The pompano Trachinotus blochii is a very good species for mariculrure due to its high growth rate, hardy nature, but the possible of its culture in inland saline ground water have never been tried to explore the potential of this species. The objective of this work was to evaluate the survival of T. blochii in inland saline ground water. Hatchery bred juveniles of the T. blochii (average length: 5.4±0.44 cm, average initial weight: 3.8±0.09 g) were used in the present experiment. Three different salinities (5, 10 and 15ppt) were tested in triplicate. Groups of ten fishes were placed in plastic tanks with 100 L of inland saline ground water; which was continuously aerated and completely exchanged every 24h. Complete mortality of juvenlies in inland saline ground water without potassium supplementation was exhibited at 5 ppt, 10 ppt and 15 ppt within 12 hrs, 24 hrs and 60hrs respectively. The influence of ionic concentrations in inland saline ground water on T. blochii should be studied with more detail, with special attention to fortification of potassium and its effect on growth and other physiological parameters in order to determine the potential for T. blochii culture in inland saline ground water.
