Ornamental exotic fish introduced into Atlantic Forest water bodies, Brazil
Specimens of Puntius arulius, P. ticto, P. titteya, P. oligolepis, Nannostomus beckfordi, Poecilia latipinna, P. velifera, Trichogaster pectoralis, and Betta splendens were recorded in the largest ornamental aquaculture center in Brazil. These fishes were introduced in the study sites by accidental escape and intentional release. There is evidence that six species are reproducing. Measures are proposed to prevent further spread of ornamental exotic fishes in the region.Key words: Brazil, species introduction, exotic fishes, ornamental aquaculture.
