机帆船大围缯是我市主要捕捞作业,由于黄鱼、带鱼等主要经济鱼类资源严重衰退,直接影响到我市捕捞生产的发展。为了开发利用经济价值高的大中型虾类,近年来,我们把捕虾作为海洋捕捞的重点来抓,通过引进消化,研制多种不同规格的对虾三重流刺网,在渔区进行多点捕虾试验,筛选出一种与本市现有渔船设备、渔场条件、捕捞对象相适应的对虾三重流刺网,取得较好的经济效益和社会效益。1988年共发展对虾三重流刺网483个单位,产量28.66吨,产值276.98万元,为我省对虾人工育苗提供了5317尾成熟的亲虾,降低了虾苗成本,促进了对虾人工养殖的发展。现将对虾三重流刺网捕捞技术介绍如下:
Large yacht sailing is a major fishing operations in our city, due to the serious economic decline of the main economic fish such as yellow croaker, octopus, directly affect the development of fishing production in our city. In order to develop and utilize large and medium-sized shrimp with high economic value, in recent years, we regard shrimp catching as the focus of marine fishing. By introducing and digesting, we have developed a series of multi-punctured shrimp nets with different specifications, Shrimp test to screen out a tricolored shrimp net suitable for the existing fishing vessel equipment, fishery conditions and fishing targets of the city, and achieve better economic and social benefits. In 1988, a total of 483 units of shrimp triple streamers were developed with a production of 28.66 tons and a production value of 2.7698 million yuan, providing 5317 mature broodstock for artificial breeding of shrimp in our province, reducing the cost of shrimp cultivation and promoting the development of artificial breeding of shrimp . Triple prawn net fishing technology now introduced as follows:
