Since this is to help them on their final stage of their migration to the spawning grounds (after spawning they die), I don't think infection is a big issue.

- Turing_Machine 12y agoRight. At that point their lifespan is measured in days anyway.
- Gravityloss 12y agoNot all salmon die after spawning.
- Turing_Machine 12y agoAll Pacific salmon (which is what these are) die after spawning. A few Atlantic salmon (about 10%, ATW) will survive to make another trip. The Pacific species basically start to decompose as soon as they hit fresh water. Once they've spawned, they fall apart like something out of a bad horror movie. I've seen semi-alive fish that you could stick your thumb through without any effort (usually snagged by a tourist who's proud of his accomplishment).
