Abstract

The mosquito fish Gambusia affinis is a small stout-bellied fish. Gambusia affinis is native to freshwater water bodies with low salinity in the eastern and southeastern United States and the Gulf of Mexico. Mosquito fish are also now seen all over the world. The body composition of fish is very interesting. In the body of fish there are some main products are present viz, protein, water, fat, minerals and carbohydrates. A synthetic fertilizer is applied for soil or plant tissue. Compound NPK fertilizer is containing three major nutrients necessary for the healthy growth of plants. The agricultural industry relies heavily on the use of NPK fertilizers to meet the world’s food supply and ensure healthy harvests. Our results showed that the freshwater fish Gambusia affinis had the greatest reduction in glycogen content. These results concluded that different concentrations of NPK fertilizers applied to the Gambrusia affinis remain in the body and their toxic effect on glycogen levels. Glycogen is used as a precursor for energy in fish under stressful conditions. Depletion of glycogen levels suggests the use of glycogen to overcome fertilizer stress. Glycogen breakdown increases due to the increased need for energy to detoxify stressful conditions.
