ABSTRACT

The conceptual approaches for investigation of dynamics of populations in a system "parasite - host" under conditions of toxically contaminated aquatic environment are considered. Taking into account those concepts and some possible modes of interrelations between parasites, their eggs and populations of hosts, the mathematical models for a "parasite - host" system have been constructed. These models quantitatively characterize with a various plentitude the components of such a system. In particular, the results of calculations are shown pertinent to the dynamics of parasite and host populations at an intense host reproduction, and also in the case when host population is degraded (mortality prevails over the birth rate.)
