The present disclosure relates, according to some embodiments, to methods for recovering multiple products from industrial-scale production of a biomass of an aquatic species. Specifically, the present disclosure relates, in some embodiments, to methods for cultivating Lemna for extracting a protein concentrate, a biocrude, and/or a carbohydrate-rich meal. In some embodiments, a process of recovering at least one product from biomass of an aquatic species may comprise: lysing a biomass to generate a lysed biomass; separating the lysed biomass to generate a juice and a first solid phase; filtering the juice to generate a filtered juice and a second solid phase; clarifying at least one juice to generate a clarified juice and a third solid phase, wherein the clarified juice comprises a soluble protein; coagulating the soluble protein from the clarified juice to generate a liquor comprising a wet protein concentrate; and separating the wet protein concentrate from the liquor.
