Impact of Removing Dietary Supplementation on Serum Nutrient Concentrations in a Managed Population of Southern Stingray (Dasyatis americana)

The Walt Disney Company manages two distinct populations of female southern stingrays (Dasyatis americana) at The Seas, Orlando, FL, and at Castaway Cay, Bahamas. Stingrays are housed in artificial (Orlando) or natural (Bahamas) seawater.  We previously reported significant differences between these two populations based on eight years of routinely collected serum data.1 The aim of this study was to assess...

Comparative serum analysis of free-ranging and managed green moray eels (Gymnothorax funebris) and relationship to diet fed to eels under human care

Green moray eels (Gymnothorax funebris) under human care are reported to have elevated plasma cholesterol and triglyceride concentrations with associated development of lipid keratopathy (Clode et al. 2012). Nevertheless, serum trace mineral and vitamin analyses have not been assessed, and the complete nutrient content (cholesterol, vitamins, and minerals) of managed eel diets has also not been reported (Clode et al....
