North America – Backwater of the Freshwater Invertebrate Hobby

I have been seeking “robust” freshwater prawns (Macrobrachium spp. [or, alternatively, (freshwater) Palaemon – as distinct from Palaemonetes – spp.]) for employment as the crux of both prolonged qualitative observation and experimentation (centered about review and expansion of my premise for well over a year – to absolutely no avail.

No LFS, save Petco, has ever carried Macrobrachium spp., or is willing to order them. The several times I sought to expedite a special order of “blue prawns” from this sole exception were met with blue crayfish or the claim that “the Florida facility” was experiencing unspecified – and apparently chronic – “difficulties” (the initial receipt can probably be attributed to a misshipment by suppliers).

I have exhaustively explored (and, in many cases, initiated personal correspondence with) all of the following online stores/auction hubs, none of which satisfied my requirements: Ebay, Aquabid, Bid4Pets, The Crayfish Shop, Arizona Aquatic Gardens, Fish2U, ****************, Aquarium Stuffers, Carolina Biological Supply Company, Sachs Systems Aquaculture, aquatic-store.com, Frank’s Aquarium, and Petshrimp.com’s “Shrimp Store”; Profi-Aquarium and Aquaculture of Texas remain, for my purposes, unfeasible options.

I have, in addition, posted a series of “wanted” ads across some dozen aquarist forums, all of which culminated in essentially no replies. I seized every opportunity to obtain unwanted shrimp (typically contaminants amongst feeder ghost shrimp), all of which ended in last-minute breakdown; a promising domestic importer with German contacts likewise refused to reply to my inquiries.

Seeing how my wanted ad in this forum has garnered nary a reply, I’d like to know whether anyone here has any “leads” as to potential sources.

I would prefer the more robust-clawed (crayfish-like as opposed to “ghost shrimp-like” forms) – sub-adult M. rosenbergii, M. lar, M. nipponense and the like are, however, more than acceptable.

I am seeking the following species in particular:

M. sp. “Indien”

”M. aus Kamerun”

M. sp. “Panama”

M. sp “Riesengarnele”

“M. sp. aus Thailand”


M. americanum

M. carcinus

M. heterochirus

M. ohione

M. vollenhovenii


M. acanthurus

M. aspericus

M. rude

M. lanciforns

M. malcomsonii

M. tenellum
 
Veneer I would love to help you but I cant because I dont live in the states.
But please dont give up , keep looking and I hope you find what you want. ;)
I have been through the same sort of situation as you but with a fish.
 
Have you contacted a Game and Fish or Department of Natural Resources in a state where they are native? Or a university there? This will likely be more successful than hobbyists, who seldom have native species. I know that here, those would be the best bets for finding out where to purchase or collect any--along with being able to detail any legal permitting requirements for them.

Thanks, but only a few species are native to North America (the introduced ranges of M. rosenbergii and M. lar respectively encompass Florida and Hawaii):

The genus Macrobrachium, or river shrimps, is represented in the United States by 6 species: M. acanthurus, M. carcinus, M. faustinum, M. heterochirus, M. ohione, and M. olfersii. River shrimps are the largest fresh-water crustaceans in North America, and specimens of the largest species, M. carcinus, can be the size of lobsters. Most of these species are distributed among the southern states of the Gulf Coastal Plain, Mexico, and the Caribbean Islands. Macrobrachium ohione is known also from the Red River drainage in Arkansas and Oklahoma, and the Mississippi River-Ohio River drainage in Illinois, Indiana, and Ohio. Because of their complex amphidromous life cycle, populations of Macrobrachium are vulnerable to anthropogenic disturbances such as construction of impoundments, water pollution, commercial fishing, and introductions of exotic species. Preliminary data from Mississippi and Texas support the notion that populations of river shrimps are restricted by impoundments, and populations, in general, are in decline. A review of the species and a revised key are presented.[/url]

I'll be sending inquiries to the Fish and Wildlife departments of Florida and Texas.
