Cero Mackerel Fishing Guide

The cero (Scomberomorus regalis) is the rarest and most tropical of the three US Atlantic mackerel species, found primarily in the crystal-clear waters of the Florida Keys and Bahamas. Unlike Spanish mackerel (which have oval spots only) and king mackerel (which lacks spots entirely), cero have both a pattern of yellow-orange spots below the lateral line AND a distinctive yellow-to-orange horizontal stripe running mid-body. They are associated with clear-water coral reef environments rather than the turbid nearshore waters preferred by Spanish mackerel. Cero rarely appear north of Miami in meaningful numbers — the Keys and Bahamas represent the core US range. They are considered finer eating than Spanish mackerel, with slightly firmer flesh.

Cero Mackerel is a saltwater species.

Habitat

Clear tropical waters over coral reefs of the Florida Keys, southern Florida Atlantic coast, and Bahamas; occasionally ranging north to about Palm Beach in warm months. More reef-oriented than Spanish mackerel — found at the edges of coral formations and over reef structure rather than in inlets or turbid nearshore water.

Diet

Small reef fish, anchovies, and squid. Caught by trolling small lures along reef edges or slow-trolling live pilchards near the reef edge — the same techniques used for Spanish mackerel but in cleaner, deeper water.

Fishing Techniques

• Trolling silver spoons near reefs
• Casting small jigs to surface schools
• Live pilchards near structure
