Ballast water seems to be the most likely means of transferring this species, or its eggs between coastal waters of different continents. The fact that A. tonsa can produce highly resistant diapause eggs as well as eggs that can be induced into quiescence has probably played an important role for its wide distribution. [details]

Unreviewed
Alien species Prior to its introduction in Europe Acartia (Acanthacartia) tonsa only occurred in the Indo-Pacific region. The exact origin of the species however remains unknown. This small crustacean came to Europe through transport in ballast water of ships and in 1916, a first European observation was reported. In 1952 the species was found in the Sea Scheldt, a first mentioning of A. tonsa for our region. Later, in the sixties, the species was found in the Ostend Sluice Dock. Salty as well as brackish areas serve as its habitat and this alien species can compete with indigenous plankton species. [details]Habitat Known from seamounts and knolls [details]
