Types of Lakes and Ponds
Fish in general have a range of physiological tolerances that are dependent upon which species they belong to. They have different lethal temperatures, dissolved oxygen requirements, and spawning needs that are based on their activity levels and behaviors. See your local hatcheries for suggestions on stocking and requirements.There are three basic types of lakes - Eutrophic lakes, which are primarily nutrient rich water bodies with large inhabitant life such as birds, reptiles, microbes, mammals and plankton. These lakes normally have a depth ranging from roughly 1 foot to several feet and nuisance plant infestation varies greatly depending on the surrounding and inherent conditions. Oligotrophic lakes are limited in nutrients and are generally more asthetically pleasing to the eye due to the lack of foliage and undergrowth while dystrophic water bodies, also low in nutrient qualities, display a murky brownish tone due to free floating soil and clay particles found in abundance Lakes are generally segregated into categories including the shoreline known as the litoral, the bottom sludge layer known as the profundal and the water base known as the pelagial. Surrounding most lake and pond shorelines lives aquatic plantlife from scare to abundant quantities ranging from microscopic algae to larger ferns, all of various species with diverse requirements. Common lake fish include silvers, trout, carp, catfish and bass which find the habitat a perfect setting for sustenance and reproduction. Floating wood, grasses, leaves and insect pools are often found on the shoreline along with minerals, rocks and soils. The sludge layer of a lake or pond is normally a compost of decaying matter such as insects, feces, plants, leaves, fish, foul and mammals. The sludge layer, when overburdening the waterway, is often a main fuel for algae and nuisance plant life and in ornamental water ways requires a treatment of bacterial digestants to degrade and breakdown the ever accumulating slime and sludge.
Whether for recreation or habitation, lakes and ponds offer an immensely diverse ecosystem with broad and substantial character differences all attracting and sustaining various life from single cell anemia to people of all countries.
