Introduction of the armored catfish, Pterygoplichthys ambrosettii (Holmberg, 1893), in a large effluent of the Upper Parana River basin

Distribution of non‐native suckermouth armoured catfish Pterygoplichthys ambrosettii in the upper Paraná River basin, Brazil

“…and Table ). The first record, noted in 2001, was from the Tietê River (Maruyama et al, ), in 2002 from the Paranapanema River (Garcia et al, ), in 2004 from the Grande River (Castagnolli, ) and in 2006 from the Paraná (Andrade et al, ) and Paranaíba rivers (Marçal, ) (Fig. and Table ).…”

Invasion characteristics ofPterygoplichthys ambrosettii(Holmberg, 1893) in the lower Paranapanema River, Brazil

“…The rate of invasion and their movement through the catchments is documented in full in Garcia et al. (), who suggested that studies on their biology and ecology be required between their invasive and natural ranges in order to help evaluate their dispersion and the associated consequences. Consequently, the aim of this study was to assess their weight‐length relationship and condition between their invasive and introduced ranges to identify whether these metrics indicated advantageous conditions in the extended range.…”

“…Non-indigenous to the upper Paran a River, it was able to disperse there as a consequence of flooding of the geographical barrier of the Sete Quedas waterfalls following construction of the Itaipu hydroelectric power plant (Grac ßa and Pavanelli, 2007). It was also able to reach the tributary rivers of the Tibagi and Cinzas rivers, which are tributaries of the lower Paranapanema River basin, through removal of fish specimens from the hydroelectric turbines and their release upstream the dams (Garcia et al, 2011) and/or through the release of samples cultured for ornamental aquaria (Magalhães and Jacobi, 2008). The rate of invasion and their movement through the catchments is documented in full in Garcia et al (2011), who suggested that studies on their biology and ecology be required between their invasive and natural ranges in order to help evaluate their dispersion and the associated consequences.…”

Presence of prohibited fishes in the Brazilian aquarium trade: effectiveness of laws, management options and future prospects

“…the yellow angelfish Centropyge heraldi (Woods and Schultz 1953))], and lack of awareness of these laws by persons involved in the aquarium trade. Prevention of introductions is the first, and most cost‐effective, management option to the Brazilian aquarium trade (Garcia et al., ; Abilhoa et al., ). Thus, it is imperative for IBAMA officials to enforce Federal Laws No.…”
