At Songkhla Lake, Jampen still tends her Yo Yak lift nets as she has for nearly fifty years, but the massive wooden structures that once dotted the water like sentinels now number barely three dozen where two hundred once stood. The ancestral fishing technique—so gentle it relies on gravity to lower and raise nets—has defined generations of families along this Thai shoreline. Yet pollution and declining fish stocks have turned the practice from livelihood into heartbreak, threatening to sever a cultural tradition that has survived centuries.
The collapse matters beyond nostalgia. Songkhla Lake represents a way of life woven into the identity of coastal communities, where fishers earned four to five thousand baht daily when waters teemed with Luk Bre fish. Now those catches have vanished, and young people like Jampen's own child have migrated to Bangkok's promise of steady wages and concrete futures rather than face empty nets. When fish disappear, tourism disappears; when tourism disappears, income disappears. When income disappears, people leave—and an entire world of knowledge and tradition walks out the door.
But something is shifting. Villagers and researchers have partnered on a project called "Searching for Luk Bre," mapping not just the decline but the path forward. Today, thirty-five volunteer fishers work alongside the research team, building fish shelters that provide habitat and nursery grounds for juvenile fish and aquatic life. These structures represent an elegant fusion of traditional knowledge and modern conservation: GIS mapping now visualizes what local wisdom has long understood—that fish density has genuinely plummeted, the data rendered in numbers and diagrams that can compel government attention where stories alone cannot.
The project documents the fish's life cycle and migration patterns, studying traditional processing methods alongside the ancestral lift-net technique itself. These aren't academics imposing solutions from outside; they're recording and revitalizing practices that local communities developed and refined over generations. Jampen speaks of the satisfaction of the work—the way a well-built Yo Yak, constructed with meticulous care, practically lifts itself through sheer engineering. That knowledge, combined with contemporary science, creates something more powerful than either alone.
Yet the fishers understand their own limits. As Jampen notes plainly, these conservation efforts are small activities in the face of industrial pollution and complex ecological collapse. "These issues are beyond the capacity of local communities to manage alone," she says. The real test lies with government agencies—whether they will respond to GIS mapping and structured research by protecting and restoring the lake. Without clean water and returning fish populations, no amount of volunteer effort or cultural pride can sustain a tradition.
There is hunger in Jampen's vision of renewal. She speaks of wanting her child to return, so the family can be together, so the Yo Yak can be lifted again not as a museum practice but as a living trade. That reunion—of people to place, tradition to prosperity, labor to dignity—depends on whether those with power over Songkhla Lake decide to act. The research is mapping the way. Whether anyone chooses to follow it remains an open question.
