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.
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.
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.
no.
it prefers death over survival its one of those rare suicidal breeds
Vertebrate :)
yes there is i live in cowra where the lachlan river goes through i have caught yellas redfin trout cod Murray cod and carp from dude who goes fishing aheap
The sex of Murray cod is determined by examining their reproductive organs. In males, testes are present while in females, ovaries are found. The examination is usually conducted by a trained professional such as a fisheries biologist.
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.

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.
