Abstract: If the cubic surface over finite field is minimal then the image of the Galois group of algebraic closure in the Weil group is conjugate to one of five cyclic subgroups of orders $3$, $6$, $6$, $9$, $12$. For each of these subgroups we construct explicit examples of minimal cubic surface with little restrictions on the number of elements in the field.
