About Us

A shrimp farm in Indiana?  Who would have thunk it? 


RDM Aquaculture was started on July 13, 2010 when we received our first batch of post larval from a hatchery in Florida.  We started with a one horse pump system and 6 production tanks and two nursery tanks.  Since those days we now have 19 production tanks, 7 intermediate tanks and 8 - 10 nursery tanks.  


When we started we thought there were hundreds of these farms across the US.  We did not know we were the 3rd in the country that was privately owned.  When we started in 2010 there was a farm in Maryland (which has now moved to another state) and another one in Indiana.  


What made us so unique is we used a RAS (Recirculating Aquaculture System) using a heterotrophic bacteria based water or ZEAH (Zero Exchange Aerobic Heterotrophic System) or bio flock.  It basically means we do not discharge our water, (ours is 6 years old) and we use a brown water or bacteria base system instead of a clear water system.  


When we started we used the one horse pumps and they didnt produce what we had hoped. So we experimented and didnt want to have equipment breaking down on us or using electricity and giving us a large electric bill.   2 years  ago we developed a system that runs on air only with out the use of any pumps.  (the only pump is a regenerative blower to bring air from the outside ) We now run 100% on air from nature. 


 We are guardians of water and maintain the water in order to get the large survival rates for our shrimp.  We feel that if we take care of the water, the water will take care of the shrimp.  Our water is actually as close to their natural environment with out the toxins and pollutants in the ocean at this time.  In order to maintain this we do 9 test everyday on the shrimp so they can be “happy shrimp” and grow for us.  


We have been able to maintain the bacteria for 6 years and each year it gets better with age and each year our survival rates go up.  We do over 90% survival rate in our nursery and intermediate tanks and we range from 70% - 90% in our production side.  



Using no antibiotics or  hormones are what we are most proud of.  We are getting large survival rates and yet only let nature do her thing.  We just try to maintain her.   We do not work against her or change her.  We have found that most shrimp have not read any of the shrimp books out there and they do their own thing.  


We have designed a system that is pretty basic and works.  The hard part of all of this is getting the bacteria.  It takes one year to build the bacteria up to where it will maintain the shrimp.  This is why we work real hard on the water, by doing 9 test every day to make sure the water is where it needs to be so we can have successful shrimp harvest.  


We do not sell to restaurants or grocery stores at this point, we do 99% retail sales.  Once you try our shrimp you will not want shrimp any other way than from a local farmer.  It has such a clean flavor and much firmer meat that we find else where.  


I am always asked if I would do this again.  Yes I would.  I love every aspect of aquaculture.  I like that we are diversifying by also raising Australian Red Claw crayfish and tilapia.  Getting ready to start an aquaponics system using the crawfish and tilapia.  Hopefully soon we can raise oyster also and have our own hatchery for shrimp.  Have a goal to make Indiana the shrimp capital of the world. 


If interested in shrimp farming  give us a call, we would love to talk to you and get  you set up.  We really want all of our farmers to succeed.  This is not an easy venture.  It takes attention to details and 7 days a week with a minimum of 3 hours a day.  If you thinks this might be for you please give us a call and schedule a tour.
