This image was taken with a DIDSON-LR using
the Large Lens Set on Alaska's Kenai River.
At 60m, two king salmon are swifty
followed
by 2 sockeye salmon.
(NOTE:
You may see a white line in this film.
It occurred during
conversion of the file to a gif.
It is NOT a sonar
issue. We're working on getting rid of it!)
