More Info


Distribution

Endemic to the Fitzroy River system, QLD (23 30’S), and transplanted to other rivers of east QLD as far south as the Mary River (25 40’S).

Inhabits still water billabongs or large pools and slow flowing sections of streams; usually in quite turbid conditions; often near the surface or near shore among aquatic vegetation.

Features

Dorsal fin 15-19; Anal fin 25-27; Lateral line scales 32-35.

Body elongate and laterally compressed; dorsal profile of body and head straight; body moderately deep (24% of SL), slightly more so in females; head length less than one quater SL; mouth dorsally orientated, steeply sloping and extends back to rear margin of eye. Head scaleless; thick, bony scales with canals which form a mosaic-like pattern covering body. Soft dorsal placed posteriorly; pectorals pointed, reaching pelvic bases; anal fin underneath dorsal.

Size

Maximum TL about 100cm, commonly to 55cm.

Colour

Brown to olive overall with a silvery sheen and 1 or 2 orange to pinkish spots on most scales; median fins dark grey with a blackish edge and speckled with small pink spots.

Feeding

Opportunistic carnivore feeding on aquatic and terrestrial insects, small fishes and crustaceans.

Biology

Spawning by direct pairing after a prolonged courtship, generally from September to early November when daytime surface temperatures exceed 20-23°C. Females brood clutches of 30-180 eggs in the oral cavity. Eggs large (10 mm diameter). Hatch at 10-14 days, 15-36mm TL, and remain in the mothers’ oral cavity for another 4-5 weeks. First feeding at 2-3cm TL on micro-crustaceans, become independent of the mother at 3.5-4cm TL.

Fisheries

Renowned angling fish prized for its fighting ability and eating quality. Also traded in the aquarium industry. Territorial and aggressive towards other fishes, especially conspecifics.

Remarks

The species was originally described as leichardti and undoubtedly named after the explorer Leichhardt. Berra (1898) argued that the original spelling should be emended to leichhardti and some followed that suggestion (Paxton et al. 1989; Allen et al. 2006). However, the International Code of Zoological Nomenclature states that a misspelling must be apparent from the original description. It is clear from information not included in the publication that the fish was collected by Friedrich Wilhelm Ludwig Leichhardt. However, Günther indicated that the fish was collected by Dr Leichardt and used that spelling five times in the paper and used the same spelling subsequently (Günther 1868). A search of fish literature indicates that the spelling leichardti is far more common than leichhardti and consequently the subsequent spelling of leichhardti does not qualify to become the correct spelling under Article 33.3.1 of the International Code of Zoological Nomenclature (2000).

Species Citation

Scleropages leichhardti Gunther, 1864, Ann. Mag. Nat. Hist. (3)14(21): 195-197. Type locality: stated as the Burdekin River, QLD, but thought to be the Fitzroy River as the species is not native to the Burdekin River.
