TORRES, Pablo Javier  y  GONZALEZ-PISANI, Ximena. Primer registro del cangrejo verde, Carcinusmaenas (Linnaeus, 1758), en Golfo Nuevo, Argentina: un nuevo límite norte de distribución en costas patagónicas. Ecol. austral [online]. 2016, vol.26, n.2, pp.134-137. ISSN 1667-782X.

This note was aimed at reporting the presence of the "European green crab" Carcinus maenas in the coast of Nuevo Gulf (Chubut, Argentina). This new record extends the actual distribution range of this species 250 km to the north of San Jorge Gulf, where it was previously reported. C. maenas is one of the most successful aquatic invaders in the world, with populations established on all continents, and represents a threat to the integrity of coastal ecosystems of southern South America, and also to the economies of fshing communities of South Atlantic.
