Shrimp wastewater discarded directly into the environment can impact the stability of adjacent ecosystems. This study evaluated the following: the growth of halophytes cultivated with shrimp culture water and water from an estuary; the interaction between the integrated cultivation of halophytes and shrimp in water recirculation systems; and physicochemical variables of wastewater before and after being treated with halophytes. Two bench experiments were carried out using fiber boxes to cultivate the halophytes. In both experiments, growth and initial and final mass of the plants were measured weekly. The relative and absolute growth rates were measured for the mass and height of the plant species. The absolute growth rates for Batis maritima of systems one and two of the first experiment, and of the system of plants of the second experiment, were 1.12 cm/d, 4.40 cm/d and 3.55 cm/d, respectively. The data indicated that halophytes cultivated with shrimp wastewater had higher growth and that the nutrients of the culture medium were reduced in the presence of plants.
