Dories have succulent, white, sweet and finely textured flesh.
They can be baked, grilled, barbecued, fried, steamed or poached.
Dory fillets are delicate and often best coated or wrapped in foil for cooking.
Scientific name: Zeus faber
Other names: St Peter’s fish
Description: John dory have highly compressed plate-like bodies with large heads and large mouths. They are silvery to olive-green, with a blue-black spot surrounded by a yellowish ring on each side of the body. John dory often also have darker, wavy lines on the body. The scales are very small. The fins are spiny and dusky coloured.
Size (length and weight): Up to about 65 cm in length and 3 kg. Commonly found at 30‑45 cm in length and 0.5‑1.5 kg. Females grow larger than males.
Life span: Up to 15 years. Females live longer than males.
Habitat: John dory are a demersal species that lives close to the sea bed in coastal and continental shelf waters. They can be found to depths of 200 metres. John dory are considered to have a locally patchy distribution and use a variety of habitats including open sand, muddy grounds, rock structures and reefs. John dory are generally solitary.
Prey: Fish, crustaceans, molluscs and occasionally cephalopods.
Predators: Sharks, large bony fish and potentially marine mammals such as dolphins.
Reproduction: John dory reach reproductive maturity at 3‑5 years of age. They are known to spawn off the coast of New South Wales in late summer and autumn. John dory spawn multiple times during the spawning season. Fecundity has not been estimated, but is thought to increase with body size.
Other notes: Known as kuparu in New Zealand.

Management of catch
John dory are predominantly caught incidentally using trawl and danish seine in the Commonwealth South East Trawl Sector.
The Commonwealth catch of John dory is managed by quota. This means the catch of this fish by commercial fishers is restricted by weight. AFMA also restricts the number of boats and the type and amount of gear that can be used to fish for John dory.
Commercial fishermen are required to fill in records of their catches, during each fishing trip and when they land their catch in a port. This helps us keep records of how much is being caught.
AFMA decide on the amount that can be caught each year from expert advice and recommendations from fisheries managers, industry members, scientist and researchers.
John dory are found from south eastern Queensland, around the south of the country, and north to the central coast of Western Australia, however most catch is taken off New South Wales and eastern Victoria.
They can be found year round from shallow inshore waters to a depth of about 400 metres.
Fishing gear and environmental impacts
Bottom trawl and danish seine are the main fishing method used to catch John dory.
The impact of bottom trawl on bycatch species and habitats has been assessed as part of the ecological risk assessments. AFMA mitigates, or reduces, that impact through its ecological risk management strategy. The strategy details a number of management arrangements and strategies which aim to reduce the impact of fishing on the environment, including:
- minimum mesh sizes for bottom trawls to reduce the catch of small and juvenile fish
- mitigation devices to reduce interactions with threatened, endangered and protected species
- and closing areas to fishing to protect vulnerable species and habitats.
All bottom trawl boats are also required to have a seabird management plan in place to reduce interactions with seabirds during fishing.
