; therefore with education and proper regulations spearfishing can be the most ecologically sustainable form of fishing.

The very best free-diving spearfishers can hold their breath for durations of 2-4 minutes and dive to depths of 40 or even 60 meters (about 130 to 200 feet). However, dives of approximately 1 minute and 15 or 20 meters (about 50 to 70 feet) are more common for the average experienced spearfisher.

During the 1960s, attempts were made to have spearfishing recognized as an Olympic sport. This didn't happen. Instead, two organisations, the (IUSA) and the (IBSRC), maintain lists of world records by species and offer rules to ensure that any world record setting fish is caught under fair conditions. Spearfishing is illegal in many bodies of water, and some locations only allow spearfishing during certain seasons.

In 2007, the Australian Bluewater Freediving Classic became the first spearfishing tournament in the world to be accredited and was awarded 4 out of 5 stars based on environmental, social, safety and economic indicators.

Purposes of spearfishing
People spearfish for sport, for commerce or as subsistence. In tropical seas, some natives spearfish in snorkeling kit for a living, often using home-made kit.

Types of spearfishing

The methods and locations freedive spearfishers use vary greatly around the world. This variation extends to the species of fish sought and the gear used.

Shore diving

Shore diving is perhaps the most common form of spearfishing and simply involves entering and exiting the sea from beaches or headlands and hunting around ocean architecture, usually reef

 or sand. Usually shore divers hunt between 5 and 25 meters (about 17 to 83 feet) depth, though it depends on location. In some locations in the South Pacific, divers can experience huge drop-offs from 5 meters up to 30 or 40 meters very close to the shore line. Shark

s and reef fish can be abundant in these locations. In more subtropical areas, sharks may be less common, but other challenges face the shore diver, such as entering and exiting the water in the presence of big waves. Headlands are favored for entry because of their proximity to deeper water, but timing entries and exits is important so the diver does not get pushed onto rocks by waves. Beach entry can be safer, but more difficult due the need to consistently dive through the waves until the surf line is crossed.

Shore dives can produce a mixed bag of fish, mainly reef fish, but ocean going pelagic

s, but more commonly triggered devices such as spearguns. Speargun setups to catch and store fish include speed rigs, fish stringers.

The use of catch bags worn close to the body is discouraged because the bag can inhibit movement, especially descent or ascent on deeper freedives. Moreover, in waters known to contain sharks, it is positively dangerous and can greatly increase the risk of attack. The better option is to tow a float behind, to which is attached a line onto which a catch can be threaded. Tying the float line to the speargun can be of great assistance in the event of a large catch, or if the speargun should be dropped or knocked out of reach.

Boat diving

Boats, ships or even kayaks can be used to access off shore reefs or ocean structure such as pinnacles. Man made structures such as oil rigs and FADs (Fish Aggregating Devices) are also fished. Sometimes a boat is necessary to access a location that is close to shore, but inaccessible by land.

Methods and gear used for diving from a boat diving are similar to shore diving or blue water hunting depending on the prey sought. Care must be taken with spearguns in the cramped confines of a small boat, and it is recommended that spear guns are never loaded on the boat.

Blue water hunting is often conducted in drifts; the boat driver will drop one or more divers and allow them to drift in the current for up to several kilometers before collecting them.

Sensory deprivation

Sensory deprivation is the deliberate reduction or removal of stimulus from one or more of the senses.

. It can be difficult to determine the true size of a solitary fish when sighted due to the lack of ocean structure for comparison. One technique to overcome this is to note the size of the fish's eye in relation to its body - large examples of their species will have a relatively smaller eye.

Notably, blue water hunters make use of breakaway rigs and large multi band wooden guns to catch and subdue their prey. If the prey is large and still has fight left after being subdued, a second gun can be used to provide a kill shot at a safe distance from the fish. This is acceptable to IBSRC and IUSA regulations as long as the spearfisher loads it himself in the water.

Blue water hunting is conducted world wide, but notable hot spots include South Africa

Management of Spearfishing

Spearfishing is intensively managed throughout the world.

In Australia it is a recreational-only activity and generally only breath-hold free diving. There are numerous restriction placed by the Government such as Marine Protected Areas, Closed Areas, Protected Species, size/bag limits and equipment.

The peak recreational body is the Australian Underwater Federation. The vision of this group is "Safe, Sustainable, Selective, Spearfishng" and the AUF provides membership, advocacy and organises competitions.

Because of its relatively long coastline compared to its population, Norway has one of the most liberal spearfising rules in the northern hemisphere, and spearfishing with scuba gear is a widespread activity among recreational divers. Restrictions in Norway are limited to anadrome species, like atlantic salmon

Tips from Hawaiian Spearfishermen

One of the best tricks a spearfisherman can take advantage of is a fish's curiosity. Fish see their world with their eyes and with vibrations picked up by their lateral line. Experienced spearfishermen take advantage of this by moving very slowly in the water, and by using weights to carry them to the bottom rather than kicking of fins to minimize vibration.

Once on the bottom or in sight of a fish a spearfisherman will remain perfectly still, and lack of vibration in the water will usually cause the fish to come within spear range to investigate. Experienced shore spearfishermen will travel along the shoreline and prepare for an entrance to the water and enter and go straight to the bottom for as long as they can hold their breath.

Any large fish in the area will usually come to investigate the appearance and then disappearance of something, as no picture is available to their lateral line of a non moving object. Any rocks or other objects on the bottom that the spearfisherman can get close to will further disguise his appearance and warrant closer investigation by fish within 40 yards. Exiting the water and moving 40 yards down the shore usually produces another shot at a big one.

Experienced divers will carry several small pieces of coral or shells and when a fish is reluctant to come into spear range, rubbing or clicking of these usually draws them closer. Throwing up sand also will bring a fish closer and helps to camouflage the diver. Contact with coral
Coral

Corals are marine organisms from the class Anthozoa and exist as small sea anemone?like polyps, typically in colonies of many identical individuals....
 should be avoided as this may damage the reef. Blue water divers will float on the surface 100 yards from their boat and continue to rap a dive knife or a softer object against their spear gun until a big one comes to investigate.

In areas where many holes are available for a fish to hide in, a strong swimmer can clip his gun to his belt, and force a fish into a hole by swimming full speed and slapping his cupped hands on the surface with each stroke. Another shoreline technique for the big ones is to spear fish that are favorite prey of the desired species or collect the seaweed, mussels, etc. that they eat and chum them into the area.

Some think chumming
Chumming

Chumming is the practice of luring animals, usually shark, by throwing "chum" into the water. Bait often consists of fish parts and blood, which attracts sharks due to their keen sense of smell....
 the water is dangerous as it will draw sharks, but many big predator fish travel with reef sharks, and the instances of spearfisherman being attacked is a very low percentage of the total number of shark attacks. Sharks are like dogs,: if you cower from a bad dog, it will bite you, but if you stand your ground with a big stick, you can usually back it down.
