Pink salmon, also known as Humpies are in the creeks by the tons right now trying to avoid the bears and fishermen to get some spawning done. Frank was out a couple of weeks ago catching them and trout on his fly rod. Once the salmon hit the fresh water of the creeks they start to turn (or decay) pretty fast. These are not good to eat but fun to catch and release. Right now the streams are getting pretty stinky with all of the dying and decaying fish floating in them, but this is good, a stinky stream is a healthy stream. All of the dead fish will leave needed nutrients in the water for the smolts (baby fish) when they hatch.
This is a female Pink, you can see the white on her belly where the decay is starting, they also turn very dark.The male Pinks, once they hit fresh water start to "hump up" (ah, the name "humpies"). You can see it on the top of this fish. And the humps get larger then this the longer they are in fresh water.
