Oh My Cod!
Many species in the Baltic Sea interact and are dependant upon one another. Cod eats sprat and herring while sprat and herring feed on cod eggs and even small cods. This creates an interesting dynamic as large sprat and herring population mean more food for cod, but at the same time larger amounts of cod eggs and larvae eaten by sprat and herring. It is an iconic species that plays a key role in the Baltic Sea ecosystem, both environmentally and commercially. It is also an important and valuable fish, it has been supporting the livelihoods of coastal communities for centuries.
Baltic Sea is a rather shallow sea filled with “brackish” water (a mixture of saline and freshwater coming from open ocean and surrounding rivers). The environmental conditions of the Baltic Sea change drastically along its length, the southwestern part is warmer and more saline while the water in northern parts is colder and almost freshwater.
