Effects of Inertial Mass Coefficient on Knotless Netting Model Used in Tuna Purse Seine

This paper aimed to research the effects of inertial mass coefficient on knotless netting models used in tuna purse seine. Knotless nettings were modeled and simulated using mathematical and mechanical models. In the simulation, the marine environment was imitated in the computer. The results demonstrated that inertial mass coefficient was a key factor to affect the stability of knotless model, especially in the sinking process, and the model presented more stable and quicker convergent as the inertial mass coefficient increased. During fishing operation at sea, the instability of the sinking of purse seine with knotless nettings, especially in the area with complicated currents and waves, might be due to the smaller inertial mass coefficient of knotless nettings.
