Researchers using underwater acoustic sensors have tracked the frequency of bomb fishing across Indonesian coral reefs, according to a report from dialogue.earth. The monitoring effort, also highlighted by the Zoological Society of London (ZSL), recorded a blast occurring on average once every 62 minutes within the surveyed areas.
The findings, published on August 14, 2026, detail how the sonic tracking system identified the distinct sound signatures of explosive charges used in illegal blast fishing. This method, which involves detonating homemade bombs to stun or kill fish, causes severe physical damage to coral structures and often results in the loss of entire reef habitats. According to dialogue.earth, the acoustic data provides a clearer picture of how widespread and persistent the practice remains in Indonesian waters.
Bomb fishing has long been a known threat to the region's marine biodiversity, but quantifying its exact scale has been difficult. The use of passive acoustic monitoring offers a new way to measure activity without requiring visual confirmation or patrol vessels in the area. The ZSL report, which accompanied the dialogue.earth coverage, emphasized that the frequency of blasts—one roughly every hour—underscores the pressure that local reef ecosystems face from this destructive activity.
The data from this acoustic tracking effort could inform future enforcement strategies. Conservation groups and marine authorities may use such real-time monitoring to pinpoint hotspots and deploy resources more effectively. What remains to be seen is whether these findings will translate into stronger on-the-water action against bomb fishing crews.
