Fishing is the number one recreational pastime in the United States.
The increasing demand on already over-utilized public fishing waters provides an opportunity for the development and expansion of commercial fishing facilities. Fee-fishing, the practice in which anglers pay for the right to fish or for any fish that are caught, can bridge the supply shortfall for quality fishing opportunities, especially near urban areas. Fee-fishing can provide profits for the owner, social and recreational benefits for the community, and a market for locally produced fish. All rights reserved.
