Distribution of niclosamide residues in meat and internal organs of common carp

Abstract

Niclosamide is applied for the treatment of the disease of common carp hatchlings caused by Bothriocephalus acheilognathi. One of the main characteristics of this drug is a short half-life in water. A series of experiments were performed to determine the distribution of niclosamide residues in the organs and meat of the carp, in controlled conditions. It was shown that 72.42% of niclosamide was deposited in the liver, 18.79% in the kidney and 7.79% in the spleen. However, only about 3% of deposited niclosamide was detected in meat. This drug provides rapid and effective treatment of fish, completely eliminating the tapeworms.
