hypereutrophic

Lake densities are generally lower here than in the Northern Lakes and Forests, and lake trophic states tend to be higher, with higher percentages in eutrophic and hypereutrophic classes.

Comparative studies based on lakes covering a wide range of geographic areas and trophic status have suggested that fish production in oligotrophic to hypereutrophic lakes of moderate depth is better correlated with primary production than the morphoedaphic index [7].

The southern lakes, such as Apopka, Carlton, Beauclair, Dora, Harris, Eustis, Yale and Griffin, often receive mineralized groundwater as well as surface inflows through nutrient-rich soils, and are eutrophic to hypereutrophic hardwater lakes.

The nutrient enrichment can cause important ecological effects on aquatic communities (Table 3), since the overproduction of organic matter and its subsequent decomposition usually lead to low dissolved oxygen concentrations in bottom waters and sediments of eutrophic and hypereutrophic aquatic ecosystems with low water turnover rates.

Extensive kills of both invertebrates and fishes (sensitive benthic species, particularly) are probably the most dramatic manifestation of hypoxia (or anoxia) in eutrophic and hypereutrophic aquatic ecosystems, with significant reductions in the area of suitable habitat for food, growth and reproduction.

Turbid water from hypereutrophic waters contaminated with animal manure have caused excessive bacterial growth on skin of Channel Catfish from Upper Great Miami River watershed in Mercer County.
