Abstract Expanding the new space for marine aquaculture and carrying out deep-sea aquaculture is of great significance for the improvement of China’s offshore ecological environment, the guarantee of food security, the effective use of marine resources, and marine sovereignty. In this study, 180 mariculture species (120 species of fish and 60 species of bivalves) were analyzed. Through the comparison of the temperature tolerance range of each species and the sea surface temperature range of the study area, the species-to-geographical area matching was achieved. Then the average GPI (growth performance index) values of fish and bivalves at various locations in the sea area were obtained. By further restricting on conditions such as offshore distance and depth based on threshold distance, the potential of deep-sea aquaculture in China was quantitative analyzed. The results are that in the areas where the evaluation conditions are met: (1) For fish, the suitable areas for the Bohai and Yellow Sea (BYS), East China Sea (ECS), and South China Sea (SCS) are 19.98, 76.29, and 81.69 104 km2; for bivalves, the suitable areas of the Bohai and Yellow Sea, East China Sea, and South China Sea are 3.02, 4.17, and 2.03 104 km2 respectively. (2) With regard to different sea areas, fish aquaculture can be given priority in the East China Sea and South China Sea; however, the potential value of fish aquaculture in the Bohai and Yellow Sea is the largest, and fish aquaculture in the later stage needs to be more carefully planned and sited to select areas with large potential values as much as possible; bivalve aquaculture can give priority to the South China Sea. (3) With regard to different depths: fish can be preferentially considered for deeper sea areas; and bivalves are suitable for breeding in offshore areas that are closer to the shore and shallower in depth. According to the evaluation results of breeding potential, sea spatial planning can be carried out to provide some reference for management departments and aquaculture enterprises.

DOI:10.1371/journal.pone.0169281URLPMID:28046057 [本文引用: 1] Aquaculture is developing rapidly at a global scale and sustainable practices are an essential part of meeting the protein requirements of the ballooning human population. Locating aquaculture offshore is one strategy that may help address some issues related to nearshore development. However, offshore production is nascent and distinctions between the types of aquatic farming may not be fully understood by the public-important for collaboration, research, and development. Here we evaluate and report, to our knowledge, the first multinational quantification of the relative sentiments and opinions of the public around distinct forms of aquaculture. Using thousands of newspaper headlines (Ntotal = 1,596) from developed (no. countries = 26) and developing (42) nations, ranging over periods of 1984 to 2015, we found an expanding positive trend of general 'aquaculture' coverage, while 'marine' and 'offshore' appeared more negative. Overall, developing regions published proportionally more positive than negative headlines than developed countries. As case studies, government collected public comments (Ntotal = 1,585) from the United States of America (USA) and New Zealand mirrored the media sentiments; offshore perception being particularly negative in the USA. We also found public sentiment may be influenced by local environmental disasters not directly related to aquaculture (e.g., oil spills). Both countries voiced concern over environmental impacts, but the concerns tended to be more generalized, rather than targeted issues. Two factors that could be inhibiting informed discussion and decisions about offshore aquaculture are lack of applicable knowledge and actual local development issues. Better communication and investigation of the real versus perceived impacts of aquaculture could aid in clarifying the debate about aquaculture, and help support future sustainable growth.
