China’s Military Control Is Turning Fishing Grounds into Missile Zones

The sea appears calm from the pier at Pingtan, the windswept island opposite Taiwan. Nets are suspended to dry. A fisherman narrows his eyes at the horizon, where the grey band of the Taiwan Strait dissolves into haze. Then a muted explosion reverberates across the water, soft enough to be felt in the chest. It is a Chinese missile test, somewhere in the waters where he once set his lines.

The fisherman shrugs, yet keeps his gaze fixed on the waves. The fish have moved on, he says, or perhaps they have simply disappeared. The water feels altered now, he adds, as though it belongs to somebody else.

He gives a brief, joyless laugh and gestures towards the sea.

“That’s a drill zone now,” he says. “Not a fishing ground.”

The wind strengthens. The sky remains still. The sea does not.

When the frontline moves underwater

Across the disputed waters of the South China Sea and around Taiwan, the frontline is no longer defined only by warships and fighter aircraft. It now cuts through coral reefs, seagrass beds and historic fishing grounds that have supported families for generations. Beijing’s drive for military dominance has gradually recast these living environments as testing ranges, exclusion areas and strategic “grey areas”, consuming both livelihoods and wildlife.

Waters once surveyed for currents and fish movements are now plotted for missile paths and radar reach. The change is heard less in news reports than in the absence of the spluttering, chattering engines of small wooden fishing boats.

The sea has not gone anywhere, but people’s connection to it is changing rapidly.

Consider August 2022, when China responded to US House Speaker Nancy Pelosi’s trip to Taiwan by conducting live-fire exercises around the island. Officials designated enormous stretches of water as prohibited areas, including valuable fishing grounds. Taiwanese fishing boats were instructed to remain in harbour. Those who ventured near the exclusion-zone boundaries returned with sparse catches and accounts of patrol vessels and warning messages.

Satellite information from organisations including Global Fishing Watch showed fishing activity falling sharply during and after the exercises. Formally, the drills ran for only a few days. In practice, fear and disruption persisted on the water for weeks.

And that was only one episode that drew global attention.

Scientists and defence analysts are beginning to assemble a picture of what relentless militarisation does to the marine environment. Missile launches, sonar bursts, underwater drones and vessel movements all have an impact. Noise pollution can confuse dolphins and whales. Recurrent detonations may harm reefs and seabeds that serve as nurseries for innumerable species. Broad exclusion zones force fishing vessels into other waters where ecosystems are already under pressure.

Behind the sweeping language of “controlling strategic chokepoints” is a more basic truth: marine creatures do not recognise Exclusive Economic Zones or nine-dash lines. They respond only to stress, heat and noise.

Once those responses become lasting, recovery is not straightforward.

How security drills slowly erase living seas

One of Beijing’s most influential maritime instruments does not initially appear lethal: temporary “navigation warnings”. These official notices close areas for military operations, rocket launches or missile tests. On charts, they appear as tidy outlines. At sea, they slice across feeding areas, migration routes and coral shelves.

During the past decade, these warnings and “exercise zones” have expanded across crucial parts of the South and East China Seas. Some are limited and short-lived. Others are immense, closing areas of ocean larger than certain countries. From a satellite, this may look like no more than a shift in colour. For a crab fisher whose traps suddenly lie inside a missile corridor, it is devastating.

The trend is understated but unmistakable: drills are becoming more frequent, extending to more locations and lasting longer.

For many years, Chinese rockets launched from inland provinces such as Sichuan and Gansu have deposited spent stages in the sea. Trajectory maps indicate debris landing in waters off Taiwan, the Philippines and far into the South China Sea. Every launch brings a danger period, when fishers are advised to avoid particular coordinates where possible.

But many crews on small boats cannot afford to simply wait. They still head out, steering around exclusion areas marked on crumpled printouts or flagged by SMS alerts, hoping that the water remains calm. There are reports of vessels struck by debris, or crews discovering toxic-looking wreckage floating near their lines. Such incidents rarely reach the headlines.

For these crews, it is another hazard added to higher fuel costs, dwindling fish stocks and changing weather.

Marine biologists describe the accumulated effect of repeated drills as a slow-moving industrial accident. Explosions can briefly create shock “dead zones”, killing nearby fish and invertebrates. Heavy metals and propellant remnants may seep into the water column and sediment. Regular naval operations disturb seabeds, while sonar and radar trials introduce continual noise into an environment dependent on sound.

In truth, nobody counts the stunned fish following a missile splashdown. The official account centres on deterrence, readiness and power. What goes unrecorded is the octopus leaving its shelter after a blast, or the dugong no longer feeding where patrol ships now pass each day.

By the time lower catches appear in the data, the harm has often already become normal.

Living with a sea that doubles as a battlefield

Speaking with fishers from Hainan and Luzon to Taiwan’s eastern coast reveals a recurring survival method: they learn military patterns as carefully as they learn the tides. Crews exchange quiet intelligence about suspected exercises, ship activity and fresh “do not enter” boxes that materialise overnight in navigation apps. A captain in Kaohsiung called it “fishing in the gaps” – brief intervals between exercises or narrow passages beyond declared danger areas.

A crew may therefore depart at 2 a.m., speed through a slim band of safe water, set its lines, then retrieve them sooner than planned in case another warning is issued during the day.

This is not strategy. It is pressured improvisation.

People inland often presume that coastal communities can adapt without end: target different species, travel further offshore or locate new grounds. The reality is far more severe. Smaller boats cannot safely pursue fish into deeper, more open waters, which are already crowded with larger commercial fleets and coastguard vessels. Fuel bills rise as catch volumes fall.

Whenever a prominent political visit or abrupt escalation occurs, reports of new exercises spread rapidly through dockside chat groups. We have all known the instant when plans suddenly become unstable and it is clear that control lies elsewhere. For these communities, that feeling returns every few weeks.

On charts, it appears to be strategy; on the docks, it feels like whiplash.

Alongside the fishers, another, quieter group is also struggling to keep pace: local scientists and conservation workers. Many choose their words carefully because of political sensitivities, but their field records tell an unvarnished story.

“Every drill leaves a fingerprint,” a marine ecologist in southern Taiwan told me, asking not to be named. “Sometimes it’s dead fish washing up. Sometimes it’s just a change in behavior. Species that used to be bold become shy. Areas that buzzed with life go oddly still.”

They attempt modest, practical responses:

• Moving monitoring stations away from persistent drill areas to preserve long-term data as far as possible.
• Partnering with fishers to record unusual occurrences, including mass strandings, sudden silences and oily surface films after launches.
• Quietly advocating seasonal “no-drill windows” to safeguard spawning and migration.
• Establishing informal “quiet corners” where researchers and local crews alike avoid noisy engines and heavy equipment.
• Converting complex military notices into clear, practical warnings that fishers can genuinely use at sea.

These efforts are small against an enormous machine, but they still matter.

The uncomfortable question beneath the waves

China’s effort to secure military control in disputed waters is often presented as a chess game between great powers, centred on missiles, war games and forceful diplomatic declarations. Beneath that board is another reality: a sea where life is attempting to continue beneath the unceasing rumble of strategic theatre. Fish have no interest in who fired a particular rocket. Turtles do not follow the flag flying over a new artificial island. They respond instead to noise, heat, toxins and the gradual disappearance of places where they once fed or bred.

There is something disturbing about seeing fishing grounds slowly become missile zones while damage to marine life accumulates in forms that are difficult to observe and even harder to quantify. Major choices are taken far from the coast, in imposing halls and secure rooms. Their effects arrive on beaches as fractured coral, empty nets and unfamiliar debris carrying warning labels in languages that many coastal villagers cannot read.

The question hanging over these waters is not solely who will control them in 20 years, but what will remain to control. It does not end at China’s coastline; it extends directly to the choices made by every country when it regards the ocean first as a proving ground and only secondly as a living world.

FAQ:

• Question 1 Is this only about China, or do other countries do the same at sea?
  Other militaries also conduct exercises and missile tests in the oceans, but the concentration and scale around the South China Sea and Taiwan are notable because they overlap with some of the world’s most heavily used fishing and shipping routes.

• Question 2 Are there hard numbers on how many fish or species are lost from these activities?
  The evidence is incomplete. Certain local studies indicate falling catches and reef damage near regularly used drill areas, but tying precise losses to individual exercises is challenging, making accountability more difficult still.

• Question 3 Do missile stages and rocket debris really pollute the sea that much?
  Spent stages may contain fuel residues and metals that leach into the water and sediments. A single launch will not destroy an entire region, but repeated impacts across the same broad areas build a cumulative toxic footprint.

• Question 4 Can coastal communities push back against militarisation of their waters?
  Open resistance carries risks, but fishers’ cooperatives, local authorities and scientists sometimes press for safer schedules, smaller zones or compensation, while documenting impacts so they are not removed from the record.

• Question 5 What could realistically change this trend in the near future?
  Confidence-building steps between rival states, legally enforced “no-drill seasons” for essential habitats and regional debris-management agreements would all be helpful, even if they cannot resolve the deeper geopolitical contest.
