Background
plankton, the organisms are suspended in water. Due to the physical nature and size Plankton can not make a motion to maintain the current. The only fly in the direction of the current. Most phytoplankton are small, can be seen with a microscope (Nantana NHA SingSinghaseni, 2554: 39) phytoplankton algae floating in the water can not photosynthesize. Have a vital role to humans, whether they are directly and indirectly. Phytoplankton species such as direct human food algae spirulina. Certain antibiotics such as algae Chlorella. Which contain chlorate Lynch. The use of antibiotics By way of phytoplankton is an important supplier in the water. There are environmentally sensitive And organisms in the water. By phytoplankton is a living link between the Primary Production (Primary Productivity) Fish and Shellfish. Phytoplankton is regarded as evidence in the food chain (Food chain) of natural sources (daughter hue with loyal settlement, aerosols and Mr. Wong, 2548),
a natural source of water. Are essential elements for the growth of phytoplankton. Buy enough to meet the needs of the creatures in the water. But today nutrients from sewage or waste water was discharged into the river. It is reported that the call Phil applications. (Eutrophication), resulting in a phytoplankton caused the growth and proliferation, called Plankton blooms or Algel bloom, which causes a color change that results in reduced oxygen at night, bacteria use oxygen to decompose made. creatures die due to lack of oxygen (daughter hue with loyal settlement, aerosols and Mr. Wong, 2548)
factors affecting the distribution of algae are many factors, such as seasonal temperature and amount of nutrients in the water. The rainy season may be leaching nutrients from the ground into the natural water hoard food for the phytoplankton. When appropriate temperature conditions will cause rapid reproduction. The study phytoplankton helps to know the biology of the water has more to say to the rich. Or productivity of water resources Can be an indicator of water quality, including an indication of the pollution of water sources. The phytoplankton species are resistant to different water quality, which can be used as an indicator of water quality. This research studied the diversity of phytoplankton in the river yet. The river is very important for the people of the province. The use of water for agriculture and fisheries, etc. 2. Objective 2.1. To investigate a variety of expensive plants spread in the province's 2.2. To study the physical and chemical water quality of some of the water which can affect the amount and type of phytoplankton 2.3. The data in the study to compare the distribution of phytoplankton and quality of water resources 2.4. The data will be used as an indicator of the water quality of the river, yet the province.
