Use of structure of multispecific association of helminths (MAH) of perch for ecological monitoring of water ecosistem

The results of long-term researches (1990-1992, 1996-1997, 2002, 2009) of multispecific association of helminths of perch of the Saratov reservoir are generalized. Transformations are exposed to the structure MAH of perch, kernels of multispecific association of helminths and order of their prevailing expressed in a change. It specifies on that the active process of change of food chains registers in ecosistem of the Saratov reservoir, which is conditioned including in them of foreign types of water organisms.
