Acoustic Detection

SFB uses hydrophones to pick up loud impulsive sounds that could be fish bombs. If these sounds are classified as actual bomb blasts, their arrival times will be used to locate and alert a fish bombing incident.

Their development has been driven by the Navies of the world, principally to detect submarines and torpedoes.

In 2003 it was shown that they readily detect fish bombs.

In 2015, it was shown that the expected range of detection is 30-50 kilometers.

Hydrophones vary in quality and price, so an important goal of the Stop Fish Bombing! project is the evolution of low-cost hydrophones.
