A new device for recording the feeding activity of milkfish

Abstract

Knowledge on the feeding activity is basic and very important for rearing fish. The information on the feeding activity rhythm of the animal suggests the proper time to feed it. Many devices have been designed to record the feeding activities of aquatic animals. Some are mechanical devices which are difficult to maintain in good conditions for a long time. None of the present devices can be applied to milk-fish because of its characteristic manner of taking food. In this paper, a new electrical device for recording the feeding activity of milkfish is reported.
