The aim of the present study is the environmental impact assessment of tilapia (Tilapia nilotica) farming
project in brackish water of Bafgh, with goals to achieve localization of technology and knowledge of tilapia fish
production, employment and the possibility to controlled development in other areas. Desired range, located in
northwest of Daranjir desert (Inland Salt Water Fishes Research Station, Bafgh). Total area used for the project
includes three indoor hall for breeding operation, nursery (juvenile breeding) and fattening. Besides these, three
3000 m 3
available earth ponds has been considered as a potential area breeding after setting apart the quarantine.
In order to achieve sustainable development of breeding this fish, impact assessment of this project development
in which both environmental and social - economic effects are considered, it seems essential and project will be
accomplished more confidently. So, after considering the technical characteristics of the project, the immediate, direct and indirect impact area were determined and environmental aspects of area identified. Matrix methods
was utilized for the environmental impact assessment. The most important operational activities, including
greenhouse structures implementation and water conveyance facilities, including excavation and embankment, channel, piping, lining of channels and their accessories including inlet and outlet valves, concrete, stone, porcelain, walling up , roof, construction of drainage network and access roads. Based on investigation, accessibility of the region, compatibility with the other land uses, lack of monuments in the area, not covered
with the sensitive habitats range, the lack of permanent river flow, low quality of underground water and end up
underground water flows in downstream desert and evaporated which result in impossibility of escaping
introduced fish from the farm and the use of existing spaces in the first half of the year to product lead to make
fewer infrastructure costs and increase revenue, are the main criteria for the sustainable development of this
species culture in the area. Considering the executed studies and results of the matrix assessment construction
and operation phases, it was concluded that there is no considerable destructive impacts related to the project. Therefore due to the fact that 50% of means in rows and columns of the matrix were not less than -3.1 so, we
proposed execution of it with rehabilitation plans. Therefore, some strategies and plans to consider reducing the
negative effects and enhance positive effects of the project, including monitoring programs, were proposed.
