Global Observations of Blast and Poison Fishing

Blast and poison fishing occurs primarily in Southeast Asia, the western Pacific, and eastern Africa. Areas of threat shown here are based on survey observations and expert opinion. Areas classified under moderate threat are those where blast and/or poison fishing occurs occasionally (i.e., once a month). Areas under severe threat are those where blast and/or poison fishing occurs frequently (i.e., once a week or more often). Unclassified areas are considered under low threat for either blast or poison fishing.
