Landing 100+ kilograms of bluefin tuna in the Almadraba, an ancient method of catching tuna in nets as they migrate from the Atlantic Ocean into the Mediterranean to breed. Today's catch was 80 bluefin tuna, selling for €16 per kilogram, primarily as sushi for the Japanese market. This fishing technique was developed by the Phoenicians and consists of a labyrinth of bottom-anchored nets which trap the migrating fish before they are speared by divers in the final chamber. Atlantic bluefin tuna were heavily overfished, but a quota system was established in 1998, and the species has started to make a comeback. The Almadrabas act as a way for scientists to monitor the size of the population.
