A site selection study to develop marine artificial reefs of coast of Chabahar in Sistan and Balochistan province region- Ramin

Abstract

Coasts and Islands have destruction due to over harvesting from ecosystems and other activities by humans and natural, These caused many aquatic as demersal fishes has endangered in Persian Gulf and Oman Sea. The artificial reef is one way or method that can improve the environment and restore the aquatic. Artificial reefs are manmade materials deployed under water in order to improve invironment and increase the exploaitation of fishing area. Usage of artificial technic has developed due to increase of world pupolation and need to supply of protein, aim to restoring of natural spicialy rehabilitation of demersal fishes. It has effecte to increase the production in order sustainable exploitation. According to the fisheries plan, Study has started for development of artificial reefs and enabling for marine improvment in order to protection of marine resources and increase marine production. In this regard, the first step was study of capable site selection for mentioned subject that Iranian fisheries Sciences Research Institute has studied the coastal area with a radius of three kilometers in Ramin Port in Chabahar region. In this study some devices have used as depth meter, CTD, grab and special boat for determine of bottom status and measured physical and chemical factors. These data have used to determine the potaincials of stadied area for development of artificial reefs in studied area and for improvement and effectiveness of marine environment, increase production and more occopation of fishermen.
