I'm pretty ignorant about the proper ways to go about eradicating exotic
predatory fish from a watershed, but it seems to me that it could be
accomplished piecemeal. You could start by fencing off sections of
stream and eradicating whatever fish within that section and then moving
the fence further on. If nothing else it seems like you could create
refuges for the natives in this manner.
