The Ebro Delta: A Unique Ecosystem
Geographical and Environmental Importance
The Ebro Delta is formed by the mouth of the Ebro River as it flows into the Mediterranean Sea. Spanning more than 320 square kilometers, it is one of the most important wetlands in Europe and provides a diverse habitat for hundreds of species of birds, fish, and shellfish. The balance of salt and fresh water creates an ideal environment for aquaculture, particularly the cultivation of oysters and mussels.
Why the Delta is Perfect for Oysters
The mix of nutrients from the river and the Mediterranean’s salinity levels creates optimal conditions for oyster farming. The oysters feed on natural plankton present in these waters, resulting in a distinctive, clean, and slightly sweet flavor. The environmental quality and constant water flow make the Ebro Delta one of the most sustainable and productive areas for shellfish farming in Spain.
