Thematic Map Service of the Tuna Purse Seine Fishery in the Western and Central Pacific

中西太平洋渔场是世界金枪鱼捕捞产量最高的渔场之一,由于金枪鱼属于中上层高度洄游鱼类,渔场变动较大,借助遥感产品辅助渔场中心判断是一种有效的手段。上海开创远洋渔业有限公司金枪鱼围网主要集中在中西太平洋,生产过程中利用海表温度、叶绿素、海面流场等海况产品辅助捕捞决策。文章基于地理信息和遥感技术,开发了后台数据自动处理软件,完成数据获取、解码、投影转换、专题图制图等流程,完成渔场专题图自动制图,并通过微信、FTP和网站提供服务,可以很好的为渔业分析与管理。

The central and Western Pacific fishing ground is one of the highest tuna production fisheries in the world.Because tuna is a highly migratory fish in the middle and upper layers,and the fishing ground changes greatly,it is an effective method to use remote sensing products to assist the judgment of fishing center.Tuna purse seine of Shanghai KaiChuang Deep Sea Fisheries Co.,Ltd is mainly concentrated in the central and Western Pacific Ocean.In the production process,sea surface temperature,chlorophyll,sea surface current and other sea state products are used to assist fishing decision-making.This paper is based on geographic information and remote sensing technology.Through programming,the data download,decompression,cutting,projection,numerical calculation,grading color setting and other processes are realized.Complete the automatic mapping of fishery thematic map.Through Weixin,FTP and website services,it can be very good for fisheries analysis and management.
