This project will build large areas of artificial habitat that will create millions of tonnes of new fish

Explain your project idea (2,000 characters)
We are working on a project in Malaysia to create large-scale artificial reefs which will rebuild fish habitat in tropical waters
This will help
The Ocean Environment
and Reduce Regional Tensions
25-hectare squares of depleted seabed will be rejuvenated with concrete reef blocks, sections of old oil platform and other fish-friendly habitat.
These squares will in effect create mini marine protected areas.
The squares will be laid out in a pattern over large areas of seabed with lanes in between that can still be trawled.
The squares will allow fish stocks to recover on areas of seabed that have been denuded by trawling, and the lanes will allow large-scale fishing to continue without destroying the source of the fish.
This hybrid approach avoids the clear-cutting / strip mining of conventional trawling and concentrates fishing in areas where it can be more closely managed.
It has been shown that man-made structures such as oil platforms can be 20 times more productive than natural reefs in equivalent areas (Claisse et al).
This multiplier will also apply in the Ocean Orchards by laying extensive areas of fixed Fish Aggregating Devices, providing a low cost equivalent to the vertical habitat of the oil platforms.
Arrays will be installed in relatively shallow water, 10m-30m, where sunlight can drive the food chain.
In the long term, many thousands of km2 will be laid out across the South East Asian Seas, producing millions of tonnes of new fish.
A demonstration site has been selected in Malaysia which will incorporate an existing rig-to-reef location.
Arrays of concrete reef blocks and Fish Aggregating Devices will be built around the rig section. This trial will determine optimal design, quantify the species and productivity created by the habitat.
Learning will be applied to planned rigs-to-reefs activities to ensure that the largest, most productive arrays can be built at the lowest possible cost
Who are the beneficiaries? (1,000 characters)
The first line beneficiary of the Ocean Orchards project is the Malaysian fishing community
The new areas will allow more fish to be caught in less time in better controlled zones.
This fishing will also be sustainable, as only a limited amount of fish can be removed at any one time, maintaining the base population and preventing the ‘strip mining’ that takes place at the moment
South East Asian fisheries are heavily extracted, as shown by the collapse in catch rate in Thai waters, from 300 kg/hour down to 20 kg/hour
This results in ‘Fishing Down the Food Chain’ where progressively smaller fish are caught and stocks collapse
For Ocean Orchards operators, who might be communities, cooperatives, businesses or other groups, this has potential to be a self funded steady, large scale, profitable business
The wider community will also benefit from the continuing and eventually increasing availability of good quality wild fish
Bycatch will also sustain regional aquaculture

How is your idea unique? (1,000 characters)
This idea brings together observations from artificial reefs, offshore structures and fish aggregating devices to make a new type of open ranch system for fishing.
This idea has been enthusiastically received by the marine biology community who are eager to see the results of the trial.
Nothing on this scale has been tried before.
Large numbers of small scale artificial reefs have already been built around the Coral Triangle / ASEAN area. In Thailand alone some 2,000 km2 of artificial reefs have already been built. There are 181 artificial reefs in Malaysia, and these are prolific sources of fish
Usually Inshore artificial reefs are built to keep trawlers out and to help artisan fishermen. Trawlers would benefit from artificial reef type habitat designed specifically to meet their needs.
The Ocean Orchards approach will build habitat that has vertical height, amplifying the productivity of artificial reefs while better protecting them from trawling.
Idea Proposal Stage (choose one)
Pilot: I have started to implement the idea as a whole with a first set of real users.
Tell us more about your organization/company (1 sentence and website URL)
This project is proposed by a team of three groups working together
- Steve Willis - Originator of the Oceans Orchards concept
- T7 Global - Offshore industry service specialists who have already installed a Rigs to Reefs project.
- Reef Check Malaysia - A worldwide NGO that surveys the condition of coral reefs.
Reef Check are a well established NGO in Malaysia, and would be the conduit by which external funds can be deployed in Malaysia.
Organization Filing Status
Yes, we are a registered non-profit.
In 3-4 sentences, tell us the inspiration or story that encouraged you to start this project.
In my first job I worked alongside tough Grimsby trawlermen. They were immensely proud of their heritage, but by 1986 they were working with me in the chemical industry because the fishery had collapsed.
15 years later I visited an oil platform in Indonesia and was astonished to see the huge cloud of fish that lived around the structure.
It struck me that if the same effect could be duplicated a thousand times, and then a thousand times again, the collapsed fish stocks could be rebuilt.
Please explain how your selected topic areas are influenced, in the local context of your project (1,000 characters).
IUU fishing, Illegal, unreported and unregulated fishing are a significant cause of regional tension in South East Asia.
This is primarily caused by collapsing fish stocks combined with growing demand. Indonesia has started seizing and sinking encroaching boats from China and Vietnam
Prosperity in the fishing communities around the region suffers because of collapsing fish stocks.
Modern day slavery is a known issue on fishing boats in this region
The planet suffers as the Seas of South East Asia are repeatedly trawled and valuable habitat degraded.
Biomass levels have plummeted as tighter nets are used to catch smaller fish and the next generation of fish are caught before they have chance to breed
Who will work alongside your organization in the project idea? (1,000 characters)
Reefcheck will be the NGO part of the team
T7 will supply the project management expertise to procure the materials and install the demonstration site
The Department of Fisheries and local Universities are also already involved
Please share some of the top strengths identified in the community which your project will serve (500 characters)
Malaysia is blessed with large areas of relatively shallow, tropical waters which have the potential to be very productive. It is the ideal location in which to develop purpose built, large scale fish ranching sites to encourage the growth of fish which can be caught by conventional fishing boats.
Malaysia also has a strong entrepreneurial base which can develop new industries. The aim would be to build a self funding Ocean Orchard fishing industry and for other ASEAN countries to do the same
Malaysia and neighbouring ASEAN countries initially
How many months are required for the project idea? (500 characters)
With funding, installation of this project could start within 6 months.
Once the demonstration site is in place, regular monitoring will take place to assess the performance of the Ocean Orchard site.
After 18 months or so, the next stage will be built as part of Rigs to Reefs or similar projects in the region.
Learning from each round of evolution will be applied to future installations
