In the quiet farmland of Benton County, where rows of corn stretch as far as the eye can see, there’s something swimming just beneath the surface – literally. Inside a modest building on the edge of Fowler, Indiana, the Brown family is raising fresh, saltwater shrimp. RDM Aquaculture is one of the most unexpected and innovative operations in the Hoosier heartland.
A Sea Change in the Heartland
Darryl and Karlanea Brown never set out to be shrimp farmers. Back in 2010, they decided to take a leap of faith, turning a dream into what would become one of the first indoor shrimp farms in the country. At the time, the idea of farming ocean shrimp hundreds of miles from the nearest coastline seemed far-fetched. But the Browns believed they could make it work and they did.
Using a recirculating aquaculture system, RDM Shrimp raises Pacific white shrimp indoors in carefully monitored saltwater tanks. Every day, Karlanea checks and records water quality levels including salinity, oxygen, and pH to keep the shrimp thriving. There are no antibiotics or chemicals, just clean water, good feed, and lots of care.
Fresh Shrimp, Hoosier Made
The shrimp at RDM start their journey as tiny larvae shipped in from Florida or Texas hatcheries. Once they arrive in Fowler, they’re nurtured in nursery tanks before being moved into larger grow-out systems where they’ll reach full size in just a few months.
Unlike grocery store shrimp that have often been frozen and shipped thousands of miles, RDM’s shrimp are sold fresh and alive, right from the tank. Visitors can walk into the farm, choose their shrimp, and take them home – heads, shells, and all. The Browns say keeping the shrimp whole not only proves freshness but enhances flavor when cooked. Needless to say, customers agree. People drive from as far as Chicago, Indianapolis, and even Michigan to get their hands on these sweet, sustainably raised shrimp. For many, it’s the freshest seafood they’ve ever tasted without a trip to the coast.
Tours, Education, and Innovation
Beyond just selling shrimp, RDM Aquaculture has become a learning hub for other farmers and curious visitors alike. The Browns offer tours that range from quick 20-minute visits to in-depth, hands-on “discovery tours” that explore the science behind shrimp farming. School groups, agriculture students, and curious Hoosiers often stop by to learn how saltwater shrimp can thrive in a landlocked state. Their sustainable approach has also earned them recognition. In 2015, RDM received an Indiana Innovation Award, celebrating their pioneering work in recirculating aquaculture systems and clean, environmentally friendly farming.
Shrimp with a Side of Sustainability
What makes RDM’s story even more impressive is its environmental focus. The Browns operate a zero-exchange water system, meaning the same water is continuously cleaned and reused instead of being drained and replaced. This not only conserves resources but helps protect nearby waterways.
By raising shrimp indoors without chemicals or antibiotics, RDM helps reduce pressure on overfished oceans while giving Midwesterners a sustainable source of seafood. It’s local, eco-friendly, and fresh – a rare combination that’s changing how people think about farming.
A Hidden Gem Worth the Drive
It’s not every day you stumble upon saltwater shrimp in the middle of Indiana corn country, but that’s exactly what makes RDM Shrimp such a hidden gem. It’s a place where farming meets science, and where a dream born far from the ocean came to life – a testament to Hoosier creativity and hard work.
So next time you’re near Fowler, swing by RDM Aquaculture. Take a tour, meet the Browns, and maybe bring home dinner fresh from Indiana’s very own “sea.”
