【摘要】 根据1999~2000年对我省四艘灯光围网试验船进行光源配置方式的重大改革,即改革传统的灯艇水下光源配置方式,将主光源直接配置在母船驾驶台左右舷上。结果表明新的光源配置方式可有效地解决原作业方式光源强度严重不足这一瓶颈,光源强度比原作业方式提高11.7~15.2倍,从而大幅度地扩大诱集水域;经试验船711网次和对比船839网次的试捕生产,试验船平均网次产量比对比船提高73.6%;技改后劳动力配置由原来每艘43~45人减少至18~23人,平均每艘船每年可降低生产成本18.4万元。实践证明,光源配置方式的改革可有效地提高灯围产量、降低生产成本、减轻劳动强度、增加渔民收入。更多还原

【Abstract】 According to significant innovation of the light-source fittings mode on four light seine test vessels during 1999 to 2000, we change the traditional underwater light-source fittings of light boat and directly fixe the light-source on larboard and starboard of driving seat. The results showed that the new mode can effectively settle the insufficiency of light intensity of the former mode, the light intensity is 11.7 to 15.2 times higher than former mode and greatly enlarge effecting waters. Based on testing by 711 nets of test-boat and 839 nets of comparison-boat, the CPUE of test-boat is 73.6% higher than that of comparison-boat, fisherman numbers reduce from 43～45 to 18～23, and one vessel may reduce productive cost 184 thousand Yuan in a year. Thus, the reform of light-source fittings mode can effectively increase the yield of light seine, reduce production cost, abate work intensity and increase fishermen’s earning.更多还原
