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 (PLs) from a hatchery in Florida.  We started with a one horse pump syste, six 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 that we were the 3rd privately owned in the country.  The two privately owned farms that preceeded us were started in Maryland (which has now moved to another state) and the other was also in Indiana!

What made us so unique is that 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.  


Using the one-horse power pumps when we first started, we didn't get the production we had hoped for, so that lead us to experiment with different variables.  Two years ago, we developed a system that runs on air only without the use of any pumps (the only "pump" we use is a regenerative blower to bring air from the outside to run inside the tanks to oxygenate the water and keep the bacteria circulating.) 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 true natural environment; the natural environment without the toxins and pollutants that are in the ocean at this time.  In order to maintain these higher survival rates, we run 9 tests everyday on the shrimp and the water so they can be “happy shrimp” and grow for us! Our system is pretty basic, and it works! The hardest part is being patient and allowing that bacteria to grow to maintain the shirmp, but this is why we are diligent about testing! 


We have been able to maintain the bacteria for 6 years. 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're do their own thing. 


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. 



Our Team

Darryl & Karlanea Brown- Owners



Darryl and Karlanea are the husband/wife duo that run RDM Aquauculture. Darryl, as the "Guru of the Water," has a degree in Agriculture and Animal Science from Purdue University. Starting by raising hogs then looking into tilapia, he got into researching and then raising shrimp for over 6 years. He is very dedicated to improving the shrimp industry. Darryl is continuously researching and looking for a better way to raise shrimp in the heterotrophic system!


Karlanea is the VP of Operations. She has over 6 years of experience in the RAS and heterotrophic systems. With the 90% survival rates, Karlanea is in charge of not only making the shrimp happy, but helping make you into a succesful shrimp farmer!


In Loving Memory of Russ and Marie Brown.


Russ and Marie (the R & M in RDM) helped start the farm. Both are passed away but we are forever grateful for their assistance in starting the farm! You are dearly missed!
