长江禁渔后，隐蔽捕捞如何破解？

Core Viewpoint - The implementation of a 10-year fishing ban on the Yangtze River has led to a significant reduction in illegal fishing activities, but new methods and technologies are being employed by offenders, posing challenges for enforcement [1][3][4]. Group 1: Policy Impact - Since the fishing ban began on January 1, 2021, illegal fishing cases have decreased significantly, with the number of fish species monitored in the Yangtze River increasing from 46 to 104 [3]. - The enforcement of the fishing ban has resulted in a drop in the illegal fishing crime rate in Chongqing from 53% in 2022 to 9.7% by September 2025 [3]. Group 2: New Illegal Fishing Methods - Offenders are using advanced equipment such as drones with night vision, electric fishing tools, and even diving suits to conduct illegal fishing, particularly in areas where administrative oversight is weak [3][4]. - Criminal groups are increasingly operating in cross-border river sections during late-night hours or in foggy conditions to evade detection [3][4]. Group 3: Economic Incentives - The high market price for wild Yangtze fish, with common species priced between 40 to 60 yuan per kilogram and rare species like the Yangtze sturgeon fetching much higher prices, drives illegal fishing activities [4]. - The recovery of fish populations has made illegal fishing more lucrative, allowing offenders to potentially catch hundreds of kilograms in just a few hours [4]. Group 4: Enforcement Challenges - Despite a decrease in overall illegal fishing cases, significant incidents still occur, and offenders are becoming more technologically sophisticated, complicating enforcement efforts [6]. - The rapid withdrawal of offenders after committing illegal acts presents substantial challenges for evidence collection and prosecution [4][6]. Group 5: Recommendations for Improvement - Experts suggest enhancing cross-regional law enforcement collaboration and improving monitoring capabilities in weak oversight areas using AI and advanced surveillance technologies [7][8]. - Encouraging community involvement in fish protection and establishing reward systems for reporting illegal activities can help supplement regulatory efforts [8].
