Just read a Farm Show article (Vol 35, no 5, 2011) called "Indianans develop a taste for freshwater shrimp." Keith and Katrina Henderson have 5 shrimp ponds, which they just introduced crabs to this year. Each
pond gets 300-450 lbs shrimp per year (sold at $12/lb!) They put juvenile shrimp in each June, stocking about 10,000 per
pond (high mortality). They
feed, and monitor the pond's pH, temperature, and oxygen levels daily. Over Labor Day weekend, they drain the ponds, and the shrimp have grown to 12 per lb. They harvest then to avoid a possible frost. Freshwater shrimp have a lobster texture, and many who are allergic to marine shrimp can eat these. They have to make sure the aerators run constantly, and they have to trap some predators, like turtles and frogs.
