Feed additives are gaining popularity as dietary supplements with the potential to support growth, immune competence, and the general health of aquaculture species.

Fish were fed six experimental diets: control (no additives), SSF (0.025% & 0.05%), MOS (0.1% & 0.2%), and combined SSF (0.025%) + MOS (0.05%).
