Conserved Quantities in Wave Turbulence and their Cascadestions for presenceof extra invariants are derived. Relations between the statistical and the dynamicalinvariants are discussed. Directions of the turbulent cascades in the k-space are found viaa generalised Fjørtoft’s argument (originally used in 2D hydrodynamic turbulence). ThePetviashvilli drift-w
