Re: Bug seining?
JCW, that is a nice haul.
Crays, mays, stones, and Caddis larva.
Looks like a Caddis Pupa too.
One of my favorites, because they are easy for fish to catch, and a Bird's nest in tan or green will work. Impressionistic, just not on the surface.
Just remember, the whole river bottom is connected into a single ecosystem.
You rock worlds as it were, when seining, so be kind.
