In January 2020, a mortality event was documented in endangered Pallid Sturgeon (Scaphirhynchus albus) at the Neosho National Fish Hatchery (Neosho, MO, USA). Moribund fish appeared emaciated, with hemorrhages on fins and rostrums. Mortality steadily increased, prompting an investigation into cause. No viral or bacterial pathogens were detected; however, high number of novel Gyrodactylus sp. id...

Previous research has shown that certain types of edible fish imported into Australia are infected with Euclinostomum/Isoparorchis digenetic trematodes. In the present study, Channa were examined for parasites which then morphologically identified to lowest taxonomic unit possible. Here we provide first Australian report Pallisentis sp. Van Cleave, 1928 (Prevalence (P) 35.9%) family Quadrigyrid...

The Aphanius fasciatus is an endemic fish species of the coastal Mediterranean region; and recently discovered in the northern Algerian Sahara. The aim of this study is to evaluate the infestation by ectoparasites on A. fasciatus in the new arid habitats where it was newly recorded. For this purpose, skin and gills of 95 fish caught in the Still Wadi (Still river), between September 2012 and Ju...

The sea lamprey Petromyzon marinus, which is among the most phylogenetically ancient vertebrates, is a hematophagous ectoparasite that feeds on vertebrates and is considered vulnerable in Europe but is a pest in the North American Great Lakes. We conducted a literature review of helminth parasites of P. marinus and investigated postmetamorphic lampreys sampled in rivers and northeast Atlantic c...
