During the last weeks, different localities have reported serious episodes of mortality de peces Both on beaches and in rivers and lagoons, generating concern among residents, researchers, and environmental authorities. The lack of official information and uncertainty about the specific causes increase public concern about possible damage to the ecosystem and public health.
Testimonies and photographs sent by citizens and users on social networks, especially from tourist areas such as Biojagua Beach in Bávaro, have highlighted the extent of this phenomenon, which to date has not received a definitive explanation from the authorities responsible for the environment.
Main causes behind mortality de peces
Experts consulted point out that the mass death de peces can be caused by multiple reasons. Among the most frequent are: sudden changes in water salinity, extreme drops in temperature, lack of oxygen, the presence of diseases, as well as pollution resulting from the dumping of industrial waste or the impact of power generators on the marine environment.
Recently, a research group at the National University of RÃo Cuarto In Argentina, numerous mortality events were detected de peces after a cold snap. According to their studies, factors such as depth of the body of water, the type of environment (river, stream, lagoon, reservoir) and limnological conditions directly influence the magnitude of the damage.
In the province of CordobaSome streams even froze from bank to bank, causing the death of a large number of specimens, as occurred in the Colón stream at the beginning of July, demonstrating the vulnerability of some species to low temperatures.
The influence of the environment and the role of pollution
In the region of Bávaro, Dominican Republic, Marine mortality has also been linked to pollution generated by electric barge operations. In addition, the massive presence of sargassum This requires the deployment of equipment and machinery to remove this macroalgae from the beaches, sometimes altering the natural balance and affecting water quality.
Meanwhile, in the Pirapó River of Paraguay, residents and fishermen have reported mortality de peces. The Ministry of Environment and Sustainable Development intervened, following citizen complaints, to carry out sampling and measurements of the water in the affected areas. Although no dead fish were observed at the locations inspected during recent visits, samples have been sent for thorough analysis to clarify the causes of the phenomenon and ensure the protection of water resources.
Impact on the environment and society
The mortality de peces not only represents a threat to aquatic biodiversity, but also affects the local economy, especially in areas where fishing and tourism depend heavily on the health of these ecosystems. Uncertainty regarding the causative factors makes it difficult to implement effective preventive and corrective measures.
Civil organizations and communities have been carrying out removal work de peces and beach clean-ups, while they await an official response and long-term solutions. It is essential to environmental monitoring and cooperation between government agencies, universities and society to identify risks in time and prevent these events from happening more frequently.
The increasing incidence of mortality de peces In various regions, it continues to raise alarm among experts and environmental authorities. Community participation in observation, reporting, and supporting investigations is crucial to addressing this ecological challenge and protecting aquatic resources and the quality of life of riverside communities.
