Almadraba (a Spanish word coming from ; in ) is an elaborate and ancient technique for trapping and catching Atlantic bluefin tuna (Thunnus thynnus).
The technique, in its most simple iteration, consists in setting up net barriers to trap the tuna when they migrate into the Mediterranean Sea from the Atlantic Ocean (February to July), on their way to spawn and
until recently, on their return journey, ("al revés"); the bycatch contains, among others, bullet tuna (auxis rochei), little tunny (euthynnus alletteratus), Atlantic bonito (sarda sarda), bigeye tuna (thunnus obesus) and swordfish (xiphias gladius).
