Blast Fishing

Blast fishing threatens a majority of tropical reefs and the food supply of a billion people. Fish blasters bomb above reef areas rather than use traditional methods of netting or spearing.  By bombing over the reefs they destroy the reefs and hence the homes of the fish, which takes years to recover.

ShotSpotter researchers have been working with the international environmental coalition Stop Fish Bombing (www.sfbusa.org) to develop blast location capability to enable marine law enforcement to intercept the illegal blasters. In coordination with legal and social reforms, timely reporting of blast locations to law enforcement can help prevent blast fishing.
