A few months back some one posted a video of catfish in a floating cage with blower motors on one end. The bubbles would run up a curved hood into the cage making a very big current. The floating raft had sides you could walk on to feed and net out losses.

The feed was floating and there was a solid area at the back so the food would not get washed out. The netting would let water pass out the back but keep the fish in the cage.

You could float these in a pond and basically hook power to them and load them with fish.

The video was showing how dence you could have the fish because of the flow of water passing through the cage.

If anyone could help me find information on this system that would be great.

Cheers Don.

This not ring any bells with anyone?

I think it was an aluminum bottom and sides with mesh ends. At the one end there was a curved hood that with all the air bubbles from the blowers mounted on top of the hood would move a bunch of water through this shoot. All the waste would then settle to the bottom of the pond.
