Abstract：
The Indonesian fisheries management system is now equipped with the state-of-the-art technologies to deter and combat Illegal, Unreported and Unregulated (IUU) fishing. Since October 2014, non-cooperative fishing vessels can be detected from spaceborne Vessel Detection System (VDS) based on high resolution radar imagery, which directly benefits to coordinated patrol vessels in operation context. This study attempts to monitor the amount of illegal fishing in the Arafura Sea based on this new source of information. It is analyzed together with Vessel Monitoring System (VMS) and satellite-based Automatic Identification System (Sat-AIS) data, taking into account their own particularities. From October 2014 to March 2015, i.e. just after the establishment of a new moratorium by the Indonesian authorities, the estimated share of fishing vessels not carrying VMS, thus being illegal, ranges from 42 to 47%. One year later in January 2016, this proportion decreases and ranges from 32 to 42%.
摘要：
印度尼西亚的渔业管理系统现在配备了最先进的技术，以阻止和打击非法，未报告和无管制（IUU）捕捞。自2014年10月以来，可以根据高分辨率雷达图像从星载船舶检测系统（VDS）中检测到非合作渔船，这直接有利于协调巡逻船在操作环境中。本研究试图根据这一新的信息来源监测阿拉法拉海的非法捕捞量。与船舶监测系统（VMS）和基于卫星的自动识别系统（Sat-AIS）数据一起分析，考虑到自己的特殊性。从2014年10月至2015年3月，即在印度尼西亚当局制定新的暂停措施之后，不携带小型渔船的渔船的估计份额，因此是非法的，从42%到47%不等。一年后的2016年1月，这一比例下降，范围从32％到42％。
