no.
Where are people getting their information for this. The Murray cod doesn’t live anywhere else beside the Murray river . Really? Lol.
Murray cod was created in 1838.
A Murray Cod is a type of fish, common to Australia.
The Murray cod is a fish that only lives in the Murray-Darling River system. Although they are called cod, they aren't related to the northern hemisphere cod. The Murray cod's conservation status is Vulnerable. They are threatened because of previous overfishing, as well as dams, and introduced carp and illnesses.
Yes
Koi are simply a species of carp and they are not regarded as "predatory" although they will eat fish that are much smaller than them. They are omnivores and they grow to around 24 inches or so. Murray cod on the other hand are a very large predatory fish They only eat other living creatures including fish, crayfish, water birds (ducks) etc . They grow to over 5 feet long. Murray cod will eat Koi carp if there is a sufficient size difference.
Murray cod are important as a large, beautiful and highly distinct Australian native animal. They are an icon of the Murray-Darling river system in which they occur, and are symbol of the river and its health (or lack of health). They are of great importance to both European and aboriginal people of the Murray-Darling river system. Murray cod are approximately the 4th largest wholly freshwater fish, which is a remarkable achievement in Australia, the driest inhabitat continent in the world.
Vertebrate :)

Cod. Or as the Danes call it; "New Years Cod"
If you kill a Murray cod, you can tell if they are male or female by cutting them open and by looking at their gonads, which are their reproductive organs. However, this is a very bad idea considering how rare Murray cod are. If you are not prepared to kill a Murray cod, you will not be able to tell if it is male or female, either by size or appearance, for most of the year. (Male and female Murray cod look the same and grow to basically the same size.) However, for several months in late winter/early spring female Murray cod can be recognised because their belly region will be noticeably swollen with the large eggs they are carrying and their vent will be swollen and purple or red.
Murray cod are actually very tolerant of rising salinity levels. As a matter of fact, aquariums which keep Murray cod add small amounts of ordinary sea salt to the water because it imrpoves the health of the fish and minimises bacteria in the water.
