The Tywi River in Carmarthenshire, Wales, has experienced a dramatic decline in fish populations that threatens the continuation of coracle fishing, a practice dating back centuries in the region. Testing conducted by the Save the River Tywi campaign group identified multiple sources of pollution including industrial discharge, agricultural runoff, and human waste. Fishermen reported observing dead fish in the water and described conditions as severely compromised.
Currently, only four coracle fishing licenses were issued for the 2026 season compared with twelve when association chairman Andrew Davies began fishing 38 years ago. Davies stated that the four active fishermen collectively caught approximately twelve fish for the entire season between May and July, whereas previously they would catch that quantity in a single night. One fifth-generation fisherman reported catching only one fish during the three-month period. The economic impact has been substantial, with many traditional fishermen losing enthusiasm for the profession.
Multiple entities have been identified as potential pollution sources. Welsh Water acknowledged its responsibility and announced plans to invest £889 million in storm overflow improvements from 2025 through 2030, including six projects specifically targeting the Tywi. Electronics recycling company Mekatek, which operates under a discharge license from Natural Resources Wales, disputed claims it contributed significantly to pollution. Local residents have circulated videos allegedly showing discharge from industrial operations.
Natural Resources Wales stated it maintains ongoing enforcement and compliance investigations within the Tywi catchment, with some cases proceeding toward court proceedings. The Welsh government attributed some recent environmental concerns to natural conditions while acknowledging awareness of foam, odors, and discoloration issues. Local officials and lawmakers called for stronger action against polluters, emphasizing shared responsibility across water companies, agricultural operations, and residents. The annual Tywi River Festival was cancelled in July due to pollution concerns.
