Where are people getting their information for this. The Murray cod doesn’t live anywhere else beside the Murray river . Really? Lol.
No, they are brothers. Bryan is Bill's older brother

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.
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.
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.
The largest Murray Cod on record was over 1.8 meters, and cod are regularly caught over the 1 meter mark. Larger Murray Cod are found in South Australia more so than in the Murray along the NSW/Victorian border, but this is not to say regular catches in the vicinity of 1.5 meters are not made along the entire length as well as in other river systems in the surrounding areas.

Murray cod (Maccullochella peelii peelii) only occur naturally in the Murray-Darling river system. They were originally present in almost all parts of the Murray-Darling system. They once occurred in surprisingly small streams before they were silted and degraded by bad farming practices, and contrary to popular belief, originally occured in cool, quickly flowing upland rivers to quite high altitudes. Murray cod still occur in some high altitude upland rivers in northern NSW. Murray cod have been introduced to some river systems outside of their natural range. Murray cod also manage to cross the Great Dividing Range into the Clarence River system between 1 and 2 million years ago in a natural river capture event, where a Clarence tributary cut into and captured the upper reaches of a Murray-Darling tributary. However, the cod that got into the Clarence River system have evolved into a separate species of cod called Eastern Freshwater Cod (Maccullochella ikei) or Eastern Cod for short. Through this mechanism cod also colonised the Richmond, Brisbane and Mary River systems, also likely to have been between 1 and 2 million years ago. Richmond and Brisbane River cod are now extinct. Mary River cod survive today but are endangered, as are Eastern cod. Murray cod are also considered threatened.
Murray cod can live in surprisingly different habitats. Contrary to popular belief, Murray cod can live in quite cool, clear, rocky fast-flowing streams at medium, high and sometimes even very high altitudes. These are what are called "upland" rivers. Many populations of Murray cod in upland streams have died out, but some still exist. Murray cod also survive in warm, slow rivers on the riverine plains. These are what we call "lowland" rivers. Murray cod also survive well in lakes and reservoirs of all kinds, though they do not seem to breed successfully in them. In rivers Murray cod require a little bit of depth, and shelter in the form of rocks and rock structures in upland rivers, or sunken timber in lowland rivers. Murray cod will generally not survive in rivers that have been severely silted up with sand or silt as there is no depth or structure for them. Riparian (river bank) vegetation is quite important too. Removing snags has left many rivers without Murray cod habitat. While Murray cod can survive naturally cool streams, they cannnot survive thermal pollution, where big reservoirs release freezing water from their base and make rivers unnaturally cold for several hundred kilometres downstreams.
