In the present study on flounder from five locations in the German Bight, parasites from 30 different taxa were identified, including 24 macroparasite and 6 microparasite taxa. Researchers have used strip-spawning to produce fertilized eggs for larvae culture. As a small flatfish that inhabits estuaries, bays, and the coastal zone, this species is vulnerable to shifting environmental conditions in many of the habitats critical to its life cycle.
