It prefers nutrient-rich waters such as those found in eutrophic water or those polluted by waste water.
2.
Many live in eutrophic waters of generally poor quality and feed on tubifex worms and similar benthos associated with such habitat.
3.
This eutrophic water ultimately leads to no dissolved oxygen remaining within the ecosystem because of increased activities of algae and decomposers.
4.
The loss of larger plants and reed fringes in eutrophic waters increases erosion of banks and the buildup of sediment on lake floors.
5.
However, in a eutrophic water condition, a plankton net with a mesh larger than 100 ?m should be chosen to avoid clogging the net.
6.
Their ability to regulate buoyancy is key to their dominance of eutrophic waters, by optimally positioning themselves within the photic zone in a stable water column.
7.
Intensive farming of fish in ponds spread using one type of carp who thrived in eutrophic water conditions and who feeds on algae, causing widespread pollution.
8.
Members of genera " Saccostrea " and " Crassostrea " generally live in the intertidal zone, broadcast sperm and eggs into the sea, and can thrive in eutrophic water.
9.
The research programme will address three key areas of water resource management : reservoir management, treatment of eutrophic water and enhanced clarification focusing specifically on the Sungai Johor plant.
10.
Wetland habitats are also present, with springs, an old reservoir near Collennan and a very eutrophic water body, Merklands Loch, all contributing to the high biodiversity of the site.
