With the consumption needs of an increasing world population putting greater stresses on environmental sustainability, there is a challenge of how to balance demand with supply.

Fishing experts project global aquaculture production will need to more than double in the next 40 years to feed the close to 10 billion people by the year 2050.

These same experts say there are many threats to fishing from the ocean, including overfishing that has reduced fish populations in some cases to the point of extinction. Industrialization has led to heavy metals pollution of the oceans. Plastic breakdown has infested marine life with micro-plastics.

The challenging scenario is one Pure Blue Fish U.S. founder and Chief Executive Officer Nimrod Litvak is addressing head-on and a key focus on the solution will be based in Orangeburg County.

Litvak founded Pure Blue Fish, a fish farming company, about four years ago in Tel Aviv, Israel, to grow yellowtail fish.

The raising and eventual harvesting of the fish include recirculating aquaculture systems with zero-water discharge technology. The technology reduces water costs and pollution.

Litvak announced the company will invest $28.1 million to open its flagship U.S. operation in Orangeburg County at the John W. Matthews Jr. Industrial Park. The company will create 82 new jobs.

"Unlike most intensive aquaculture systems, our technology treats the water with biological and microbiological subsystems that enable our system to function at top efficiency without discharging polluted water, or any water, to the environment," Litvak said.

The Blue Fish system Pure Blue’s Zero-Water Discharge Recirculating Aquaculture Systems (RAS) Technology was developed by Professor Jaap van Rijn of the Hebrew University of Jerusalem in Israel.

RAS is a touted as a new way to farm fish in a safe, productive and sustainable way.

Instead of the traditional method of growing fish outdoors, this system raises fish at high densities in a "controlled" environment typically indoors.

The technology allows farmers to control environmental conditions year-round.

The technology removes the fish waste through converting ammonia to nitrate, converting nitrate to nitrogen gas, which evaporates; and converting organic-rich sludge and fish waste to a gaseous phase.

The processes provide a healthy environment for freshwater and saltwater aquaculture and minimize the discharge of waste.
