Oceania: throughout most of the Murray-Darling River system of South Australia, Victoria, New South Wales, and Queensland, except for the upper reaches of the southern tributaries (Ref. 6390). Introduced into many lakes and dams throughout Victoria and New South Wales. Their abundance has been drastically reduced across their natural range and they are now considered rare in many Victorian tributaries (Ref. 27498).
大洋洲: 在大部分的澳洲南部，維多利亞，新南威爾斯與昆士蘭省的 Murray-Darling 河流域各處, 除了支流南部的上游.(參考文獻 6390) 在維多利亞與新南威爾斯各處引入許多湖與水壩中了。 他們的豐度已經大幅被縮小的過他們的原來的分佈範圍，而且他們是現在被認為稀有的在許多維多利亞女王時代的支流中.(參考文獻 27498)

The Murray cod is one of the world's largest freshwater fish (Ref. 6390). They live in a wide range of habitats, from clear, rocky streams to slow flowing, turbid rivers and billabongs (Ref. 27498). They are generally found in waters to 5 m deep, in sheltered areas with cover from rocks, timber or overhanging banks. Adult fish are carnivorous, having a diet of invertebrates, fish, amphibians and occasionally reptiles, birds and aquatic mammals (Ref. 27498). The young feed on zooplankton. Spawning takes place from spring to early summer. Murray cod are territorial, their 'territory' associated with a specific hole, snag (large woody debris) or area of a river or lake (Ref. 27498). Juveniles may undertake migrations (Ref. 6390). Threatened due to over harvesting and habitat loss (Ref. 58490).
默里鳕鱼是世界最大的淡水鱼之一。 (参考文献 6390) 他们生活于宽范围的栖息地, 从清澈又岩石的溪流到减慢流动又浑浊的河与死水潭.(参考文献 27498) 他们是对 5 公尺深的通常发现于的水域, 在掩蔽的区域中以来自岩石, 木材或上悬的浅堆的表面。 成鱼是肉食性的, 有一个无脊椎动物，鱼的食性，两栖动物与偶然地爬虫类, 鸟与水生的哺乳动物.(参考文献 27498) 幼鱼吃浮游动物。 产卵从春天到初夏发生。 默里鳕鱼是具有领域性, 他们的 '领土' 伴随着河的特定洞，断枝 (大的植物残砾) 或区域或湖了。 (参考文献 27498) 稚鱼可能进行回游。 (参考文献 6390)

Cod form pairs & only one male spawn with each female (Ref. 27498). The spawning site can be in water as shallow as 30 cm (Ref. 27498). The male protect and probably fans the eggs during incubation (Ref. 27498).
Egg masses are laid on the bottom and adhere to the substrate (Ref. 6390).大洋洲: 在大部分的澳洲南部，維多利亞，新南威爾斯與昆士蘭省的 Murray-Darling 河流域各處, 除了支流南部的上游.(參考文獻 6390) 在維多利亞與新南威爾斯各處引入許多湖與水壩中了。 他們的豐度已經大幅被縮小的過他們的原來的分佈範圍，而且他們是現在被認為稀有的在許多維多利亞女王時代的支流中.(參考文獻 27498)
