Spearfishing is a method of fishing that involves using a specialized spear to catch fish underwater. In saltwater or freshwater, it’s practiced for both recreational and subsistence purposes. 

Equipment you’ll need:

Speargun or *Hawaiian Sling: propels a spear towards the targeted fish. Alternatively, a Hawaiian sling, a handheld spear launcher, is also used in some regions.

Mask, Snorkel, and Fins: standard snorkeling gear is essential for underwater vision and mobility.

Wetsuit or Dive Skin: depending on water temperature, a wetsuit or dive skin can provide thermal protection. (see SENDYpedia post: Wetsuit, Drysuit or Dive Skin)

Weight Belt: helps maintain buoyancy control underwater.

Dive Knife: a safety tool for cutting lines or removing speared fish.

Float or Buoy: often attached to the diver with a line, the float serves as a marker and may also have a flag for increased visibility to other watercraft.

Safety Considerations:

Know the Local Regulations: familiarize yourself with local spearfishing regulations, including catch limits, species restrictions, and protected areas.

Buddy System: often done in pairs or groups for safety. Having a dive buddy increases safety by providing assistance in case of emergencies.

Dive Flag: when spearfishing from the surface, use a dive flag to signal to other watercraft that there are divers in the area.


Free Diving: most spearfishing is done through free diving, where you hold your breath while hunting underwater. Proper breath-holding techniques and diving skills are crucial. (see SENDYpedia post: Free-Diving)

Stalking and Ambushing: stealth and patience are needed to approach fish without alarming them, waiting for the right moment to take a shot.

Target Species:

Selective Harvest: targeting specific species while adhering to local regulations is the responsible way to spearfish.

Sustainable Practices: advocate for sustainable practices, emphasizing the importance of conservation and minimizing the impact on marine ecosystems.

Hunting Ethics:

Humane Kills: ethical spearfishing emphasizes humane kills, ensuring that fish are targeted in a manner that minimizes suffering.

Avoiding Overfishing: be aware of your impact on fish populations and avoid overfishing in specific areas.

Training and Certification:

Training Courses: take a spearfishing course to learn essential skills, safety practices, and ethical considerations.

Certification: Some regions or organizations offer spearfishing certifications to ensure that divers understand safety and environmental concerns.

Environmental Awareness:

Respect for Marine Life: respect the marine environment, avoid damage to coral reefs and other underwater habitats.

Leave No Trace: properly dispose of trash and debris, leaving the underwater environment as undisturbed as possible.

It's crucial to approach this activity with a commitment to safety, environmental conservation, and ethical practices. Before engaging in spearfishing, undergo proper training, understand local regulations, and adopt responsible hunting practices to ensure a positive and sustainable experience.

Spearfishing Destinations

Spearfishing is enjoyed in various locations around the world, each offering unique underwater environments and diverse marine life. 

Here are a few:

Hawaii, USA: a popular destination with warm waters and a wide variety of fish species. The islands offer a mix of reef and open-water spearfishing experiences. Oahu and Maui are particularly renowned for spearfishing.

Mediterranean Sea: known for its crystal-clear waters and diverse marine life, check out Greece, Italy, Spain, and Croatia to hunt species such as grouper, sea bass, and octopus.

Florida Keys, USA: surrounded by the Atlantic Ocean and the Gulf of Mexico, the warm waters are home to a variety of game fish, including snapper, grouper, and hogfish.

Baja California, Mexico: the Sea of Cortez, often referred to as the "Aquarium of the World," is a prime spearfishing destination for yellowtail, roosterfish, and various types of snapper.

Great Barrier Reef, Australia: a world-renowned marine ecosystem, you can target species like coral trout, Spanish mackerel, and various reef fish.

Bahamas: with clear turquoise waters, the islands offer opportunities to target species like grouper, snapper, and the infamous lionfish.

French Polynesia: including Tahiti and Bora Bora, it’s known for stunning coral reefs and diverse marine life. You can find parrotfish, trevally, and surgeonfish.

Cabo Verde: an archipelago off the west coast of Africa, it’s becoming increasingly popular for spearfishing. Cabo Verde's waters are home to a variety of game fish, including tuna, wahoo, and dorado.

Seychelles: situated in the Indian Ocean, and known for pristine coral reefs and rich marine biodiversity, you can target species like grouper, snapper, and the elusive dogtooth tuna.

Palau: in the western Pacific Ocean, it’s famous for its clear waters and unique underwater landscapes. You’ll encounter a variety of pelagic species, including tuna, wahoo, and billfish.

New Zealand: the coastal waters of the North Island and South Island provide access to species like kingfish, snapper, and crayfish (lobster).

Cozumel, Mexico: located in the Caribbean Sea, and known for vibrant coral reefs and clear waters, spearfishers can target species like snapper, grouper, and permit.

Before embarking on a spearfishing trip in unfamiliar locations, it's crucial to research and adhere to local regulations, obtain any necessary permits, and prioritize safety. Consider joining guided tours or hiring local spearfishing guides to ensure a positive and responsible experience in these diverse underwater environments.

*Hawaiian Sling

A simple and effective tool, used to catch fish underwater, it dates back to ancient times. It’s still widely used today, particularly in areas where traditional spearfishing methods are practiced. 

A bit about the Hawaiian sling:

Design: consists of a long, cylindrical pole or tube, typically made of lightweight and durable materials such as fiberglass or aluminum. At one end of the pole, there is a surgical tubing or bungee cord that acts as a sling. The other end features a pointed, barbed spear tip.

How It Works: operated by stretching the surgical tubing or bungee cord and fitting it onto the notches or a small peg on the pole, creating tension. To shoot the spear, grip the pole and extend it toward the targeted fish, releasing the tension on the tubing. The spear is propelled forward with enough force to penetrate the fish.

Advantages: Simplicity: it’s a simple tool, making it easy to use and maintain. It doesn't have complex mechanisms like some spearguns. Compact and easy to transport, it’s popular among free divers and spearfishers who prefer a minimalist approach.

Versatility: suitable for hunting a variety of fish species in different underwater environments, including coral reefs, rocky areas, and open water.

Legal Considerations: may be subject to regulations in some locations. Check local fishing laws and obtain necessary permits before using it to fish.

Skill, Precision & Training: though relatively simple, it requires skill and precision to accurately aim and shoot the spear to catch fish. Proper training and practice are essential for safe and effective use. Novice spearfishers can benefit from instruction or guidance from experienced users.

Safety Considerations: when using a Hawaiian sling, be aware of your surroundings and the presence of other divers. Clear communication and adherence to safe diving practices are essential.

Sustainability: this method of fishing emphasizes sustainable fishing practices. Selective harvesting and adherence to catch limits contribute to the conservation of marine ecosystems.
