记者调查发现，十一假期期间海南三亚、陵水的红树林保护区内商业赶海活动泛滥1。大量赶海俱乐部和商贩在保护区内使用被海南省列为禁用渔具的地笼进行捕捞1，这些地笼网距仅6.5毫米，远低于国家规定的25毫米标准1。有赶海教练称其俱乐部至少拥有2000个地笼，单日接待赶海游客超过百人1。
这种开发对刚完成系统修复的红树林生态造成严重破坏1。商业赶海大规模采挖钉螺、沙虫等底栖生物1，导致红树林根系裸露、病虫害加剧1。北京林业大学教授张明祥指出，底栖生物被大量挖捕后会导致红树林死亡或生长不良1。新竣工项目的红树林成活率仅五六成，叶子出现大面积枯黄现象1。
尽管问题严重，但监管形同虚设。陵水县林业局工作人员坦言，因经济利益考虑难以有效处置这些违法行为，相关部门只能采取"打游击战"式的应对1。
An investigation during China's National Day holiday period revealed rampant commercial shellfish and fish harvesting activities within mangrove nature reserves in Sanya and Lingshui, Hainan Province.1 Operators are deploying prohibited fishing equipment known as "ground cages" to catch juvenile fish and shrimp, while simultaneously harvesting benthic organisms including mud snails and marine worms on a massive scale.1
The ground cages being used have mesh sizes of only 6.5 millimeters, significantly smaller than the regulated standard of 25 millimeters.1 One harvesting company operator reported that their club alone maintains at least 2,000 such cages, with the operation welcoming over a hundred visitors daily for commercial harvesting activities.1 Ground cages have been officially designated as prohibited fishing equipment by Hainan Province and are clearly banned under national regulations.1
The destructive harvesting practices are causing severe ecological damage to recently completed restoration projects. Newly established mangrove saplings show survival rates of only 50 to 60 percent, with leaves exhibiting widespread yellowing and browning.1 According to Zhang Mingxiang, a professor at Beijing Forestry University, the removal of benthic organisms directly causes mangrove death or stunted growth.1 Despite the documented harm, local authorities face enforcement challenges; a Lingshui County Forestry Bureau official acknowledged that economic interests hinder effective management, resulting in sporadic and ineffective enforcement efforts.1
