....It was to much fun to be gone already...
LOL easy there big fella.
#1. They're not gone. You just haven't found what part of the river they moved to. My theory is that the plankton they feed on is deeper when we can't find them it's just because they are feeding deeper.
The only advice I can give is to try another part of the river. I wish I had a more certain answer for you.
