Floating trawl is usually much larger than the bottom trawl. It is designed and rigged to work in midwater, including surface water. The front net sections are very often made with very large meshes or ropes, which herd the fishes towards the net.

 

The meshes in the trawl net gets smaller the nearer you get to the bottom of it. In some of the larger trawls you will find that the ropes used for the meshes are produced with a special kind of rope to ensure the net spreading easily in the water.
