Uses: gamefish: yes;
Comments: Occurs in continental shelf waters from Moreton Bay in Queensland to Cape Cuvier in Western Australia. Commercial fishery: John dory are taken primarily as a bycatch of the South East Fishery, although from shallower grounds than the mirror dory fishery. John dory are trawled from depths between 50 m and 200 m off New South Wales and eastern Victoria. Catches of John dory from the South East Fishery showed little variation between 1985-86 and 1989-90, ranging from 180 t to 270 t. John dory are also commonly caught by Danish vessels in Victorian waters and occasionally by haul seines in bays and estuaries. John dory are sold on the domestic fresh fish market as whole fish. Recreational fishery: In estuaries and bays, John dory are often caught by anglers using live fish baits, and on onshore reefs, anglers may catch this species using whole fish or flesh baits (Ref. 27128). The Australian Anglers Association record for John dory is 2,950 g and was recorded from New South Wales in 1974. Resource status: The catch history for John dory has shown little variation and catch levels as of 1993 seem to be sustainable (Ref. 27127). Museum: CSIRO CA250 (conspecific material). Also Ref. 5978.

Short description Μορφολογία | Μορφομετρία

Ραχιαίες άκανθες (συνολικά): 9 - 11; Μαλακές ραχιαίες ακτίνες (συνολικά): 22-24; Εδρικές άκανθες 4; Μαλακές εδρικές ακτίνες: 20 - 23. Gill rakers rudimentary. Minute scales present. Highly compressed body (Ref. 4253). Large dark spot, surrounded by a light ring on each side of the body (Ref. 35388).

Found in areas close to the sea bed (Ref. 6390). Generally solitary. Feeds mainly on schooling bony fishes, occasionally on cephalopods and crustaceans (Ref. 27121). Reproduction takes place at the end of winter and at the start of spring in the northeastern Atlantic, earlier in the Mediterranean. Eggs are pelagic, maturity reached at 4 years (Ref. 36731). Sold fresh (Ref. 9563) and frozen (Ref. 9988). Can be steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). The flesh is excellent but is utilized little in West Africa (Ref. 5377).
