NaturalShrimp is moving to buy Hydrenesis Aquaculture, LLC to acquire the company’s innovative water treatment technology. The company, which pioneered recirculating aquaculture systems (RAS) for shrimp production, has signed a letter of intent (LOI) to acquire the aquaculture assets of Hydrenesis for US$12.5 million.

NaturalShrimp “intends to immediately begin deployment of the technology in our hatchery and nursery systems,” Gerald Easterling, chief executive officer of NaturalShrimp said in a press release. “We expect to file additional patents around the expansion of the application and use of the combined EC and Hydrenesis technology.”

Easterling said that the Hydrenesis technology “will have major impacts on disease control” in established and growing aquaculture segments such as salmon, barramundi and tilapia farming.


Hydrenesis’ technology uses a form of reduction-oxidation (Redox) which produces an electro-chemical reaction that reduces harmful metals in water. The technology increases oxygen levels in the water and produces a supportive environment that reduces stress levels in fish and shrimp.

“We have been exploring the application of ‘Redox’ water treatment for several years,” according to David Antelo, CEO of Hydrenesis, Inc. “Our technologies’ ability to affect water chemistry and elevate water quality is proving to have a significant impact on growth and health metrics.”

He said Natural Shrimp is “the ideal partner for extending commercialization of Hydrenesis technologies to additional species applications.”
