Angling safety & ethics
- Know the regulations
- Check local fishing rules, seasons, size limits, and license requirements to ensure legal and sustainable angling.
- Handle fish responsibly
- Use wet hands, minimize air exposure, and release fish gently to improve survival rates when practicing catch-and-release.
- 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
- Pack out all line, hooks, bait containers, and trash. Discarded gear can injure wildlife and degrade waterways.
