Nongprue Municipality Acts to Curb Overpopulation of Fish in Suan Pho Pond

Nong Prue, August 13th, 2026

Nong Prue Municipality is taking urgent action to address a severe overpopulation of fish in the pond at Suan Pho (also known as the public park commemorating His Royal Majesty the King’s 82nd birthday), after various species proliferated so densely that the water became oxygen-depleted, other aquatic animals began dying, and the pond developed a foul odor affecting the surrounding environment.

Today, Mayor Winai Inthaphithak, together with municipal executives, directed officers from the Disaster Prevention and Mitigation Division, working alongside Civil Defense Volunteers (Or Por Por), to the site. The team has begun catching fish and managing aquatic life in the pond to restore balance.

Officials discovered that multiple fish species had multiplied rapidly, overcrowding the water body and disrupting the local ecosystem. Low dissolved oxygen levels left some aquatic animals unable to survive, with deaths already observed in the pond.

The operation prioritizes fast-breeding and highly adaptable species such as walking catfish and Nile tilapia. These fish thrive and reproduce quickly under varied conditions; when their numbers become excessive, they can upset the ecological balance of the water source.

Caught fish are carefully sorted, placed in tanks, and transported for release into suitable public water bodies, including Chak Nok Reservoir and Mapprachan Reservoir. This approach reduces the population density in Suan Pho Pond, eases pressure on its ecosystem, and gives the fish a better environment.

Larger aquatic animals found in the pond, such as iridescent sharks (pla sawai) and turtles, are being retained and returned to the water where appropriate. These species contribute to the overall character of the park and help maintain the pond’s visual appeal for the many residents who use the public space for recreation.

The effort forms part of the municipality’s broader commitment to environmental care and sustainable management of water resources in public parks. Officials want to prevent excessive aquatic populations from degrading water quality or harming other species. Catching and sorting will continue steadily, with suitable fish transferred promptly to the designated reservoirs to minimize stress during transport.

Beyond immediately relieving overcrowding, the measures are expected to improve water quality, restore longer-term ecological balance, and preserve the clean, attractive landscape of Suan Pho for the public to enjoy.
