Well, negative or not, you just summed up my life's fishing experience, so hey.

Watching the fish swim around with your lure would be a once in a lifetime experience, I think, and if you could find someway to get it livestreaming to the net (which there's got to be a way), you could probably charge a subscription fee or sell popcorn or something. I'm sure there's plenty of anglers that would want to study the fish to see if they could pick up on tendencies, and there would be kids who were just fascinated by the fish running around.

I wonder what the clarity and the lighting is like on the camera, though. It must be pretty decent if you can see underwater.
