Shanghai was rated as "excellent", and six national ministries assessed the ban and withdrawal of fishing in the Yangtze River Basin. Rural | Yangtze | Shanghai

The third meeting of the Standing Committee of the 16th Municipal People's Congress reviewed the report on implementing the Yangtze River protection and promoting the ten-year fishing ban on the Yangtze River today.

According to statistics, since the implementation of the ten-year fishing ban in the Yangtze River, the city has investigated and dealt with a total of 1484 cases of illegal fishing, transportation, and trading of wild fish in the Yangtze River, involving 1827 people; More than 4000 illegal nets have been cleared, and 166 "three no" ships have been cleared and banned; Inspect 427300 business entities such as markets, supermarkets, and catering, and monitor 3.2515 million e-commerce platforms. Last year, in the assessment of key water areas in the Yangtze River Basin by six national ministries, Shanghai was rated as "excellent" in the comprehensive assessment.

Supervision and research have found that since the implementation of the fishing ban, agricultural and rural departments and various scientific research institutions have strengthened the monitoring and protection of aquatic organisms, cracked down on illegal fishing, and strengthened the coordinated promotion of protection and restoration. As a result, aquatic biological resources and diversity have shown a positive trend of recovery. According to monitoring by relevant scientific research institutions, in 2022, 45 species of fish were detected in the Yangtze River Estuary, an increase of 7 species compared to 2021. The number of Yangtze River finless porpoises monitored has reached 13 times, and in April of this year, a newly born young porpoise was also detected. The average resource density of plankton, juvenile fish, and fish eggs in the Yangtze River Estuary has significantly increased compared to the previous year, with an increase of 300% to 550%. Taking the common concern of the public for the coilia, the single net fishing volume has increased by 113.6% compared to before the fishing ban. The average increase in biological characteristics data of fish such as total length, body length, and weight is 5.3%, 7.0%, and 35.0%, respectively.

The enforcement capacity of the Yangtze River fishing ban has also significantly improved. For example, the completion of the construction of the Changxing Island official base dock solved the difficulty of not having a dedicated dock. Two high-speed fishery law enforcement boats were delivered and put into service, with a maximum speed of 43 knots, effectively solving the problem of slow speed of law enforcement boats. The "four platforms" for the Yangtze River fishing ban have been completed and put into operation. The Municipal Agriculture and Rural Affairs Commission has integrated three platforms: ship registration information, dynamic supervision of fishing vessels, and law enforcement information. It has taken the lead in building an intelligent control system for the Yangtze River fishing ban in China, implementing all-weather and all water intelligent monitoring of the 3200 square kilometers of the Yangtze River Estuary fishing ban management area, and realizing the digital transformation of water law enforcement.

Although the Yangtze River fishing ban in this city has achieved phased results, it was found through supervision and research that there are still some problems and shortcomings. Since the implementation of the fishing ban, although the recovery trend of aquatic biological resources in the Yangtze River Estuary has improved and the integrity index of aquatic organisms has improved, it has not yet been fundamentally improved. The biological integrity index is low. Monitoring shows that the natural population size is still relatively small, and although the fish biodiversity index has increased by two levels compared to before the fishing ban, it is still in the fourth level of "poor" among the six levels. The endangered situation of rare species is severe. Especially for species with longer reproductive cycles such as Chinese sturgeon and Yangtze sturgeon, the restoration of germplasm resources is difficult, and their natural reproductive behavior has not been monitored for many years, posing a risk of regional disappearance; Although the number of Yangtze finless porpoises has increased, the overall population is still relatively small.

At the same time, the management of fishing bans at the mouth of the Yangtze River is facing new situations and problems. Research has found that after the fishing ban, the "four cleans and four no" measures in the Shanghai section of the Yangtze River have had a significant effect, but there have also been some new situations, such as the increasingly covert behavior of illegal fishing. Although the law enforcement continues to be high-pressure, driven by interests, some illegal fishermen engage in crimes against the wind, gradually changing fishing time points, using night cover, fighting time differences, and wandering back and forth in the inter provincial border waters, waiting for opportunities to catch fish. Some people break through the boundary of one person, one rod for recreational fishing and use one person, multiple rods, and multiple hooks on the line for illegal fishing. The last mile of the Yangtze River fishing ban regulation is facing challenges. The law enforcement in some areas is difficult. The Jiuduansha Wetland is covered with tidal ditches and reeds, making it suitable for ships to hide and illegal fishing gear difficult to detect. Due to the numerous shallow shoals in the Dongtan Reservoir area, law enforcement vessels are unable to enter, making it extremely difficult to clear the nets, which has a certain impact on the timeliness and accuracy of law enforcement inspections.

In addition, although our city has taken the lead in building an intelligent control system for the Yangtze River fishing ban nationwide, achieving digital and intelligent supervision, there is still significant room for improvement in interconnectivity, sharing, and sharing. The degree of inter provincial interconnectivity is low. The anti fishing platforms of each province and city are relatively independent, developed in accordance with the actual needs of their own anti fishing work. The interconnection and business collaboration of information resources between provinces are insufficient, and the intelligent sharing and sharing are still at a relatively low level. There are still difficulties and bottlenecks in the interconnection between departments in this city. It is still difficult to achieve comprehensive interconnection and interoperability between different law enforcement agencies. Although the system design has reserved docking ports, due to various reasons such as compatibility with different platforms, it is difficult to achieve complete sharing and sharing.

"We should not only promote good experience and practices, but also use case interpretation to form a deterrent effect and persistently implement the major decision of the ten-year fishing ban on the Yangtze River." The members of the Standing Committee suggested that in response to the new situation and problems of illegal fishing, we should strengthen inspection and supervision in key periods, key periods, and key areas, focus on illegal fishing in easily hidden areas such as inter provincial border waters, Jiuduansha wetlands, and important fishing seasons, continue to maintain a high-pressure and strict management situation, strengthen the local government's territorial management responsibility, and continue to carry out "ship cleaning, shore cleaning, and illegal fishing" actions.
