摘要：Ports of big coastal cities are exposed to exotic species as a consequence of shipping traffic. As the Port of Recife receives an annual average of 491 ships from other regions of Brazil and from all over the world, this work was aimed at knowing which marine animals were passively transported on such vessels hulls, in order to map and monitor new bioinvasions in the area. Thus, 32 vessels of several origins were investigated between November 2005 and March 2006, samples were taken and the macrofauna identified. Sixty species of associated animals were identified, consisting of 28 sessile species, particularly the Cirripedia Balanomorpha and Lepadomorpha as dominants, 8 sedentary animals, namely Mytillidae and Dreissenidae and 23 free-living species, particularly, Caprellidae, Gammaridae, Tanaidacea, Turbellaria, Nemertea and Polychaeta. The first occurrence of Conchoderma virgatum was recorded with exact location for the Brazilian littoral, and Conchoderma auritum, Amphibalanus subalbidus and Haliplanella lineata were recorded for the first time at the littoral of Pernambuco State. The invasion pathway was confirmed for Amphibalanus reticulatus and Mytilopsis leucophaeta, invader species of the estuarine area of Recife's city. Megabalanus coccopoma was considered as a risk invader species for the region.
