This research proposed  ?alternatives to solve the problem focusing on the idea of line balancing by reorganizing the plant layout and machine implementation for increasing efficiency of tuna conveying system as follows: ?apply diverging belt and reorganize the plant layout of the production line for rapidly grading variety sizes of fishes JO?B?MBSHF?BNPVOU??apply conveyor belt equipped with arranging rollers into the production line without reorganizing the plant MBZPVU? ?apply conveyor belt equipped with arranging rollers into the production line and reoSHBOJ[F?
