A nonprofit organization called Stop Fish Bombing! (SFB) is combating a famously destructive and illegal fishing practice. By adapting technology developed by the California company SST Inc. to detect gunshot locations, the nonprofit hopes to catch villains who are destroying the underwater world through fish bombing.
Fish bombing — also called blast or dynamite fishing — uses explosives to stun or kill fish, making it easy to gather them up en masse. Dynamite doesn’t discriminate. Everything from fish eggs to dolphins to coral reefs die in the blast. While the short-term effect means an easy haul for fishermen, the long-term effects spell doom to the fish, the fishing industry and reef-related tourism. Eventually, the repeated blasts create dead zones, destroying biodiversity and whole ecosystems. Fish bombing is practiced in many places around the world, including Tanzania, Malaysia and Nicaragua.
SFB has adapted urban tech for the marine world. Law enforcement in more than 90 cities use SST Inc.’s ShotSpotter technology to find shooters. Acoustic sensors are placed throughout neighborhoods. When somebody fires a gun, multiple sensors detect and timestamp the sound. “The precise location of the gunshot is determined based on the time it takes for the sound of the gunshot to travel to each individual sensor, effectively triangulating the sound. The exact location of the detected gunshot is indicated by a dot on a map,” according to a video on the SpotShotter site. Back at the command center, analysts use audio technology to differentiate gunshots from other percussive sounds.
Translating this tech to an underwater environment, SFB places sensors on piers and boats to locate blasts. In one success, the nonprofit triangulated the positions of 16 explosions in Sabah, Malaysia within 60 meters in about 10 seconds. They were able to safely detonate 19 bombs. By photographing boats in the vicinity at the time of blasts, SFB can help local law enforcement efforts.
SFB, based in Hong Kong, was founded by Scubazoo, SST and Teng Hoi Conservation Organization. Scubazoo is a production and filming company specializing in marine and jungle locations in South East Asia. Teng Hoi focuses on environmental problems and education in Hong Kong and internationally. In addition to its work on fish bombing, SST has also adapted its ShotSpotter technology to deter rhino poachers in South Africa.
Environmentalists now have one more tool in their race to save reefs. George Woodman, founder of Teng Hoi Conservation Organization, said, “Fortunately, we now have the technology to detect and locate fish bombs as they happen and publish this information on tablets and phones for access by everyone.”
