Spearfishing World Records
The "sport" of spearfishing is defined by the method of harvesting a fish one a single breath hold. To qualify for a world record you need to use this method and record your fish on a certified scale. You can also qualify for a world record via Pole spear or Hawaain Sling in a separate category. "Recreational" spearfishing is just that, recreation & does not qualify as a world record. Fish speared on SCUBA fall under the "all-tackle" record keeping. Check out the list, you might know someone.
