Abstract:

Indonesia is one of the biggest worldwide suppliers and has been in the industry for a long time. Nonetheless, the information about both marine and freshwater species traded as ornamentals is lacking. This study aims to provide a list of freshwater and marine species exported from Indonesia, assess the risk of invasiveness in selected non-native iconic species, and to form suggestions for sustainable use of the traded species.The list of species was obtained directly from Indonesian exporters. Additional data such as species conservation status and distributions were derived from qualified databases. Several non-native popular species were chosen for further analysis. Climate suitability was analysed using CLIMATCH 1.0. The Fish Invasiveness Screening Kit (FISK) was adopted for all selected species within Indonesia as Target Region.The study found 1323 of total species exported as ornamental from Indonesia consisted of 773 marine species and 550 freshwater species. The biggest portion of the species came from class Actinopterygii. Additionally, several species of elasmobranch, invertebrates, and amphibians were also found to be traded. Four non-native iconic species were chosen to be assessed. Betta splendens was assessed to be a high-risk species in Target Region. Meanwhile, Paracheirodon innesi, Poecilia reticulata, and Pterophyllum scalare were rated as medium-risk species.Betta splendens was found to have been established in Indonesian water. Most probably due to its widespread use as a mosquito bio-control agent. The utilisation of native Indonesian species for bio-control is highly recommended. Additionally, eco-certification should also be considered to protect and conserve the endemic and or endangered Indonesian species.
