Biorock Technology: A Novel Tool for Large-Scale Whole-Ecosystem Sustainable Mariculture using Direct Biophysical Stimulation of Marine Organism’s Biochemical Energy Metabolism
Biorock mariculture technology is a novel application of marine electrolysis, which grows solid limestone reefs of any size or shape in seawater, that get stronger with age and are self-repairing. Biorock reefs can be designed to provide habitat speciﬁc to needs of hard and soft corals, sponges, seagrass, ﬁshes, lobsters, oysters, giant clams, sea cucumbers, mussels, and other marine organisms of economic value, or grow back severly eroded beaches at record rates. Biorock reefs, and surronding areas, have greatly increased settlement, growth rate, survival, and resistance to severe environmental stress from high temperatures, sedimentation, and pollution for all marine organisms observed. This allows marine ecosystems to survive otherwise lethal conditions and be regenerated at record rates even in places with no natural recovery. These remarkable ﬁndings seem to result from weak electrical ﬁelds poising the membrane voltage gradients all forms of life use to generate biochemical energy (ATP and NADP), causing enhanced growth of all species. Biorock technology provides a new paradigm for whole-ecosystem sustainable mariculture that generates its own food supplies, the antithesis of conventional mono-species mariculture dependent on external food inputs, whose wastes cause eutrophication that kills off surrounding subsistence ﬁsheries. Potential applications include ﬁsh, crustacean, and bivalve mariculture, algae mariculture, pharmaceutical producing species, and ﬂoating reefs for pelagic ﬁshes. The power requirements are small and can be provided by solar, wind, ocean current, and wave energy. The techniques are ideally suited for community—managed mariculture, if investment funding were available to subsistence ﬁshing communities.
Thomas J.F Goreau was educated in Jamaican schools and hold degrees from MIT, Caltech, and Harvard. President and founder of The Global Coral Reef Alliance, he has dived on coral reefs across the Caribbean, Paciﬁc, Indian Ocean, and SouthEast Asia for more than 60 years. He has published more than 150 papers and written and edited books on scientiﬁc photography, marine ecosystem restoration, and soil fertility restoration. He is co-inventor of the HotSpot method for predicting coral bleaching from satellite data and of the Biorock method for regenerating marine ecoystems and eroding coastlines.
GCRA assessed coral health, algae, and water quality all around Boracay in 1997 and 2007, and made recommendations on tertiary sewage treatment to recycle waste nutrients on land and keep them off the reef. The first report was banned by the Minister of Tourism, and both were ignored.

Philippines to temporarily close popular tourist island Boracay
5 April 2018
Boracay is popular with foreign and local tourists
The Philippine island of Boracay will be closed to tourists for six months following concerns of damage to its once pristine shores.
A spokesperson for President Rodrigo Duterte said the closure would begin on 26 April.
Earlier this year Mr Duterte said Boracay was turning into a “cesspool” and threatened to shut it down.
The island, known for its white-sand beaches, attracted nearly 2 million visitors last year.
The decision has prompted concern for the thousands of people employed in Boracay’s busy tourist trade.
The island is home to around 500 tourism-related businesses, which drew in annual revenue of $1.07bn (£760m) last year. The government said affected companies will receive financial aid.
It’s not clear how the shutdown will be implemented, though the department of trade and industry had earlier proposed closing the island down in phases, saying a total shutdown would be detrimental to businesses and livelihoods.
The move follows growing concern over the island’s environmental health.
Officials had warned businesses had been releasing wastewater into the surrounding waters.
In February, Mr Duterte condemned the island’s hotels, restaurants and other tourist businesses, accusing them of dumping sewage directly into the sea.

“I will charge you for serious neglect of duty [for] making Boracay a fishpond or a sewer pool,” Mr Duterte said at the time.
“Either [you] clean it up or I will close it permanently. There will be a time that no more foreigners will go there.”
The lawsuit by Centro de Incidencia Ambiental (CIAM) against dredging that would damage coral reefs in front of the Panama Canal (based on GCRA reef surveys with the Galeta Marine Laboratory) was admitted by Panamanian Courts on 8 January 2018. This means that the construction works in the port must be suspended while the Court provides a final merits decision. Because we filed an amparo de garantías action, we argued infringement of the constitutional rights to a healthy environment, sustainable development and health. Because of these arguments, once this type of lawsuit is admitted it immediately suspends the legal effects of the resolution that approved the project’s EIA until a final decision is made by the Supreme Court.

March 31 2017, To: NYS DEC Commissioner Basil Seggos State Senator Tony Avella
New York City Department of Environmental Protection is racing ahead with irresponsible plans to destroy the most successful oyster, mussel, and salt marsh restoration project ever done in New York City, or anywhere else.
These projects, approved by New York State Department of Environmental Conservation, have for 10 years pioneered new methods for restoring these valuable ecosystems, providing habitat for birds, fish, and shellfish, protecting shores from erosion, and improving coastal water quality, which could save the City billions of dollars in adapting to and mitigating global warming and global sea level rise (please see current photos attached).
The MacNeil Park projects have shown for the first time how to restore vibrant marine ecosystems to barren shores where everything had died from toxic waste dumping at the site for more than 50 years. They not only restored life to a wasteland, but showed for the first time how to grow these organisms under extreme stress conditions that they normally could not survive. Our team is now expanding the project to fill in all the gaps.
10 years of work will be destroyed if DEP puts the storm drain where they intend. This will not only flush water shown by chemical analysis to have illegally high concentrations of toxic lead, copper, zinc, hydrocarbons, and untreated sewage, but the water flow will wash away the beach sediment and cause severe local coastal erosion at a site that is a designated public recreational area and entry way for kayaks.
Using the Biorock restoration method, we had 100% survival of oysters during the winter when 93% of control oysters died. The few surviving control oysters stopped growing in winter, and their shells were chalky, crumbly, and dissolving due to cold acidic water, but Biorock oysters grew all winter, and their shells were bright and shiny with no dissolution.
The Biorock restoration method has grown salt marsh lower in the intertidal zone than salt marsh grass can tolerate, it grows taller, faster, greener, and spreads faster than controls, grows back in larger spreading patches after every winter when controls die, and has prolific root growth and mussel populations which bind sediment and prevent erosion by waves.
The mussel growth has been so extraordinary that in a few years we have raised the height of the beach where we are growing them by up to a foot, much faster than the rate of global sea level rise, about an eighth of an inch a year. Therefore, we are able to grow beaches upwards at places where they are now washing away from erosion.
Oysters have spontaneously settled near our projects, but not away from them, showing that oyster settlement is increased by the Biorock process. These oysters have shown exceptionally high growth and survival.
These incredible results show for the first time that it is possible to extend salt marshes seaward to protect coasts from erosion. All salt marshes in the US are rapidly eroding and collapsing into the sea due to global sea level rise and increased storm wave strength caused by global warming. Jamaica Bay is the worst example of this. The methods pioneered at the McNeil Park project could save Jamaica Bay salt marshes, and help protect Kennedy Airport from flooding by the sea and storm surges (remember Sandy!).
This destruction of a historic restoration project is entirely un-necessary! There is an existing storm drain at the site that runs out past the project to the low tide mark, built long ago to prevent contaminated water washing directly onto the beach. But instead of using it or upgrading it, DEP plans to dump polluted water directly at the shoreline high tide mark, and flush away 10 years of extraordinarily successful work with polluted water!
The bulldozers are right at the edge of the project, ready to move into action unless DEC can get them to responsibly act to save New York City’s precious green shorelines! We urgently appeal for your help to save the projects that will make New York the leader in natural shore protection.
