[RESULTS OF THE STUDY OF GEOGRAPHICAL VARIABILITY OF THE PARASITE FAUNA AND OF THE STRUCTURE OF COMPONENT COMMUNITIES OF MINNOW PHOXINUS PHOXINUS (LINNAEUS) PARASITES. 2. THE WATER BODIES OF THE NORTHEASTERN EUROPEAN RUSSIA].

The material was collected according to commonly accepted methods in 1992—2013 from the following sites: the Lake Krivoye (Kolguev Island); Volonga, Schapkina, Kolva, More-Yu, Vorkuta, Kara, and Khalmer-Yu Rivers; Lakes Nikaramata (the Kara River basin) and Mercempertato (Yamal Peninsula). A total of 436 of the minnow Phoxinus phoxinus with age 1+—3+ were examined. In the examined water bodies, excluding the Kolva River, the parasite fauna of the minnow is impoverished, and, to a greater extent, possesses an occasional character.

[PARASITE FAUNA AND STRUCTURE OF PARASITE COMPONENT COMMUNITIES IN THE MINNOW PHOXNUS PHOXINUS (LINNAEUS, 1758) IN AN OIL POLLUTED WATERSTREAM].

In June 1992 and July 1996, 238 minnow specimens of the 2+--3+ age were collected from 5 parts of the Kolva River and studied using the standard technique of the general parasitological dissection. Comparative analysis of parasite fauna and the structure of component parasite communities in the minnow from ecologically safe and variably polluted parts of the river was performed. The analysis had demonstrated that the increase in the water pollution by domestic wastewater, washings of fertilizers from agricultural fields and private country houses, cattle farm drains (Dorovskikh et al.

[Influence of the minnow Phoxinus phoxinus L. sex on the composition of the parasite fauna and component community structure of parasites].

225 minnow specimens of the 2(+)-3+ age were collected and studied using the standard technique of the total parasitological dissection. The component parasite community in a period of studies was well-established. This state is characterized by maximum species richness and biomass values.

During January May, 2007, 105 specimens of minnow of the 2+ -- 3+ age were col- lected from the Pechora River in the central homestead of the Pechora-Ilechsky Natural Reserve, and studied using the standard technique of the general parasitological dissection. It was concluded that in a period of studies the component parasite community was in a formation process.

[Results of the study of the geographical variability of the parasite fauna and of the structure of component communities of the minnow parasite Phoxinus phoxinus (L.) 1. Basins of the Kama and Northern Dvina Rivers].

In the basin of the Kama River, in upper Vychegda River, and in tributaries of the upper Northern Dvina River, the parasite fauna of the minnow is monotonous and component communities of parasites are mature (balanced, according to Pugachev, 1999). They are completely formed in June.
