A basic study on the improvement of the continuous type fishing system for largehead hairtail hand line in coastal area of Jeju island, Korea

Abstract

This experimental study was carried out to obtain the base data for saving the man power in the fishingoperation of largehead hairtail hand line by using the continuous type hand line system with a rotary devicewhich could make a main line move automatically. In order to solve the twists and entangling on the mainline happened during operating test, the resistance board was suspended at the end of the main line at sea. Asthe result, there were no problems of tangling and so on due to up and down moving of a main line.According to the control of a fixed angle of guide roller, it was possible to prevent the main line to beseparated from a side roller and a guide roller. In addition, PVC tube between a guide roller and a side rollerenabled a main line to be moved smoothly without any entanglement.Key words : Continuous type hand line, Side roller, Guide roller, Guide tube, Resistance board
