Freshwater prawn (Macrobrachium rosenbergii), also known as the giant river prawn and giant tiger prawn, is a close relative to marine shrimp. They are one of over 950 species in the Palaemonidae family. Freshwater prawn males can reach a total length of 12.6 inches (320 mm); females 9.8 inches (250 mm). Their long and slender claws (chelipeds) are blue or orange in color. Their shell (exoskeleton) turns pink when cooked. Freshwater prawns are known for having succulent tail meat with a firm, lobster like, texture and sweet flavor.

Where do the freshwater prawn I eat come from?
Macrobrachium rosenbergii are tropical crustaceans native to Malaysia. They are commercially harvested from the wild and have been introduced to every continent, except Antarctica, for the purpose of commercial farming. In the US, freshwater prawn are commercially farmed in the Midwest, the South, and Hawaii. The freshwater prawn industry is small, making up less than 1% of annual domestic aquaculture production. In 2018, 45% of farms that reported raising freshwater prawn to food size, were located in the Midwest. Freshwater prawn are commonly raised in ponds and sold fresh, with heads intact, from the farm, at local farmers markets, and Asian markets. Midwest farm-raised freshwater prawn are typically sold seasonally—in early fall.
