抄録

This paper presents the measuring weight error of fish body based on drainage time, mechanism of the weighing box, and the relationship between the error of the body width selected and counting error. <br>1. When the drainage time of fish body discharged from the separating mechanism is 10s, the measuring weight error is small and constant.<br>2. If the dividing clearance of the weighing box is wider than the body width and smaller than the body length, it prevents the fish from learing out of the weighing box.<br>3. If the ratio of the largest body width to the smallest body width is small, the counting error is small.<br>4. When the number oftish inside the weighing box is 20 fry and the velocity of the weighing conveyor is 0.2m/s, the counting capacity of the system is 144, 000 fry per hour.
