Aquaculture feeding monitor

摘要

The invention is a system (10) for measuring the rate of food pellet loss in a fish farming operation. The fish are held in a seacage (14) in a bottom of water. Food dropped into the seacage (14) sinks down through the cage and uneaten pellets exit the bottom of the seacage (14). An echo transducer (12) below the cage generates an echo pattern that is converted into pellet loss data.
