Ecological Risk Assessment in the coastal areas of the Caspian Sea (Case study: Sturgeon fish farm Morvarid Ghoroogh-Talesh)

Today, with the increase in population, the amount of production in the aquaculture sector is expanding worldwide. As an emerging industry, this industry poses potential risks to the environment and humans. The use of risk assessment approaches is a very good way to manage the stresses of this industry on the environment. The science of risk assessment in the field of aquaculture is very new and is not very old in the world. The most important groups active in this field are EPA, FAO / UNESCO-IOC / WMO / WHO / IAEA / UN / UNEP and GESAMP (IMO. In the present review of the guidelines for ecological risk assessment for the aquaculture industry approved by the US Environmental Protection Agency (EPA) According to the evaluation of sturgeon farming in Ghorogh farms on the quality of the receiving ecosystem (Karganrud River and Caspian Sea) respectively in terms of pathogens with high risk potential, pharmaceuticals and disinfectants have high risk potential and for organic and nutrient content there is a medium risk potential (moderate risk of end factors can be attributed to the self-purification power of the river) which in management measures continuous monitoring and monitoring Investigating the potential of river self-purification as well as the status of plant and animal communities in affected ecosystems can increase the accuracy of the assessment and lead to more accurate management decisions.
