Influence of environmental factors on Argulus japonicus occurrence of Guangdong province, China
Parasitology Research, 2014To assess the effects of abiotic factors on Argulus japonicus occurrence in freshwater ecosystem, we sampled fish, free-swimming parasites, and submerged objects from rivers, fish farms, and ponds (reservoirs and lakes) at 27 locations in Guangdong province, China, from July, 2010, to March, 2013. Friedman's test and Spearman's correlation coefficient (

The first report of phototaxis of fish ectoparasite, Argulus japonicus
Research in Veterinary Science, 2008We discovered positive phototaxis in the fish ectoparasite, Argulus japonicus (Subclass Branchiura). Positive phototaxis of A. japonicus showed circadian rhythmicity. The phototaxis of A. japonicus has a unique circadian rhythm, which has been reported in no other crustacean. No phototaxis was observed at 4:00. After this time, however, A.

The ultrastructure of the digestive cells of Argulus japonicus, Thiele 1900 (Crustacea: Branchiura)
Arthropod Structure & Development, 2009The ultrastructure of the cells of the digestive system of Argulus japonicus is described with the use of transmission electron microscopy. Specimens of Argulus japonicus were collected from the Vaal Dam in South Africa and fixed in Todd's fixative. The samples were post fixed in osmium tetroxide and embedded in resin.

Argulus japonicus: Sperm transfer by means of a spermatophore on Carassius auratus (L)
Experimental Parasitology, 2010The process of sperm transfer is somewhat enigmatic in Argulus, even though copulation has been witnessed. A breeding colony of Argulus japonicus was kept under laboratory conditions in order to study reproduction in the species. Pairs in copula were removed and studied with histology and scanning electron microscopy to describe the mechanism of sperm ...

Crustaceana, 1992
A Bloemhof Dam, Transvaal, et pendant une periode de 16 mois, l'ectoparasite Argulus japonicus Thiele a manifeste une nature opportuniste dans sa strategie reproductive et une mobilite diverse. Des oeufs ont ete pondus tout au long de l'annee et les femelles ont ete gravides de facon continue jusqu'a ce qu'elles atteignent 3 mm de longueur du corps. A.

Argulus japonicus Thiele, 1900 was originally described from China, but has spread to Europe, Africa, Australia, and North America. An ultrastructural description of A. japanicus has been done as one of the most common fish ectoparasites which has a high affect on fish life.

Journal of Morphology, 1993
AbstractThe histomorphology of the male reproductive system and surface morphology of the “peg‐and‐socket” in Argulus japonicus are described from serial sagittal and transverse sections and scanning electron micrographs. The prostate complex consists of a glandular part, a reservoir for storing the secretion, and an efferent duct opening into the ...

Fish Lice (Argulus japonicus) in Goldfish (Carassius auratus).
Comparative medicine, 2016Fish lice (Argulus spp; family Argulidae) are branchiuran crustaceans that parasitize both marine and freshwater fishes. Argulus spp can be a major threat to fish health, because heavy infestations can cause significant morbidity and mortality. In addition, fish lice are known to be the vehicle for other fish diseases.
