Vietnamese fishing hamlets are stretching old nylon nets across roads to keep outside trawlers and tourists away from near-shore fishing grounds. These "town nets" are cheap, homemade checkpoints that slow traffic rather than stop it, and they are spreading as climate change and industrial boats push fish closer to the beach.
A Net Across the Road
The first time I saw a fishing net stretched across a town square, I thought it was an art installation. Not the delicate lace of a Victorian widow’s veil, not the tangled ghost gear washed up on beaches, but a full-scale barrier of nylon mesh and bamboo poles, blocking the road at the edge of a village in northern Vietnam. Locals walked around it without blinking. Drivers honked, waved, and kept going. It wasn’t art. It was the “town net,” a temporary checkpoint made of whatever was lying around—rope, wire, old fishing gear—erected by residents to slow down outsiders during fishing season. The idea is simple: keep strangers out, keep fish in, and maybe keep the peace when disputes flare over who gets to cast a net where.
What began as a quiet tradition has quietly exploded into a patchwork of informal borders across Vietnam’s coast. In Quang Ninh Province, nets have become so common that Google Maps now marks them as “local checkpoints.” In Thanh Hoa, residents rigged a 500-meter stretch of nylon mesh between poles to stop outsiders from fishing in their waters. The nets aren’t meant to trap people, only to slow them down. They’re a low-tech barricade in a region where the sea is both lifeline and battleground. But as climate change pushes fish closer to shore and tourism crowds the coast, these nets are turning from folk tactic into flashpoint. Some say they’re protecting livelihoods. Others call them illegal blockades. The government calls them a nuisance. And the nets keep spreading.
What Exactly Is a Town Net?
Town nets are essentially temporary roadblocks made from fishing gear. They’re not built to catch fish, but to catch attention. Most are made from nylon mesh panels, old seine nets, bamboo poles, and sometimes even rusted wire. They’re strung across roads, alleys, or paths leading to the sea, usually during peak fishing seasons or when tensions rise over marine resources. The idea isn’t to trap people but to force them to stop, slow down, and think twice before entering. In some villages, residents take turns guarding the nets at night, especially during squid season or when illegal trawlers are spotted nearby.

The practice has roots in traditional coastal life. For generations, Vietnamese fishing communities have relied on communal fishing grounds and unwritten rules about who can fish where. When outsiders—whether from other provinces or commercial boats—started encroaching on local waters, some villages responded by creating physical barriers. At first, they used ropes or bamboo. Over time, as nylon nets became cheaper and more available, the barriers grew sturdier, more visible, and more controversial. Today, town nets appear in at least six provinces along Vietnam’s 3,260-kilometer coastline, from Quang Ninh in the north to Kien Giang in the south. They’re most common in areas where small-scale fishers say they’re being squeezed out by industrial boats and tourism development. In some cases, the nets are sanctioned by local authorities as a way to enforce informal fishing bans. In others, they’re set up unilaterally, leading to clashes.
One of the most documented cases is in Thanh Hoa Province, where villagers erected a 500-meter net across a coastal road in 2024. The barrier was meant to stop outsiders from fishing in a zone reserved for local boats. Within days, photos of the net circulated on social media, drawing both praise and criticism. Supporters called it a creative act of self-defense. Critics said it violated traffic laws and risked alienating tourists. The provincial government eventually ordered the net removed, but by then, copycat barriers had already sprung up nearby. The story repeated itself in Ha Tinh, Nghe An, and Quang Binh, each time with slight variations: a different color net, a different length, a different excuse. Yet the underlying grievance stayed the same—people felt the sea was being taken from them, and they were willing to block a road to make their point.
Why Now?
Climate change is shrinking the distance between the shore and the fishing grounds. As surface waters warm, many species move closer to cool, nutrient-rich coastal zones. This sounds like good news for small boat captains who can’t travel far, but it also means industrial trawlers hug the coastline, scooping up everything in paths wider than a football field. Satellite tracking data show that large vessels now operate within five nautical miles of the beach in several provinces, well inside the three-mile buffer meant for artisanal gear. The result is a daily collision of interests: local fishers return with near-empty baskets, while refrigerated trucks wait on the pier to load tons of by-catch headed for fishmeal plants.
Tourism adds another layer of tension. Coastal provinces have raced to build resorts, sometimes filling in mangroves or seagrass beds that serve as fish nurseries. A single five-star hotel can alter currents enough to shift sandbars, changing where boats can safely anchor. Homestay booms in places like Cat Ba or Cam Ranh bring waves of weekend anglers who rent cheap rods and drop lines straight off the pier. They rarely follow the lunar calendars that locals use to avoid spawning seasons. When hotel security guards tell villagers they can’t launch boats beside a new jetty, the reply is often a net across the only access road.
Rising fuel prices push even lawful captains toward gray areas. A trawler captain from Thua Thien Hue explained that steaming an extra twenty nautical miles to respect the buffer zone costs an additional 18 million dong per trip, nearly erasing profit. Rather than absorb the loss, some pay modest bribes to local officials, or simply fish at night when surveillance is lighter. Coastal residents know the dance. When they spot deck lights clustering too close, they reach for the cheapest deterrent they have: an old net and two bamboo poles.
Voices from Both Sides of the Mesh
Nguyen Thi Hoa, a 62-year-old grandmother in Tinh Gia district, keeps a small coffee stall beside the road where a town net appeared last spring. She saw the men erect it at dawn, using headlamps to tie knots in the half-light. “They didn’t ask permission,” she says, pouring thick iced coffee into plastic cups. “But no one here was angry. We all know the big boats have been coming closer. My son went out last week and caught only half a bucket of scad. That’s not enough to pay for ice.” Hoa’s earnings have dropped too, because fewer day-trippers stop for coffee when the road looks like a construction site. Still, she keeps a spare coil of rope under her bench, just in case the net needs repairs.
- Villagers use old nylon nets and bamboo to block roads leading to the sea.
- The practice began as a folk tactic and now appears in at least six provinces.
- Peak seasons for nets are squid runs and times when illegal trawlers are spotted.
- Tourism projects and fuel prices add pressure on already stressed near-shore stocks.
- Google Maps now marks some nets as local checkpoints, showing how common they are.
- Government officials order nets dismantled, but new ones appear within days.
- The underlying grievance is the feeling that the sea is being taken from small fishers.
Fifty kilometers south, Le Van Duc steers a steel-hulled trawler that fishes from Thanh Hoa to Da Nang. He considers the town nets a slap in the face. “We already carry red books that show where we’re allowed to fish,” he grumbles, referring to the government-issued logbooks. “If locals want to protect a reef, they should talk, not block a public road.” Duc admits that some captains cheat, but he insists most obey the rules. When his crew encounters a town net, they must anchor offshore and wait for the tide to shift, burning extra fuel. “One night we waited six hours. That’s 40 million dong lost,” he says. Duc has started posting photos of nets on a captains’ chat group, urging owners to avoid ports where nets appear. The boycott hurts fish traders, who now travel to inland towns looking for middlemen willing to brave the barriers.
A net across the road is cheaper than a patrol boat that never comes.
When the sea moves closer, the boats that follow it get closer to our villages.
Every honk at the net is a reminder that someone else wants what little we have left.
We build with old gear because the law forgot to guard the water.
Local officials walk a wobbly tightrope. Tran Minh Thang, vice-chairman of a coastal commune in Nghe An, says his office receives complaints almost weekly. “We understand both sides. The law says roads must stay open, but we also need to keep social harmony.” Last summer, Thang brokered a compromise: nets could stay from sunset to sunrise, but must be lowered during daylight. The deal lasted two weeks. On the fifteenth morning, a tourist bus scraped a bamboo pole and shattered a headlight. Photos hit Facebook, the provincial traffic police intervened, and the nets came down for good. Thang sighs, “We’re firefighters, not fishermen. We can’t solve resource conflict with traffic cones.”
- Town nets are homemade fishing-gear roadblocks that guard village fishing grounds.
- They spread as warming seas and big trawlers move fish closer to the beach.
- Authorities often remove them, yet copycat nets keep popping up along the coast.

The Spread and the Pushback
Copycat barriers now pop up faster than officials can map them. In Quang Ninh, where the border with China meets the sea, nets appear during the crab-molting season. In Ca Mau, at the southern tip, Khmer communities stretch netting across mangrove creeks to deter electric-shock poachers. Each place rewrites the rules: some nets are pink, some green. Some carry hand-painted signs that read “Local fishing only,” others are so low that motorcycles pass underneath while pickup trucks must turn around. The variety makes enforcement nearly impossible. A traffic officer in Ha Tinh laughs when asked if he carries wire cutters. “We’re told to issue warnings first, but what if the villagers resist? We’re outnumbered, and nobody wants a riot on Facebook.”
Yet pushback is growing. Hotel investors argue that nets hurt tourism branding. “You can’t sell a beach as pristine if guests must step over old fishing gear,” says Pham Hong Thai, who manages a resort south of Nha Trang. After a net appeared on the only road to his property, occupancy dropped 30 percent in a month. Thai responded by offering free boat rides for local children, funding a mangrove cleanup day, and paying the village fishing association a monthly stipend to keep the road clear. Critics call it quiet bribery. He calls it the price of peace.
Environmental groups worry about another unintended consequence: abandoned net fragments washing into the sea. Ghost gear already accounts for roughly 10 percent of marine plastic in Vietnamese waters. When town nets are hurriedly dismantled, small pieces slip loose, entangling turtles and seabirds. A project run by the International Union for Conservation of Nature now offers villages lightweight biodegradable jute panels as an alternative. The catch is cost. A jute panel runs four times the price of synthetic mesh, and donors can subsidize only a handful of villages each year.
FAQ
- What are town nets and why do villagers build them?
- Town nets are temporary roadblocks made from fishing gear like nylon mesh and bamboo. Villagers string them up to slow outsiders during peak fishing seasons and protect local waters they feel are being emptied by industrial trawlers and tourists.
- Where in Vietnam are town nets appearing?
- They now show up in at least six coastal provinces from Quang Ninh in the north to Kien Giang in the south, with notable clusters in Thanh Hoa, Ha Tinh and Nghe An where small fishers say big boats are encroaching.
- Are town nets legal?
- The government calls them a nuisance and traffic hazard. Some local authorities quietly allow them, but most nets are erected without permits and officials usually order them removed once photos go viral.
- How does climate change make town nets more common?
- Warmer surface water pushes fish closer to the cooler coast, drawing large trawlers inside the three-mile buffer meant for small boats. Empty baskets and fuel costs push villagers to block roads instead of chasing fish offshore.
- Do town nets actually protect fish stocks?
- They mainly buy time and publicity. Nets slow intruders for a few days, but without larger marine enforcement the same boats return; the real value is drawing attention to the squeeze between industrial fleets and coastal development.

Looking Ahead
For now, the nets keep multiplying, driven by a simple equation: fish grow scarce, patience grows thinner, and a roll of nylon costs less than a day in court. Government agencies have floated ideas such as color-coded fishing zones enforced by drones, or communal insurance funds that pay villagers when outsiders are caught cheating. None have moved past pilot stages. In the meantime, commuters learn to ask “Is the net up?” before setting out, the same way farmers once asked about the tide.
The deeper fix requires something sturdier than bamboo: transparent data on where boats fish, how much they take, and how fines are spent. Villagers need proof that rules work before they will trade their nets for paperwork. Captains need assurance that one unfair fine doesn’t wipe out a season. Until then, a traveler heading to any beach between Tra Co and Ha Tien should pack an extra ounce of patience, and maybe a small flashlight, in case the road ends at a wall of woven nylon and quiet determination.
