Angling safety & ethics

Know the regulations
Check local fishing rules, seasons, size limits, and license requirements to ensure legal and sustainable angling.

Choose the right gear
Match your rod, line, and tackle to the species and conditions to increase success and reduce unnecessary harm to fish.
Respect the waterway
Avoid disturbing habitat, prevent bank erosion, and keep a safe distance from spawning areas to protect ecosystems.
Keep it clean
