Production of freshwater prawns has expanded in the US with some production in >20 states. Two different approaches to reducing production costs have evolved, one based on minimizing input costs and maximizing harvest sizes, the other on maximizing production (kg/ha). Profitability in both is largely dependent on optimizing selling prices by offering product forms which do not face direct import competition (i.e. live, fresh, whole) Prawns have been recognized as one of the most environmentally sustainable aquaculture crops, and attribute which is very appealing in many markets, especially those emphasizing local foods.
