| Research Abstract |
A new net-hauling system in set net fishery was proposed in the present study. The net-hauling system is carried out by injection and ejection of air into a hose net, which is made in a brick form by flexible hoses. The hydrodynamic and mooring forces on the hose net were examined by water tank testing and numerical analysis. As a result, the hose net floated like an S shape to corner the fish. The tension of the hose net was at the maximum when half of the hose net was filled with air, and was two times the mooring force as a result of numerical analysis.
