Estuarine Ecosystem Analysis

Improved Essays
An ecosystem is a natural system where living, or biotic, and nonliving, abiotic, factors function together in an environment. There are several types of ecosystems, but I will be explaining what an Estuary is, the biotic and abiotic factors that can be influenced by natural and human-caused disturbances, natural resources Estuaries provide and how as good stewards we can sustain or assist in this invaluable ecosystems recovery.
Estuaries are semi-closed bodies of water where freshwater meets with salt water in places such as inlets, bays, or flood river valleys. They help filter out sediment and pollution before going out to the ocean. In addition, they provide natural habitats for animals and sea creatures, as well as providing protection

In addition, the health or biogeochemical cycle of an estuary can be determined by abiotic and biotic factors. Abiotic factors include salinity, water depth, air and water temperature. Biotic factors include plants to provide base for food, shade or habitats, bacteria or decomposers which break down the dead to recycle matter back to soil and water, and competition of prey for food availability (NOAA, 2008) Because of this natural circulation of abiotic and biotic factors, nutrients are constantly recycled back into the environment to start the process all over …show more content…
The pounding of waves along a coastline can erode or destroy beaches, salt marshes, and other inland habitats, as well as dislodging or burying indigenous plants and animals with other sediment permanently damaging them. Human-caused disturbances include pollution from dumping chemicals, heavy metals and other wastes into the water causing the largest decrease in water quality (NOAA, 2007). Organisms must adapt to the abiotic changes such being to withstand the harsh environments whether caused by natural or human-caused disturbance. Shellfish, barnacles, or mussels latch on with strong appendages to surfaces, or ghost crabs bury themselves in the sand (MarineBio, 2016). The biotic changes are what species or organisms remain after a natural or human-caused disturbance; the species diversity such as fish, shellfish, and bird that can be measured. In addition, vegetation such as algae that produces chlorophyll E can determine how much algae is the water (NOAA, 2011). Unfortunately, whether it is a natural or human-caused disturbance, it can result in complete destruction and loss of an estuary habitat permanently disrupting abiotic and biotic

    Water intake structures are clogged increasing maintenance cost for water treatment plants ("CISR: Quagga & Zebra Mussels," 2011). Adversely affected through large accumulations are boat hulls, anchors, and beaches ("CISR: Quagga & Zebra Mussels," 2011). Native fresh water mussels can be destroyed by Zebra and quagga mussels ("CISR: Quagga & Zebra Mussels," 2011). Native shells can be destroyed from the mussels attaching to them ("CISR: Quagga & Zebra Mussels," 2011). Another process in which native mussels are destroyed is through the overabundance of shells which drastically reduces the amount of food availability for the native species ("CISR: Quagga & Zebra Mussels," 2011).…

    A nutrient management plan will be implemented for farmland that borders Lake Okeechobee since this lake is the main cause of algal blooms. [9] The following factors will be used to assess nutrient content on land and will be used to determine how much fertilizer can be used. Livestock population: monitoring livestock population can help estimate potential nutrient content Feed management: Animal feed has various nutrients that can pollute soil and water Farming practices: Farming practices can add unwanted nutrient pollution from the use of fertilizer and other chemicals. Animal and water waste handling: Animal waste contains nutrients such as phosphorus and nitrogen, which can pollute surrounding waters. Proper handling of waste can help alleviate nutrient concentration.…

    Application of Biofloc technology in aquaculture systems; a viewpoint Anjali P. Thilakan1*,Manju Lekshmi. N2.,Sreekanth.G.B2, N. P. Singh2 1Central Institute of Fisheries Education, Andheri (W), Mumbai 2ICAR Central Coastal Agricultural Research Institute, Ela, Old Goa . Abstract Bioflocs are aggregates (flocs) of algae, bacteria, proto¬zoans, and other kinds of particulate organic matter such as feces and uneaten feed and it normally contains 35-40% of protein. Biofloc technology ensures sustainable aquaculture and protecting fish from variety of disorders and infections. Microbial flocs developed under the biofloc technology function as potential food sources for fish.…

    This gives rise to rival clashes within the ecosystem damaged due to pollution already.  Land Runoff – when water infiltrates the soil to the maximum tolerance level & the excessive water from rain, flooding or melted ice flows into the ocean along with those impurities dissolved in them. It picks up the man – made, harmful contaminants polluting the ocean. These impurities are accounted for by the fertilizers, petroleum, pesticides and other soil contaminating chemicals. Dead zones are created by the inflow of fertilizers and wastes from land animals and humans too which are a huge detriment to the oceans.…

    It has resulted in the exploitation of fishes and crustacean in the area. The development of coastal structures over the years has resulted in drastic changes to the coastline which leads to the degradation of major ecosystems within the area. This region is a small bathing area and a docking area for yacht moorings that includes a Coast Guard facility and a restaurant/club located on the waterfront of the peninsula. Previous studies in the 1980s showed that the area was contaminated with sewage (IMA,unpublished, P.Norman,unpubl.). Its main source of pollution was due to broken sewage systems lines located underwater.…

    One of the top causes of pollution is industrial waste. Industries like to produce various types of pollutants that are extremely harmful to the health of people and the environment such as asbestos, lead, mercury, nitrates and sulfur. Many of these industrial facilities do not have a proper waste management system so they drain their waste into fresh clean water to carry away the waste from their facility and into other bodies of water causing a contamination in the water. These contaminations can be catastrophic to the creatures of the wildlife such as fishes and birds. This can cause the fishes to suffocate, prevent the birds from flying due to their feathers getting caught in the waste, and prevent sunlight from shining on the photosynthetic aquatic plants.…

    Increased ocean acidification isn’t the only thing affecting the ocean, but it is very problematic because it erodes aragonite which is a mineral of calcium carbonate. In other words it kills corals and causes the hard exoskeleton to erode. Action needs to be taken to ensure the survival of corals and the creatures that rely on coral reefs to survive. Coral reefs are sources of food for millions of people, but also are sources of medicines. As coral reefs disappear so do the organisms that are mutualistic to it.…

    Rising sea levels will increase the movement of salt water into fresh water ecosystems. It will also affect coastal erosion and sediment build-up which will have a negative effect on most of the fresh water organisms living in these fresh water ecosystems. The most unique characteristic of an estuary is the mixing of salt and fresh water. If rainfall and flooding patters were to change it would have a huge impact on estuarine and other coastal habitats. The fresh water flow for these habitats are determined by the size, timing and variability of rain events.…

    Climate Change is already having a profound effect on life in the marine ecosystem. It influences fisheries’ productivity through its effects on primary production, food web, interactions and distribution of species. This gave way for climate-related issues on fisheries and aquaculture for being identified. This paper develops a framework for the study of how climate change affects fish productivity and the possible impacts of low fish production on aquaculture and to us humans. So further research must be done to understand and prepare for the impacts that climate change will have on aquatic ecosystems.…
