Kudoa sciaenae (Myxozoa: Multivalvulidae) cysts distribution in the somatic muscles of Stellifer minor (Tschudi, 1844) (Pisces: Sciaenidae)

open access: yesMemorias do Instituto Oswaldo Cruz, 1992
The distribution of Kudoa sciaenae cysts (Myxozoa), in terms of intensity and prevalence, in the somatic muscles of the sciaenid Stellifer minor, shows an apparent preference for the anterior body region, including the head. The observed preference seems

Unclear host taxonomy hinders parasite studies: An up‐to‐date checklist of the protozoan and metazoan parasites of Phoxinus minnows (Teleostei: Leuciscidae)

open access: yesJournal of Fish Biology, Volume 105, Issue 6, Page 1501-1539, December 2024.
Abstract Phoxinus minnows are small freshwater fish found throughout Eurasia. The taxonomy of this genus is still under investigation, and new species are regularly described. They are frequently introduced outside their native range due to their use as live bait for angling, and such fish introductions can have diverse impacts on the recipient areas ...

Fish Gut Metabarcoding Detects Diets and Parasites Simultaneously

open access: yesEnvironmental DNA, Volume 6, Issue 6, November–December 2024.
Understanding dietary habits and trophic niches of species is crucial for the conservation and management of species and ecosystems. We applied a multimarker metabarcoding approach to assess the diet and parasites of commercially exploited beaked redfish (Sebastes mentella).

Re‐evaluation of certain aspects of the EFSA Scientific Opinion of April 2010 on risk assessment of parasites in fishery products, based on new scientific data. Part 2

open access: yesEFSA Journal, Volume 22, Issue 11, November 2024.
Abstract The objective of this opinion was to determine if any wild caught fish species, originating from specific fishing grounds and consumed in the EU/EFTA could be considered free of zoonotic parasites. In this Opinion the term ‘fishery products’ only refers to fresh finfish.

Communities of metazoan parasites in seven sympatric skate species (Elasmobranchii, Rajidae) from the English Channel and Celtic Sea differing in conservation status

open access: yesJournal of Fish Biology, Volume 105, Issue 3, Page 975-987, September 2024.
Abstract Elasmobranch populations are in steep decline mainly due to overfishing bycatch, but parasites may accelerate the collapse of vulnerable and/or highly parasitized species. We therefore studied metazoan parasites of Rajidae from the northeast Atlantic: vulnerable Leucoraja fullonica, near‐threatened Raja brachyura, Raja clavata, Raja ...

Investigation on parasitic infestation of Labeo rohita (Hamilton, 1822) in the south‐western region of Bangladesh

open access: yesVeterinary Medicine and Science, Volume 10, Issue 4, July 2024.
Over the study, 180 L. rohita specimens were examined,, revealing the presence of six distinct parasite species, consisting of endoparasites. Through microscopic examination, a total of 323 parasites were investigated, categories including Cestode, Nematode, Acanthocephala, Trematode and Digenia, predominantly residing in the intestines and liver of L.
