Oh yes we use cos when you're dredging, you see when the eels came in the mud, eels always go in the mud in the winter time, you don't, many eels swirl out, they go in the mud and when you're dredging and they're going into the hopper, cos they used to get stunned and they used to swim round right down the top of the water and they used to come up to the side, and if they come up to the side you could have your  knife and just come here, cos they were stunned, pick 'em out.
