灯光围网母船光源配置技术及其效果分析

The Light-source Fitting Technology and Effect Analysis of Mother-ship of Light Seine Net

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.

Breeding in outer space, which has made significant achievements but limited to crops seeds and strains, is one of the most important projects in the global competition for exploitation of outer space. Due to the special requirements for satellites and living conditions for aquatic organisms, no fishery live - baits have been set to outer space for breeding purpose by now. This article will begin the exploration on this subject on basis of experiments.
