Abstract: A feeding system for cultured species including: (a) providing (i) a sensor able to detect feed particles passing through a sample area, and (ii) a control unit, including computer data storage age media in communication with the sensor, and (b) detecting and discriminating feed particles that pass through the sample area; wherein the control unit is able to process information obtained from the sensor and regulate subsequent feed output based on algorithm parameters, said algorithm parameters determine the instantaneous feed rate of the cultured species to adjust and match the preferred feed values meted to the cultured species at any given time.
