Biodiversity and invasion indicators of the parasitic fauna of kutum at the basins of the rivers Terek, Sulak, Samur, Aksai And Kuma with in Dagestan

Abstract

The species composition of parasitic worms in fish in the Russian Federation has a rich biodiversity, and consists of 96 species. This work is based on materials of our own research conducted in the main rivers of Dagestan: Terek, Sulak, Samur, Aksai, Kuma. In this case, the method of complete helminthological dissection of fish was used according to the method of K.I. Scriabin, modified for fish V.A. Dogel (1970). During the period of work, 480 pcs were investigated. Terek barbel. Microspores from each fish detected during autopsy of cysts were counted and the average invasion intensity (ind./ pcs) was calculated and the invasion intensity (%) was calculated in the context of the region’s water bodies. The fish underwent an incomplete parasitological dissection according to the method of Z.S. Donets, S.S. Shulman (1978) with emphasis on muscle tissue, gills, internal organs, the oral cavity, with microscopy of the contents of the gall and bladder. Data from parasitological studies of Kutum in the river. Terek, Sulak, Samur, Aksai, Kuma were subjected to statistical processing using the Biometrics computer program. At Kutum at the river basin of Terek, in Dagestan were identified 25 species of parasites. At river Sulak - 25 species, at the river Samur - 24, at the river Aksai - 23 species, at the river Kuma - 24 species, everywhere with indicators of weak, medium and high level of invasion.. In the rivers of the Kutum regione, the representatives were of the genus Myxobolus, having the highest biodiversity of parasites - 7 species (Myxobolus kubanicus, Myxobolus ellipsoides, Myxobolus dogieli, Myxosoma bran-chialis, Myxobolus dispar, Myxobolus dameudorus pseudorus Dameudorus pseudodus Dameudodomus Dameudodus nobilie, Dactylorus aristichthys, Dactylorus ctenopharyngodonis, Dactylorus vastulae) and the less diverse species of the genus Trichodina - 2 species (Trichodina nigra, Trichodina reticulata), the genus Trichodinella - 2 species (Trichodinella bulbosa, Trichodinella epizootica). All species recorded, all season.
