Seasonal behaviour

Moves closer to the coasts for spawning in spring, then migrates to deeper waters in summer.

Juveniles

When to catch Atlantic mackerel

This species shows peak fishing activity in summer and autumn, when the productivity index (FPI) reaches its highest values.

Fishing activity decreases in winter, when conditions are less favourable.

How to really catch it

The Atlantic mackerel is a true pelagic fish: streamlined body, deeply forked tail, and a life spent schooling in open water. When a feeding shoal pushes close to shore, everything speeds up and the fishing turns dynamic, visual, almost electric; understanding that rhythm is the key to catching it consistently.

🐟 Good to know

An important biological trait of mackerel is its pelagic spawning: the eggs are transparent and light, remaining suspended in the water column instead of sticking to the bottom. The larvae are planktonic as well and develop in nutrient-rich areas, fully consistent with the species’ pelagic way of life.

🌊 Where & when

You find it in the North Atlantic and the Mediterranean, from coastal waters to offshore, over sandy areas or near reefs, from the surface down to 200 meters. In spring it moves closer to the coast to spawn, between 20 and 60 meters; then in summer it shifts into deeper offshore water, while the most favorable period remains from June to November.

🎣 How to really catch it

To really catch it, the most practical approach is feathering rigs or fast spinning with small metal lures and imitation baitfish, retrieved steadily to mimic fleeing anchovies and sardines. Use a medium-light spinning rod, 8-10 lb line, a 12-15 lb fluorocarbon leader and, when needed, light split shot or sinkers to keep the lure in the depth band where the school is moving.

💡 The detail that makes the difference

The soundest tip is to look for school activity in open water near the coast and avoid staying too long on one fixed spot: mackerel is a diurnal predator that moves in large groups and feeds at speed. When you intercept a passing school, getting a compact moving lure in front of it matters more than a complicated rig.

Catch & handling tips

Fight

Feisty, but tires quickly once hooked.

Handling

Handle carefully to avoid removing scales and use a moist cloth.

Release

Release quickly back into the water, preferably without removing it from the water.
