Abstract

The application of an electrolytic water treatment technique in a Pacific white shrimp (Litopenaeus vannamei) closed hatchery system was investigated in three experiments. The first experiment studied the chlorine concentrations produced from an electrolytic system with different
electric current and water salinity levels in a static water system. The second experiment studied the optimal electric currents and water flow rates for water treatment. The last experiment compared the closed hatchery system with an electrolytic system to an open system using chlorine powder for water treatment. It was found that in the static closed-water system, chlorine concentration increased with an increase of the duration of flow electric current and water salinity. While in the lotic condition, the optimal flow rate of water into the electrolytic system was 2.5 l/min and produced 11.4 mg/l of chlorine with an applied amperage of 1.6 A. This level was suitable for water treatment and could be applied in the Litopenaeus vannamei closed hatchery system for at least three crops. Although the system could reduce the usage of chlorine powder, it had a lower survival rate and a greater nitrite-nitrogen level than the control.
