Description:
Azadegan aquaculture site is located 25 km south of Ahvaz in southern of Khuzestan plain. Primary study of Azadegan aquaculture site was done in 1992 with the aim of developing feasibility of warm water aquaculture and the second phase was done in 1996-1998 by Mohandesin Moshaver Pandam. Now, cyprinus carpio, Hypophthalmichthys nobilis, Hypophthalmichthys molitrix, Ctenopharyngodon idella), Barbus grypus) and Mesopotamichthys sharpeyi rear in this site. Considering special traits of Indian carps such as different level of production in earth pool, diet diversity, and more favorability for consumers, possibility of alternation with common carps, adaptability, growth and maturity in Khuzestan climate, this species can increase the efficiency of Khuzestan aquaculture industry as one of the poles of production in country. In this study the environmental impact assessment of the region was done because of the importance of Shadegan wetland as receiving waste area. Leopold matrix was used for assessment and quantifying environmental impacts of India carp aquaculture. Identification and prediction of effects were done based on the matrix. In using phase, 101 effects were identified which 34 were negative and 67 were positive. 18.8 percentage of effects were physic-chemical, 25.7% was biologic and ecologic and 55.5% was in socio-economic environment. In the operation phase, from all of the anticipated effects in physic-chemical environment 5 effects were positive and 14 effects were negative and in ecologic-biologic environment 17 effects were negative and 9 effects were positive. In socio-economic environment from 56 effects 3 were negative and 53 were positive. In order to summarizing the scores in environmental impact assessment matrix, final scores concluded from weighted scores of different environments including physic- chemical, ecological-biological and socio- economic environments. These scores showed that physical activities will have negative effects due to sewage production and negative effect on water resources. However, because of positive effects in socio-economic and ecologic environments, the final score in +83 that shows general result will be positive especially in economic and social environment. Due to the positive effects of the project on the economic and social conditions such as improving living conditions, creating job opportunities due to culturing this species and changing patterns of employment, increasing income levels at local, provincial and even national scale, increasing the price of land, supporting lateral and related industries, including hatcheries, fish-producing industries, manufacturing and processing industries and conversion, marketing and export, as well as the pharmaceutical industry (veterinary drugs), education development of specialized human resources and its role in the development of aquaculture projects in compliance with the recommendations of management and control is permitted.
