Chemotherapy of ectoparasite, Ergasilus ceylonensis of Asian cichlid, Etroplus suratensis

Journal of Applied Ichthyology, 1988
Summary Therapeutic control of crustacean ectoparasite Ergasilus ceylonensis on gills of Asian cichlid Etroplus suratensis inhabiting Negombo estuary and its tributaries on the west coast of Sri Lanka was investigated using formalin, gammexane, potassium permanganate, 3,4 Dichloropropyoanilyde and fenitrothione.

Ergasilus arthrosis n.sp. (Copepoda: Cyclopoida) and the Taxonomic Status of Ergasilus versicolor Wilson, 1911, Ergasilus elegans Wilson, 1916, and Ergasilus celestis Mueller, 1936, from North American Fishes

Journal of the Fisheries Research Board of Canada, 1969
The type specimens designated by Wilson (1911, Proc. U.S. Natl. Museum 39: 263–400) for Ergasilus versicolor do not agree with the description of that species but are conspecific with Ergasilus elegans Wilson, 1916; therefore, E. elegans is reduced to synonymy with E. versicolor, and a new description of E.

The life-cycle of Ergasilus briani Markewitsch, 1993 (Copepoda: Poecilostomatoida)

Systematic Parasitology, 1996
The life cycle of Ergasilus briani is shown to consist of six nauplius stages, five copepodid stages and the adults. Only the adult female is parasitic. The free-living stages are described in detail. The presence of three aesthetascs on the antennules of all copepodid stages and the adult is noted for the first time. Unusual aspects of E.

A redescription of adult females of Ergasilus briani Markewitsch, 1933 (Copepoda: Poecilostomatoida)

Systematic Parasitology, 1993
The adult female of Ergasilus briani Markewitsch, 1933 (Crustacea: Copepoda) is redescribed using scanning electron and light microscopy. The taxonomic history of E. briani is reviewed. It is confirmed that E. briani and E. minor Halisch, 1934 are synonymous. The known distribution of E. briani in Britain is noted.

Ergasilus (Copepoda: Cyclopoida) Infestation of Coho and Chinook Salmon in Lake Michigan

Transactions of the American Fisheries Society, 1976
Abstract Parasitic copepods were found on 1.6% of coho salmon, Oncorhynchus kisutch, 8.8% of chinook salmon, Oncorhynchus tshawytscha, and 15.8% of yellow perch, Perca flavescens, from Lake Michigan. Ergasilus luciopercarum Henderson parasitized chinook salmon and yellow perch, while Ergasilus nerkae Roberts was observed only on coho salmon.
