But most cosmopolitan seafood consumers don’t know much about it. Unlike whiteleg shrimp and tiger prawns, GRPs have yet to become mainstays of the global seafood industry. Most of the animals spend their time feeding instead of fighting – shortening production time while improving productivity.”, “Size definitely matters – male GRPs grow significantly larger than females and all-male batches produce fairly uniform-sized prawns which sell for more than whiteleg shrimp or tiger prawns. Freshwater prawns will make a unique addition and increase the efficiency of your aquaponics system.
