Core Viewpoint - The development of modern marine ranching in Zhuhai faces several challenges, including insufficient insurance coverage, space conflicts for deep-sea farming, pressure on cost balance and sustainable profitability, and inadequate supporting infrastructure [3][5][6][7]. Group 1: Challenges in Marine Ranching - The insurance products for marine ranching are continuously innovating, but coverage remains insufficient, with a gap in policies during transitional periods and high coverage thresholds [5][6]. - Deep-sea farming in Zhuhai is confronted with limited marine space and conflicts regarding its usage [6]. - There is significant pressure on achieving cost balance and sustainable profitability in deep-sea farming operations [6][7]. - The supporting infrastructure for marine ranching is currently inadequate [7]. Group 2: Recommendations for Development - Strengthening financial insurance innovation and precise supply is essential. This includes integrating policy-based aquaculture insurance into regular government budget expenditures to establish a stable and sustainable financial guarantee mechanism [10][11]. - It is recommended to optimize marine space coordination mechanisms and enhance comprehensive management at sea, including establishing a joint approval coordination mechanism for marine ranching [15][16]. - There is a need to standardize the identification and operational management of aquaculture vessels, ensuring unified recognition and management of various innovative aquaculture vessels [21][22][23]. - Improving supporting infrastructure is crucial, including the establishment of monitoring networks covering aquaculture areas to provide real-time meteorological and oceanographic data [27][29][30].
