There are different types of nets available on the market, but you have to choose one that is feasible to capture a large wels catfish.
You have to make sure the net is strong and the big specimens do not get away.
The net is made up of two net funnels that are directed inwards and are made of a long net tube.
This net is kept open by means of a glass fiber or metal circle.
The structure and the fastening and anchoring are designed to allow a fish to enter but prevent it from coming out.
To use a circular net, you should check with local authorities if it is legal to use such a net in that area.
