The bisan-seto sea area is not only an important marine transportation hub but also a good fishing ground. The stownet fishery is operated energetically in the bisan-seto sea area. Its main fishing grounds conflict with legal traffic routes. Ship's operators and fishermen have discussed this conflict problem, still they don't have sufficient solution yet. It is necessary for sufficient solution of this conflict problem to approach this problem by a new investigation method. In this study, we have researched their conflict condition. And also, we have examined evaluating the difficulty of ship-handling by avoiding stownet fishing boats and the difficulty of operating stownet fishery in the legal traffic routes through the environmental stress model. Then, we have discussed possibility of evaluating them by the environmental stress model.
