Interaction of Temperature, Salinity, and Chlorine-Produced Oxidant (CPO) Exposures in Reducing Mortalities from the Estuarine Fungal (Now Protistan) Parasite (Labyrinthomyxa Marina, Formerly Dermocystidium Marinum, Now Perkinus Marinus) Infecting the Eastern or American Oyster, Crassostrea Virginica (Gmelin): Application for Oyster Aquaculture in South Carolina Coastal Impoundments

摘要

The study examined several cost-effective techniques for control of L. marina infections in the pond aquaculture setting, including: (1) temperature manipulation (low-temperature exposure to retard gonadal development at high and low salinities); (2) salinity manipulation at ambient temperatures (under high- and low-salinity conditions); and (3) the potential use of chlorine (NaOCl at nominal concentrations as an aquatic fungicide (under both high- and low-salinity conditions at ambient temperatures). Results suggest that the combination of low-salinity and chlorine-produced oxidant (CPO) exposure may provide a cost-effective, practical, management technique for controlling oyster mortality resulting from L. marina infections in natural impoundments.
