Do unmated shimp get berried?

[nacra99]

My lone sulawesi shrimp seems to be holding some eggs...
I thought that shrimp only get berried when they have successfully mated... or is that wrong?
She's the only sulawesi in there with a bunch of Cherries....  could she have mated with the cherries?

hmm... coming up to a week and a half and it's still holding!
It would be a crazee awesome discovery if it actually crossed with the red cherries

Re: Do unmated shimp get berried?

how long has she been in there?  I know some crustaceans can store the sperm until later... maybe she's done that?

Re: Do unmated shimp get berried?

I bought her about 3 weeks before i noticed the berries.
Do you think she could store sperm for that long?

I really have no idea... I only have RCS and blue crays... I know the blue Crays can store it for a good while...


check this out... its from a cache of a planetinverts page... ... http://209.85.173.132/search?q=cache...ient=firefox-a

I don’t think that the eggs are fertilized!
MYTH. If your female is carrying eggs then they are fertilized. The eggs become fertilized as they move down into the “carriage”. The male deposits the sperm into the female before the eggs are in the carriage. As the eggs are moved from the ovaries and into the “carriage” they become fertilized by the deposited sperm. If you think that your female shrimp has carried her eggs for too long it is because the babies are not fully developed and are still growing. Be patient, it can take some time before the eggs hatch.

also check this link out, it discusses the mating process for shrimp... bummer none of the pics got cached...

I know that planetinverts turned out to be a pretty bad place to get shrimp... but maybe the info is good?  I didnt see many other promising links when searching around.

They can be berried and not fertilized... she will carry them for the term and just drop them.


I have had Lysmata amboinensis pack all the time and it was by iteself. Recently picked up a few more and now she's berried again!

Re: Do unmated shimp get berried?

aww... boo... they'll drop them? I was getting excited there for a while.
Looks like i have to go hunt down a male... kinda hard coz nobody seems to recognize this one shrimp.

planetinverts.... grrr...............

Yep if your sure that it is the only female in the tank then yes these a duds.  But it not always a bad thing.  Since she has done this if she ever mates with a shrimp the babies success rate increases most likely.
 Often Premature Crayfish do this to except usually if there eggs are infertile they will start eating them one by one.

Re: Do unmated shimp get berried?

From my experience all berried freshwater shrimp females have fertilized eggs. However, the rules could be different for sulawesi shrimp. It is also possible that it did indeed store the sperm for that long.

As for the Lysmata amboinensis, that is a saltwater shrimp so I do not know the rules with saltwater.

Do you have other photos of that shrimp?
