Shorty, if the fish aren't eating the bullfrog tadpoles, why the rescue mission?
Frog legs!

On a sunny afternoon there's many more, but does your shoreline look anything like this when you walk by?
http://youtu.be/HDTEQMK1ggoI asked about this last year and there's something to do with a pheromone put off by the BF tadpoles that LMB (and other fish) don't seem to like. Maybe they're getting eaten but I have literally thousands of them, especially within the Coontail masses.
I've also read that BF tadpoles can/do eat FA. Whether that's true or not I can't say for sure, but after using Cutrine + on FA last spring, and a Fluridone treatment for DW and CT in July, I had NO recurring FA last year and minimal this year. Due to tadpoles? Don't know but I love having them in the pond for the sounds and the frog legs!

PB Rocks!
