I, Robot redux

Ok, those Japanese are just getting out of hand now. First it was the robot health care aide, now it's a robot carp. Yes, a CARP. You know - a giant goldfish! It is patterned after a koi, the highly prized decorative fish that so many Japanese (and Americans, too) keep as pets. The goal is to use it to monitor fisheries and possibly oil platforms.

Word is they actually taste better than real carp.
