- There are no formal stock assessments for king threadfin in NT or WA, although it is a key species caught in the NT barramundi fishery. Catches are stable in both jurisdictions and there are no immediate sustainability concerns.
- The NT and WA fisheries interact with threatened species, such as crocodiles and sawfish. Interactions are not thought to be resulting in population declines and area closures and marine parks should confer protection to endangered species.
- Independent observer coverage is due to begin again in 2018 in NT. It is non-existent in WA, a major concern offset by the small scale of this fishery .
- NT Barramundi Fishery (296t 2016)
- WA Kimberley Gillnet and King Threadfin Fishery (25t of king and blue threadfin in 2015)
There are no formal stock assessments for king threadfin stocks in NT or WA, although they are a key species caught in the NT barramundi fishery. The NT monitors the stock health of king threadfin by assessing long-term catch records and the age and length of fish caught over time to ensure these measures remain stable. The WA fishery lands a relatively small volume of king threadfin.
Threatened species caught in the NT and WA fisheries include crocodiles and sawfish. The NT fishing industry has developed a Code of Practice that details the best methods to release bycatch alive. Given the wide distribution of the protected species caught and the moderate interaction rates recorded previously by independent observers, there are no indications that the fisheries are causing population declines of any protected species. There are extensive areas closed to gillnet fishing in NT waters and recently established marine parks in WA that are likely to confer a degree of protection to endangered species.
There has been previous independent observer coverage in NT, where the program is due to begin again in 2018. There is no observer coverage in WA, which is a concern offset by the small scale of this fishery.
