John Dory: Quick Facts
Scientific name: Zeus faber

Ranking: D (Amber - Concerns)
Best Fish Guide: John Dory
Ranking: D (Amber - Concerns)
Description: John Dory are mid-water to seafloor dwelling and whilst found throughout New Zealand they are most common north of the Cook Strait. They are caught in mixed species trawl catches where the main target species are snapper and tarakihi, with some also caught by Danish seine.
Ecological concerns: The damage done by bottom-trawling, the unknown long-term sustainability of the catch limits, the unknown status of stocks, population size and stock trends (uncertainty around possible declines off the West Coast South Island) and the uncertainty about stock boundaries in relation to quota boundaries. Limited research and the lack of a management plan are also of concern.
Economic value: New Zealand market plus exports to Australia, United States and Germany with a value of about $5 million in 2008.
Best option: John dory caught by Danish seine rather than by trawl. Avoid fish caught using bottom trawl gear.
