To develop Macrobrachium rosenbergii (de Man) culture in French Polynesia, a high density larval rearing method in clear water for post‐larvae mass production has been set up by the “Centre Océanologique du Pacifique“. Based on three years of experiments, a production of 60 postlarvae per liter in 800‐liter tank was obtained. The methodology (conical bottom tank, static system with one total daily water exchange, no phytoplankton), the environmental conditions (temperature, light, color of the tank), the water quality control (chlorination, antibiotics, aeration), the larval food (quality and quantity) are given and discussed. The model was used to build a hatchery on a pilot scale (capacity 600,000 post‐larvae every 2 month). Due to a high level of control of the system, this method could be used in any environment.
