| Abstract: | Risk of establishment of the freshwater climbing perch (Anabas testudineus) in mainland
Queensland from the Torres Strait is high. The species is dispersed through human
assistance and/or attributes that assist its own spread. The species has the potential to
out-compete native freshwater and estuarine species, and has sharp well-developed gill
plates and spines that may choke and kill predatory species like barramundi if swallowed.
The presence of climbing perch would severely impact Queensland’s inshore and
freshwater fisheries, both commercial and recreational. The net present value of
expected lost fishing activity due to build-up of the climbing perch is $48.5 million when
the probability of introduction is 20 per cent. Analysis of potential spending on an entry
prevention strategy for the climbing perch can be justified, with a benefit cost ratio of
150 to 1. |
