Roundscale Spearfish

Atlantic Ocean and Mediterranean Sea — one of the rarest and most recently recognized billfish species. Only formally recognized as distinct from Longbill Spearfish in 2006 through genetic analysis. Found throughout the Atlantic but rarely positively identified by anglers.

68°F–80°F. An offshore blue water species found at temperature breaks and current edges. Habitat similar to other spearfish species.

Best Lures: Small to medium skirted trolling lures produce incidental catches. Small rigged ballyhoo at trolling speed are effective. Best Baits: Small rigged ballyhoo are most likely to produce. Small whole squid work well. Most catches are accidental — positive identification requires careful examination of scale structure.

Similar to Longbill Spearfish — typically 20–40 lbs. Distinguished by rounder scales visible under magnification. World record: 49 lbs 8 oz. Most fish are caught incidentally while targeting Blue Marlin and Sailfish.
