The aquaculturist is faced with a number of difficulties when feeding fish. Apart from the human time component involved in feeding a large number of fish to appetite, it is important to feed an appropriate quantity at a suitable frequency to ensure that no food is wasted and fish are satiated. Fish display preferential feeding patterns that relate to endogenous rhythms and changing biological and environmental factors. This study describes a new technology called the \Adaptive\" Feeding System designed to automatically feed fish by regulating feed input based on the levels of waste food detected beneath a feeding zone. A series of trials with the system are also discussed. The system consisted of a surface mounted microprocessor linked to an underwater sensing device capable of resolving a single feed pellet. An internal algorithm controlled the operation of the system. Feeding data was stored by the microprocessor and down loaded via a data-logger to an IBM-compatible computer for analysis with specific ...
