Native, Non-Native and Invasive Species of Ornamental Fish Traded in Kupang, East Nusa Tenggara

Inter-country sales of ornamental fishes are one of the ways non-native and invasive fishes enter an aquatic ecosystem. This contributes greatly to the distribution and abundance of native fishes in the aquatic ecosystem. The aim of this study is to collect and identify quantitative baseline data on some information of ornamental fish species sold in ornamental fish shops in Kupang City. Results showed that there were 46 species recorded during the study and only 20% (n=9) of the species were native Indonesian species and 80% (n=36) of the species were non-native (1 hybrid species). In addition, it was recorded that 7% (n=3) of the total fish sold in Kupang City were invasive species. The invasive species were Carassius auratus, Xiphophorus helleri and Poecilia reticulata. These three species are included in the 80% non-native species.
