In Ha Loc, a fishing village in Da Nang in central Vietnam, a 34-year-old man who had been an oilfield engineer earning over 100 million dong a month quit his job and returned to the sea of his hometown. What he protects is the 64-hectare Ba Dau coral reef. A team of more than 40, formed of fishermen and the border guard, patrols every month, steering from a sea where fish are caught to a sea where fish are raised. Behind it lies a single line: 'without a stable livelihood, people do not truly understand the meaning of environmental protection.' This does not end as a feel-good story. For Japanese buyers sourcing seafood and for agriculture-and-fisheries people who are beginning to be asked about an origin's sustainability, it is an on-the-ground story rich in implications for sizing up a source.
How an oilfield engineer returned to his hometown sea
The protagonist is Vo Hong Ron, 34. Local reports say he worked at an oil and gas company from 2014 to 2017 and earned over 100 million dong a month. Converting at roughly 1 yen to 170 dong, that is a scale of about 580,000 yen a month-exceptional treatment for someone from a rural fishing village. Even so, he resigned, sold his own fishing boat for 100 million dong, and moved to the side of pouring funds and time into regenerating his hometown sea.
The turning point was the sea's degradation. Overfishing, litter, and disorderly fishing battered the coral, and fish dwindled. From 2020 to 2022, Ron led as many as 40 beach cleanups, hauling what is said to be hundreds of truckloads of waste off the shore. At the same time, he launched the area's first seaside homestay and later opened an eatery called 'Blue Whale.' From fishing to tourism, he first moved his own livelihood to show the way.
The concreteness of 'protecting 64 hectares'
The Ba Dau coral reef spreads in the East Sea (the South China Sea) off the Ha Loc fishing village in the Tam Xuan area of Da Nang City (formerly Tam Tien, Quang Nam province). It is about 40 km from Hoi An. The protected area is 64 hectares, with coral cover reported to average around 30 percent. It is a sea where the reef becomes a hiding place for fish and a source of fishery resources.
In October 2022, a co-management team of more than 40 people, including fishermen and the border guard, was launched. Ron serves as deputy leader. The team patrols every month by motorboat, going around the full 64 hectares to monitor illegal fishing and abnormalities in the coral, making the no-fishing zone actually function. The key is not a declaration that 'we will make it a no-fishing zone' but the continuation of an operation in which people take boats out and patrol every month.
Comparing with the pioneering models of Quang Nam and Da Nang
This effort is not a mutation. In the same central region, the Cu Lao Cham marine protected area off Hoi An is known for roughly 20 years of co-management. Resident-participatory management improved the condition of the coral reef, and amid a low share of Vietnamese coral reefs rated as being in good condition, this protected area has been reported as one of a few fine examples. Many residents are said to have shifted the axis of their livelihood from fishing to tourism.
| Item | Ba Dau reef (Ha Loc) | Cu Lao Cham marine protected area |
|---|---|---|
| Location | Tam Xuan area, Da Nang City | the islands off Hoi An |
| Protected area | 64 hectares | a wide-area protected zone including islands |
| Who manages it | a co-management team of more than 40, including fishermen and the border guard (since 2022) | resident-participatory co-management (about 20 years) |
| Livelihood transition | early stage, spreading to 20 lodgings and eateries | many residents have shifted to tourism |
There are differences in both scale and history. But the design philosophy of 'residents patrolling the sea as stakeholders' and 'creating income from tourism in place of fishing' belongs to the same lineage. The Ba Dau reef is reproducing that microcosm at a new site.
How the ground and the industry take it
Within the fishing village, local reporting hints that there were skeptical voices at first. Turning a sea that yields catch into a no-fishing zone cuts near-term income. That is precisely why Ron sold his own boat and first showed concrete examples of alternative income in a lodging and a shop. His fellow fishermen joined the patrol team because they came to feel that protection is not an enemy of livelihood but a premise for it.
The response from tourists is also a tailwind. It is reported that 20 lodging facilities have sprung up in Ha Loc, which has come to accept guests on the scale of several hundred. The coral reef as a resource itself becomes a draw, and a cycle in which the more the sea is protected the more guests come has begun to turn. Among researchers too, co-management that raises residents' awareness and participation is drawing attention as a practical solution for coral-reef conservation in Vietnam, and the Ba Dau case is situated in that context.
Across Vietnam as a whole, 11 of the 16 designated marine protected areas were said to be established as of June 2025, and the policy current of reconciling protection with tourism and responsible fishing is strengthening. Ba Dau, in that it began not from a top-down protected-area designation but from a small, resident-originated self-governance, can be called a case that complements that current.
Implications for Japanese seafood buyers and origins
Consume this as a 'nice story' and you miss the essential implications. There are three points at issue for Japanese fisheries people.
First, the yardstick for measuring a source's sustainability is changing. Japanese buyers handling Vietnamese seafood have entered an era of being asked, on top of price and quantity, how the origin manages its resources. Certifications such as MSC (the sea eco-label) and ASC (its aquaculture version) are mechanisms that secure traceability from catch to product, and labeled products are increasing year by year in Japan too. Resident-originated management like Ba Dau's is not certification itself, but it is a movement that accumulates in the region the 'actual state of resource management' that certification audits presuppose. When choosing a source, grasping such regional efforts lowers future sourcing risk.
Second, an origin's story becomes the basis for pricing. Ron's coral reef and homestay are designed to leave the added value of tourism in the region. Just as origin labeling and the grower's face carry sales value in Japan, Vietnamese seafood and produce become easier to differentiate the more they can tell 'what kind of sea or field they were protected as.' If an import buyer grasps the local conservation story, it can be carried straight over into domestic product planning and label messaging.
Third, it serves as a reference as a model of community-building that connects tourism with primary industry. Against the successor shortages and resource decline that Japan's fishing and farming villages face, the idea of widening the pillar of livelihood into tourism to create conservation incentives for the stakeholders also connects to regenerating domestic origins. As a nearby Vietnamese case, in Quang Ninh province a producer who achieved year-round shrimp farming and the move taking on the revival of black tiger shrimp in Ca Mau are also in the same current of trying to reconcile production and environment.
Ripple effects on the market and industry
Coral-reef conservation is directly linked not only to tourism income but also to the regeneration of fishery resources. The 'spillover effect,' in which the reef becomes a nursery for juvenile fish and catches recover around the no-fishing zone, has been reported in many places. Even if income falls in the short term due to the fishing ban, in the medium term the catchable fish return, and in the long term tourism takes root. Ba Dau is still at an early stage of transition, but whether it can run this time-axis design at the fishing-village level will be the dividing line.
It also cannot be ignored from the export-market standpoint. Vietnamese fisheries are at a juncture of reviewing the composition of their major export destinations, and the move toward a shift to China-bound exports is also reported. Supporting export competitiveness on price alone is becoming difficult, and resource management and traceability will become the next axis of competition. If resident-originated conservation spreads across regions, it could lift the 'sustainability brand' of Vietnamese seafood as a whole. The earlier the Japanese sourcing side grasps that budding, the more advantageous it is.
Practical information and related links
The Tam Tien area where the Ba Dau reef lies is included in the region where Quang Nam province was merged into Da Nang City in July 2025. Because the address notation has changed to the new 'Tam Xuan area, Da Nang City,' when researching the site for an inspection or a deal it is good to confirm it together with the old name, Tam Tien, Quang Nam province. At about 40 km from Hoi An, it is close, making it easy to arrange a field-research route combined with a Cu Lao Cham inspection.
As a premise for discussing seafood sustainability in negotiations, grasping the mechanisms of MSC and ASC certification and their handling status in Japan provides a common language for evaluating Vietnamese origins' efforts. Understanding the relationship in which resident-originated management creates the groundwork for certification raises the precision of origin evaluation.
Summary: the next move
The core of the Ba Dau reef story is that it did not set protection against livelihood but arranged livelihood first and thereby increased the stakeholders in protection. The next actions Japanese seafood buyers and origin people should take are concrete. First, for the items you source from Vietnam, confirm through primary information what kind of resource management that origin practices. Next, position origins with a conservation story as material for product planning and label messaging. And try applying to your own domestic origins the design of 'increasing the pillars of livelihood through tourism and experiences, and nurturing the stakeholders in conservation.' A sea whose value rises the more it is protected is not a story for Vietnam alone.
