Treating catfish

We have spent the past 17 years developing ways to analyze the aquaculture practices from the farm level to the retail level. We currently maintain laboratories around the world that are testing new ways to improve the growth and health of multiple aquacultured species. We are also working with market partners who communicate to 100’s of millions of people annually about seafood. Let us know your problems and lets work together to solve them. Every business faces challenges; let us be your partner in finding solutions to increase your profits.

Independent studies of the GroFish™ process have been done at: University of Missouri-Columbia on Rainbow Trout, University of Missouri-St. Louis on Channel Catfish, Harbor Branch Institute of Oceanography in Florida on clams, shrimp and clownfish, University of Umea, Sweden on Salmon, and USDA Warm Water Research Labs in Mississippi on Channel Catfish.

GroFish™ Commercial research has been done in Chile on Salmon, China on Shrimp, Carp, Sea Cucumber, Grouper and Tilapia, Norway on Trout, Sweden on Trout, Mexico on Shrimp, Vietnam on shrimp, India on shrimp, Mexico on shrimp, Panama on shrimp, and USA on Prawn, Shrimp, Catfish, Carp, Bass and Trout.

Current research includes feed formulation studies, new species including coral, and filtration experimentation for nitrate, nitrite and ammonia reduction in closed systems.

As a testament to GroFish, LLC’s proven methods and our exclusive GroFish™ technology, a study was done at Lyons Fisheries Prawn Farm, the largest prawn farm in the state of Illinois. They participated in a field study to determine if prawns treated with GroFish™ and fed treated feed would grow faster and bigger than prawns that were not treated.

Study at Lyons

In a presentation made on October 18, 2007 to the Shawnee Prawn Growers Association of Illinois hosted by the University of Illinois-Carbondale Extension Office, Brenda Lyons discussed:

The GroFish™ Treatment at the nursery stage:

  • 8,583 post larvae were treated 5/6/2007
  • Post-larvae were @ PL 12-15
  • Post-larvae were kept in their own recirculating system (Test Tank)
  • Post-larvae were fed a diet of treated feed
  • They were kept in the nursery for another 27 days before being stocked in the production pond.


  • A Control Tank was set up in the nursery with like conditions
  • Same water, same temperature, close stocking density
  • The Control batch was fed untreated feed
  • Production ponds were stocked on the same day
  • The Control pond was fed the same feeding schedule as the Test Pond

Data collection:

  • Samples from both ponds were collected sporadically with the use of the cast net
  • The samples were weighed and measured using the same amount of samples with each collection
  • Data was maintained and pictures taken for reference
  • The health and quality of the animals were observed in both production ponds


  • The test prawns seemed more active and grew to a larger size in the nursery thus stocking a larger juvenile
  • Samples revealed that faster and larger growth took place using the treated feed
  • The treated prawns yielded less runts, but did have some smaller size also
  • The quality and overall health of the treated animals was definitely noticeable


  • Harvested 303 lbs of prawns from the Test pond, 201 lbs from the Control pond
  • The GroFish™ prawns were noticeably larger than the untreated prawns
  • Overall GroFish™ productivity in Test Pond was 151% over Control Pond
  • Survival was good in the Test pond
  • The Gain to Feed ratio was 63 %
