[QUOTE=Michael MacFarlane]Do we have to manually control them to catch and eat fish, or will they do that on their own?[/QUOTE]
It won't be a 24-7 control over these things, it'll be like a UAV program in a way, instead of a unmanned aircraft, it's a shark. When the missions over, the shark returns to its holding craft/facility and they feed it there. Of course, the beautiful thing about these things is that unlike UAVs, they don't have to come back to refuel, you can cut transmission to them, and they'll go find food in the area while another shark takes its place in the mission, and rotate between sharks to monitor something.
