Review Of Fishery Information And Data Collection Systems In China

China’s surface waters cover 20.6 million ha. The aquatic living resources in these waters not only sustain wild natural fishery production, but also support fish production based on stock enhancement and aquaculture. Most inland capture fisheries are concentrated in the major rivers and lakes, whereas reservoirs are dominated by enhanced fisheries. In 2020, the national freshwater fishing output was 1.46 million tonnes, which was a decrease of 20.84 percent from the previous year. Since 2005, the output value of freshwater capture fishing and aquatic products in China has exceeded CNY 20 billion, reaching a peak of CNY 46.577 billion in 2018. With increasing economic development, the role of inland capture fisheries in the social economy has changed. Since the 1990s, there has been a gradual increase in aquaculture and since 2010 a gradual decrease in inland capture fishery production. With the issuance of various fishing ban policies and the strengthening of enforcement actions, especially the implementation of the “10-year fishing ban” on the Yangtze River and the fishing ban on major lakes, inland capture fisheries production has dropped sharply since 2016 and this development is expected to continue due to the increased awareness of the need for ecological protection in large waterbodies, the implementation of the fishing ban policy and the strengthening of law enforcement. However, even though aquaculture production has massively increased and provides the bulk of freshwater fish supply, high-quality aquatic products from natural waters are still highly sought after by consumers.

The rapid modernization of the Chinese Navy is a well-documented reality of the post-Cold War world. In two decades, the People's Liberation Army Navy has evolved from a backward force composed of obsolete platforms into a reasonably modern fleet whose growth is significantly shaking the naval balance in East Asia. The rationale behind China's contemporary rise at sea remains, however, difficult to grasp and few people have tried to see how the current structure of the international system has shaped Chinese choices. This book makes sense of Chinese priorities in its naval modernization in a 'robust' offensive realist framework. Drawing on Barry Posen's works on sources of military doctrine, it argues that the orientation of Beijing's choices concerning its naval forces can essentially be explained by China's position as a potential regional hegemon. Yves-Heng Lim highlights how a rising state develops naval power to fulfil its security objectives, a theoretical perspective that goes farther than the sole Chinese case.

Asian countries are undergoing rapid political, economic and social transformations; meanwhile, there is a growing demand for knowing more about Asia. This Major Reference Set is designed to help general readers as well as specialists to have a good grasp of the latest developments in Asia in the key areas of economic growth, trade, energy, environment, foreign policy and security.With 4 volumes, this set covers all major dimensions of Asia's political economy. Contributors include both scholars and practitioners who provide first-hand description and analysis of fundamental issues in Asia.Peace and political stability are of ultimate importance, with Asia at the forefront of wealth creation in the global economy. Volume 1 unpacks and examines the foreign policy strategies of key states and the role of regional institutions in responding to the security demands of an Asian century.Volume 2 studies the strong economic integration through trade and cross-border investment that has been essential to Asia. The region's future prosperity depends on it being able to remain open and outward-looking. As Asia grows larger and richer, more concerted efforts are required to surmount regional rivalry and to further strengthen the regional architecture of economic cooperation.Volume 3 looks at the emerging economies' thirst for energy that creates huge competition, around which domestic, regional, and international political economy unfolds. Climate change and aspiration for sustainable development further complicate the challenge.Volume 4 offers a comprehensive coverage of subjects on environment and sustainable development in Asia with case studies of selected and representative countries that are at different stages of economic development and facing different environment-related problems and challenges in the twenty-first century.This interdisciplinary set is a fine example of international cooperation, with contributors hailing from different parts of Asia as well as North America and Europe. It is a must-have for anyone keen on understanding Asia's dynamic and changing scene.

The Working Party received national reports of each of the countries and examined the status of fisheries catch and effort data and statistics. It discussed minimum data requirements for effective fisheries management in five generic fisheries types: industrial shrimp, artisanal shrimp, trap fisheries, demersal line and beach seine fisheries.

As the volume of marine big data has increased dramatically, one of the main concerns is how to fully exploit the value of such data in the development of marine economy and marine science and technology.The book covers data acquisition, feature classification, processing and applications of marine big data in evaluation and decision-making, using case studies such as storm surge and marine oil spill disaster.

With the development of earth observation technologies (such as satellite remote sensing, unmanned aerial vehicle, autonomous underwater vehicle, etc.), an era of big data with important and non-negligible spatial/temporal attributes comes. Novel and rigorous spatiotemporal methodologies and models are needed to process and analyze marine big data. Since many marine environmental processes, such as pollutants diffusion, algae distributions etc., vary or evolve across spatiotemporal domains, detecting the distributions and patterns of marine fauna and, particularly in the coastal regions, will improve our understanding of marine systems and can be beneficial in marine environmental management. The goals of this Research Topic, therefore, are two-fold: (a) to develop methodologies and models in theory and applications, including spatiotemporal geostatistics, geographic information system, deep learning, etc.; (b) to quantitatively gain the knowledge of the marine environment. This Research Topic will provide a platform for researchers to share and exchange their new knowledge gained in a spatiotemporal domain of marine or coastal regions. This Research Topic will cover, but is not limited to, the following areas: • Spatiotemporal variations of physical/chemical/biological indicators (such as chlorophyll, temperature, salinity, colorful dissolved organic matter, suspended solids, nutrients, microplastic, etc.) in marine. • Spatiotemporal variations of potential fishing grounds in marine. • Spatiotemporal variations of the ecosystems in coastal regions, such as salt marshes, mangroves, seagrass, macroalgae, etc. • Spatiotemporal distributions of the pollutants (such as heavy metals, polycyclic aromatic hydrocarbon, etc.) in marine and sediments. • Spatiotemporal evolution pattern modeling and prediction of the marine disasters and abnormal phenomena (such as algal bloom, typhoons, SST anomalies, etc).
