Expansion of the North Pacific Copepod Eurytemora Pacifica Sato, 1913 (copepoda: Calanoida: Temoridae) along the Atlantic Coast of France
BIOINVASIONS RECORDS(2016)
摘要
The North Pacific copepod Eurytemora pacifica Sato, 1913 was fortuitously found in a sea water tank of the Marinarium of Concarneau (Southern Brittany, France). The presence of ovigerous females in this tank as well as in some nearby ecosystems confirms the successful introduction of this species along the Atlantic coast of France. Morphology was examined using scanning electron microscopy and confirmed the species identity. The presence of two types of females resulting from cyclomorphosis was confirmed, as well as the production of two types of eggs. The French Atlantic coasts seem to be the only area in the world where the species has been reported as a non-indigenous species (NIS).
