“…These cages are primarily utilized for the cultivation of various types of aquatic creatures, such as small yellow croaker (Larimichthys polyactis), puffer fish (Takifugu rubripes), and Japanese seabass (Lateolabrax japonicus) [14]. Deep-sea cages are highly equipped and possess robust wind and wave resilience, serving as a means for cultured species such as Atlantic salmon (Salmo salar) and pompano (Trachinotus ovatus) [1]. Raft facilities, involving the culture of seaweed (e.g., kelp Laminaria japonica) and shellfish (e.g., pacific oyster Crassostrea gigas), consist of raft frames, floats, and ropes, and are anchored to the seabed with cables [15].…”

“…The swift advancement of facility fisheries has generated considerable economic benefits, particularly in China. The widespread distribution of facility fishery areas presents an obstacle for efficient and precise monitoring using conventional management approaches, thereby impeding the sustainable and systematic growth of aquaculture [1,2]. Facility fisheries are also susceptible to impairment from marine disasters, such as storm surges, waves, and sea ice [3].…”

“…The implementation of scientific planning is therefore advantageous in comprehending the spatial arrangement of aquaculture areas, regulating and overseeing fishery facilities, and efficiently averting and alleviating the adverse consequences of marine calamities. However, the dispersion of fishery facilities and inadequate development of surrounding road infrastructures present certain challenges in conducting comprehensive field surveys [1]. The use of image recognition techniques based on satellite remote sensing imagery confers a distinctive benefit in providing precise, uninterrupted and cost-effective feature data for the monitoring and administration of facility fishery areas [4].…”

The predominant form of aquaculture is the facility fishery, which is also subject to significant impacts from marine disasters. Conducting research on the extraction of facility fishery areas based on remote sensing technology is crucial to efficiently comprehending the configuration of coastal culture patterns and to establishing scientifically sound plans for managing and administering these areas. The extensive dispersion of facility fishery areas in coastal regions poses a challenge to the conduction of comprehensive field surveys. The utilization of satellite remote sensing images for information extraction has emerged as a significant area of research in the fields of coastal fishery and ecological environment. This study provides a systematic description of the current research status of coastal fishery area extraction methods using remote sensing technology from 2000 to 2022 reported in the literature. The methods discussed include the visual interpretation method, image element-based classification, object-based classification, supervised classification, unsupervised classification, and neural network classification. The extraction accuracy of each method in the coastal facility fishery area is evaluated, and the advantages and disadvantages of these methods, as well as their limitations and existing problems, are analyzed in detail, to construct a reference framework for the investigation of the high-precision extraction of facility fishery areas from satellite remote sensing images.

“…However, existing studies rarely use the environmental risk index as an evaluation index. In addition, in recent years, aquaculture in China has been restricted and the suitable aquaculture area was shrinking (Long et al, 2024), ascribed to the acceleration of coastal urbanization and industrialization combined with the ecology and environment protection of coastal zone. The impacts of human activities on marine ecosystems generally vary in space, implying that ecosystem health evaluation of the aquaculture bay based on the smaller evaluation unit is necessary.…”

Maintaining the health of coastal aquaculture ecosystems is crucial for sustainable development. Therefore, establishing a specific ecosystem health assessment index system for aquaculture bays is paramount. This system allows for the evaluation of the health status of these bays and aids in the planning and restoration of fishery habitats. Utilizing the well-known “Pressure-State-Response” framework, a comprehensive evaluation index system with 14 indicators was developed. Additionally, the analytic hierarchy process and entropy weight methods were employed to assess the ecosystem health of Sansha Bay, a representative aquaculture bay in Fujian Province, China. The results revealed variations in health status across four zones in 2020, categorized as “good” or “excellent”. However, the security index was more spatially distributed and classified from “fair” to “safety”. Key indicators critical to sustaining the health of the aquaculture bay ecosystem included the regional environmental risk index, the proportion of industrial discharge outlets, the zooplankton species diversity index, the phytoplankton species diversity index, the molar ratio of phosphorus to nitrogen, and the size of nature reserves. According to the assessments of ecosystem health and ecological security, vigorous endeavors in aquatic ecology are paramount to ensure the enduring sustainability of aquaculture, with a specific emphasis on Zoning 1 and Zoning 4. These findings not only enhance and expand the methods for assessing the health of aquaculture bay ecosystems but also provide a scientific basis for the conservation of fishery habitats and the green, high-quality development of the aquaculture industry in Sansha Bay.

“…Shellfish is one of the most important non-fed species in aquaculture, this is primarily due to their ability to feed directly on plankton present in the water column, thereby eliminating the need for an external food source (Maar et al, 2023). Owing to the deterioration of coastal water quality and spatial limitations, aquaculture is increasingly being extended into deeper oceanic regions (Long et al, 2024). Nonetheless, as aquaculture has developed, there is now a greater chance of it being exposed to high winds and waves.…”

Suspended shellfish aquaculture, utilizing longlines and buoys fixed on the sea surface, is a crucial source of global seafood. However, typhoons, as the most common disasters in coastal regions, can generate massive waves and pose a threat to the safety of suspended aquaculture facilities. Therefore, it is essential to investigate the risk levels associated with suspended aquaculture farms during typhoon waves. The example of a large-scale suspended mussel farm in the East China sea was examined in this study. The wave conditions under extreme wind conditions (25m/s) and different typhoon paths were predicted using the SWAN model and modeled results compared well with the observed wave and wind data. The results indicated that when the center of the east-side typhoon was located at the same latitude as the farm, it will face the highest risk level. However, for the west-side and intermediate sweeping typhoons, the risk level reached highest in the farm, when the typhoon center is lower than the latitude of it. Under the combined effects of wind fetch and topography, the risk level in the southeast farming area of the island is the highest under different wind conditions. The farms to the northwest of the island face a higher risk level during the passage of east-side sweeping typhoons, while the southern farms of the island experience an elevated risk level during the west-side and intermediate sweeping typhoons. It is suggested that farming regions with lower risk levels are more conducive to the cultivation of species with longer culture cycles. Conversely, regions considered at higher risk are more suitable for species with shorter culture cycles. The study affords a reference for the optimization and insurance of suspended aquaculture farms.
