Macrobrachium rosenbergii, also known as Giant river prawn, Giant freshwater prawn, Malaysian Prawn, Freshwater Scampi, & Cherabin. Prawn is basically a common name for a large freshwater shrimp or jumbo freshwater shrimp. Prawns will work great in your aquaponics system because they will eat organic waste such as dead roots, flies, or anything else that has sunk to the bottom of your tank to decay.

Shrimp farms depend on staggering amounts of antibiotics, fungicides, algaecides and pesticides that pollute the water and other marine life. Here at Liveaquaponics.com we are proud to sell you Hormone Free, Disease Free, and GMO Free Live Prawn's. Shrimp is America's favorite seafood, so adding our live Freshwater Prawn to your system let's you know exactly what is in the food you are eating.

Freshwater Prawns In Your Aquaponics System

Freshwater prawns will make a unique addition and increase the efficiency of your aquaponics system. Prawns are hardy, easy to grow and a highly valued product.

Freshwater prawns consume detritus, thereby helping to break down and convert organic matter into material that can be used by plants. They also eat snails and can be used to control or eliminate them in aquatic systems. Tropical freshwater prawns will survive water temperatures between 57° F and 105° F, with the optimum temperature range being 78° F to 88° F. While freshwater prawns live as long as three years, you can begin to harvest large prawns as early as six months of age.

Freshwater prawns are a tropical animal, and require warm water to survive. A correctly engineered, constructed and well managed pond will result in a predictable harvest of about 1000 - 1200 pounds/acre of a large, highly valuable 10 count/lb. whole shrimp.

Growing Freshwater Prawns

Juvenile prawns can be incorporated into the grow-out system of your choice, and will take approximately four months to mature to harvest size in your aquaponics system. As these juvenile prawns grow, their requirements for space also increase (large prawns weighing 2oz. will have a body length of seven inches, and will require one to two square feet of space).

Stocking Densities

Post larvae to day 45: Up to 40 animals per square foot.

Post larvae to day 60: Up to 20 animals per square foot.

From day 60 to day 90: No more than 2 animals per square foot.

After day 90: One to two and one-half square feet per animal.


If feed accumulates on the bottom of tank, reduce the amount of feed. If there is no feed on bottom of tank increase the amount of feed. DO NOT OVER FEED.

Water Quality

Maintain water temperature of 78-84 degrees F.

Keep ammonia (<2.0ppm), nitrite (<0.05) and nitrate (<40ppm) as low as possible.

PH 7.0 to 8.5, total water hardness min. 40ppm max. 250ppm.
