摘    要:本文反映四片式双桩张网的试验结果。张网是我国主要定置渔具,但旧式张网结构工艺繁琐,网型不合理,渔捞性能差,并破坏经济鱼类资源。作者针对存在的上述种种弊端并结合网具硫目趋向而设计和试验,采用大目双桩张网。根据模型试验和生产对比试验,它比旧式张网滤水性能好,网具阻力小,渔获效率高。一般,比原生产网降低成本10%以上,提高产量5~30%。这也就适应了我国机械编网的总趋势。目前该项成果已在山东沿海推广。

关 键 词:双桩张网  剪裁  渔获性能  鱼类资源

Abstract:Stow net, an important type of stationary fishing gear in ma-rine fishery, contributes to approximately 30 percent of marine catches in China.Conventional form of this stow net, braided manually and sophisticatedly, withimproper net form and small mesh size, showed poor catehability and seriousdamage to fish resources. In order to change the situation, after investigation onstow net in China from 1989 to 1990, a new type of stow net with four panel anddouble stake in structure was designed and tested. Comparison experiment showedthat the new net could reduce cost by 10 percent and increase yield by 5 to 30percent. The experimental success of the net technologically completed the impor-tant transfermation of weaving way, from manual creasing and shrinking tocutting, especially to mechanize braiding. With improved catchability and stableincrement of yield and income, as to the conventional net, the new one is verypopular with fishermen, it has been put into widespread usage, getting desirableeconomical benefits.
Keywords:stow net with double stake  cutting  catchability  fish rasources
