Comments: Bluespot trout inhabit only Queensland waters, from Torres Strait to Gladstone (Ref. 6390); Northwest Shelf (Ref. 90102). Commercial fishery: Bluespot trout are fished on the Great Barrier Reef by handline. Coral trout, in general, are the major Queensland commercial finfish, worth about A$8.2 million in 1989-90. They are one of the target species groups of the Queensland East Coast Reef Line Fishery and comprise 31-34% of the catch from that Fishery (Ref. 27262, 27263). The fishing fleet operates predominantly from ports between Cardwell and Mackay (Ref. 27263) and is very mobile. It concentrates in regions such as the Swain Reefs, the Whitsunday Island Group and the far northern Great Barrier Reef on a rotational basis. The Reef Line Fishery is daytime based and conducted by individuals operating small dories or dinghies ('tender vessels') working to a mother ship. Generally, coral trout are caught in commercial quantities from Torres Strait to just south of Rockhampton (Ref. 27262). Catches peak in the waters off Mackay and only small catches are made south of Gladstone. Although coral trout are caught throughout the year, catches and fishing effort are higher from August to October (Ref. 26263). In north Queensland, coral trout are caught by shallow and deepwater handlining off the reef crests. They may also be caught using rod-and-reel and by trolling ('wogging'). Cut baits from oily fish such as tunas and mackerel (Scombridae), frozen pilchards (Sardinops neopilchardus) from Western Australia and shark (Carcharhinus species), and also squid are commonly used (Ref. 27264). Fishers often target spawning aggregations of common coral trout and bluespot trout, and also seek 'plate-sized' trout about 35 cm FL. Coral trout are an excellent table fish marketed mostly fresh, gilled and gutted, or as fillets. Recreational fishery: In north Queensland waters, considerable quantities of coral trout are taken by handline and rod-and-reel. The fish are caught mainly during the day in depths to about 25 m (Ref. 27264). Coral trout are also caught by spearfishing to about 20 m depth. Small vessels are used on inshore reefs. Fishing in deeper water to 40 m is occasionally conducted from charter vessels (Ref. 27262). The quantity of coral trout taken in the recreational fishery in Queensland is estimated to be the same as, or more than, the quantity taken in the commercial fishery. The largest recorded coral trout caught by a recreational fisher was 23,600 g from Queensland (Australian Underwater Federation records). Resource status: In Queensland, there appears to be 'localised' over-fishing of bluespot trout on reefs near centres of population, and the average size of coral trout is smaller on reefs that are fished compared with the size of coral trout on closed reefs in the Capricorn Reefs area (Ref. 27276). Over the whole Great Barrier Reef however, coral trout densities until 1993, appear to have remained stable over a considerable time period. As of 1993, despite both recreational and commercial fisheries targeting the same species using the same gear and methods, it appeared that the resource had not been over-fished. However, fishing effort on coral trout is increasing from both fisheries. Also Ref. 2334, 4787, 33390, 37816.

A voracious piscivore inhabiting coral-rich areas of lagoon and seaward reefs. Encountered most frequently in channels and outer shelf reefs. Migrate over short distances to spawn, forming large aggregations, maybe 1 or 2 per reef (Ref. 6390). Feeds mostly on fishes, and occasionally on crustaceans (Ref. 9710). The prey comprises a variety of large reef fishes, including groupers, and this diet of large fishes is responsible for the high concentrations of ciguatera toxins. Juveniles may mimic the pufferfish Canthigaster valentini. Usually wary (Ref. 9710). The young have a demersal existence in shallow water in reef habitats, especially around coral rubble (Ref. 27259). They feed on small fish and invertebrates such as crustaceans and squid (Ref. 27261). Eggs float just below the surface (Ref. 6390). The pelagic larvae are found in habitats similar to those of the adults (Ref. 27260). An excellent table fish (Ref. 6390).
