The suffix trophic refers to growth, thus a eutrophic lake has a high concentration of nutrients and plentiful plant and algae growth and is the opposite of an oligotrophic lake. Eutrophic lakes, on the other hand, are productive: net primary production…. Oligotrophic sites are more variable than dystrophic standing waters. Water bodies are found all over the world. Lake George, New York, an oligotrophic lake The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. Examples of lake system types are oligotrophic, eutrophic and mesotrophic lakes. This lakes or water bodies support aquaticspecies that require well-oxygenated, cold waters such as lake trout, char andwhitefish. These bodies tend to differ in terms of nutritional content, geographical location, and pollution rates. Tend to be quite clear water body in Northern Minnesota, Quite common in cold regions in the world, Has low content of phosphates and nitrates, The ecosystem is dominated by green algae, Examples of oligotrophic lake species are whitefish and trout, Lakes are formed through eutrophication process, Have a high density of algae, vascular aquatic plants, and phytoplankton, Tend to be quite fertile due to the high level of nutrients, The color of the water is dark due to the blue-green growth of algae, Have low species diversity but the high population density, Dominated by green algae in the ecosystem, Eutrophic lake species are pinfish, largemouth bass, and perch, Eutrophic lakes are shallow in depth while oligotrophic lakes are deep in-depth, Oligotrophic lakes have low phosphate and nitrates while eutrophic lakes have a high level of phosphate and nitrates making them fertile, Eutrophic lakes have high primary productivity while oligotrophic have low primary productivity, The oligotrophic lake is rich in oxygen amount while the eutrophic lake has low oxygen amount, The oligotrophic lake has high species diversity of green algae while the eutrophic lake has a high diversity of blue-green algae species, Oligotrophic lake ecosystem is dominated by green algae while eutrophic lake ecosystem is dominated by blue-green algae, The oligotrophic lake has low trophic index while the eutrophic lake has a high trophic index, The chlorophyll content in the oligotrophic lake is low while high in a eutrophic lake, The oligotrophic lake has a low density of species while eutrophic has a high density of species, The oligotrophic lake has clear water for drinking while the eutrophic lake has dark water, Algae bloom is rare in the oligotrophic lake while frequent in a eutrophic lake, Oligotrophic lake occur in colder regions while eutrophic lake in warmer regions, The oligotrophic lake has a low chance of eutrophication process while the eutrophic lake has a high chance, The oligotrophic lake is not an indicator of pollution while the eutrophic lake is a direct indicator of pollution, The oligotrophic lake has low dissolved oxygen while the eutrophic lake has a high level of dissolved oxygen, Eutrophic lake species examples are largemouth bass, perch, and pinfish while oligotrophic lake species examples are whitefish and trout, Both contain biotic and abiotic components. mesotrophic lake . The sampling were done in two manmade lakes, Faculty of engineering (UPM) (3.005885 latitude, 101.720271 longitude) as oligotrophic lake, and Seri Serdang (3.004689 latitude, 101.714071 longitude) as mesotrophic lake (Fig. Analysis of ice samples showed ecologically separated microenvironments.
