How do they get the coating in the first place? They create it of course. I'm sure they can create more if this scrapes it away.

- tombrossman 12y agoThey can create more just as your body would create scar tissue if I scraped some of your skin off. Meanwhile, the exposed area is far more likely to become infected as your skin no longer protects it. Not a perfect analogy but it illustrates my point well enough.
- gnarbarian 12y agoBetter than them dying at the bottom of the damn dam.
- zizee 12y agoSince 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).
- seanflyon 12y agoCorrect. I didn't believe you until I checked Wikipedia.
