I never did it myself but I did run across these a few months ago when looking into giant freshwater prawns.

Hi Coopa we have discussed the Idea here viewtopic.php?f=25&t=5561&st=0&sk=t&sd=a&start=15 the main variety we were talking about was Machrobrachium australiense a murray river prawn, you can get them on the net at inflated prices, AquaBlue seafoods will also be doing them, if you are aware of a freshwater prawn (edible) in West Oz I am very keen to try them, I have glass shrimp in my system and they go well

Has anyone tried to eat a fresh water prawn? How do they match up to SW shrimp?

I don't think you'll find there's one that you can grow without a fair bit of heating Coopa. Macrobrachium rosenbergii is another commonly cultured one.

Nocky are you using them for a food source for your main fish?

I am also very interested in freshwater prawns to clean the roots in my DWC GB.

There is only drawback to sustainable culture. (I am 80% sure of this) Most if not all freshwater prawns require saltwater to breed and live through their larval stages. Its a relic of their evolution from saltwater prawns.

The idea of sustainable food is interesting as I see it current use of aquaculture pellets is not sustainable and is the only weakness I see in AP as a concept. Our Glass Shrimp (Paratya australiensis) may not be the same as what are called glass shrimp in other countries.

Quote:
Glass shrimp are prolific breeders, breeding all year round. Eggs are held by the female under the tail similar to a yabby. The female nurtures and protects the eggs till they hatch; when they hatch they are planktonic animals that drift in the water column until they grow and moult into miniature glass shrimp. Shrimp breed by the millions, just 200 breeders released into a new farm dam is enough to start the process and that dam will always have shrimp as a food source for your fish.

Glass shrimp are highly fecund, fast growing and highly nutritious. Shrimp are an essential addition to any farm dam.

They are very similar to the "Brown" or Brazilian Gulf shrimp as far as taste and texture. They just require 2 square feet per animal of bottom surface area. A fellow who growes and sells the larva from texas got around that by putting net that resemble shelving in the pools quatdrupling the bottom surface area enabling for higher intensity.
