Before tourism, before the highways, before the first holiday apartment was built, the Algarve was a coast of fishermen. Its identity — its food, its architecture, its language — was shaped by generations who made their living from the Atlantic. Much of that tradition has faded, but enough survives that a curious visitor can still see, taste, and even join it for a day.

Here’s the story, and how to experience it now.

A Working Coast Long Before a Tourist One

The Algarve coast has been fished continuously for more than 2,000 years. Phoenician and Carthaginian traders salted fish here in the 8th century BCE. The Romans built industrial-scale fish-salting plants along the coast — you can still see the ruins of one in Quarteira — to supply garum, a fermented fish sauce that was the Roman Empire’s ketchup.

When the Moors ruled southern Iberia between the 8th and 13th centuries, the fishing culture layered on more techniques: fixed traps, inshore netting, preservation methods that still echo in modern Portuguese cuisine. Many Algarve place names (Albufeira, Alcoutim, Algoz) are Arabic in origin, a reminder that this coastal culture is centuries older than Portugal itself.

By the 18th and 19th centuries, the Algarve’s fishing economy had stabilised around three pillars: sardines, tuna, and octopus. Each had its own traditions, its own season, and its own communities.

The Tuna Almadrabas

The most dramatic tradition was the almadraba — a massive fixed fishing trap used to catch migrating bluefin tuna. Giant nets were suspended between anchored boats along the coast, funneling tuna into a central chamber where they were caught by hand.

Tuna almadrabas were a summer event: dangerous, spectacular, and economically enormous. Whole villages turned out. The technique arrived via the Moors and Sicily and continued into the 20th century. The last commercial almadraba on the Algarve coast closed in the 1970s, a casualty of overfishing and modernisation, but you can still see its traces.

The town of Vila Real de Santo António and smaller villages like Olhão and Fuzeta all have tuna-trap heritage. The annual Tuna Festival in Olhão each August celebrates this history — if you’re in the area, go.

Sardines and Salt

The Algarve’s other big tradition, sardine fishing, was more modest but far more continuous. Small open boats (traineiras) would go out at night with oil lamps to attract the fish into surrounding purse seine nets. The catch was preserved with salt harvested from the coastal flats at Castro Marim, Tavira, and Olhão.

Sardine fishing still happens, though on a much smaller scale. The canning industry that built towns like Portimão and Vila Real de Santo António began in the late 19th century and peaked in the 1950s. Most of those canneries are now gone, but a handful survive and still produce some of the best tinned fish in the world — worth finding as a souvenir.

Grilled sardines (sardinhas assadas) are still the summer food of the Algarve. Eat them anywhere you smell charcoal and a crowd of locals between June and August. The traditional phrase is “sardinha em junho é peixe, sardinha em julho é sumo, sardinha em agosto é cuspo” — in June sardines are fish, in July juice, in August spit — meaning they’re fattest in early summer and past their prime by the end of it.

Octopus and Clay Pots

Of all Algarve fishing traditions, the one most alive today is octopus fishing with clay pots. It is an ancient technique — Roman writers mention it — that works beautifully: octopus instinctively seek out enclosed spaces to hide in, so a string of clay pots left on a sandy bottom overnight will fill up by morning.

The pots (alcatruzes) are lined up on the fishing boats you see in every small harbour. Go to the harbour in Sagres, Albufeira, Olhão, or Santa Luzia in the early morning and you’ll see them being unloaded, still glistening.

Santa Luzia, east of Tavira, has branded itself as “Portugal’s octopus capital” and does it earnestly — the whole village eats, cooks, and talks octopus. Arroz de polvo (octopus rice) and polvo à lagareiro (octopus with potatoes and olive oil) are local specialties worth a detour.

On our Reef Fishing Tour we often pass lines of octopus pot buoys, and can explain how the local operators manage their territory. Most fishermen you see in small boats at dawn are working octopus or setting up for the day’s haul of sea bream and sargo.

Pole-and-Line vs Industrial Trawling

One of the more hopeful trends in Algarve fishing is that the traditional small-scale fleets — open wooden boats, handlines, pots, day trips — are holding their own against industrial pressure. Portugal has some of the strongest small-boat fishing communities in Western Europe, and the Algarve is their heart.

If you walk the harbours of Olhão, Fuzeta, Quarteira, Culatra, or Ferragudo in the early morning, you’ll see the whole spectrum: pole-and-line boats coming in with mackerel and sea bream; octopus boats unloading pots; traditional flat-bottomed xávegas used in the lagoon; and yes, a few bigger trawlers.

The small-boat operations fish more sustainably, support more local jobs per kilo caught, and produce better-quality fish. Supporting them starts with eating at restaurants that source locally — ask “é peixe da costa?” (“is this coastal fish?”) and a good restaurant will tell you honestly.

Where to Experience It Today

A few places still offer a real connection to the fishing past:

  • Olhão Municipal Market (Saturdays) — the best coastal fish market on the south coast, right in the harbour
  • Santa Luzia — lunch at any restaurant that looks like a house on the waterfront
  • Culatra Island — a fishing community still living on a barrier island, reachable by local ferry from Olhão
  • Ferragudo harbour at dawn — small boats unloading; feels unchanged for decades
  • Fuzeta Tuesday market — broader than fish but a living version of village commerce

And from the water: any fishing tour gives you a direct experience of what it feels like to wait patiently for a sea bream on a handline, a rhythm that hasn’t changed much in a thousand years.

Why It Matters

Tourism is now the Algarve’s main industry. But fishing still shapes the coast — the harbours, the food, the language. A week here spent only in the beach clubs gives you one version of the region. A morning on a small boat with a skipper whose father and grandfather also worked these waters gives you another, quieter one.

Both are the Algarve. We’d argue the second one is worth making time for.

Keep Exploring

If this side of the coast interests you, pair a morning reef fishing tour with an afternoon visiting Olhão market. For those with more time, a day in the eastern Algarve — Tavira, Santa Luzia, Culatra Island — rounds out the picture. And when you come back for dinner, order the octopus.
