A well established population of the Atlantic blue crab Callinectes sapidus (Rathbun, 1896) in the English Channel?

In October 2017 and February 2018, two ovigerous females of Callinectes sapidus were collected in the Bay of Seine, Normandy. Occurrences of ovigerous females of the blue crab at different localities of the bay suggest that the population is well established in the English Channel.
