Abstract

Studies to determine the feasibility of using ozone to disinfect seawater for use in controlled environment shrimp culture were run at the University of Arizona-University of Sonora Environmental Shrimp Culture Station at Puerto Penasco, Mexico. Ozone was injected into seawater containing known natural populations of Vibrio spp, and known introduced populations of Fusarium solani. Total residual oxidant (TRO) concentrations and total viable plate counts for these pathogens were made during and post ozonization. TRO at a concentration of 2. 6mg/1 was sufficient to kill greater than 99. 9% of the Vibrio spp. present in the seawater within a 5-min exposure period. Greater than 99. 9% of the introduced conodiospores of F. solani were killed within 5 minutes after exposure to approximately 2. 1 mg/1 TRO.
