Smelt
The smelt or European smelt (Osmerus eperlanus) is a species of fish in the family Osmeridae.
The smelt is a sea fish that lives in the coastal waters of Europe from the Baltic Sea to the Bay of Biscay. A freshwater form, known in Germany as the Binnenstint ("Inland smelt"), is common in the larger lakes of Northern Europe.
The smelt gather and swim about in the underflows of stronger currents in order to spawn above areas of sand. This takes place from the end of February to March, if the water temperature is above 9 °C (48 °F). The egg count per female can be as much as 40,000. After spawning there are often mass deaths. The smelt feeds mainly on small plankton crabs, ground animals and even its own young.
