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

Journal 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 ...

Monogenean Sparicotyle chrysophrii: The major pathogen of the Mediterranean gilthead seabream aquaculture

Reviews in Aquaculture, Volume 16, Issue 1, Page 287-308, January 2024.
Sparicotylosis has been present in Mediterranean aquaculture of the gilthead seabream for the past 25 years, yet disease management and treatments are not effective. This is further jeopardised by global warming and resistance of Sparicotyle chrysophrii to available anthelminthic compounds.

In Vivo Challenge Trials with Dietary Antiparasitics Reveal New Insights into the Practical Use of Fenbendazole against Sparicotyle chrysophrii (Monogenea) Infection in Sparus aurata (Teleostei)

Aquaculture Research, Volume 2024, Issue 1, 2024.
The microcotylid Sparicotyle chrysophrii is one of the most harmful parasites for the aquaculture of the gilthead seabream Sparus aurata, for which effective treatments are needed. The efficacy of dietary praziquantel (PZQ, 30–50 mg kg body weight−1 day−1), emamectin benzoate (EMB, 0.015–0.050 mg kg BW−1 day−1), and fenbendazole (FBZ, 40–75 mg kg BW−1 ...

Relationship between Water Quality Parameters and Parasite Infestation in Farmed Oreochromis niloticus in Selected Rift Valley Counties, Kenya

Aquaculture Research, Volume 2024, Issue 1, 2024.
Globally, parasitic infections hinder aquaculture productivity and sustainability. Improper water quality parameters reduce fish immunity, make them susceptible to parasites, and enhance parasitic proliferation in culture systems. Subsequently, this study aimed to determine the prevalence and intensity of ecto‐ and endo‐parasite infesting Oreochromis ...

Morphological and genetic identification of the gill monogenean parasite (Diclidophora merlangi) that infects Twobar Seabream Fish (Acanthopagrus bifasciatus) in the Arabian Gulf, Saudi Arabia

Helminthologia
Ectoparasites, particularly monogeneans, negatively affect fish health and growth. This study identified monogenean parasites in the twobar seabream, Acanthopagrus bifasciatus (Sparidae), inhabited the Arabian Gulf (Saudi Arabia). Following that, forty A.
