Thanks tracy K, I posted this question because I work for an electronics company and we have many devices used on animals/equipment for identification/tracking. We also have tech for tracking with GPS. I know there are devices out there, and I know sasquatch exist. This would be an ideal way to track, with baited fish or similar, once the device is in the system. Nano technology is also used in aeronautics, that is where most home tech comes from. cheers mark.
