چکیده
The use of an automated net-hauling system using four polyethylene (PE) pipes is proposed in this study to increase the efficiency set net fishery. In system, are installed on seabed beneath a box chamber net. Compressed air injected into first pipe at slope and then other succession. fish cornered between fourth end performance from second evaluated numerical analysis, water tank tests, field experiments. addition, static model for deformation PE developed theory finite validated by results coastal sea show that maximal bending stress full-scale about 10 MPa, which within allowable range 23 indicating risk breakage considerably low. Therefore, has high application value development potential
