The study was undertaken utilizing only an engine tachometer and an oil pressure gauge of a prototype Peruvian small purse seiner. The empirical relationships between a velocity of a winch (Vw; m/s) and an enging revolution (Ne; rpm), and between an effective force of a winch (Fw; kgw) and an effective output pressure of an oil pump (P-Po; kgw/cm2) were determined based on the equations obtained by the previous study. Assuming the loaded pressure (P; kgw/cm2) and the non-loaded pressure (Po; kgw/cm2) of the pump, since Po=19.7kg/cm2, then Vw=0.000415Ne and Fw=24.5 (P-19.7) Moreover, in standard fishing operations of Peruvian small purse seiners, Vw=0.52m/s and Fw=367kgw could be practically determined. These values could be used to examine the mechanical properties of a fishing gear during fishing operation.
