Abstract：We generalize the fermionic quantum fluid approach for S=1/2 spins to arbitrary spins. Within a mean field theory we find several

plausible spin liquid states for S=1 antiferromagnets on triangular lattices. A phase diagram for the J_1-J_3-K model is constructed and

the applications to recently discovered material NiGa_2S_4 are discussed.
