Survival and Physiological Responses of Juvenile Red Drum Exposed to Hypersalinity and Elevated Temperatures Academic Article uri icon


  • 2016, American Fisheries Society. Fingerling Red Drum Sciaenops ocellatus were held in water recirculating systems for 45 weeks under selected combinations of temperature and salinity: 30C and 35 (reference environment), 34C and 45, or 34C and 55. At the end of the culture period, condition factor, hematocrit, plasma osmolality, plasma lactate concentration, plasma glucose concentration, and liver glycogen content were determined. Responses of fish in the warm, hypersaline treatments did not differ significantly from fish in the reference treatment. Based on the results of this study, juvenile Red Drum can tolerate warm, hypersaline conditions for several weeks with no apparent detrimental effects if slowly acclimated to environmental temperature and salinity as long as food is not limiting and other water quality characteristics are acceptable.
