    Default Marmorkrebs/Marbled Crawfish as Bait

    Does anyone know of any laws in Louisiana related to raising crawfish for bait, specifically the marbled crawfish? I just saw a Craigslist ad which was advertising the Marbled crawfish and their selling point was that they are easy to raise for fish bait. I didn't know what a marbled crawfish was so I googled it and it seems it is a type of crawfish that was discovered some years ago in a German pet shop and scientists don't know exactly where it came from but they have the ability to clone themselves. All the marbled crawfish are female and they secrete some type of stuff that allows them basically self produce without any males. Each one can produce 400 babies every 3 months and each one is an exact female clone of the mother.

    It only takes one of them to start a whole colony and they reproduce fast, can withstand cold winters, and can live without water long enough to travel over land to other ponds and lakes.

    The problem is that they are considered an invasive species in some states like Missouri which has banned them but many states are seeming to ignore the threat. I do not know if Louisiana has any laws preventing the sale or importation of them but maybe one of you knows?

    On one hand I think they are pretty neat but on the other I don't know if raising them for fishbait is a good idea. They say that if you have a 100 gallon aquarium you can start a colony and within 6 months have thousands of them. They reproduce so fast that people who raise them to sell them can't get rid of them fast enough and end up dumping them in local rivers and lakes which is why some states have banned them even as pets.

    It sure will be interesting to see what kind of informed response you get on this. Maybe a local crawfish farmer will respond with factual information.

    I've never heard of those, but find it very interesting. First thought was, I wonder if they taste as good as the regular ones! lol... So I looked them up and found the same info you mentioned above. This link does call them invasive and that "Marmorkrebs should not be kept in outdoor tanks or ponds, used for bait, or used in any other situation where they could be released into natural ecosystems".
    Marmorkrebs.org: Advancing research on marbled crayfish



    Near the bottom is a link to this page on laws, that states as of 2011, only Missouri specifically prohibits that specific type of crawfish, but several states have laws that prohibit introducing non-native species into the water. Sort a generic "don't dump strange animals here"... In Wisconsin you can't even have live crawfish and fishing equipment in the boat together.

    North American laws concerning crayfish



    Interesting topic, thanks for posting about it.

    With that info this doesn't sound like a good thing to have around. We have a bunch of non-natives here in Florida that have caused problems.
    We sure don't need any more. Edited: I just read your link. Seems we already have them in Florida, but have never heard of them before.
