among alder, cottonwood and beds of dense, lush moss and understory vegetation is again sharing its ancient story of birth, death and renewal: sockeye and coho salmon are swimming home to spawn.
Yet visitors who want to take in this yearly natural story can view the wonder from the comfort of their own homes via a live online streaming from an underwater camera. Read more »

After searching 15 years for a way to combat a devastating disease among salmonids (salmon and trout), researchers at Washington State University (WSU) and the University of Idaho (UI) found an answer inside the fish itself.
Dr. Kenneth Cain’s team at UI’s Aquaculture Research Institute cultured a bacteria from the fish’s gut (designated Enterobacter C6-6) and found that it inhibited the growth of Flavobacterium psychrophilum, the organism that causes Coldwater Disease.
Cain and Dr. Douglas Call, his WSU-based research partner since 2001, found that by adding C6-6 to fish feed as a probiotic they could limit the damage caused by Coldwater Disease – but they’re not quite sure why. “We know that C6-6 produces a toxin,” Call said. “This toxin kills the bacteria although we’re trying to get more funding to figure out how this works in the fish itself.” Read more »

Since the second week in July, locals and visitors alike have congregated on the viewing platforms above Steep Creek near the Mendenhall Glacier Visitor Center in Juneau, Alaska to enjoy the sockeye salmon migration.
From mid-July through the end of August, the sockeye salmon enter the creek to dig redds (nests), find mates and spawn. For thousands of viewers this annual show is seen not in person but on the screens of their computers or smart phones, thanks to the Steep Creek salmon cam. Read more »

Gordie Reeves looks at salmon the way a man would look at pictures of his family. For Reeves, the salmon species is pretty much the best fish species around.
“They are dandelions of the fish world,” said Reeves, a research fish ecologist with the U.S. Forest Service. “They have this mechanism or strategy for persisting. We are under the illusion that everything in a stream should be perfect all the time, but that’s not true. It’s not the way the world works. Salmon do a terrific job under really incredible odds.”
Nature lovers can get a glimpse of salmon runs through a live streaming video. For the second year, the Forest Service is streaming from the bed of Juneau’s Steep Creek on the Tongass National Forest in Alaska. Read more »

Alaska’s Chugach and Tongass national forests are sometimes referred to as salmon forests, producing all five species of wild Pacific salmon: king, coho, sockeye, pink, and chum.
Salmon is vital to Alaska’s economy, and last year’s statewide commercial salmon harvest is being noted as a banner year. The Alaska Department of Fish and Game announced the salmon harvested in 2013 set a new record at 272 million fish.
About 45 percent, or 122 million, of these commercially harvested salmon relied on habitat managed by the U.S. Forest Service. Much of the harvest consisted of pink salmon, the most abundant of salmon found in Alaska. Don Martin, the aquatic and fish program leader for the Alaska Region, said that 95 percent of the habitat where pink salmon spawn in Southeast Alaska is on the Tongass National Forest. The work of Forest Service fish biologists contribute to the health and viability of these salmon. Read more »
Through the end of August, you will get the chance to be entertained as sockeye salmon swim along Alaska’s Steep Creek as the adults spawn before swimming to their final deaths.
The Forest Service has placed the salmon cam in the creek on the Tongass National Forest so viewers world-wide have the opportunity to view fish in their natural setting. The ability to watch salmon in the wild is a treat for many people, but the underwater camera gives you a more intimate, unique look. Read more »
