We study the consequences of the existence of spacelike Ricci inheritance vectors (SpRIVs) parallel to x<sup>a</sup> for a model of string cloud and string fluid stress tensor in the context of general relativity. Necessary and sufficient conditions are derived for a spacetime with a model of string cloud and string fluid stress tensor to admit a SpRIV, and a SpRIV which is also a spacelike conformal Killing vector. Also, some results are obtained.
