marron farming

Marron are the largest farmed freshwater crayfish in the world. Only two species native to Tasmania grow to a larger size however these are not produced commercially.

Marron are grown in ponds and dams designed to optimise their growth and to allow for ease of management and harvesting.

Marron breed only once per year during early spring when day length and water temperature start to increase. Females incubate their brood of up to 500 eggs for 3-4 months before releasing the hatchlings into the water around the start of December.

In commercial ponds marron are given everything they need to grow including daily feeding, aeration, purpose built habitats and protection from predators.

At 18 months of age, each pond is harvested by draining the water away and picking the marron up from the hard base of the pond. After pick up, all marron are washed vigorously in a purging tank to clean them up. By now the marron will have an average size of 70-150g. The marron will then be sorted and restocked for further grow-out.

At 30 months or 2 ½ years the ponds are drained again. With an average size of 150-250g, the marron are then either sold to market or maybe selected for future breeders.
