All remaining fish in the japonidus were inspected visually, and no other parasites were seen. Flick G, Wiegertjes GF. As soon as Argulus is identified, management and treatment are recommended due to the potentially rapid escalation of infection. The room into which the fish were received contained 2 self-contained, recirculating, aquatic rack systems, one to supply fish for research and the other to hold incoming fish.

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

Incoming fish, particularly wild-caught or pond-raised stock, should be quarantined, observed, and sampled to minimize the risk of introduction. Acknowledgments We thank Jamieson Greaver maponicus taking the pictures and Kelly Garner for her contribution in creating the figures.

All new arrivals are quarantined for at least 3 wk. The image of infected leukocytes infested by Argulus japonicus were 8. Laying, development, and hatching of eggs of the fish ectoparasite Argulus japonicus Crustacea, Branchiura.

Kismiyati Ectoparasitic infestation Argulus japonicus on mascokoki fish Carassius auratus and efforts of fish control with fish of Sumatra Surabaya: University of Puerio Rico One of the constraints of freshwater fish cultivation is ectoparasite infestation Argulus japonicus.

We thank Jamieson Greaver for taking the pictures and Kelly Garner for her contribution in creating the figures. Manual inspection of the other 8 fish cohoused with the index fish disclosed lice on the anal fins of 2 additional goldfish Figure 1.

The filters include a mechanical-fiber pad, a fluidized bed biofilter, and a mechanical—chemical fiber sleeve with carbon. Many fish host this louse, which is probably able to parasitize almost every species of freshwater fish.

Juvenile Argulus lice attach to the host by means of the claws, whereas adults attach by means of a pair of modified suckers commonly referred to as maxillules. Journal List Comp Med v. Sign up for new issue notifications. Argulus fish louse infections in fish.

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

J Crustacean Biol Lesions inflicted by the parasites often become necrotic and ulcerated, leading to secondary infections. As soon as any Argulus organisms are identified, management and treatment are recommended because infections can escalate rapidly. Source water should be evaluated to ensure that it is not a route for the introduction of argulid eggs.

A The branchiuran parasite Argulus japonicus collected from the caudal and anal fins of 3 goldfish Carassius auratus. While feeding on the host, Argukus species insert a preoral stinger to inject digestive enzymes into the body of the fish, aggulus the lice suck out liquefied body fluids by using their proboscis-like mouth.

Other information The parasite is effectively removed by the trichlorfon immersion, but repeated treatments are needed because it does not kill the parasite eggs.

Health hazard Since this parasite is not infectious to human, it is harmless in food hygiene.
