On March 26, the ocean-going fishing vessels 'Zhongyang 13', 'Zhongyang 23', and 'Zhongyang 29' arrived at Dachan Bay, Shenzhen, with a cargo of various fish species, including yellowfin tuna and flatfin swordfish, all quick-frozen at sea. These were to be processed by Shenzhen Shuiwan Ocean Fisheries Group. To ensure the fish remained fresh, Dachan Bay Customs expedited the clearance process through measures like advance declaration, a tax-free policy for self-caught aquatic products, and a 'green channel' for priority review. Additionally, innovative steps such as video surveillance and dedicated berths were employed to guarantee 'zero delay' in the cold chain process, highlighting a strong commitment to supporting the fishing industry and streamlining customs procedures.
