Context of diversification of the viviparous Gyrodactylidae (Platyhelminthes, Monogenoidea) [PDF]
Zoologica Scripta, 2003 Using four criteria proposed a decade ago by Brooks & McLennan to identify a case of adaptive radiation indicates that the evolutionary history of the viviparous clade of the Gyrodactylidae is dominated by nonvicariant processes. The viviparous clade, with 446 species, has significantly more species than its sister clade (one species), and high ...

18S rRNA Metagenomic Analysis of Nodular Gill Disease in Swiss Rainbow Trout (Oncorhynchus mykiss). [PDF]
J Fish DisABSTRACT Nodular gill disease (NGD) is a serious proliferative gill condition that affects farmed salmonids, particularly in Europe. While the cause of NGD remains unknown (and maybe multifactorial), various amoebae are often isolated from the gills of affected fish and can in some cases be seen associated with lesions by histopathology.

Improving tilapia biosecurity through a value chain approach
Reviews in Aquaculture, Volume 15, Issue S1, Page 57-91, February 2023., 2023 Abstract Tilapia aquaculture is a major source of animal protein, with global production reaching over 6 million tonnes in 2020. The rapid growth of the tilapia sector has led to a number of emerging disease threats and subsequent production losses. Risk analysis can provide a targeted approach for improving biosecurity in the tilapia sector.

Infrapopulation dynamics of Gyrdicotylus gallieni (Monogenea: Gyrodactylidae)
Parasitology, 1994 SUMMARYGyrdicotylus gallieni is a viviparous gyrodactylid monogenean that infects the buccal cavity and pharynx oi Xenopus laevis laevis.
