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).

Parasitic Infections of Freshwater Fish in Kenya: Prevalence Patterns, Ecological Drivers, and Implications for Aquaculture Sustainability

Journal of Parasitology Research, Volume 2026, Issue 1, 2026.
Fish parasitic infections present a growing threat to freshwater aquaculture in Kenya, affecting fish health, reducing productivity, and limiting the economic potential of small‐scale and commercial farms. This review provides the first consolidated national checklist of freshwater fish parasites in Kenya, synthesizing evidence from lakes, rivers, and ...

Aggregation and negative interactions in low-diversity and unsaturated monogenean (Platyhelminthes) communities in Astyanax aeneus (Teleostei) populations in a neotropical river of Mexico

International Journal for Parasitology: Parasites and Wildlife, 2019
We studied monogenean communities of 11 populations of Astyanax aeneus (Günther) separated by small geographical distances along 60 km of the Lacantún river in Chiapas, Mexico, in February and August 2012. We found 12 monogenean taxa. Amongst these, five

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 ...

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 ...

Fine structural observations on oocyte development in monogeneans

Parasitology, 1976
SummaryThe ultrastructural changes accompanying oocyte differentiation in the ovaries of the monogeneans, Diclidophora merlangi, Diplozoon paradoxum and Calicotyle kröyeri have been described. In each case, oogenesis in the ovary proceeds as far as meiotic prophase in the primary oocyte.

Compound sensilla in monogenean skin parasites

Parasitology, 1969
The fine structure of two kinds of compound presumed sense organs from the heads of three skin parasitic monogeneans Gyrodactylus sp. Entobdella soleae (larva only) and Acanthocotyle elegans is described. One kind of compound receptor consists of a number of associated sensilla, each ending in a single cilium (the spike sensilla of Gyrodactylus and the
