Fish kill in Bistrica: Fishermen removed almost 30 kilograms of fish from the water

In the early hours of August 17, 2026, residents near the river Bistrica noticed an unusual number of dead fish floating in the water. Local fishermen quickly responded, removing nearly 30 kilograms of deceased fish from the stream. The cause of death remains undetermined at this time. The incident has raised concerns among local authorities and environmental experts, who are now investigating potential factors behind the mass mortality. The affected area spans from the middle of the park to the channel originating from the Zagrada, extending towards the oil refinery GEA’s facility. According to Franc Valand, president of the Ribiska Družina Slovenska Bistrica, the dead fish were found along this stretch of the river. He noted that there was no sign of fish dying in higher parts of the stream. This observation suggests that the issue might be localized rather than widespread. Representatives from the National Laboratory for Health, Environment, and Food were called to the site. They collected samples for analysis to determine whether the deaths are linked to water quality issues. The laboratory will examine whether contamination, low oxygen levels, or high water temperatures could have contributed to the phenomenon. Valand expressed skepticism about common causes such as low water levels, lack of oxygen, or elevated temperatures, suggesting these factors would likely affect other sections of the river if they were responsible. Valand believes that unless the results of the analysis indicate otherwise, the cause of the fish deaths may remain unclear. Until the findings are available, he emphasized that it is too early to draw definitive conclusions. The situation has prompted increased monitoring of the river's conditions, with officials urging continued vigilance. Local communities and environmental groups have shown concern over the incident. Some residents have expressed worries about the health of the river ecosystem, while others have questioned the adequacy of current water management practices. There is a growing call for more frequent testing of the river’s water quality and greater transparency regarding the findings. Authorities are currently awaiting the results of the laboratory tests before making further statements. In the meantime, efforts continue to monitor the river and assess any changes in its condition. If the cause of the fish deaths is identified, appropriate measures will be taken to prevent future occurrences. For now, the focus remains on gathering data and ensuring public safety.
