The production response of cauliflower to added sea salt has been investigated for 72 days in media based aquaponic system. Because of euryhaline nature, tilapia fingerlings (initial mean length5.15 ± 0.84 cm and weight 2.46 ± 1.23 g) were released in fish tanks. Nine different sets of aquaponics were run under three treatments (T1, T2, T3) each with three replications (R1, R2, R3). Sea salt was added in the fish tanks to make the recirculating water saline at 1 ppt in T1 and 2 ppt in T2 whereas fish tanks under T3 were free from salt addition as control. Commercial pellet feed was given to the fish and fish tank waste water to the cauliflower plants for growth. Both the fish and cauliflower respond better in T2. Nutritional profile and production of cauliflower were significantly higher in T2 (13.22±1.58 tons/ha) than T1 and T3. Further research needed for better understanding.
