Abstract: A food dispenser (10) with particular application to delivering a controlled amount of food material (11) in particulate or powdered form to fish and other aquatic animals, and also a method of delivery of such material. The food dispenser comprises a receptacle (12) for holding the food material and shutter means (14) located at a lower end of the receptacle. In its open position, the shutter provides a passageway (16) from the receptacle past the shutter for delivery of the food material. A dispersing unit (50) supplies an air flow for dispersing the food material. A flexible mounting bracket (60) enables vibration of the dispenser during operation to assist the flow of the food material.
