Marron are one of the largest commercially farmed freshwater crayfish in the world and are native to the South West and Great Southern regions of Western Australia.  They can still be found in most of our rivers and creeks, especially those that have not been affected by salt and agricultural runoff.  Once they were numerous, but their numbers have been dwindling due to over-fishing, habitat decline and more recently climate change.  Whether farmed or in their natural environment they are very sensitive to the quality of the water in their ecosystem. When conditions are not right they will simply get up and walk out. Aqua-farming is a highly skilled operation with much effort and thought going into the process to ensure that the marron grow in as clean an environment and as close as possible to their natural habitat as possible. Here at Great Southern Marron we take great pride and care to ensure that we can maintain our production rates while respecting the marron stock and its impact on the environment.
