Abstract

This study updates the introduction of non-native fishes Nannostomus beckfordi, Aphyocharax anisitsi, Knodus moenkhausii, Moenkhausia costae, Ancistrus multispinis and Astronotus ocellatus in the largest ornamental aquaculture center located in Paraíba do Sul River basin, state of Minas Gerais, Brazil. There is evidence that all species are established and that some are spreading to a reservoir in the region. Management actions such as awareness campaigns to educate fish farmers and the inspection of fish farms carried out by IBAMA officials are suggested to avoid new introductions and spread.
