Whats this on my FF?

I'm not the best with reading my FF, but this looks like pretty solid returns.  This is in Point Defiance just a few days ago.  Salmon?

A couple more pics, just because...

Another..

I've been seeing screens like that from camp sealth to Point Gibson----they seem to be small silvers, those concentrations are most commonly between 25 and 50 feet, I put my downrigger in the middle of the cluster and caught a shaker silver.  LOTS of small silvers jumping, too.  At 90 feet, caught a 22incher.

My .02 is that they are baitfish.  It's the little arches you see around them that are salmon feeding on them.

Silvers usually stay on the surface to 30 feet.
