A total of 806 non-native ornamental fish species are (at the time of this study) contained in the grey list of potentially noxious fish species in Australia. As part of the national strategy, all species on the grey list are to be allocated a potential preliminary risk rating. Of the 806 species a total of 681 grey listed species have already been reviewed using the BRS Grey List Review methodology.
The aim of the present project was to populate the review matrix for the remaining 125 non-native ornamental grey listed fish species using the BRS Grey List Review methodology. For each species a total risk score was allocated using the review matrix provided by PIRSA.
Of the remaining 125 non-native ornamental fish species, 18 species (14.4%) were allocated an overall ‘low risk’ score, 25 species (20%) were ‘Borderline’ and 82 species (65.6%) were allocated a ‘high risk’ score. The ‘high risk’ species will be undergoing closer examination by the Ornamental Fish Management and Implementation Group (OFMIG), and will be assessed as to whether they are to undergo a rigorous risk assessment (RA). Such RA is essential to more robulstly identify the ecological and economical risk associated with the respective species and the potential implications for native Australian ecosystems.
