    Re: Marble Crayfish- Marmorkrebs

    Hi jackolope, not to hijack the thread, but what kind of snails do you use? I have tilapia as well, and it's always great to add more cleaning and sources of protein.

    Re: Marble Crayfish- Marmorkrebs

    Keith, I don't suppose you would be willing to part with a few of them, would you?

    If so, let me know what you would want for some. I wonder if these live through being shipped?

    Thanks,
    -Larry

    and if any breed in the pool (i put several berried krebs in the pool so far) they will end up feeding the yp and bluegill

    i don't have the boxing and insulation to ship... but, you can find them on aqaubid.com..
    i started with 1 - i got it free with an order of gammarus (scuds) a couple years ago - you can get a better deal on the scuds from JCO...
    if you were close i'd gladly give you a few

    I understand. We are 400+ miles apart, so a bit difficult to just run over

    Re: Marble Crayfish- Marmorkrebs

    Very informative information about Marble Crayfish- Marmorkrebs for aquaponics systems. The interesting point for me is that they are all females and they lay fertile eggs.

    What happen to males over the years??

    Re: Marble Crayfish- Marmorkrebs

    No one knows I guess... but here is a quote from Badflash with a possible answer

    These are an interesting breed, sort of a frankenfish. No one knows where they came from, but the conventional wisdom is that they came from an accidental hybridization between two different species of north American crayfish.

    Marmorkrebs are the only known species of crayfish that are all female. Each female is identical to the mother and she produces fertile eggs without mating.
