buying marbled crayfish

[MN_Rebel]

Think before you buy. Soon you will be overwhelmed with crayfish and wont know what to do with them. If you are planning them as feeders thats fine. But this cray is dangerous because of the way it spawns. Im sure they will eventually be banned when more people start getting their hands on them and are careless. Some will make it to the wild and there will be problems.

So again, think before you buy. This cray can get out of hand if you have no plans to dispose of all the babies properly.

Also this marbled crayfish have no natural range as this species do not existed in the wild. I dont trust that guy whos claimed that its okay to use marbled crayfish as bait and cannot survived in United States waters...total bs as this marbled crayfish can hybridizing with other crayfish species. I agreed with Pyramid_Party, this species will eventually become banned and we cannot let it happened as this species are very useful as feeders and are very interesting crayfish as long as no moron dump them into the waterways.

The idea behind the bait thing being okay is that the Marmorkreb is so non-aggressive that even with the ability to produce large amounts of offspring, it still gets decimated by naturally occurring species. Though, valid reports go both ways on this subject, at this point even in states and countries where they've been made illegal, the reports are still "inconclusive" as to the actual impact on the environment. (Not to say it's not a valid issue)

And the Marmorkreb is in fact used as a bait crayfish, though certainly a lot of other species are still more wildly used currently (and subsequently spread, as well). These are becoming more popular because they are easier to handle and don't often, if at all, pinch when being handled. By the bye, that website suggests freezing the crayfish before using them as bait to avoid ecological issues, so they're not advocating using them live or allowing the spread of them.

Additionally, this species does not hybridize with other species. Not that's been reported at least, though if you can find me a report of it I'd certainly love it for my own research gathering. You could probably get some interesting hybrids if they did. But that's beside the point...

This species does require more consideration before being obtained because of it's ability to reproduce by apomixis, at such frequent intervals and so easily when given ideal conditions. If you don't have the means to PROPERLY re-home, sell or dispose of the offspring you should look into getting another species.

I have no proof that they are very popular bait crayfish, however they are popular feeder. I personally dont believe that marbled crayfish cannot survive in the United States because of temp, but isnt that marbled crayfish are closely related to the Red swamp crayfish or possible hybrid of this species?

I want some, somone send me some babies. 12 for 100$ yeah right.

Why need 12? Why not just a single crayfish or two then in few months you will have lots of babies crawling over your place.

There isn't proof needed for that, just stop in a half dozen bait stores... you'll see them in at least a few of them (at least around here). And they definitely are a popular feeder, the only people who buy my offspring are people or stores who want feeders.

I couldn't find any reference to them not being able to survive in the US in that site. But they definitely can, many people have introduced them to their outdoor ponds throughout the US to be used as food for whatever they're keeping. But they can definitely survive here. They can weather German winters easily, so they can surely winter ours. And the they can handle Madagascar's summer heat, so they can also handle ours.

Marmorkrebs are a proposed relation to NA Procambarus species, but with no direct link to any one species or that genus being found yet. This in part being due to the fact that it is still largely debated whether this is a new species or a hybrid.

One problem: Marmorkrebs are discovered in some pet store in Europe and it appeared that marmorkrebs have no natural home range or any native range....we still have no idea where this species really come from, so this species sure have mystery history...just like flowerhorn and blood parrot cichlids.

Really? The seller/owner of that Marmorkreb website said they cannot survived in United States water.

I looked through it, I didn't find that reference. What page was it on? They'd need to be notified about that, as it's blatantly untrue. Well, untrue related to water temperatures and conditions. The owner/seller may be one of the many people that subscribe to the idea that if introduced to the wild, the natural species would decimate them, thus avoiding any ecological issues. (not necessarily a wise view, imo, but not unfounded either)

This owner said that in other thread in here, claimed that they cannot survived in United States winters.

For one thing, I would be very surprised if this species is on ANY state list. And, all evidence seems to indicate this species could not live through the winter in any state, not even Texas - much less Wisconsin. By all means, investigate your own state lists for prohibiting species of any kind, I am all for it. But there is no need to add paranoia to a species already villified by British press - there is a lot of good that this animal could provide to the world, in the bigger picture.

Still we dont know if it could cause problems in the waterways or not as its not happening right now as this marorkerbs' still new to the American aquarium hobby, but it take just one marmorkerb got stray in the waterways then you will find some of feral marmorkerbs soon. (reason i say feral because there are just no wild marmorkerbs existed)
