                                Over 50% of the world's seafood is now produced through aquaculture, and the search for sustainable feed sources has become a major industry priority. A variety of fish species, both in captivity and in the wild, have been found to consume yeast, a single-celled eukaryote rich in protein, vitamins, and minerals. Incorporating yeast into the diets of fish is a practice used by both large-scale commercial fisheries and home aquarists to improve nutrition and boost disease resistance.
