The organic matter content of wastewater is expressed as chemical oxygen demand and biological oxygen demand. The dissolved oxygen content of water is important for survival of aquatic life. The disposal of high organic waste into rivers, lakes and seashore affects the fishes, other aquatic animals and plants. The dissolved oxygen content of water is measure of the water quality. Various factors affecting dissolve oxygen of water includes temperature, the respiration rate of aquatic life, the contaminants in water and water flow. Various investigators have carried out research to study factors affecting dissolved oxygen and effect of dissolved oxygen variation on aquatic life. The present review summarizes research carried out on dissolved oxygen and its effect on aquatic life and also factors affecting dissolved oxygen content of water.

Key words: Organic matter, chemical oxygen demand, temperature, aquarium, ecosystem.
