Lie and conditional symmetries of the classical Lotka-Volterra sys- tem inthe case of one space variable are completely described and sets of suchsymmetries in explicit form are constructed. These symmetries are used toreduce the classical Lotka-Volterra systems with correctly- specifiedcoefficients to ODE systems and examples of exact solutions in explicitform are found. The properties of the obtained solutions are examined withthe aim to provide the relevant interpretation for population dynamics.
