An anti-strange quark is an antiquark corresponding to the strange quark.
It depends on the exact antiparticle you are talking about. When a particle has an electric charge, its antiparticle would have an equal, but opposite charge. For example, protons have a charge of +1, while antiprotons have a charge of -1. This applies to all electrically charged particles, including quarks (particles that make up hadrons) When a particle is a hadron (composite particle), then usually the quarks inside them are antiquarks. For example, the quark structure of a neutron is udd (up up down) while the quark structure of an antineutron is antiup, antidown, antidown. The charges cancel each other out, and antineutrons are left with no charge, just like neutrons. If the particle had charge, then the combination of charges of its antiparticle's quarks would be equal, but of opposite. In addition, some other properties are also the same, but opposite, Some particles (eg. photons, Z bosons) are their own antiparticles.
