Yabbies are pretty cool, but if one is going to discuss more serious crayfishy things then Marron are what you're talking about.
At one stage, mainly for want of better studies being carried out, there was only thought to be a single species of Marron, but it's commonly accepted these days that there are at least two. Personally, I think there may be even more, because I swear I've seen the buggers in Queensland, way outside their defined range, but of course that's just a bit of an anecdote, so we won't be discussing that any further. Probably
The two recognised brands are Cherax
tenuimanus, known as the hairy, or Margaret River Marron and Cherax
cainii, AKA the smooth Marron.
Both are native to the southwestern corner of Western Australia and are farmed there quite extensively. Many South Australians will also attest to them being about the place and in fact Marron have been introduced to Kangaroo Island and other parts of South Australia where they have been both commercially farmed and are known to have established feral populations in local waterways. A mixed blessing, one might say. I mean, they're food, after all, and quite a luxury item at that, going by the prices one pays.
It appears that
tenuimanus, which is critically endangered, may be being supplanted in most areas by the introduced and more adaptable
cainii, and it is most likely that specimens reported in areas outside the southwest are of the latter species.
Dog knows what the things I've seen in SE Queensland are, but they were definitely too big to be normal yabbies (Cherax destructor).
Normally they're as black as, but according to fairly credible reports from wandering Pharaohs, and as the following photo bears out, they can appear in a range of colour schemes incuding fire engine red (not including the ones that are about to be lunch, but that's a whole different thing).
Both species grow to about 2 kg (4½ lb) if they don't get eated first.
As always, don't try this at home, kiddies - they're every bit as bity as they look
Scientifical Stuff:
Kingdom: Animalia
Phylum: Arthropoda
Subphylum: Crustacea
Class: Malacostraca
Order: Decapoda
Suborder: Pleocyemata
Infraorder: Astacidea
Family: Parastacidae
Genus: Cherax
Species: C. tenuimanus ('hairy') C. cainii ('smooth')
Non-Scientifical Stuff:
Marron make excellent eating, very similar in taste to lobster. Being that they are a freshwater species, however, they are far less salty and provide an overall sweeter taste. Distinct from all other similar freshwater species is the fact that they do not burrow and do not take on as much waste into their flesh.
"Recipes?", I hear you asking. Well, duh.
Char grilled marron with orange and ginger sauce
4 large marron
1 cup orange juice
1 x 2cm piece of ginger peeled and finely chopped
Sea salt to taste
1 cup butter diced
Pop the marron in the freezer for 30 minutes. This will improve their temper somewhat. Remove and cut in halves.
Rinse to remove comic cuts.
To make the sauce, simmer the orange juice and ginger and reduce to about 1/3, swirl in the butter a few pieces at a time, keeping the sauce warm but do not boil.
Season the marron. (salt, pepper, other stuff)
Lightly brush with the melted butter and char grill 3-4 minutes on each side.
Arrange the grilled marron on a plate surrounded by the sauce and serve immediately.
Alternate Serving Suggestion - Cooper's Special Sauce (goes well with anything)
