Salmon survivors

What happens when a hundred-year flood seemingly wipes out the salmon population in an Alaska stream?

The salmon simply recolonize and recover to pre-flood levels within four years.

That's what British scientists found in a study of Wolf Point Creek in Glacier Bay. Read about it here.

  1. It's that survival instinct. The salmon haven't figured out how to avoid those darn trawler drag nets out in the sea yet.

  2. Yes, actually, they have. Take a look at this year's negligible salmon bycatch in the BSAI trawl fisheries. Trawl mortality is a red herring folks. The real impact to salmon is in river.

  3. no, actually, they haven't. When one
    is killed, his genes don't impart the
    wisdom acquired thus to future generations. They're just dead.

  4. the reason for "negligible salmon bycatch in the BSAI trawl fisheries" is because they have been killed. no salmon left to catch.

  5. "Trawl mortality" is not a "red herring"! Blogger @9:09 PM states the reason why - "no salmon left to catch".
