Over the years, fishers in Thung Noi, a local fishing community in Prachuap Khiri Khan province, Thailand, saw a significant decline in their catches. Fewer fish and other aquatic resources meant growing concerns about the health of the marine ecosystem and the ability of fishing households to sustain their livelihoods.
Recognizing that the future of their community depended on the recovery of their marine resources, the fishers took matters into their own hands. Through collective action and locally developed rules, they began implementing measures to protect marine life and restore the ecosystem.
One of the community’s initiatives is the establishment of “fish homes”–structures that provide habitats and shelter for marine species. The community also created nursery zones where juvenile aquatic animals can grow and develop with less disturbance. These conservation efforts are supported by community-agreed regulations. Fishers have established rules prohibiting the collection of certain young marine species and protecting designated “egg” zones, allowing marine life to reproduce and replenish naturally.
For the Thung Noi community, these rules are not simply restrictions on fishing. They are collective agreements developed to ensure that marine resources remain available for future generations.
The community has also taken steps to revive its shellfish resources, which had become scarce for nearly a decade. To allow shellfish populations to recover, fishers introduced stricter harvesting practices. Collection is done by hand and with sieves to prevent the harvesting of smaller shellfish before they reach maturity. Seasonal closures are also observed, giving shellfish time to grow and reproduce.
The community’s efforts are beginning to produce visible results. Fishers have observed a notable increase in shrimp populations, along with early signs of recovery among other aquatic species.
For Thung Noi, these improvements affirm the value of collective action and community-led resource management. By establishing and enforcing their own conservation measures, fishers are helping restore the marine ecosystem while protecting the natural resources on which their livelihoods depend.
