Abstract

 In this research, we present the role of fish farming projects in the destruction and pollution of the environment along the small river in Koya district. The scope of our research is the villages along the small river in Koya district. Due to the continuous increase in fish prices and low labor requirements and high income compared to agriculture, as well as the study area borders with Kirkuk province, which is a favorable market for selling fish products, especially after destruction Fish ponds in the province, especially fish farming ponds in Daquq, by the Iraqi government due to the high need for water, the number of fish ponds in the study area is constantly increasing, which The number of ponds is 1923. The area of ​​land allocated for fish ponds is 3057 acres, which is divided into three districts (Ashti, Taq Taq, Segirdkan). Taq. These ponds contribute to pollution of small rivers with their waste, emptying their pond water and dead fish waste into small rivers, and also contribute to soil pollution by polluting the coastal land Small rivers, due to mixing of pond waste, food and medicines to treat fish diseases on the one hand and decrease in oxygen in the soil under and near the ponds. The ponds contribute to air pollution in the area by emitting bad smells and the accumulation of flies in the ponds, which is a source of many communicable diseases.

 Due to the presence of small rivers, the study area is an important agricultural area in the Kurdistan Region, but due to the increased demand for fish, the number of fish ponds is increasing daily, at the expense of agricultural land It affects agricultural production, which is currently affected in Taq Taq district and will increase in the future and will affect the other two districts.
