Abstract
Despite the wide abundance, accessibility, and distribution of sympatric stingrays Hypanus sabinus and H. say in the Indian River Lagoon (IRL) estuary, their parasite-host interactions remain undescribed. Beginning in July 2023, the Florida FWC Fisheries Independent Monitoring (FIM) program and Nova Southeastern University have taken monthly specimen collections from differing IRL regions during FIM surveys. Preliminary species examinations have focused primarily on the spiral valve (intestine), gills, stomach and nasal fosse of stingrays using standardized parasitological necropsy procedures. Parasites recovered to date include several parasite taxa belonging to Cestoda, Monogenea, and Digenea. We evaluate these results in the context of previously published parasite survey information for this host genus.
