Mass Fish Deaths in Yanbolu Stream in Trabzon Arsin Cause Concern

The mass fish deaths that occurred in the Yanbolu Stream, located in the Arsin district of Trabzon, have caused great concern among the local people and environmentally conscious citizens. In the footage recorded by a citizen with a mobile phone camera, it is clearly seen that there are dozens of dead fish in the stream bed. After the footage in question spread rapidly on social media platforms, the issue became a local agenda and attracted the attention of the authorities. Although no official statement has been made regarding the issue so far, various discussions have emerged about the reasons behind the incident. Local residents demand that the situation be investigated urgently and the natural life in the stream be protected.

Following the incident, citizens started to question the main reasons underlying the fish deaths. Among the opinions put forward, the pollution caused by domestic or industrial wastewater discharged into the stream holds a significant place. In addition, it is evaluated that the extreme hot weather conditions prevailing in the summer months threaten the living spaces of fish by increasing the water temperature. Some citizens think that the water structures built on the stream reduce the water flow rate and this situation leads to oxygen deficiency. As much as all these speculations, it is expected that a scientific and legal process be initiated to reach a definitive cause.

Experts on the subject emphasize that such mass fish deaths are generally not due to a single cause, but occur as a result of multiple factors coming together. The increasing air temperatures brought by the summer season cause the stream water to evaporate and, consequently, the water level to drop dangerously. The decrease in water level paves the way for a drop in the amount of dissolved oxygen in the water, which can cause fish to suffocate. In addition to this, organic and chemical wastes mixing into the stream further degrade the water quality, creating a heavy pressure on the ecosystem. Experts state that in studies conducted on the Yanbolu Stream in past years, it was determined that during similar drought periods, fish became trapped in small puddles and died due to lack of oxygen.

General assessments made by the authorities reveal that these types of mass fish deaths seen in streams show a seasonal trend. According to statistics and past data, such deaths are most frequently recorded in the June-September period, which extends from the summer months to the beginning of autumn. During this process, the water level dropping to critical levels and the accompanying oxygen deficiency are listed as the biggest risk factors for aquatic life. Authorities state that detailed investigations are essential to determine the exact cause of similar incidents. In this context, it is of great importance that both water samples and samples taken from dead fish are analyzed in a laboratory environment.

Following this environmental incident, steps are expected to be taken to raise public awareness and renew the trust placed in the authorities. Citizens demand that the causes of the fish deaths in the Yanbolu Stream be investigated transparently in all aspects. Sharing the analysis results regarding water quality with the public is seen as a critical step in alleviating the concerns of the local people. In addition, in the event that elements potentially harming the stream are identified, it is requested that necessary sanctions and environmental protection measures be implemented without delay. It has been understood once again that local administrations, environmental institutions, and the public must act together for the sustainability of natural life and water resources.
