The Baltic Sea is under significant stress with the reported lowest water level since 1886, with a notable decrease of about 60 centimeters compared to the average level. This drastic change affects not only the water level but also the salinity and oxygen concentration within the sea. Experts indicate that such low levels create a favorable condition for saline water influx from the North Sea, which is critical for the survival of many native fish species that depend on this water exchange for reproduction and health.

This phenomenon comes after a harsh winter during which much of the Baltic Sea experienced considerable ice coverage, impacting traditional fishing practices. Local fishermen, like Andris Cīrulis Zvejnieks from Bērzciems, express a mix of optimism and concern, suggesting that while the current conditions might benefit their fishing catch in the short term, long-term consequences could threaten the ecosystem balance, impacting both fish populations and regional fisheries.

The last significant influx of saline water from the North Sea happened over a decade ago, highlighting the urgency for monitoring changes in salinity and water levels within the Baltic Sea. The environmental implications are profound, with potential repercussions for biodiversity in the area, including fish species that may not survive prolonged periods of low oxygen levels. Scientists and local communities are encouraged to prepare for potential ecological shifts and impacts on their livelihoods, as the situation evolves further.
