“…We argue that the absence of previous records in the Tramandaí river basin and the current establishment of artificial channels connecting the Laguna dos Patos and Tramandaí basin corroborate the hypothesis that this area may be the invasion pathway not only for P. iheringii, but probably for other previously recorded invasive species (Schifino et al, 2004;Artioli and Maia, 2010;Artioli et al, 2013). This inter-basin connection has been facilitated by local landscape characteristics, such as low terrain and large wetland areas, which allowed the development of rice fields and their associated network of artificial water channels (Becker et al, 2007), increasing the connectivity between two aquatic ecoregions (the Laguna dos Patos and Tramandaí-Mampituba).…”

“…The presence of nonnative fish species has been reported in the Tramandaí river basin (Schifino et al, 2004;Artioli and Maia 2010;Artioli et al, 2013), but their introduction pathway in the Tramandaí river basin is unknown. A plausible possibility points to the artificial water channels in the wetlands and rice fields at the watershed divide between the Laguna dos Patos basin and the Tramandaí river basin.…”

“…Firstly, because the natural occurrence of this species in the Tramandaí river basin is implausible. Although P. iheringii is widely distributed in the Paraguay-Paraná, Uruguay and Laguna dos Patos basins (Friel, 2008) it had never been previously recorded at the Tramandaí basin, despite large sampling effort since the 1980 decade (Malabarba and Isaia, 1992;Ramos and Vieira, 2001;Schifino et al, 2004;Rocha and Hartz, 2013;Malabarba et al, 2013;Guimarães et al, 2014). Additionaly, recent inventories of fish communities have recorded P. iheringii in the Laguna dos Patos system just next to the inter-basin connection with the Tramandaí system (in lake Casamento and neighboring wetlands; Becker et al, 2007), but not in the Tramandaí system, despite widespread sampling (Guimarães et al, 2014) and historical fish composition reviews (Malabarba and Isaia, 1992;Malabarba et al, 2013).…”

“…The limnic enviroments of Marinheiros Island house an ichthyofaunistic diversity within the range observed for lotic systems in southernmost Brazilian coastal plain, which is between 22 (Fortaleza lagoon; Schifino et al, 2004) and 67 species (Peixe lagoon; Loebmann & Vieira 2005). It is clear the taxonomic and numerical dominance of order Characiformes, with family Characidae encompassing around 46% of the species richness and 75% of all specimens collected.…”

Abstract:Marinheiros is the largest island of the estuarine archipelago of Patos lagoon and is considered an area of biological relevance in the coastal region of the extreme south of Brazil. Aiming to contribute to the knowledge on the biodiversity of this important area, we conducted an ichthyofaunistic inventory in the limnic environments of the island. Twenty-seven field trips were performed between April 2015 and May 2017. A total of 12 sites representative of habitats of an intermittent shallow lagoon, intermittent pools and a perennial artificial channel were sampled. Sampling of 2,436 specimens revealed the occurrence of 30 species, including the non-native piscivorous Acestrorhynchus pantaneiro. Characiformes was the most diverse order (18 species), followed by Cichliformes (four species) and Cyprinodontiformes (three species). Characiformes was also the most numerically abundant order (77%) followed by Cichliformes (17.6%) and Cyprinodontiformes (5.1%). The species richness recorded in Marinheiros Island is is comparable to the richness observed for lotic systems of southernmost Brazilian coastal plain. The fish assemblage is composed mainly of species of limnic habits whereas few taxa of estuarine-marine-limnic and estuarine-limnic habits were recorded. In view of the presence of allochtonous A. pantaneiro and its potential to impact native species, monitoring is recommended to the ichthyofauna of Marinheiros Island and the other estuarine islands, as well as peninsular systems connected to Patos lagoon estuary.

Com o objetivo de contribuir para o conhecimento sobre a biodiversidade desta importante área, realizamos um inventário ictiofaunístico nos ambientes limnicos da ilha. Vinte e sete visitas foram realizadas entre abril de 2015 e maio de 2017. Um total de 12 locais representativos dos habitats de uma lagoa rasa intermitente, poções intermitentes e um canal artificial perene foram amostrados. A amostragem de 2.436 espécimes revelou a ocorrência de 30 espécies, incluindo o piscívoro não-nativo Acestrorhynchus pantaneiro. Characiformes foi a ordem mais diversa (18 espécies), seguido por Cichliformes (quatro espécies) e Cyprinodontiformes (três espécies). Characiformes foi também a ordem mais numericamente abundante (77%), seguida po Cichliformes (17,6%) e Cyprinodontiformes (5,1%). A riqueza de espécies registrada na Ilha dos Marinheiros é comparável à riqueza observada para sistemas lóticos da planície costeira do extremo sul do Brasil. A assembleia de peixes é composta principalmente por espécies de hábitos límnicos, enquanto que poucos taxa de hábitos estuarino-marinho-límnico e estuarino-límnico foram registrados.

“…A good example of this is the coexistence between A. bimaculatus and A. fasciatus in the reservoir, both abundant during the dry seasons. The abundance and coexistence of these two species was also observed by Hoffmann et al (2005), Galetti Junior et al (1990), Agostinho et al (1997aAgostinho et al ( ,1997b, Schifino et al (2004) and Teixeira et al (2005).…”

To determine the fish species present in Taperoá II Reservoir, and their relevance to the local economy, this research aimed to evaluate the composition, abundance, degree of dominance and constancy of species, along with diversity, richness, evenness and similarity indices in a tropical semi-arid fish assemblage, during one year. Six 24 hour-long samplings were carried out between October 2005 and October 2006 using cast, seine and gillnets. The 889 collected individuals belonged to 11 species from 9 families. Temporal variation was observed in the capture frequency of different species, and a significant negative correlation between precipitation and number of individuals was also observed. Among the recorded families, Characidae showed a higher frequency of occurrence (38.4%), mostly due to Astyanax bimaculatus (Linnaeus, 1758) and A. fasciatus (Cuvier, 1819). Eight species were categorised as constant, two as accessory and one as accidental. Diversity index values were intermediate with low fluctuation throughout the study period, and no correlation with precipitation or water volume. However, the greatest diversity value was recorded in March 2006, when the peak of the precipitation was recorded. Evenness values showed a similar trend to the diversity index.Keywords: reservoir, ecology, community, temporal variation. Diversidade da ictiofauna do açude Taperoá II, semiárido paraibano, Brasil ResumoPara determinar as espécies de peixe presentes no Açude Taperoá II e sua relevância para a economia local, objetivou-se determinar a composição, a abundância, a dominância e a constância de espécies da ictiofauna, bem como os índices de diversidade (H'), riqueza, equitabilidade e similaridade de espécies ao longo de um ano. Foram realizadas seis coletas ao longo de 24 horas, de outubro de 2005 a outubro de 2006, utilizando-se tarrafas, redes de espera e arrasto. Foram coletados 889 indivíduos, identificados em 11 táxons específicos, distribuídos em nove famílias. A abundância das diferentes espécies variou temporalmente, com correlação negativa significativa entre a precipitação e o número de indivíduos. Dentre as famílias identificadas, Characidae apresentou a maior frequência de ocorrência (38,5%), representada pelas espécies Astyanax bimaculatus (Linnaeus, 1758) e A. fasciatus (Cuvier, 1819). Oito espécies foram consideradas constantes, duas acessórias e uma acidental. O índice de diversidade apresentou valores entre 2,11 e 2,80, e não apresentou correlação com a precipitação e o volume do açude. Entretanto, o índice de diversidade mais elevado foi registrado no mês de março de 2006, pico do período chuvoso. Os valores da equitabilidade comportaram-se de forma semelhante aos do índice de diversidade.Palavras-chave: reservatório, ecologia, comunidade, variação temporal.
