Invasive Fish Removed from Shei-Pa National Park Ecological Pond, Over 100kg Cleared
The Shei-Pa National Park Headquarters successfully removed over 100kg of invasive fish from the Wenshui Visitor Center ecological pond. By employing scientific fishing methods and public participation, they cleared 7 species and over 835 fish to protect native species.

The Shei-Pa National Park Headquarters (SPNP) announced that the ecological pond at the Wenshui Visitor Center had been invaded by non-native fish species. The SPNP commissioned a research team and combined this with ecological activities, using scientific fishing methods to precisely "remove the pests," successfully eliminating 7 species, over 835 fish, with a total weight exceeding 100 kilograms.
The SPNP stated today that the ecological pond at the Wenshui Visitor Center is a quiet corner for visitors to stop and feel nature. The pond water is drawn from the nearby Chuanlong Canal. Originally, the pond was dominated by native fish, including the Taiwan shovel-jaw carp, Chinese loach, Candidia barbata, and Rhinogobius rubromaculatus. However, invasive species such as red-eared slider turtles and tilapia gradually appeared in the ecological pond.
From 2024 to 2025, the SPNP commissioned a team led by Professor Chiu Yu-wen of the Department of Biological Resources at National Chiayi University to conduct a survey. They found 16 species of aquatic animals from 7 families in the pond, half of which were invasive fish species, including the aggressive largemouth bass, tilapia, and the leopard pleco, accounting for over 55% of the total population, indicating that the pressure from invasive species has affected the survival competitiveness of native fish.
The SPNP said that to remove the invasive species from the ecological pond, the research team targeted the habits of different fish species, using lure fishing, cast nets, gill nets, long submerged cages, and shrimp cages. After 6 precise removal operations and 2 events allowing the public to participate in "pest removal," they successfully removed a total of 7 species from 5 families, over 835 fish, with a total weight of over 100 kilograms, effectively slowing down the trend of invasive species breeding and spreading in the pond.
SPNP Director Lin Wen-ho stated that a healthy habitat is the core of ecological conservation. By mastering the current status of invasive fish in the Wenshui area through surveys and establishing management mechanisms, while promoting ecological education activities that encourage public participation, they aim to strengthen the environmental concept of "no releasing, no abandoning" and improve correct awareness of invasive species issues.
