The hydrodynamics of an arbitrary quantum fluid is considered. The complete set of Poisson brackets for quantities describing the state of a quantum fluid in the presence of vortices (solitons) is found by generalizing the relations for vortex-free motion. The hydrodynamic equations of motion are written down, as well as the ensuing conservation laws for the momentum energy and the quantities connected with the intrinsic symmetry group of the system. The degrees of freedom connected with the normal motion are taken into account. The hydrodynamics of superfluid He are considered as an example. The complete set of equations and the conservation laws for rotating He/sup 4/ are found. The anisotropic superfluid He/sup 3/-A is considered. The variables required for describing the hydrodynamic motion in the presence of continuously distributed solitons, the nondissipative hydrodynamics laws, and the conservation laws are presented.
