First occurrence of Callinectes sapidus (Rathbun, 1896) within the Sacca di Goro (Italy) and surroundings

The Sacca di Goro lagoon is an area located in the northern part of Italy. This locality has benefited in the past of an occasional and later the planned introduction of the Manila clam. Nowadays it produces more than 50% of the entire Italian clam production. Recently the crab Callinectes sapidus has been spotted and reported a few months ago on its female carrying eggs. This may signify the complete acclimation of this species in the Sacca di Goro lagoon and a potential ongoing spread to surrounding areas
