Who loves Marron? These popular creatures are much sought after by diners, but how much do you know about them?
Marron are the largest freshwater crayfish in Western Australia – and the third largest in the world.
They are endemic to south-west WA and fishing for them has long been a WA tradition.
Due to overfishing, the majority of marron today is farmed.
There are two ways to farm marron – semi-intensive and extensive.
Semi-intensive is where you control the depth of water, their food, oxygen levels and provide predator protection (netting over the ponds). Under this method, the marron will grow 100grams per year.
In extensive, there are few inputs and the marron exist in farm damns under logs. Under this method, when their feeding is not controlled, they grow 50grams per year.
They can take two – three years to reach a marketable size.
An entrée size marron is about 100 – 250 grams.
A full-size marron can take up to twenty years to grow and can weigh between 800g – 1.5kgs.
