5 Eco-Friendly Tips to Protect Our Oceans While Spearfishing

5 Eco-Friendly Tips to Protect Our Oceans While Spearfishing

Spearfishing is an incredible way to connect with the ocean, experience the thrill of the hunt, and source your food sustainably. However, as divers, it’s essential to ensure our actions don’t harm the marine ecosystems we treasure. Here are five simple, eco-friendly tips to help protect the ocean while enjoying this exciting sport.

1. Target Plentiful Fish Stocks

One of the best ways to spearfish sustainably is by focusing on fish species that are abundant and well-managed. Popular catches off Cairns on the Great Barrier Reef include coral trout, buffalo emperor, Spanish mackerel, jobfish, and tuskfish. Targeting these plentiful stocks helps maintain the balance of marine ecosystems and supports sustainable fishing practices. Avoid species that may be vulnerable or under pressure and always follow local guidelines to ensure ethical and responsible catches.

Pro Tip: Research which species are abundant in your area and learn to identify them accurately to avoid mistakes. Remember, everything looks a little different in the depths of the ocean, and color begins to fade. We’ll deep dive into this in another post—stay tuned for more on this fascinating topic!

2. Follow Local Regulations

Every region has unique rules regarding which species can be caught, their size limits, and the seasons they’re available. Adhering to these regulations ensures fish populations remain healthy and thrive for generations to come.

Pro Tip: Download a guide or app that provides up-to-date information on local fishing laws and protected species.

3. Avoid Sensitive Habitats

Coral reefs are critical marine habitats that support a wide variety of marine life. When fishing at the reef, ensure you avoid overfished or protected areas. In Australia, marine parks are divided into zones:

  • Marine Park Zoning Explained

  • Green Zones (Marine National Park): No-take areas where all forms of fishing and collecting are prohibited to protect sensitive ecosystems. Low-impact activities like snorkeling, boating, and swimming are allowed.

  • Yellow Zones (Conservation Park): Areas with limited fishing allowed. Fishing is restricted to one line and one hook per person or trolling with up to three lines per person and a maximum of six hooks.

  • Blue Zones (General Use): Areas where most recreational fishing is permitted, balancing reasonable use with conservation.

  • Dark Blue Zones (Habitat Protection): Protect sensitive habitats by restricting damaging activities. Trawling is not permitted.

  • Pink Zones (Preservation): Strictly no-go areas where all extractive and recreational activities are prohibited without a special permit.

  • Olive Green Zones (Buffer): Limited to trolling for pelagic species such as marlin, mackerel, and tuna.

  • Orange Zones (Scientific Research): Reserved for research purposes, requiring permits. Some areas are restricted-access and off-limits to the public.

  • Brown Zones (Estuarine Conservation): Protect estuarine areas while allowing traditional and sustainable activities like line fishing and crabbing.

  • Cream Zones (Commonwealth Islands): Include intertidal areas on Commonwealth islands, allowing sustainable recreational and traditional activities.

Choose areas responsibly and stay informed about the zones to minimise disturbance to marine life.

Pro Tip: Always check the latest zoning maps and regulations for your location to ensure you’re fishing within the rules.

4. Use the Right Gear Responsibly

  • Choose durable, high-quality gear to reduce waste and minimize the need for frequent replacements.

  • Properly dispose of broken gear or recycle parts whenever possible.

  • When using lines or nets, ensure they are handled responsibly to prevent entangling marine life. Dispose of old line and rubbish responsibly by keeping it in a secure place until you're back on shore. You could even repurpose it into something creative like a piece of artwork.

Pro Tip: Store your gear securely to avoid losing it in the ocean, where it can become harmful debris.

5. Take Only What You Need

Sustainability starts with restraint. Only target the fish you’re sure you’ll eat, and avoid overfishing in one area. This practice ensures a balanced ecosystem and preserves resources for other divers and future generations. If you accidentally kill a fish you’re not going to eat, give it back to the ocean by using it as bait or chum (burley). This way, it doesn’t go to waste and still supports the ecosystem.

Pro Tip: Practice precision and aim for ethical, clean shots to avoid injuring non-target species.

Final Thoughts

Spearfishing is about more than the catch; it’s about connecting with the ocean, having fun, and respecting its delicate balance. By targeting plentiful fish stocks, following local regulations, avoiding overfished or protected areas, using gear responsibly, and taking only what you need, you can enjoy the thrill of the hunt while safeguarding the underwater world.
