The way the cranes work is simple. The pot hanging from the bottom of the net carries bait, so that when the net is lowered into the water, it lies on the bottom with the pot at its centre attracting the fish.
When the fisherman judges that the time is right, the boom of the crane is brought up suddenly.
As the edges of the net are the first to rise, the little fish are caught and the pot acts as a counter weight causing them to slide to the centre.
The four arms of the boom are cleverly tied at the top with bicycle inner tubes causing them to flex as they rise so they don't break and the net is cushioned as it's lifted.
