Definition
The European smelt (Osmerus eperlanus) is a small, slender fish native to Europe's coastal waters and rivers. They are known for their distinct cucumber-like odor and silvery appearance. European smelts are anadromous, migrating from saltwater to freshwater to spawn. Think of them as the 'original' smelts, representing a key species in European ecosystems. They are an important food source for larger fish and birds. These fish are often caught and consumed locally. Their presence indicates the health of the aquatic environment.
