Hi all, was wondering in anyone's ever heard of C. temasek and if so, any info on breeding them? They're a native of Singapore(where I'm from) and possibly endemic to the island... not too sure on that.
Secondly, I have 2 woodshrimp females. I'll get a male tomorrow but, any idea how to breed them? The site says they need brackish water but I have seen them occuring in dammed up rivers which have been fresh for the last 20 years... Like the 2 I caught... Ideas? Theorys? kick me in the head for poaching?
The river goes to the sea so the fry can get out. The adults are pretty determined. If there is a spillway I'll bet they can make it up. The water right under the spillway will be mostly fresh, so they will have lots of time to try.
Of course they could be the result of boored shrimp owners dumping them in the river
Why would anyone want to dump $4 shrimp I wonder... But I guess it's possible the little guys swam back upstream. Though the streams they use are only flowing during the monsoon season.
And caridina temasek? Anyone have any info on those little guys? And yes, I realise the irony of a singaporean native asking americans/europeans/australians about another singaporean native. But hey, we're just that screwed up
Why would someone dump a $4 shrimp? Heck, in New York we have alligators in the sewers, in Pittsburgh we have piranhas in the Monongahela. People dump $500 dogs on country roads they don't want any more.
You guys don't have a corner on the idiocy market.

Here is a very sick looking shrimp (probably died after the photo shoot) that seems to have been identified as Caridina temasek:
The care of it should be the same as for any other dwarf shrimp species, such as the red cherry shrimp. I would try to duplicate the water conditions of their native habitats, although the shrimp could be quite adaptable to different conditions. You can usually tell if you can breed the shrimp in freshwater or not by just looking at the egg size and the number of eggs. If the shrimp carries hundreds or thousands of tiny eggs, then the larvae usually need saltwater to survive and grow. If you only see 30-80, pretty large eggs, then most likely you will see some fully developed mini-shrimp hatching soon.
Do you happen to have any pictures of your C. temasek? I would love to see one of these shrimp that is not about to die (as in the picture above).
I'm actually going "Poaching" sometime in the next few weeks to try and collect a few. Looking to get about 100 of them for breeding. Our brilliant government has a habbit of "Modernising" and building restaraunts(which fold up after a few months) right on top of our more endangered species. For eg. Macrobrachium rosenbergii used to be common around here in the 1980s. In fact there was a river right behind my house. Then they built a condominium on it. And they were extinct in the wild now. Ok, going OT here.
Will post pictures when I've collected a few. M. malayanum as well. And whatever else I can find. Thanks for the pic Mustafa, at least I'll know what to look out for.
[Edit]
Isn't the presence of a larval stage one of the ways to distinguish between a prawn and shrimp? Or is just it more common in prawns than shrimp?

Unfortunately, shrimp are not high on the list of governments or environmentalists when it comes to protecting them from extinction. Many of the shrimp that perish in the animals trade by the hundreds of thousands should be protected, but aren't. That's why I am trying to establish breeding populations of as many shrimp species as possible and encourage other people to do the same.

Just keep in mind that the shrimp you will see won't look like the one in the picture since the one in the picture is a sick shrimp and has this milky white coloration which the healthy wild shrimp won't have. Also, when you catch them they will lose their coloration and you will only see their real colors when you put them in your tank and give them time to color up. Do the Macrobrachium malayanum have large eggs?
M. Malayanum have eggs approximately 1mm in diameter. I've seen a 3inch female carrying something like 40 eggs. So they can probably be bred in the tank.
The interesting thing about these guys is that they can be either left or right handed/pincered. Whichever pincer they use more often grows larger than the other and becomes "furry". This is seems to be more pronounced on the males than females.
The female in the photo is 3.5cm and the male is 5cm. 1inch = 2.5cm
I've seen bigger 4inch specimens in the wild though... Pretty big as shrimp go. Credits to hwchoy of http://www.aquaticquotient.com for the pics.
