Cero Mackerel

Overview

The cero, or cero mackerel, is a swift, streamlined mackerel of tropical Atlantic reefs, a close relative of the king and Spanish mackerel prized for its speed, its willingness to hit lures, and its fine table quality. A favorite of South Florida and Caribbean anglers.

Identification

Cero are steel-blue above and silver below with a distinctive bronze-yellow stripe down the midline plus rows of yellow spots above and below it. The solid lateral stripe with spots separates them from the spotted Spanish mackerel and the plain-sided king mackerel.

Range & Habitat

They range the warm western Atlantic from South Florida through the Caribbean, holding around reefs, wrecks and structure in clear tropical water.

Behavior & Diet

Cero are fast reef predators that chase small baitfish over and around structure, striking lures and baits hard and running fast when hooked.

Best Seasons

Caught year-round in tropical water, with warm months and clear conditions often best over the reefs.

How to Catch Them

Casting and trolling small shiny lures and live bait around reefs and wrecks, and drifting live pilchards; a light wire or heavy fluorocarbon leader guards against their teeth.

Tackle & Rigs

Light to medium spinning or conventional gear, 12-20 lb line, a short wire or heavy fluorocarbon leader, and small lures or live bait.

Landing, Handling & Release

Handle carefully around the sharp teeth; bleed and ice keepers immediately for the best flesh.

Table Quality

Cero are excellent - firm, mild and finer than king mackerel, superb fresh, grilled or as ceviche when bled and iced (the FDA's rule of thumb for raw fish is to use fish that has been previously frozen, which kills parasites though not all germs). The FDA's seafood hazards guide lists cero among the fish associated with ciguatera fish poisoning, a toxin of subtropical and tropical reef fish that cooking and freezing do not reliably eliminate; the risk depends on where the fish was caught, so heed local advisories.

Common Mistakes

Fishing without a bite leader and not chilling the catch promptly.

Regulations & Conservation

Managed with mackerel size and bag limits that vary by region. Confirm current federal and state regulations before keeping fish. We do not give legal advice.
