A method of bioprocessing using a liquid biofeed is provided. The method includes the steps of floating a container comprising a first bioprocessing organism on a pond; and placing a liquid biofeed within the container, whereby the first bioprocessing organism consumes a substance within the liquid biofeed, to thereby bioprocess using the liquid biofeed. The pond may comprise an additional bioprocessing organism. The method may include the further step of transferring the liquid biofeed between the container and the pond before and/or after bioprocessing by the first bioprocessing organism, whereby the additional bioprocessing organism consumes a substance within the liquid biofeed. An apparatus and a system suitable for use according to the bioprocessing method are also provided.
