The arrival of the american blue crab, callinectes sapidus rathbun, 1896 (Decapoda: Brachyura: Portunidae), in the gulf of lions (mediterranean sea)

Abstract

After reaching the Italian and Spanish coasts of the Western Mediterranean Sea, the American blue crab Callinectes sapidus was finally observed on the French coasts. To date, it has been caught in eleven lagoons and three sites of the French coast. Its strong invasion capacities will probably lead to important changes in the structure and composition of French lagoon biota.
