The Yangtze River is an important strategic water source, ecological treasure trove and golden waterway for China, and an important support for the sustainable development of the Chinese nation. There are more than 4,300 species of aquatic organisms in the Yangtze River basin, including more than 400 species of fish (including subspecies), including more than 180 species of fish endemic to the Yangtze River, making it one of the richest rivers in the world in terms of aquatic life. However, in recent years, due to over-fishing and other reasons, the ecological environment of the Yangtze River waters has suffered serious damage, the biodiversity index has continued to decline, and the resources of rare and endemic species are in rapid decline.
In August 2020, General Secretary Xi Jinping pointed out at the symposium on promoting the integrated development of the Yangtze River Delta that the ban on fishing in the Yangtze River is an important decision for the overall situation and for future generations. A press conference was held on the situation. The conference indicated that the initial results of China's ten-year fishing ban have emerged, mainly in the following three aspects: the resettlement of retiring fishermen is basically in place, the order of the fishing ban in key waters is generally stable, the aquatic biodiversity of the Yangtze River has gradually recovered, and the number of finless porpoises has steadily rebounded to 1,249.
The results are remarkable, but we still can not let down our guard, because the Yangtze River '10-year ban' is a protracted war, long-term, arduous, complex coexist, need to work for a long time, sustained efforts. According to the relevant person in charge of the Yangtze River Fishing Ban and Retreat Leading Group Office, under the trend of continuous high pressure crackdown, new situations and changes have emerged in illegal fishing: firstly, diving fishing and other methods are used, and the means of operation are more hidden; secondly, unmanned boats and other high-tech tools are used; thirdly, the illegal fishing waters have shifted from the Yangtze River and Jialing River and other main streams to the remote waters of small tributaries, which makes the work of fishing ban more difficult and brings The challenge of the ban on fishing has increased.
The most effective measure is to strengthen the enforcement and supervision of the ban on fishing, and to continuously strengthen law enforcement, justice and law-abiding work to ensure that the shield of the rule of law defends the home of fish life and guards the Yangtze River with the rule of law.
Traditional human patrols possess problems such as difficulty in obtaining evidence, high cost and long time. The illegal fishing behavior generally occurs at night, and once the offenders find the law enforcement vessels and law enforcement officers, they immediately flee in terms of passive evidence collection, which largely hinders law enforcement activities. In addition, inspection takes a long time. A traditional 80km stretch of river would take 2-3 days to complete with 2 inspectors, which is inefficient. The labor cost is too high as several people have to be deployed for each inspection.
The use of drones has effectively made up for the lack of human resources in fisheries law enforcement work. It can not only patrol and conduct surprise inspections of waters from the air, improving coverage and inspection efficiency, but also provide a comprehensive and close observation of waters that are beyond the view and vision of law enforcement officers, helping them to have a clearer grasp of the situation on the water. In addition, the flexibility of drones can also be used to conduct high-definition camera evidence on illegal electrofishing vessels in no-fishing zones, improving enforcement efficiency and avoiding aimless inspections by law enforcement officers.
With the further development of drone technology, drone inspection is also moving towards intelligent and integrated automatic inspection. The Digital Eagle UAV nest empowers all types of industrial drones to carry out automatic patrols of rivers, reservoirs and lakes, increasing efficiency by more than 10 times compared to traditional manual patrols. No need for professional pilots to control the drones, one key setting in the background, automatic take-off and landing, automatic patrol; automatic charging of the drones, for long-duration tasks to escort; rich API interface, can simultaneously access a variety of business identification systems, such as: floating objects, illegal violations, illegal fishing, illegal sewage, etc., to help the construction of intelligent water conservancy.
From drones to nests and then to cloud management platforms all at once, Digital Eagle portrays a complete and highly compatible solution for the industry, focusing on all aspects of the application scenario, forming a fusion of hardware and software innovation, allowing the popularity of automated drone operations applications to begin to show the trend of large-scale landing.
