Patent ID: 8865197

Claim:
A food formulation for aquatic animals comprising: (a) at least one encapsulated nutritional substance; (b) an encapsulated digestion enhancing composition effective to trigger enhancement of at least one digestive process in the aquatic animal, wherein said nutritional substance and said digestion enhancing composition are encapsulated in at least one protective layer so as to protect said nutritional substance and said digestion enhancing composition until said nutritional substance and said digestion enhancing composition reach a designated area of the digestive tract of the aquatic animal, said digestion enhancing composition and said at least one nutritional substance then being released and said digestion enhancing composition thereby enhancing absorption of said at least one nutritional substance; (c) a sticky coating of charged lipids said sticky coating is encapsulated by said at least one protective layer, said sticky coating is associated with at least part of quantity of bioactive agent other than said nutritional substance and said digestion enhancing composition, said sticky coating being configured such that, when exposed, said sticky coating tends to adhere to an internal surface of the digestive tract, thereby localizing release of said at least part of said quantity of bioactive agent; (d) a delay layer encapsulating said sticky coating, said delay layer being configured to delay exposure of said sticky coating after breaching of said protective layer such that said at least one nutritional substance is released prior to exposure of said sticky layer; (e) an outer protective layer, wherein said outer protective layer is external to said protective layer; and (f) at least one buoyancy modifying particle confined by said protective layer, said buoyancy modifying particle being chosen such that said food formulation exhibits neutral buoyancy such that said food formulation remains suspended in water.
