Review on Polypodium Hydriforme Infestation of Sturgeon Eggs and Its Implications in Species Conservation

Abstract

Polypodium hydriforme is the only known parasite adapted to intra-cellular parasitism of sturgeon oocytes, thus affecting the delicate life balance of these endangered species. Aquatic ecosystems are often shaped by intricate interactions between various organisms, each playing a distinct role in the overall health and sustainability of the environment, parasites on the other hand pose no beneficial roles and are a threat especially for fragile or declining species. Sturgeons, which are endangered and ecologically important fish species, serve as hosts for this parasite during their crucial reproductive phase. The presence of Polypodium hydriforme in sturgeon eggs has prompted investigations into its effects on both the host’s reproductive success and the broader aquatic ecosystem. Stating the intricacies of this parasitic interaction is essential not only for unravelling its evolutive adaptations but also for ensuring the conservation of sturgeon populations and the preservation of aquatic biodiversity as a whole.
