Dynamics of a Fish Ectoparasite Population: Opportunistic Parasitism in Argulus Japonicus (Branchiura)

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.

Fish Lice (Argulus japonicus) in Goldfish (Carassius auratus).

Comparative medicine, 2016
Fish 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.

The male reproductive system and mechanism of sperm transfer in Argulus japonicus (Crustacea: Branchiura)

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 ...

Mixed infection of Argulus japonicus and Argulus siamensis (Branchiura, Argulidae) in carps (Pisces, Cyprinidae): loss estimation and a comparative invasive pattern study

Crustaceana, 2012
The genus Argulus is economically one of the most important taxa of crustacean ectoparasites in freshwater aquaculture systems throughout the world. This study investigates the occurrence and effect of a mixed infestation of two species of Argulus, Argulus japonicus Thiele, 1900 and Argulus siamensis Wilson, 1926, in a carp culture farm in Mandi ...

The Ultrastructure of the Newly Hatched Argulus Japonicus Thiele, 1900 Larvae (Branchiura)

Crustaceana, 1995
Abstract Fcrtilized Argulus japonicus Thiele, 1900, eggs were hatched in the laboratory. The morphology of the first developmental stage was studied by means of scanning electron microscopy and light microscopy. The surface topography of the carapace and appendages are described.

New Host and Distribution Records for the Freshwater Fish Ectoparasite Argulus japonicus (Crustacea: Branchiura: Argulidae)

Comparative Parasitology, 2013
ABSTRACT: The branchiuran parasite Argulus japonicus (Crustacea: Branchiura: Argulidae) was collected from the body surface of the Rosy bitterling Rhodeus ocellatus from Kumamoto Prefecture, Kyushu, Japan. The present study represents the first record of A. japonicus obtained from Kyushu. Rhodeus ocellatus is a new host for A. japonicus.

Laying, development and hatching of eggs of the fish ectoparasite Argulus japonicus (Crustacea: Branchiura)

Journal of Zoology, 1986
Egg laying of the fish‐louse Argulus japonicus was observed and examined experimentally. The effect of temperature on development time and hatching yielded an inverse exponential function. Hatching started after 61–10 days in a temperature span of 15–35 °C. Eggs are laid in strings on hard substrata and covered by a gelatinous material.

Argulus JaponicusThiele, 1900 (Crustacea: Branchiura)—A new record for New Zealand

New Zealand Journal of Marine and Freshwater Research, 1967
Summary A single mature female of Argulus japonicus is recorded. The specimen was probably introduced with goldfish from South East Asia. Differences between its actual morphology and details in several published accounts are discussed. Discrepancies are believed to be due to errors or omissions in the latter.

Molecular identification of Argulus japonicus in red cap oranda goldfish (Carassius auratus) in Multan, Pakistan

2020
Fish aquariums provide the foremost characteristics of morphology and identification of the genus Argulus (Crustacea: Branchiura). Member of genus Argulus, or fish louse are ectoparasites of fresh-water fishes. The present study was investigated the molecular analysis of Argulus japonicus.
