Abstract: The invention provides a method of preparing pelletized aquaculture feed for administration to farmed aquatic animals. The method may include the steps of causing water to circulate in a loop conduit, introducing aquaculture feed pellets into the water circulating in the loop conduit whereby to expose the pellets to pressure changes and thereby cause the pellets to become water-impregnated, and retrieving the water-impregnated aquaculture feed pellets from the loop conduit.
Abstract: The invention provides a method of producing an aquaculture feed composition which method comprises causing water, optionally together with a lipid, to be taken up by protein-containing feed pellets, characterised in that said pellets contain as a binder a plant seed flour.
