"Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use ". fEutrophication Farms use fertilizer to make the soil fertile Some fertilizer can run-off into waters fEutrophication Excessive nutrients from fertilizers can cause eutrophication. The main effects caused by eutrophication can be summarized as follows [3]: 1. When they die, decomposers use the oxygen in the water for the process. During the Eutrophication, nutrients are released from runoff into water. Primarily, the adverse effects of eutrophication on aquatic bodies include a decrease in biodiversity, increase in toxicity of the water body, and change in species dominance. 4. For example, large macrophyte beds may form in response to nutrient enrichment and may cause higher water levels and reduced flows (in open systems). When these nutrients gather and grow, it results in an overgrowth of plants and algae. Combined effects of eutrophication and warming on polyunsaturated fatty acids in complex phytoplankton communities: A mesocosm experiment. Eutrophication from the over-enrichment of nutrients is among the serious threats to aquatic ecosystems around the world, causing various negative ecological impacts (i.e., algal bloom and fish kills; Hupfer and Hilt 2008; Smith and Schindler 2009).The rate and extent of the eutrophication process have been accelerated markedly by the increase in anthropogenic stressors, such as the soaring . A discussion of major EFFECTS OF EUTROPHICATION ON FISHERIES RESOURCES Eutrophication of a waterbody can have a number of effects on the quantity and quality of fish within the waterbody. Species diversity decreases and the dominant biota changes. Eutrophication has been shown to weaken diversity-stability relationships in grasslands, but it is unclear whether the effect depends on scale. This is one of the first definitions given . Several tens of plant species may occur, together with a rich fauna of, among others, insect larvae and amphibians. This can lead to algal blooms3. Phytoplankton have an important presence in ponds as primary producers. Natural eutrophication is a very slow process and watercourses and bodies of water change very gradually, thus maintaining habitat for various species for long periods. Introduction Eutrophication, climate change induced temperature increase, and microplastic contamination are among the biggest challenges that aquatic organisms face today. This has a number of dominance. It has an effect on species composition and can influence which species might have competitive advantages over others to become dominant [4]. Background information: "Eutrophication" also known as "hypertrophication" is the process in which the mineral and nutrient concentration in a water body such as lakes, ponds, reservoirs and etc increases which causes excessive growth of algae, plants, and phytoplankton in the water body. In other cases eutrophication may lead to increases in plant growth and increased plant biomass and resultant detritus after turnover. fEutrophication Eutrophication can cause algal blooms Algae consumes all the oxygen and sunlight What will happen to other aquatic Causes of Eutrophication. In shallow lakes with. This leads to suffocation of fish and other aquatic life. eutrophication, the gradual increase in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem such as a lake. Yearly mowing Many ditches are strongly affected by eutrophication usually hampers a further natural succession to helophyte due to agricultural nutrient losses. These nutrients can come from a wide array of . Meaning of Eutrophication: Inorganic nitrates and phosphates in excess amount stimulate excessive plant growth in lake and reservoir. II. Volume 843, 15 October 2022, 157001. eutrophication modeling approach in conjunction with fisheries resources management is discussed in a subsequent section of this paper. distance-based linear modeling 1. The plant deplete the oxygen content of water during night. The main environmental effects of eutrophication are increase of suspended particles owing to extensive macroalgal blooms, decrease of water clarity, and increase in the rate of precipitation that led to the destruction of benthic habitat by shading of submerged vegetation. However, few studies have examined the effects of eutrophication on the overwintering of exotic plants. III. eutrophication. The main environmental effects of eutrophication are increase of suspended particles owing to extensive macroalgal blooms, decrease of water clarity, and increase in the rate of precipitation that led to the destruction of benthic habitat by shading of submerged vegetation. These phytoplankton species are toxic and are inedible. Eutrophication is considered a water pollution problem that affects about 30-40% of all the water bodies in the world. The productivity or fertility of such an ecosystem naturally increases as the amount of organic material that can be broken down into nutrients increases. 2. Rate of sedimentation increases, shortening the lifespan of the lake. Effects of Eutrophication 1. 3. ; Productivity changes also affect the physico . Eutrophication often increases the frequency, intensity and duration of cyanobacterial blooms . With the intensification of global change, water level fluctuation (e.g., floods and droughts) will become more intense and frequent, and eutrophication will also be more severe and widespread in freshwater ecosystems ( Arnell and Reynard . Some of the consequences of eutrophication include destruction of aquatic systems and reduction in water quality. The following are some of the effects of eutrophication; 1. In View via Publisher Save to Library Create Alert 47 Citations Analysing a globally distributed network of . Eutrophication happens when there is an oversupply of nutrients in a body of water. In an aquatic ecosystem, eutrophication increases primary output and affects the relative abundance, taxonomic makeup, and spatial distribution of primary producers. This material enters the ecosystem primarily by runoff from land that carries debris . In addition to water pollution, there are several other effects of eutrophication on the ecosystem as well as the lives of various living beings. From a systemic point of view, it increases the primary production (photosynthesis), increases the biomass but diminishes the diversity and the composition, structure and dynamics of the affected ecosystems are altered drastically. Abundance of Unwanted Substances Eutrophication causes an abundance of particulate substances such as phytoplankton, zooplankton, bacteria, fungi and debris on which the turbidity and coloration of the water depend. Eutrophication or nutrient enrichment affects the entire aquatic system by altering trophic structure, biodiversity and biogeochemical cycles, as well as seasonal dynamics. Human activities - discharge of waste water, deforestation, wetland drainage, development of arable land and fertilization have accelerated the eutrophication process several times. The animals and fishes will die due to lack of oxygen levels. ; The distribution and movement of energy and biomass throughout the food web are affected by changes in resource mix and location. The direct consequence is an excess of oxygen consumption near the bottom of the water body. Turbidity increases. Effects of Eutrophication Change in Ecosystem. It is found in ponds, small lakes, and estuaries mostly due to the lack of a fresh-water outlet/inlet. Eutrophication and Water Chemistry Water chemistry is of great importance to freshwater systems such as ponds. As per Wikipedia, " Eutrophication or more precisely hypertrophication, is the ecosystem's response to the addition of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system. . The main cause of eutrophication1is the large input of nutrients to a water body and the main effect is the imbalance in the food web that results in high levels of phytoplankton2biomass in stratified water bodies. View PDF; Download Full Issue; Science of The Total Environment. Some other important effects of this process are listed below. Plant and animal biomass increase. Finally, the successful reversal of eutrophic conditions hinges on (1) effective problem identification, (2) cognisance of system-specific attributes, (3) formulation of innovative policies to. With the excess amount of nutrients, algaes and other aquatic plants growth increase. Effects of eutrophication The effects of eutrophication occur normally locally and regionally. Phytoplanktons grow much faster in such situations.
