“…In 2010, the State Council issued and implemented the strategy and action plan for biodiversity conservation in China (2011China ( -2030, which provided guidance for the priority areas of inland, water, ocean, and coastal biodiversity conservation. By 2019, China had established 271 protected areas that include oceans (Zhou et al, 2021). They cover 12.4 million hectares of the ocean but represent only 4.1% of China's maritime area (Zhou et al, 2021).…”

Identifying the spatio-temporal distribution hotspots of fishes and allocating priority conservation areas could facilitate the spatial planning and efficient management. As a flagship commercial fishery species, Largehead hairtail (Trichiurus japonicus) has been over-exploited since the early 2000s. Therefore, the spatio-temporal management of largehead hairtail nursery grounds could effective help its recovery. This study aims to predict juvenile largehead hairtail distribution patterns and identify priority conservation areas for nursery grounds. A two-stage hierarchical Bayesian spatio-temporal model was applied on independent scientific survey data (Catch per unit effort, CPUE) and geographic/physical variables (Depth, Distance to the coast, Sea bottom temperature, Dissolved oxygen concentration and Net primary production) to analyze the probability of occurrence and abundance distribution of juvenile largehead hairtail. We assessed the importance of each variable for explaining the occurrence and abundance. Using persistence index, we measured the robustness of hotspots and identified persistent hotspots for priority conservation areas. Selected models showed good predictive capacity on occurrence probability (AUC = 0.81) and abundance distribution (r = 0.89) of juvenile largehead hairtail. Dissolved oxygen, net primary production, and sea bottom temperature significantly affected the probability of occurrence, while distance to the coast also affected the abundance distribution. Three stable nursery grounds were identified in Zhejiang inshore waters, the largest one was located on the east margin of the East China Sea hairtail national aquatic germplasm resources conservation zones (TCZ), suggesting that the core area of nursery grounds occurs outside the protected areas. Therefore, recognition of these sites and their associated geographic/oceanic attributes provides clear targets for optimizing largehead hairtail conservation efforts in the East China Sea. We suggested that the eastern and southern areas of TCZ should be included in conservation planning for an effective management within a network of marine protected areas.

“…We found that when only MPAs are considered toward global targets, only 4.50% of marine and coastal habitats are protected, which falls far short of the Aichi target of 10% protection by 2020. Other recent publications have similarly estimated that about 5% of marine environments in China are protected by MPAs ( 18 – 20 ), although some differ in spatial scope from this study by incorporating a larger area of claimed territorial seas than the UN-defined EEZ. If AGRs are included in the statistics, then China may meet or even modestly exceed the current target, depending on the extent to which AGRs qualify as OECMs.…”

“…Despite China’s global political and environmental relevance, little is known about the 270+ MPAs reported to exist in the country ( 18 – 20 ). For example, as of October 2021, the United Nations (UN)–officiated World Database on Protected Areas ( www.protectedplanet.net ; accessed 14 October 2021) only contained 15 Chinese MPAs in its dataset.…”

“…Terrestrial nature reserves in China capture only 17.9% and 16.4% of the available habitat area for threatened mammals and birds, and even worse, 10.0% and 8.5% for amphibians and reptiles [ 9 ]. The marine PA network needs much more attention in both area and connectivity [ 10 ].…”

“…These top-level designs will integrate and optimize PAs that existed to cover more key areas for wildlife and ecosystem services, and expand to improve niche representation. In addition, the establishment of a marine national park is urgently needed to strengthen the protection of marine biodiversity [ 10 ]. Meanwhile other types of lands with conservation value, such as farmland, should be incorporated into protection plans [ 11 ].…”
