The first next-generation sequencing approach to the mitochondrial phylogeny of African monogenean parasites (Platyhelminthes: Gyrodactylidae and Dactylogyridae)

BMC Genomics, 2018
Background Monogenean flatworms are the main ectoparasites of fishes. Representatives of the species-rich families Gyrodactylidae and Dactylogyridae, especially those infecting cichlid fishes and clariid catfishes, are important parasites in African ...

Non‐Invasive Monitoring of Tetracapsuloides bryosalmonae by eDNA: Influencing Environmental Parameters

Environmental DNA, Volume 7, Issue 5, September–October 2025.
We investigated influencing environmental factors on a previously developed eDNA‐based detection protocol for T. bryosalmonae. Specifically, water and air temperature, precipitation as well as bryozon presence and infection status were evaluated. Recommendations for a future eDNA‐based monitoring of T. bryosalmonae are provided.

The Disease Burden in Fish Farm Management: An Integrative View and a Specific Vision in Europe

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT In aquaculture, the interactions and balance—or imbalance—between the fish, the rearing environment, pathogens, and farm management determine the occurrence and impact of clinical diseases. The global assessment of the factors related to disease impact is commonly referred to as disease burden.

Inventarisation of Parasite in ”Dumbo” Catfish Clarias sp. from Bogor Region

Jurnal Akuakultur Indonesia, 2007
Outbreak of parasites can reduce aquaculture productivity or even cause mass mortality of fish. Few quantities of parasite infection may still be tolerated by the host, however high intensity of infection can impair to fish metabolism or even damage of ...

Sinoatrial Contracaeciasis in Johnny Darters (Etheostoma nigrum) and Plains Topminnow (Fundulus sciadicus) From the South Platte Drainage, Colorado

Aquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT Intra‐sinoatrial nematodes were incidentally recognized in wild‐caught Colorado Johnny Darters (Etheostoma nigrum, JD) in 2020–2021 and in Colorado Plains Topminnow (Fundulus sciadicus, PTM) in 2023‐2024. PTM and JD were evaluated histologically.

Evidence for cryptic speciation in directly transmitted gyrodactylid parasites of Trinidadian guppies. [PDF]

PLoS ONE, 2015
Cryptic species complexes are common among parasites, which tend to have large populations and are subject to rapid evolution. Such complexes may arise through host-parasite co-evolution and/or host switching.

Three's a crowd: The relationship among endoparasites, an epibiont and their Daphnia host

Oikos, Volume 2025, Issue 8, August 2025.
In freshwater communities, organisms interact in a variety of ways, including predation, competition and parasitism. Parasites are ubiquitous, playing an important role in shaping freshwater communities. Endoparasites live within internal organs of their host, while ectoparasites, also known as epibionts, are confined to the external part of the host's

Testing non‐lethal techniques for endoparasite detection and sex determination in pumpkinseed sunfish (Lepomis gibbosus)

Journal of Fish Biology, Volume 107, Issue 2, Page 406-418, August 2025.
Abstract Developing non‐lethal techniques to estimate parasite infection is critical for studying disease ecology in wild animals. We tested the effectiveness of coelomic ultrasonographic examination and plasma enzyme markers to detect liver infection with bass tapeworms Proteocephalus ambloplitis (Leidy 1887) as well as the effectiveness of ultrasound

Abiotic environmental factors contribute to spatial variation in boldness and exploration in guppies (Poecilia reticulata)

Journal of Fish Biology, Volume 107, Issue 2, Page 547-559, August 2025.
Abstract Research on wild fishes has tended to overlook the role of abiotic factors in shaping behaviours associated with boldness and exploration. This oversight could exist because small‐scale variation in the abiotic environment might seem unlikely to influence such behaviours. We challenged this assumption through research in the Trinidadian guppy (
