This study was carried out to describe the relationship between environmental factors and development of cnidarians communities in artificial habitats ofBahrekan coastal water in Northwest of Persian Gulf.The samples were collected by SCUBA diving and (quadrates of 0.25×0.25m) 4 sites seasonally between May2009 up to February 2010. Determiningthe wet weight showed these artificial reefs are strongly dominated by cnidarians.Chemical and physical factors including temperature, salinity, Do, pH and turbidity in each season were measured and theirrelationships with biomass of cnidarianswerestudied.Total biomass of cnidarians did not show any significant difference for the sampling months(P<0.05). Moreover, this study revealed that there is anintensive correlation between biomass and salinity (R2= 0/82).The lowest correlation was observed between pH and biomass (R2= 0/21).
Keywords: Cnidarians, Artificial habitats, Environmental factors, Persian Gulf.
