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.
Highlights
The intentional or unintentional introduction of aquatic non-native species is increasing around the globe (Lockwood et al 2007)
A new phase is in progress unleashed by greater demand for aquarium trade (Magalhães and Jacobi 2016)
Samples and interviews with fish farmers, the natural spread of the non-native species, especially N. beckfordi, K. moenkhausii, M. costae and A. multispinis occurred in the same year via unintentional escapes of production ponds, introduction into creeks and arrival in the Glória reservoir
