1. Zander inhabit freshwater bodies, preferentially large rivers and eutrophic lakes. 2. This contrasts sharply with mesotrophic or eutrophic lakes from similar climates. 3. Duckweeds tend to be associated with fertile, even eutrophic conditions. 4. The periphyton roughly equals the production level in temperate eutrophic lakes. 5. Health problems can occur where eutrophic conditions interfere with drinking water treatment. 6. A : It means a lake has become " eutrophic ." 7. Unlike most fish species, cyprinids generally increase in abundance in eutrophic lakes. 8. In some eutrophic aquatic systems, biodilution can occur. 9. Estuaries tend to be naturally eutrophic because land runoff discharges nutrients into estuaries. 10. However, zander need plenty of oxygen and soon disappear from eutrophic areas.
