Salinity is known as one of the most challenging problems in aquaculture and agriculture. This issue has posed more difficulties to the shoreline of the Persian Gulf. Halophyte plants with their high potentials of absorbing salinity from soil and water are able to enhance the biopurification process in the environment. Hydroponic is a biointegrated food production method which links recirculating aquaculture, plant and flower as well as herb production. In this study, the possibility of application of hydroponic in decreasing the high salinity of aquaculture industry in water of shrimp culture ponds was investigated. Three economic halophyte species, including Avicennia marina, Salicornia europaea and Suaeda martima were cultured, 66 individuals per species, under the salinities of 25, 35, 45, and 55 ppt under hydroponic conditions. Firstly, the average initial sizes of the aforementioned species under different salinities were measured. Secondly, the average of plants’ growth, their survival percentages and phenotype characteristics were investigated. The results suggested low effect of decreasing salinity under hydroponic conditions. However, Suaeda martima has the most potential effect on salinity compare to others.¬ Therefore, application of this species in waters with low levels of salinity is advisable.
