Abstract
The acoustic target strength of caged Atlantic mackerel (Scomber scomb rus) increased considerably after feeding on commercial dry pellets. T he result illustrates the potential use of hydroacoustics for in situ measurement of food consumption in fish without swimbladders. In this pilot study, hydroacoustic observations of food intake and food-waste eaters confirmed visual observations of a shift in feeding behaviour a ccording to type of pellet.
