  • Title: [Methods for studying the distribution of Monogenea in the gills of fishes].
    Author: Gerasev PI, Starovoĭtov VK.
    Journal: Parazitologiia; 1994; 28(4):303-8. PubMed ID: 7816512.
    Abstract:
    The infection rate with monogeneans of different sites of fish gills was examined. The comparative analysis of average parts (in %) was made after [see text] Fisher where phi is a percentage in radians, n -- the number of fishes dissected, v -- degrees of freedom. It was shown statistically, that part (%) of dactylogyrids on II paris of the gills is significantly greater than parts from I and III pairs of the gills. The parts of the parasites were not distinguished on I and III pairs of the gills. The part of worms on IV pair of the gills is the least. It was shown that statistically significant part of the dactylogyrids was observed in the middle sector of the gills. Factors, which could led to unequal distribution of monogeneans on the gills, are discussed. The main factor appears to be a volume of water stream passing through different pairs of the gills.
