The Australian species of the
Ariidae family have been revised andplaced in a new
genus, Neoarius. "Neo" meaning
new in Latin. Description: Anal soft
rays: 16 – 19; Vertebrae: 55 – 57. Eye
size 12.9-21.8% HL. Because of its similarity to A.
paucus, the remaining diagnosis refers to both
A. midgleyi and A. paucus: a sleek
body; strong jaws; jaws upturned slightly at symphyses,
mouth broad; snout truncate in profile; head oblong,
its width averaging 66% HL. Supraoccipital process
narrow with parallel margins. Numerous fine, sharp
teeth on palate in transverse band of four oblong
groups. No rakers on posterior aspect of gill arches.
Barbels thin and short, rarely reaching beyond pectoral
fin base and less than 25% SL . Inhabits in lakes,
billabongs, rivers and to a lesser extent brackish
estuaries and the tidal portion of rivers. Habitat:
Found in clear or turbid fresh water reservoirs and
waterholes. Reproduction: Breeds
early in the wet season, sometimes extending
into the late wet (November to March). Eggs are incubated
orally by the male for 5-6 weeks; brooding males form
groups in deeper water. Juveniles grow quickly, attaining
20-30 centimeters by the end of the first year, and
sexual maturity is reached after 3 years. An excellent
eating fish, rapidly growing in popularity. This one
is not as common as some of the other salmon tailed
catfishes but does grow very large. There are plenty
in Lake Argyle WA and the WA Gov changed the name
to Silver Cobbler to sell the flesh in the Perth Fish
Markets. Diet: Feeds mainly on fishes,
prawns and crayfish. Various arthropods are also consumed.
N. midgleyorum in Eschmeyer's Catalog
of Fishes is stated as valid but in other sources
N. midgleyi is still the name.
Northern Australia. Victoria River, Northern Territory.
