King mackerel basics

King mackerel (Scomberomorus cavalla) is a long, fast pelagic with a lateral line that drops sharply toward the tail, a gray-blue back, and a mouth built for sardines—not the compact spots of a Spanish. Jacks, bluefish, and cobia are different silhouettes; when in doubt, let the fish go and re-read a diagram, not a dock rumor.

Troll passes, planers, and wire

  • Speeds and spread depths that match a bigger bait class than Spanish trolling; wire or single-strand leaders where tooth wear is a pattern.
  • Chaos discipline on a six-pack: who clears which rod when a hot fish crosses the rigger— agree before the strike, not during it.
  • Bycatch with tunas, cobia, and sharks in the same water column: species ID and HMS tags are not optional extras for serious offshore crew.
