In this paper, we define fuzzy subnexuses over a nexus $N$. Define and study the notions of the prime fuzzy subnexuses and the fractions induced by them. Finally, we show that if S is a meet closed subset of the set Fsub(N), of fuzzy subnexuses of a nexus N, and h= ⋀S ϵ S, then the fractions S^-1 N and h^-1 N are isomorphic as meet-semilattices.
