Only good fishermen can catch blind Salmon ( must be sound and Oder)

Lateral line and scense of smell. If they follow the school of other salmon (using its lateral line) they can probably pick up scraps or be able to scense the injured fish from the others hitting the bait school.

Thanks!!! That's interesting.

Isn't there a chemical in the alewives that effects the salmons eyesight?

The scars that where on the one I caught where running latterly along its back, I've seen a fish that had been grabbed by a bird and this was different.

Thiaminase from alewives is far harder on salmon than thiaminase from smelt.  Poor growth, loss of appetite, immune system deficiencies, etc.

I'm a retired Maine F&W fisheries biologist. I have seen a few jet-black salmon in my career and some that were totally black on one side and totally normal coloration on the other side. The ones that are black on both sides are blind fish, and the ones that are only black on ones side are only blind on one side. The usual cause is eagle or osprey talons but the bird dropped the fish and the injury caused nerve damage followed by blindness.

that is really interesting, I had no idea.

If they are blind how do they feed ?

trout/salmon have some of the best sense of smell out of the game-fish world, better than Bass & Pike I believe.

Donít the Atlanticís supposedly find their home rivers with their sense of smell? I would think if they can travel thousands of miles via the smell of a river that they could catch a smelt or two.

yeah, something like that for sure I remember reading, I think they can sense the unique chemical trace of the water they were born in.
