Postlarvae of the cauque prawn Macrobrachium americanum were reared for 4 months under laboratory conditions at 20°C and 33°C. Four hundred 50‐d‐old postlarvae were stocked into eight 70‐L aquaria. A balanced commercial feed containing 40% protein was supplied daily at 9–20% of body weight during the first 2 months and at 3–5% of body weight during the final 2 months. Live brine shrimp Artemia spp. were also provided as food. The growth of the cauque prawns was greater at 33°C than at 20°C but did not differ significantly over the study period. Knowledge of cauque prawn rearing requirements under artificial conditions is important for the production of juveniles as stock for large‐scale prawn culture.
