Murray Cod is Australia’s largest freshwater fish and probably the most iconic, occurring in freshwaters of the Murray Darling river drainage. It can move hundreds of kilometres but is mostly sedentary and territorial. Once it formed the basis of an important commercial inland fishery which has now ceased, and it remains one of the most popular recreational species. Their eating qualities are excellent and are in high demand.  It is a prized angling species and aquaculture species that can grow to a length of 1.8m and weight of 113kg, and living nearly 50 years.  Murray cod have a closed season for anglers between 1st September - 1st December and there are strict size and bag limits. Murray cod are not suitable for small farm dams but are known to live and breed in large impoundments in the Murray Darling system.
