When to catch Bluefin tuna

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

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

How to really catch it

The Atlantic bluefin tuna is the pure face of open water: a fusiform body, dark blue back, and power built for speed and for chasing bait schools in daylight. When it enters a feeding lane or cuts across a nutrient-rich current, everything changes pace: this is a fish that demands respect, technique, and composure.

🐟 Good to know

It is a pelagic fish that undertakes long transoceanic migrations between feeding and spawning areas. During the spawning season it releases highly buoyant pelagic eggs, while the larvae remain planktonic in surface waters, where they grow quickly.

🌊 Where & when

You find it in the Mediterranean and the Atlantic, mainly over open and deep water, often where currents concentrate nutrients and forage, including near submarine canyons and pelagic barriers. It approaches coasts in the warmer months to spawn, with peak presence in June, July, and August; in colder months it tends to remain offshore.

🎣 How to really catch it

If you want to fish for it for real, heavy trolling is the most concrete approach: work offshore along active currents and edges of lively water, presenting live fish, sardines, squid, or artificials with a stout trolling rod, high-strength line, and a very strong steel or fluorocarbon leader. Large hooks, including circle hooks, help manage a violent strike and a fight marked by deep runs.

💡 The detail that makes the difference

The most defensible tip is to think first about its food: anchovies, sardines, and mackerel. If you see chaotic surface activity or bait compressed by current, do not fish blindly in empty blue water; run your bait along the edge of the bait school, where a predator hunting in groups is more likely to intercept fleeing prey.

Catch & handling tips

Fight

Strong and powerful, fights and makes rapid deep dives.

Handling

Handle carefully to avoid muscle and fin damage.

Release

Release quickly to reduce stress and injury.
