At about 8 p.m. on July 28, an illegal fisherman groped toward the shore in the darkness of night in the grass by Wuhu Lake in Huangpi District, Wuhan. Although it was dark at the scene, the yellow patches in the infrared thermal imaging system had pinpointed the offenders. From 00:00 on July 1 this year, a 10-year ban on fishing has been formally implemented in the sections from xinhekou to Juishui river in Xinzhou District, Wuhan Economic and Technological Development Zone (Hannan District) in the Yangtze River Basin, Wuhan, and from Xiebajia in Caidian District, Hanjiang to Nanjianzui River in Hanyang District. Wuhan police introduced a variety of high-tech equipment, including infrared thermal imaging and automatic inspection drones. They also built a big data platform with agriculture, rural affairs (fishery administration), market supervision and other departments to strengthen coordination and linkage, improve the reflex nerve of fighting against illegal fishing, and use a variety of smart weapons to protect the Yangtze River.

The use of infrared thermal imaging technology can clearly identify illegal fishermen and locate their movement tracks. The introduction of this technology has enabled the police to have "night vision devices", making illegal fishing no longer invisible at night, changjiang Daily reports from the Wuhan police. On the information platform for cracking down on illegal fishing crime, more than 20 pieces of information such as fishermen, fishing boats, catering establishments and fishing-related police situation can be learned in Wuhan. In addition, video surveillance images of all waters of wuhan can be real-time reviewed and early warning can be made. All data can be integrated and a channel for command circulation and feedback can be established. The data platform can realize the linkage of multiple departments more quickly and better, and realize the long-term mechanism of combating illegal fishing, which is "all-round data aggregation, dynamic perception of the whole river basin, dynamic control and control of total factors, full-dimensional intelligent early warning, and whole-closed-loop linkage processing".
