Description of a modular, low cost, eater meter for the study of feeding behavior and food preferences in fish.
The eater meter described in this paper is especially designed for fish studies. It consists of three parts: the detector, the feeder, and the interface between the detector and the feeder. The detector is a rod that closed a circuit (by contact or through a magnetic detector) when stuck by a fish, the feeder is electric and can be of any commercial model, and the interface is a simple electronic device, or a computer. Some preliminary results obtained with rainbow trout, Oncorhynchus mykiss, are also presented in order to illustrate the uses of this modular eater meter for fish.
