FISH FEEDING CONTROL IN AQUACULTURE ON THE BASIS OF SOUND EMITTED BY FISH

摘要

The present invention, relates to an electronic processor-based system for fish farming plants. The system receives the overall sound that is generated by fish in the defined cage or pond at the feeding time interval (16 and 17). On the basis of this data, the system calculates the dynamics of fish activity during feeding and generates a prediction of when to add a feed (13). In addition, the biomass of fish can be calculated from the sound data. Fish sound is a function of fish biomass. In this way feeding can be accurately adjusted to the population growth of the fish. Accurate knowledge of the fish biomass provides a method of indication the presence of disease (decreased biomass), enabling quick preventative action. Furthermore, knowledge of fish biomass can indicate theft or the presence of fish predators.
