title: A microcomputer-controlled demand feeder for the study of feeding behavior in fish.
abstract: This paper describes an easy-to-make, low-cost demand feeder. The electromechanical design ensures a single-pellet delivery for each demand. The feeder, activated by a fish pressing a bar, is driven by a solenoid. A variety of pellet shapes and sizes can be used, offering broad experimental versatility. The feeder is also suitable for microcomputer control.
