The bass that we previously stocked in the ponds have demonstrated their predatory nature.  There were a lot of frog eggs and tadpoles hatching in the ponds – due to the lack of predators.  Recently that has changed as I have observed the small bass prowling along the banks to catch bugs and tadpoles near the edges.  The other night I watched three bass seemingly hunting in a shallow area as a pack.  I can’t say they were working cooperatively, but I was reminded of the raptors in Jurassic Park.  Needless to say the tadpole population is greatly reduced and very skittish.
