Small trawl fishing is an important fishery that supplies a variety of fishery products to the market. The fishing operations are usually carried out in coastal seas. In this study, the authors focused on beam-type small trawl fishing boats in the northern coastal seas of Kyushu. And we conducted a survey about the operating methods and the labor-saving effects by use of fishery machines. By the use of the trawl winch, the shooting net time was shortened compared to the conventional method. Furthermore, applying the OWAS method for the physical burden of skipper, the labor-saving effects are confirmed on net shooting and hauling operations.
