King Mackerel (Kingfish)

Category: Nearshore

Trip Type: Nearshore / Offshore

King mackerel are fast, aggressive predators known for explosive strikes, blistering runs, and action-packed fishing.

Appearance

King mackerel, commonly known as kingfish, are sleek, fast-swimming predators with olive-green to bluish backs that fade into bright silver sides and a white belly. They have two dorsal fins, with the first often folded into a groove along the back. Their streamlined bodies and razor-sharp teeth are perfectly designed for chasing down baitfish at high speed.

Habitat

King mackerel are commonly found in nearshore and offshore waters throughout the Gulf of Mexico. They often patrol reefs, oil platforms, bait schools, shipping channels, and coastal structure in depths ranging from 40 to 150 feet. Larger fish are frequently encountered near oil platforms, passes, and areas with abundant bait.

Average Size

Most king mackerel caught in Louisiana waters weigh between 10 and 30 pounds, although fish exceeding 40 pounds are considered trophies. Exceptional fish can surpass 70 pounds.

Best Time to Catch

King mackerel are most commonly targeted during the warmer months when water temperatures rise and baitfish become abundant along the Louisiana coast.

Fishing Tips

Drifting and trolling are among the most effective techniques for king mackerel. Live bait, strip baits, spoons, jigs, and trolling lures all produce fish. Menhaden, squid, and shrimp can be effective natural baits. Chumming can help attract schools and increase action, especially around structure and bait concentrations.

Louisiana State Record

82 pounds — caught by W. D. Lamb in 1980. This impressive fish remains Louisiana’s state-record king mackerel and demonstrates the trophy potential of Gulf kingfish.

Fun Fact

King mackerel are capable of bursts of speed exceeding 40 mph, making them one of the fastest predators commonly encountered in Gulf waters.
