Environmental advocates and researchers have raised concerns about trout farming in the Gulf of Riga, emphasizing the delicate ecological status of the Baltic Sea. At a recent conference focused on the Baltic Sea, World Wildlife Fund's Baltic Sea and Freshwater Program Manager Magda Jentgen highlighted that the Baltic Sea, the youngest sea in the world, is already recognized as one of the most polluted due to its shallow depth and slow water exchange, which exacerbates its vulnerability. Activists and researchers are calling for scientific considerations to form the foundation for policy decisions regarding the use of the Baltic Sea, aiming to balance economic activities with marine conservation efforts.

The fisheries sector expresses the need to reconcile economic activities with the interest of preserving marine ecosystems. Researchers assert that effective protected marine areas are critical for maintaining fish populations and overall fishery health. Jentgen warned of the chemical pollution that affects the sea both from historic causes and runoff from its vast drainage basin, which supports over 85 million inhabitants.

As the debate continues, the emphasis remains on safeguarding the fragile marine environment while considering the pressures of commercial fishing and aquaculture. The call for a balanced and informed approach is crucial, as the Balkan nations rely heavily on the resources the Baltic Sea provides, highlighting the need for sustainable practices to ensure the long-term viability of marine ecosystems and their fisheries.
