Are self cloning crayfish legal to keep in Australia?

Recommended Posts

Hi guys,

I have read that self cloning crayfish babies are great live food for larger fish, I want to ask though is it alright to keep in Australia as it can quite easily take over an existing environment as it does not need a partner to self reproduce?

Cheers Chi.

I'm not sure what you're species you're talking about but AQIS don't allow the importation of live crustaceans into the country.

Marmorkrebs, or marbled crayfish is what they are called but what if they are in the country already but still illegal to keep like Marimo Balls? Hence my question.

If they are here, I'd be interested. Read into that what you will.

So yes they're still technically illegal having come into the country after the allowable imports list was implemented. Under the biodiversity act they can come and take them. Since they haven't been legally imported into the country.

I have seen these marbled crays on another forum, and although interesting in their cloning ability and quite pretty in markings they are accused of carrying a lethal disease that they are immune to but all other crays are not. They also out breed all other crustaceans and would then stripe an eco system bare in no time.

As tempting as they would be for a quick easy food source for some fish species, personally I would stick with shrimp or other less invasive live foods.

I would hope they are not here, but the importation of them is totally out of the question and should not be encouraged.

Why not breed one of our natives, in the right conditions they will breed very well and we have many, many wonderful species here. I think Red Claw are noxious in NSW?

Noted, thanks guys will stick with legal inverts/fish just wanted to know if they were or not. Although I was reading a report on how these cloning crays could potentially solve the world's hunger problems one day.

Provided they never got into any waterways and the inherient disease they carry never escaped they probably could solve a lot of food issues both for people and food stocks for farmed fish, but I think the risks far out weigh the benefits to having them in Australia.

Red claw are almost a pest every where but they are hardy, do well in dams and aren't bad to chew on if you like eating them.

I can't find any research saying they carry disease, all I could find is Marmorkrebs seems to be closely related to the North American crayfish Procambarus fallax, and may therefore carry a highly infectious fungus that the American strain is known to harbor (Ref. http://iz.carnegiemnh.org/crayfish/phpbb3/viewtopic.php?f=15&t=192) Which states they may carry the fungus but yet to be proven?

      Ahhh ... the age old question of how to trigger your shrimp to breed. We will have to assume you have at least 1 male. What are you feeding them? Feed frozen bloodworms twice a week. The additional protein will give them more energy. Add more Indian Almond Leaves (aka Cattapa leaves) to the tank to promote more tannins and biofilm. Try raising temps to 23C or 74F. A 10% water change might help the females moult.

      No it won't have all the minerals needed for plants. SS GH/KH+ is made up of Calcium carbonate, Magnesium.   Anubias is a slow growing plant, so it does not need much fertilisers. Mosses will grow with out any added ferts. Hairgrass and whatever you have in the back corner will survive without added ferts. Give it CO2 while your tanks is empty of shrimps.    Aim for 4-6 GH.

      Hello, again.  I really appreciate everyone's wisdom on this topic.  Since I last posted, I lost my 29 gallon tropical freshwater aquarium to a sudden leak. 😞  Thankfully, I was able to save and rehome all the fish.  But, that means my 7 gallon shrimp tank received an upgrade wrt live plants and gravel.  I was hoping that would inspire some mating behavior, but I actually witnessed a female discharging what must be unfertilized eggs just this evening.  The male shrimp (I thought I had two, but now I'm questioning the other's sex after some weeks) is not doing his job and I can't figure out why.  I had to siphon out 50% of the water to move it from it's prior location beneath the 29 gallon.  I have not performed another water change in the nearly 3 weeks since the leak happened.  I check the parameters in the 7 gallon once a week and ammonia, nitrate, and nitrite are 0ppm.  Temp remains at a steady 72 degrees.  The shrimp are as active as ever but that male is unexcited by a tank full of females.  No clue what to do next.😑

      I'm thinking of ordering that "Salty Shrimp - Shrimp Mineral GH/KH+". My only concern is, does it also have all the needed minerals for my plants? Edit - If I was to use my tap water, what kind of GH should I be aiming for?

      WOW, that's hard water all right! Amazing how different it is to mine as probably only about 25 miles between us???? You were right to use RO water so at least you have a good starting point from here in! The PH may be the biggest issue as remineralising with a shrimp specific GH/KH+ will sort everything else with RO water. Cherry shrimps are pretty tough and adaptable so will tolerate PH below 7 but the nearer you can get to 7 the better, and a long time acclimating the shrimps using a dripper (there is a tube with regulator sold by ProShrimp for about £10 I think if you don't already have something) will be needed! The soil will take longer to loose its PH buffering ability with the RO though! There are a number of ways you can go from here: 1) RO water plus a GH/KH+ and try to get the PH up somehow although you will be fighting the Soil until that exhausts its buffering ability. 2) You could mix RO and (dechlorinated) tap water at 3:1 and then use a GH+. I do a 50/50 'similar' (half tap water, half brita filtered water) on my oldest tank. can't even remember why but I believe in 'don't try and fix it if it isn't broken' so have just carried on ever since. The mixed water would start at PH 6.2, TDS 70(ish), GH just over 4, KH just under 4 and then you can mineralise it (GH+ only) for the rest. This will exhaust the soil buffering quicker than 1 above and you will save a bit on RO water, use less (about half as much) mineraliser etc. You may think this is a bit too fussy a route though, and the soil will still buffer anyway, just not for as long as all RO water, and when it stops buffering you will have a PH closer to the ideal for the shrimps. Probably where you are now I would just get the snails for now until you have stopped adjusting the water or at least decided where next, probably not much longer before you get shrimps. I would also try turning off the CO2 and just see if it is really needed, if it looks like it is you can easily turn it back on then, but shrimps will do better without it and it MAY not be needed, same for fertilisers??? At least you are doing all this before getting the shrimps, very smart as most of us have learnt the hard/wrong way................ Simon
