A gillnet catches fish by their gills. It works like this: the twine of the netting is very thin, and either the fish does not see the net or the net is set so that it traps the fish. The meshes of the net hang wide open. If the fish is too small for the mesh it will swim right through and get away.
How do fishing cast nets work?
It is a circular net with small weights distributed around its edge. The net is cast or thrown by hand in such a manner that it spreads out while it’s in the air before it sinks into the water. Fish are caught as the net is hauled back in.
How do you fish with a fishing net?
Use a scooping motion that goes down and below the fish and then bring the net upwards towards the surface. If the fish runs for deep water, they will swim directly into the net. If they decide to jump, your net is already directly below their bodies, so you have a better shot at catching them mid-air.
