JB, Regarding tadpoles- After many years of checking stomach contents of several fish species in several different conditons, I have never found any evidence of fish consuming any amphibian- not saying it doesn't occur-but after literally hundreds of searches-nothing

I have read "somewhere" that they taste bad and aren't really a favorite.

FYI- also have checked lots of bullfrog stomachs- #1 forage - crayfish
quite a few rocks too?
