There is no commercial fishery for giant seabass, as the species is listed as “Critically Endangered” by the IUCN and all landings are from incidental take. Landings have been variable in the two decades between 1996 and 2015, fluctuating between 1 mt/yr and 4 mt/yr. Both exports and the value to the commercial fishery is considered negligible, with the value estimated at $12,600/yr. Stock status is critical and both abundance and mortality considered high concern, while bycatch impacts on humpback whales and white sharks are also a high concern. Conservation measures are thought to be moderately effective, but benchmarks are needed to assess the fishery’s impacts on the giant seabass population. Habitat impacts are minimal and while no spatial management or other policies to protect ecosystem functioning are currently in place, a multi-species, ecosystem-based management approach is in development.
