The blue crabs that were brought to Turkey for their economic value and released in lagoons in the Northern Aegean and the Saros Bay reproduced and multiplied. However, probably because they were not able to find the natural conditions they required in this region, they migrated to the Southern Aegean and inhabited the Güllük and Dalyan lagoons, extending right over to the Karadeniz fish trap in Taşucu. Today a large number of blue crabs are hunted in the Dalyan delta and are served by restaurants with various sauces and cooking methods.
