Abstract: Exotic (introduced) species are a growing problem in ports worldwide and comprise the most important impacts in marine ecosystems. Periodic monitoring to detect introduced species is extremely important for effective population control. Here we sampled ascidian species near the port of Paranaguá for a taxonomic study of this fauna to attempt to detect introduced species. Larval stages in ascidians are short-lived, and dispersal is restricted to small distances, and so ascidians are very good bioindicators for … Show more

“…While S. plicata and A. sydneiensis are already known from Brazil as introduced species (ROCHA & KREMER 2005, LOPES 2009), the colonial P. aurantium must be considered a new introduction in Brazil. This species has never been seen in Brazil nor reported from any other place in the western Atlantic Ocean.…”

“…The first record of S. plicata in Brazil is from the 1800s (TRAUSTEDT 1883). Along the southern coast, S. plicata is usually found in anthropic environments on artificial substrates (MAYER- PINTO & JUNQUEIRA 2003, ROCHA & KREMER 2005, BARROS et al 2009). In Algeciras Bay, southern Spain, S. plicata was found as much on artificial as on natural substrates, but only in areas that had suffered some human impact (NARANJO et al 1996, CARBALLO & NARANJO 2002.…”

“…This suggests that D. perlucidum is introduced. Botrylloides nigrum Herdman, 1886, another new record for Currais MPA, is considered cryptogenic, but its occurrence on anthropogenic substrates (Rocha & Kremer 2005, Marques et al 2013) and a new molecular study of global populations (Sheets et al 2016) suggest that this is also an introduced species in southern Brazil. Symplegma rubra Monniot, 1972 was recorded only within the Paranaguá Estuarine Complex before 2005 (Rocha & Kremer 2005), yet now it is common in Currais MPA.…”

Symplegma rubra Monniot, 1972 was recorded only within the Paranaguá Estuarine Complex before 2005 (Rocha & Kremer 2005), yet now it is common in Currais MPA. As S. rubra is quite easily encountered and identified, by the large, brightly colored, colonies (Figure 5h), it is unlikely that, if present, it would have passed unnoticed in the 2002/2003 ascidian inventory (Rocha & Faria 2005).…”
