Abstract
A feed comprising a culture product of strains of marine or halophilic yeasts in which the COD rising index of the strain is not more than 150 and the RNA excretion rate is not more than 20% in a medium containing waste molasses and an inorganic nitrogen compound, and a method for cultivating aquianimals with the feed. Typical example of the yeasts is Torulopsis candida var. marina NRRL Y-7345. The feed is particularly useful for breeding, for example, Brachionus, Copepoda, Brine Shrimp and Stage of Zoea, Mysis and Post Larva of shrimps.
