An instructor friend of mine has a map turtle he has trained to eat zebra mussels. Wouldn't it be kind of cool to train an army of turtles to decimate these little buggers, then turn 'em loose?
There are many species of map turtles, some broad-headed (eat more shell fish) & some narrow-headed (eat more small &/or soft-bodied invertebrates), & females get larger (& in the broad-headed maps have larger, more powerful heads) than males.
Those map turtles who eat mussels don't have to be trained; it's just natural. The proliferation of zebra mussels is just offering them a new food source. I wouldn't expect the female broad-headed map species to wipe them out, but they'll put a dent in them!
