“…34 Since 1995, there has been a notable deterioration in the environmental condition, leading to proposals for safeguarding the lagoon through the construction of wastewater treatment facilities. 35 The adverse impacts of climate change on shrimp production and aquaculture are evident. 13,14,34 Genetic diversity analysis based on the mtCOI gene segment could provide crucial data for proposing measures to conserve aquatic resources.…”

This study investigates the genetic diversity and population structure of the greasyback shrimp, Metapenaeus ensis (De Haan, 1844), within the Tam Giang – Cau Hai lagoon, Vietnam, by analyzing mtCOI genes from 91 individuals collected across four populations in nine sampling locations. High genetic diversity was found, with 34 unique haplotypes and 38 genetic variations identified. Most genetic variation occurred within populations (AMOVA), suggesting high gene flow. Low and non-significant Fst values and close genetic distances confirmed minimal differentiation among populations. These findings provide the first insights into M. ensis population genetics in this lagoon, informing conservation and management efforts. Understanding genetic diversity is crucial for sustainable management and conservation of marine species. This research aids in understanding population resilience, potential impacts of overfishing, and may assist in developing sustainable harvest strategies of this economically important shrimp species.

“…Groups of environmental capacity elements are classified and weighed, and the main factors affecting the ECC of an area of interest are determined. 22 However, this method is influenced by the subjectivity of experts because of the weighting and matrix construction processes.…”

“…The ECC of a coastal area is very complex, and many factors, such as water resources, waste treatment capacity, hydrodynamic and biochemical processes in the water body, regional population, urbanization rate and gross domestic product, need to be considered. 22 Since the complexity and diversity of regional economic environment systems make it impossible to assess all activities to determine the MECC, 16 typical and quantifiable indicators that represent the practical status of the YSLME MECC were selected in this study to construct the evaluation index system (Table 1). Both development and constraint variables of ECC were considered, and the Delphi method was applied to ensure the efficacy of the index system.…”

Under the framework of sustainable development of the marine economy, much consideration has been given to various coastal states for the large marine ecosystem (LME) concept. The Yellow Sea LME (YSLME) is one of the most heavily exploited LMEs in the world, and its sustainable development has been heavily threatened by human activities, with negative impacts on the economies of bordering countries, such as China. With the aim of mitigating environmental threats by developing a low-carbon economy based on low pollution, low energy consumption and low emission, an index system for evaluating marine environmental carrying capacity (MECC) was established in this study based on the entropy method, and gray relation analysis (GRA) was carried out to assess the MECC of three main coastal cities (Qingdao, Yantai and Weihai) along the YSLME in China. The results verified the importance of the environmental carrying capacities (ECCs) of marine resources, marine economy and marine environmental governance for the sustainable development of the YSLME, and revealed paths for improving the MECC of the studied cities. Based on the results, suggestions for ecosystem-based management of a low-carbon economy were provided to help government departments to reasonably develop and utilize marine resources, protect the marine environment and implement sustainable development strategies.

“…For example, the construction of the ECC indicator system in inland and coastal areas is different, and the research on ECC in different areas (such as forests and mining areas) also needs to be adjusted accordingly [33,34], which reflects the development of ECC in comprehensive, regional and broad directions [35,36]. In addition, researchers have continuously explored the feasibility of studying ECC in various fields and have made good progress in some of them that have not been involved in ECC, such as water resources, tourism, and resource development, and have gradually become popular [19,[37][38][39]. In addition, In the past five years, the rapid development of geographic information systems has made the spatiotemporal dynamic analysis of ECC gradually become a research hotspot, and researchers have begun to analyze and predict the trend of ECC [40].…”

With the rapid development of coastal cities, environmental problems are becoming increasingly severe. Therefore, it is imminent to assess the environmental carrying capacity (ECC) of coastal cities. We take Yueqing City, China, as the study area and establish an ECC evaluation system. For the objectivity and scientificity of this study, the coefficient of variation-back propagation neural network (CV-BPNN) method is used to determine the weight of the indicators and a multi-temporal evaluation is conducted. This paper also explores the relationship between coastline changes and ECC variations for the first time. The results indicate: (1) The ECC of Yueqing City first decreased and then increased, and the inland ECC is better than the coastal area. The future trend is expected to rise. (2) The coastline is continuously extending seaward, and the natural coastline retention rate gradually declines. (3) The coupling coordination degree between the change in the ECC and the change in the coastline shows a trend of “first fluctuation, then stability, and then decline,” and the ecological environment situation was still challenging. (4) Based on the above results, some suggestions are put forward to strengthen coastal ecological development and promote the sustainable development of coastal cities.
