A tagging experiment of the blue and red shrimp, Aristeus antennatus was carried out in the Ionian Sea, off Roccella Jonica (RC). The experiment involved 45 shrimps, caught by trawling at night at about 100-150 m in depth. One month after tagging one specimen was recaptured at about 10 nautical miles from the releasing point. As the first case of tagged recaptured deep sea shrimp, this experiment brings important results about the feasibility of experimental studies on displacement and growth and gives the first direct proof of the migratory abilities A. antennatus.
