Blast fishing is an illegal and unsustainable practice that is often reported in Southeast Asia and Africa. Its impact on fish and reef-building corals is well documented, yet there is limited information on the effects on other larger species and near-shore predators. In recent years, several marine mammal strandings in the Philippines have coincided with underwater explosions associated with blast fishing. The goal of this study was to measure the hearing of stranded dolphins, including two spinner dolphins (Stenella longirostris) and two rough-toothed dolphins (Steno bredanensis), that were rehabilitated in Subic Bay at Ocean Adventure in cooperation with the Philippines Marine Mammal Stranding Network and Wildlife in Need. Hearing measurements were conducted using noninvasive auditory brain stem responses (ABRs). Test stimuli consisted of tone pips ranging from 8 to 128 kHz. The results indicated elevated thresholds and limited hearing range, including three individuals with no hearing response beyond 22.5 kHz. These results may indicate evidence of hearing loss associated with blast and related impulsive sound exposure.
