Abstract
The spread and age dynamics of mixed infections in 6 types of fish caused by Trichodina spp., Trichodinella spp. and other parasites are studied. The method of complete parasitological autopsy of fish was applied. The differentiation of fish parasites was conducted according to practice standards. During the examination of 100 fish of various types the following infection level has been determined: in carp – 52 %, European carp – 46, grass carp – 24, silver carp and trout – 28, bighead – 14 %. 29,4 % of fish were infected with ecto- and endoparasites. Trichodina spp. and Trichodinella spp. were detected in 18 % of European carp, 14 % of grass carp, 12 % of trout, 10 % of silver carp, 8 % of carp, 4 % of bighead. Of the total amount 26,8 % fish were infected with Trichodina spp., Trichodinella spp., Ichthiophtirius sp. and Dactylorus sp., 31,2 % – with Trichodina spp., Trichodinella spp., nematodes and cestodes. The infection caused by Trichodina spp., Trichodinella spp. was increasing with age of the fishes and made in tiny fish 6 %, fingerling fish – 10, 2 years old fish – 20, 3 years old – 30, five years old – 39 % at intensity of infection 19,2 expl./fish, 28,9; 36,7; 58,8 and 70,5 respectively. Carp fingerlings were infected with 2–3 species of Trichodina spp., 6 species of Trichodina spp. and Trichodinella spp. were detected in 3 years old fishes. A high level of infection leads to decreased productivity, condition factors of fish, technological, commercial and sanitary characteristics of fish production.
Keywords: fish, mixed infection, Trichodina spp., Trichodinella spp., Kabardino Balkarian Republic.
