The invasion of Macrobrachium nipponense (De Haan, 1849) (Caridea: Palaemonidae) into the Southern Iraqi Marshes , a 2006 article, may be accessed here as a PDF document. The introduction vector for this East Asian species (also accidentally introduced to the Caspian Sea, along with power plants in...

They're actually Euryrhynchus of some sort, possibly E. amazoniensis.

He was referring to Syncaris pacifica , native to "lowland perennial streams in Sonoma, Marin and Napa counties." Habitat loss has rendered this Atyid (with the 1930s extinction of Syncaris pasadenae of southern CA, the sole surviving member of its genus) federally endangered. Further info...

Thanks for the information.

Attempts have been made to hybridize M. carcinus with M. rosenbergii for increased docility, of all things.

Perhaps we will have to arrange a forum collection trip to someplace :-D Shoulda seen the look on my parents' faces when I said I wanted to go to Sri Lanka :lol: -John Puerto Rico, as a commonwealth of the United States, may be the most feasible option (in terms of legal practicality and proximity)...

Have any of us reared M. carcinus? Several DNR-associated researchers in Puerto Rico have reported to me their inability to keep adults alive in captivity for prolonged periods (allegedly on account of their "restlessness" in small setups). Mustafa -- I'd especially like to see some images...

Slightly OT, but has anyone seen suppliers listing any of those odd, dorsoventrally flattened crayfish (I think that's what they are) from South America? I've seen photos here and there, but I was wondering if they've been appearing on importers' lists. Those are probably Aegla spp., which are neit...

My thinking was shrimp also. Due to rounded fuzzy claw and legs. I will get more info monday. The mountain info made me think strictly fresh also. To second Mustafa: The tenacity of these shrimp is legendary. One story tells of a flabbergasted air-conditioner serviceman who found some tiny mountain...

I purchased a very similar female specimen under the heading of "chameleon prawn."

Will it eat fish as well? I would never have thought a FW shrimp would grow so large, and be so aggressive. To put it simply, M. rosenbergii will eat fish (though small, swift-moving species are sometimes ignored). Some aquarists have claimed success with adult prawns and certain comparably-sized p...

Also, at what ph do you keep your shrimp? The literature says that they occur in acidic waters, but that does not necessarily have to be true for all populations. Around 7.3 or so. On another note, I've seen some mention of the sergestid shrimp Acetes paraguayensis . To your knowledge, has this spe...

Euryrhynchus , True blackwater species. However, it's like a roach. It's *TOTALLY* nocturnal. In other words, you'll be happy if you *ever* see this shrimp once you put it in your tank. They sit in some dark corner all day long. Not suitable at all for the hobby in my opinion. I have a few of them ...

I would not be surprised if species such as Xiphocaris, Jonga and various Macrobrachium sp. not reported from Florida do end up being discovered in Florida in the future. Interestingly, I've found a paper noting presence of M. heterochirus in Florida as well. This document makes the following state...

I know for a fact that several species of Psuedopalaemon, Macrobrachium, Euryrhynchus, and Palaemonetes are native to certain blackwater tributaries of the Amazon.

So far as I know, the only species of freshwater shrimp occurring in Washington state are non-native Exopalaemon modestus (the "Siberian freshwater prawn," native to southeastern China, Korea, Japan, and segments of the Russian Far East) and Palaemon macrodactylus (the "Oriental river...
