Also known as: Păduchi de pește
Arguloza este infestația cu Argulus, un crustaceu ectoparazit plat, discoidal (păduchele de pește), care se prinde de piele și înotătoare și se hrănește cu sânge și lichide tisulare. Este o problemă frecventă la peștii koi și aurii de iaz. Mușcăturile provoacă iritație, infecție secundară și pot transmite alți patogeni.
The fish louse Argulus is a large, visible crustacean parasite that attaches to the body and fins of pond fish. Koi and goldfish are commonly affected, particularly after introduction of infested fish or plants.
The flattened, disc-shaped parasite is introduced with new fish, plants or pond water. It clings with suckers and a piercing stylet, feeding on the host and leaving wounds that invite secondary infection.
Visible greenish translucent discs moving on the skin, flashing and rubbing, red inflamed bite sites, restlessness, weight loss, and secondary bacterial or fungal infections at feeding wounds.
Diagnosis is by direct observation of the moving parasites on the fish or in the water; the louse is large enough to see with the naked eye.
Treatment includes manual removal of visible parasites, organophosphate or other licensed antiparasitic pond treatments, and repeated dosing to break the life cycle. Wound care and antibacterial support prevent secondary infection.
Quarantine new fish and plants, inspect arrivals carefully and avoid introducing untreated pond water.
