ABSTRACT The farming of freshwater prawns ( Macrobrachium rosenbergii ) in geothermal heated water has been demonstrated to be possible in a nontropical climate. The husbandry of prawns is being done in two outdoor raceway ponds 9.1 m by 2.5 m and 29 m by 3.5 m that are 1.2 m deep. The ponds are not shielded from the ambient climate which during the winter months has recorded air temperatures as low as ‐20°C. A select brood stock is held in a small spawning building where larvae are hatched in artificial saltwater and reared to the postlarvae stage, making the facility self‐contained. This project is providing a model for potential investors to utilize the low‐temperature geothermal resources in the western United States for warm water aquaculture of a market‐size prawn.
