A fishing license is needed primarily to help conserve fish populations and their habitats. The fees collected from fishing licenses fund important conservation efforts such as habitat restoration, fish stocking, and pollution control, which ensure sustainable fish populations and healthy ecosystems. Additionally, fishing licenses help regulate fishing activities to prevent overfishing, support research for better fishery management, and provide educational programs about responsible fishing practices. Holding a valid fishing license also ensures compliance with legal regulations and helps avoid fines or penalties. This licensing system benefits not only fish populations and the environment but also anglers, by maintaining a healthy and balanced ecosystem for continued recreational fishing.
