In the present study, bio-automatic feeder system is developed in the consideration of physicochemical characteristics of assorted diet. Efficiency of the system includes prevention against natural deterioration of the diet by over heat in summer and improvement of food efficiency by controlling scattering characteristics and feeding amount etc. If the system introduced to marine net cage, retrenchment of feed expenses and reduction of environmental risk could be anticipated. The results of efficiency test represented like below: The bio-automatic feeder was comprised of 4 elements: hopper, volume controller, scatterer and main controller. Considering the high temperature and humidity in summer, hopper designed to prevent feed from deterioration as dual structure using natural convection current in the hopper system. For the scatter, scattering distance was increased over the increase of the rate of rotation. Optimal rotation rate was estimated by 350 rpm where exhibit the 2.5 - 3.5 m in maximum scattering distance, 2 m in mode of scattering distance and 1.4-1.8 m in maximum scattering width. The volume controller, a feed supplier from hopper to scatterer, is designed to control the feed volume by rotary rotor with a length-variable rectangular hole. The capacity is assumed to 9.5 - 28 g/min. for the diet of ø 1 - 7 mm.
