Background & Aims of the Study: Environmental impact assessment is the identification
and systematic evaluation of the consequences of projects and programs on physical-chemical,
biological, cultural, and socio-economic components of the environment. Changes caused by
urban and rural effluents in the environment can directly affect the downstream part of the river.
The goal of this study was to evaluate the environmental effects of the fish farming center of
Miandoab and analyze the implementation and not implementation of the project at the two phases
of construction and operation, which was conducted using the Saratoga Matrix. In addition to
this goal, the physicochemical parameters of water and dissolved oxygen, Biochemical Oxygen
Demand (BOD), nitrate, phosphate, alkalinity, ammonia, temperature, and Chemical Oxygen
Demand (COD) were measured every 30 days in summer 2020.
Materials and Methods: Miandoab Fish Breeding Center on a land area of 2000 hectares
is designed for breeding hydrothermal fish. The Saratoga matrix was used to evaluate the
environmental effects and analyze the two options of implementation and non-implementation of
the project in the two phases of construction and operation. In the present study, four stations were
determined to investigate the effect of the Miandoab Fish Breeding Center on physicochemical
parameters of water in different parts of the Siminehrood river in Miandoab city. Based on the
results of physicochemical parameters, the Water Quality Index (WQINSF) was calculated.
Results: The result of the effects at the construction phase (-83) and operation phase (+137)
indicated that implementation and operation of the fish farming center of Miandoab have positive
effects. The results of the water evaluation showed that there was no significant difference in
temperature between study stations (P>0.05). The parameters of nitrate, phosphate, alkalinity,
ammonia, dissolved oxygen, pH, and BOD5 were significantly affected by different stations
(P<0.05). The highest and lowest levels of BOD5 in stations three and one were 12±0.001 and
5.5±0.707 mg/L, respectively and also the highest and lowest ammonia levels were observed at
1.16±0.156 and 0.01±0.001 mg/l in stations one and four, respectively.
Conclusion: With the implementation of the project, some difficulties, such as lack of water
caused by wasting it in soil channels, overall condition of fish farming activity in the region,
immigration from villages to urban areas, lack of employment and lower-income and welfare
of the people will be improved; accordingly, and a positive trend will be taken in the future.
According to the Water Quality Index (WQINSF), the first and second stations showed good
quality status and the third and fourth stations showed lower (average) status. Therefore, it is
recommended that all units be equipped with wastewater treatment systems.
