What is the size limit for Spanish mackerel in Florida?

12 inches FORK length, with a daily bag of 15 per harvester and no closed season. Fork length is measured from the snout to the fork of the tail, not to the tip — and on a deeply forked fish like a Spanish that is a real difference. Most Florida species are measured by total length, which is exactly why this one is measured wrong so often. Checked with FWC on 29 August 2026.

What is the difference between fork length and total length?

Total length runs from the snout to the very tip of the tail. Fork length stops at the fork — the notch in the middle of the tail. On a Spanish mackerel, whose tail is deeply forked, a fish that is legal by total length can be undersized by fork length. Measure to the fork.

What is the best lure for Spanish mackerel?

A small silver casting spoon retrieved fast. Spanish hunt by speed and will refuse a bait moving slowly. Small jigs and straw rigs also work, and trolling small spoons behind planers covers water when the fish are scattered.

Do you need a wire leader for Spanish mackerel?

Something more than plain mono. Spanish have genuinely sharp teeth and cut light leader routinely. A short wire bite trace stops the losses outright; heavy fluorocarbon is the compromise most anglers make, trading some bite-offs for more strikes in clear water.

How do you find Spanish mackerel?

Look for birds. Spanish push bait to the surface and diving birds mark the school from a long way off. Failing that, work beaches, piers, passes and nearshore structure during the spring and autumn migrations.

How to Catch Spanish Mackerel in Florida

Spanish mackerel chase down a fast bait and refuse a slow one, so the retrieve is the technique. Two details catch people out: they cut straight through mono leader, and Florida measures them by fork length rather than total length, which is not how most other species there are measured.

Retrieve faster than feels sensible. Spanish mackerel hunt by running bait down, and a lure moving slowly reads as wrong to them — the single most common reason people fish over a school and catch nothing.

Two details separate anglers who do well from anglers who lose tackle and keep undersized fish.

They are measured by fork length, not total length


Minimum size	12 in FORK length
Daily bag	15 per harvester
Season	Open year-round
Legal gear	Hook and line, cast net, beach or haul seine, spear

Fork length is measured from the snout to the fork of the tail — the notch — not to the tip. Most Florida species are regulated by total length, so the habit almost everyone brings to the ruler is the wrong one here. On a fish with a tail as deeply forked as a Spanish, that difference is real: a mackerel that measures 12 inches to the tail tip can be under 12 to the fork, and undersized.

They cut through mono

Spanish have small, genuinely sharp teeth and they cut light leader as a matter of routine. If you fish a session without a bite trace you will lose lures — not occasionally, but repeatedly, and usually the one that was working.

A short wire bite trace stops it outright. Heavy fluorocarbon is the compromise most anglers make, trading some bite-offs for more strikes in clear water. Either is better than tying a spoon straight to light mono.

Finding them: look up

Spanish push bait to the surface, and diving birds mark the school from a mile away. That is the most efficient way to find them, and it is why a pair of binoculars earns its place.

Failing birds: beaches, piers, passes and nearshore structure, during the spring and autumn migrations when schools move along the coast with the water temperature.

Tackle and retrieve

A small silver casting spoon, retrieved fast, is the standard and still the best starting point. Small jigs work. Trolling small spoons behind planers covers water when fish are scattered rather than schooled. Our saltwater lure guide covers metal jigs suited to this kind of fast, flashy presentation.

The retrieve is not a subtlety. If you are catching nothing over a school, wind faster before you change lures.

Spanish are also very good eating, and better still if bled and iced immediately — as with any oily fish, what you do in the first ten minutes matters more than anything later. See how to fillet a fish.
