seitä

Seitä refers to the fish species belonging to the genus Pollachius, commonly known as pollock in North America. These are marine fish found in the North Atlantic Ocean. There are typically two recognized species: the Atlantic pollock (Pollachius pollachius) and the coalfish (Pollachius virens), though the term "seithe" can sometimes be used more broadly or interchangeably depending on regional dialect and culinary context.

Atlantic pollock are characterized by a green-tinged body and a prominent lower jaw that protrudes. Coalfish, on the other hand, are generally darker, often with a greenish or blackish hue, and have a more pronounced lateral line. Both species are demersal, meaning they live near the seabed, and are found in cool to cold waters. They are commercially important food fish, valued for their white, flaky flesh.

In European culinary traditions, particularly in Germany and Scandinavia, "Sei" or "Seelachs" (meaning sea salmon) is a popular name for coalfish. It is often smoked, fried, or used in fishcakes and various fish dishes. The taste is considered mild and slightly sweet, making it versatile in cooking. It is also a source of protein and various nutrients.
