This page is your mission-critical resource for safe and legal spearfishing on Guam. Following these protocols protects you, your dive partners, and the delicate marine environment we all share. Review these guidelines before every trip to stay prepared and compliant with local regulations.
Marine Preserves: No-Take Zones
Guam's Marine Preserves are vital to the health of our reefs and the future of our fishing community. The government has established strict "No-Take" zones where all forms of fishing, including spearfishing, are prohibited so reefs can recover. These boundaries are heavily enforced — always identify your location before entering the water, as penalties for violations are severe.
If you witness illegal activity in a marine preserve, call the TOKA Hotline: (671) 864-8652 immediately.
Dive Protocol: The Buddy System
Spearfishing is a high-stakes activity, and the most effective way to prevent accidents is to never dive alone. The "One Down, One Up" protocol ensures one diver is always on the surface, alert and ready to assist if their partner runs into trouble. This isn't a suggestion — it's the fundamental safety standard for every responsible diver.
When your partner is submerged, remain on the surface maintaining constant visual contact. Rotate roles for every dive.
Always keep eyes on your partner to monitor their descent, ascent, and recovery.
Pre-Dive Mission Checklist
Preparation is the hallmark of a disciplined diver. Before leaving for the coast, run through this checklist to account for conditions, equipment, and your communication plan. Being mission-ready means verifying these details before you step foot on the sand.
- Conditions — Verify surf, tide, and currents via NWS Guam: (671) 472-0900.
- Buddy — Confirm your partner is present and briefed on the dive plan.
- Gear — Ensure your float, high-visibility flag, knife, and whistle are functional.
