TREATMENT OF CARPS AT PHILOMETROIDOSIS

The article presents the results of determining the therapeutic efficacy of a new combined anthelmintic drug for carp philometroidosis. Invasion of carp before the use of the drug was 32%, with an invasion intensity of 4.25 parasites on fish. Therapeutic feeding was performed twice at a dose of 40 mg d.c. / kg of ichthyomass. Six days after the therapeutic feeding of the fish, according to the results of a helminthological study, 25 specimens of carp were established to have 100% extension of deworming.Philometroidosis causes great economic damage due to the partial death of young fish, 15–20% weight loss, culling of affected fish. Krasnodar region until the mid-80s. of XX century was safe for this disease, however, due to violation of the rules of quarantine of fish, phylomethoidosis began to be registered in pond farms. At present, it is also distributed among carp fish in natural water bodies with a low intensity of invasion.The disease is caused by the nematode Philometroideslusiana from the family Philometridae. Nematode females are rather large helminths of 90–160 mm long, up to 1 mm wide, localized under scales in scale pockets.Only carp, common carp and their hybrids of different ages are subject to philometroidosis. As fish age, infection usually increases.
