Mixed infections and hybridisation in monogenean parasites. [PDF]

PLoS ONE, 2012
Theory predicts that sexual reproduction promotes disease invasion by increasing the evolutionary potential of the parasite, whereas asexual reproduction tends to enhance establishment success and population growth rate.

Monoterpenes: Functional Additives for Reducing Antibiotics in Aquaculture

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture is a rapidly growing industry that supplies fish for global consumption. However, the intensive production practices have resulted in disease outbreaks, largely driven by the misuse of antibiotics. Natural alternatives, such as monoterpenes, which are biocompounds derived from essential oils obtained from plants like thyme and ...

Elemental Requirements of Rearing Seawater for Unfed Larvae of the Japanese Eel (Anguilla japonica Temminck and Schlegel)

Aquaculture Research, Volume 2026, Issue 1, 2026.
This study assessed the influence of salinity and element composition of rearing seawater on unfed Japanese eel (Anguilla japonica) larvae at 5 days after hatching (DAH). First, no significant differences in larval survival were found between natural and artificial seawater across various container materials and sizes (50mL–20 L).

Taxifolin Modulates Transcriptomic Response to Heat Stress in Rainbow Trout, Oncorhynchus mykiss

Animals, 2022
Taxifolin is a natural flavonoid known for its antioxidant, anti-inflammatory, and antiproliferative effects on animals. In this work, we have studied the effect of this compound on rainbow trout, Oncorhynchus mykiss, a major object of aquaculture, under

Zingiber officinale (Ginger), Curcuma longa (Turmeric) and Cymbopogon nardus (Lemon Grass) Essential Oils Have Anti‐Dactylogyrideans Potential in Colossoma macropomum Cuvier 1816 (Tambaqui)

Aquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT Essential oils are composed of secondary metabolites derived from medicinal plants and have bioactive properties, such as antiparasitic activity. This study investigated the in vitro anti‐dactylogyridean efficacy of the Zingiber officinale, Curcuma longa and Cymbopogon nardus essential oils, as well as the acute toxicity for Colossoma ...

Gyrodactylids parasitizing salmonids in Brittany and Western Pyrénées water basins: epidemiological features of infection and species composition

Knowledge and Management of Aquatic Ecosystems, 1999
In the first part of a national survey of gyrodactylid parasites, with spécial référence to Gyrodactylus salaris, funded by French administrations, two water basins harbouring Atlantic salmon were sampled : Brittany (7 rivers and 3 restocking farms) and ...

A new species of Gyrodactylus (Monogenea, Gyrodactylidae), an ectoparasite from the endemic Iranocichla hormuzensis (Teleostei, Cichlidae), the only Iranian cichlid

European Journal of Taxonomy, 2012
Iranocichla hormuzensis occupies a biogeographically peculiar position. This endemic of southern Iran is the only Iranian cichlid. While it is phylogenetically related to African oreochromine members of the cichlid family, it remains unclear how it has ...

New records of nine monogenean parasites infesting non‐native freshwater fish species in New Zealand

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1052-1068, December 2025.
ABSTRACT Twenty‐one non‐native freshwater fish species have established populations in New Zealand, yet only two have been reported with monogenean infestations; grass carp, Ctenopharyngodon idella (Valenciennes in Cuvier and Valenciennes, 1844) and western mosquitofish, Gambusia affinis (Baird and Girard, 1853), each with two identified monogenean ...

Comparative Genomic Analysis of Co‐Occurring Hybrid Zones of House Mouse Parasites Pneumocystis murina and Syphacia obvelata Using Genome Polarisation

Molecular Ecology, Volume 34, Issue 21, November 2025.
ABSTRACT Parasites are expected to hybridise in similar ways to free‐living organisms, although this may be modified by their reduced genome architecture. Recombinant strains and taxa of hybrid origin can be studied in nature where hosts come into secondary contact. Here we apply genome‐wide analysis to parasites from a contact previously characterised
