本文通过对三种材质的同档次拖网渔船的经济效益和社会效益调查、从维修费、折旧费、燃油、冰、捕捞产量和产值、节能诸方面进行了比较分析、认为玻璃钢拖网渔船的经济效益和社会效益明显优于同类型钢质或木质拖网渔船。因此、大力推广玻璃钢渔船具有重大的现实意义。尤其是在节能方面、钢质、木质拖网渔船与其是无法比拟的。
Based on the investigation of the economic benefits and social benefits of the three types of trawlers with the same grade, the paper analyzes the maintenance costs, depreciation expenses, fuel oil, ice, fishing output, output value and energy saving. It considers that the economic benefits of FRP trawlers And social benefits are obviously better than the same type of steel or wood trawlers. Therefore, it is of great practical significance to vigorously promote FRP fishing vessels. Especially in terms of energy saving, steel trawlers are incomparable with wood trawlers.
