  The supersymmetric product of a supercurve is constructed with the aid of a
theorem of algebraic invariants and the notion of positive relative
superdivisor (supervortex) is introduced. A supercurve of positive
superdivisors of degree 1 (supervortices of vortex number 1) of the original
supercurve is constructed as its supercurve of conjugate fermions, as well as
the supervariety of relative positive superdivisors of degre p (supervortices
of vortex number p.) A universal superdivisor is defined and it is proved that
every positive relative superdivisor can be obtained in a unique way as a
pull-back of the universal superdivisor. The case of SUSY-curves is discussed.
