Macrobrachium rosenbergii

13. August 2018

The largest species of freshwater shrimp at all is Macrobrachium rosenbergii. Males of the species can reach a length of 50 cm (inclusive the long arms), as is shown by the specimens we photographed years ago on a food marked in Thailand. Despite that enormous size the species does not get old. Scientific research found that the shrimps live only 1.5 years. In this time they sometimes wander more than 1.000 km upstreams of rivers and back again, for the larvae can hatch in marine environment only.

Macrobrachium rosenbergii is heavily used in aquacuture in southeast Asia. We import medium sized specimens (body length without the arms 6-8 cm) on a regular basis. Some females of that size from our current stock have spawned now!

For our customers: the animals have code 484554 on our stocklist. Please note that we excvlusively supply the wholesale trade.

Macrobrachium scabriculum

18. December 2017

We have obtained once more beautiful chameleon shrimps (Macrobrachium scabriculum) from India. The common name for that species has been given by Uwe Werner due to the change of the basic coloration during the life. Initially these shrimps are translucent, then they usually become blueish, then brownish and finally almost black. Only the contrasting stripe on the back is present the whole life through. Males become about 6.5 cm long, females about 5 cm. Males develope on one of their chelipeds a kind of fur. The eggs produced by this species are very small, the larvae have to be reared in marine water. As soon as the young shrimps look like shrimps they leave the sea, enter freshwater and stay there for the rest of their lifes.

For our customers: the animals have code 484712 on our stocklist. Please note that we exclusively supply the wholesale trade.
