## 1 Introduction  
Large yellow croaker (_Larimichthys crocea_) belongs to _Perciformes, Sciaenidae_ family, _Larimichthys_ genus. It is an important economic fish unique to offshore China, mainly distributed in the south of the Yellow Sea and the East China Sea [1]. Daiqu large yellow croaker refers to the Lusi Ocean, Daiqu Ocean, and Maotou Ocean spawning groups mainly along the coast of Zhejiang Province; it is one of the four major economic fish in the Zhoushan fishery. Fishing grounds off the coast of Zhejiang Province in the 1950s to 1970s, after high-intensity fishing in the fishing grounds off the coast of Zhejiang Province, large yellow croaker resources declined sharply, and the annual output dropped nearly 99.2% [2]. Since the 1990s, measures began to be taken to prevent the depletion of large yellow croaker resources. These measures included closing the port and suspending fishing, establishing large yellow croaker juvenile conservation areas [2], and developing large yellow croaker artificial culture technology, breeding, and releasing. The efforts alleviated the deteriorating momentum of large yellow croaker resources [3]. The most direct methods to improve the quantity of large yellow croakers are aquaculture and release to restore large yellow croaker resources [4]. Cage culture techniques for large yellow croakers date back to the 1980s [5]. After decades of development, the technology of large yellow croaker cage culture tends to be mature, and the yield and quality are constantly improving[PERSON]  
Many studies have been performed to explore suitable habitats or aquaculture areas for economic fish [6; 7; 8; 9]. [PERSON] et al. [10] used Sentinel-2 satellite data to propose a new inversion model of Chlorophyll-a (Chl-a), which could more accurately estimate the distribution of Chl-a in offshore areas (northwestern Mediterranean), thus providing help for the location of [PERSON] culture areas. [PERSON] et al. [8] analyzed the elements of North American catfish and seawater environment through element analysis to find suitable breeding locations for catfish. Furthermore, scholars [11] also pointed out that the influence of environmental factors on the physiology and biochemistry of large yellow croakers should be determined. Meanwhile, a series of horizontal experiments on temperature, salinity, and biological factors were conducted in artificial large yellow croaker areas, and environmental conditions suitable for the growth and survival of large yellow croaker were obtained. Environmental DNA (Deoxyribonucleic Acid) [12] was applied to study the distribution and abundance of large yellow croaker in the East China Sea and established a prediction model of the large yellow croaker fish situation based on relevant environmental parameters. However, there is a lack of research focusing on environmental factor templates based on existing aquaculture areas and multi-source high-resolution data to evaluate potential aquaculture sites. This research constructs an environmental factor template for the large yellow croaker aquaculture area, considering the intricate environmental factors present in such areas. The specific factors included in the template are Sea Surface Temperature (SST), Chlorophyll-a (Chl-a), Nutrients, Suspended Sediment Concentration (SSC), Current, Wind, Disaster Frequency, Average Depth of Aquaculture, Salinity, Upwelling, River plume, Market Proximity, and Marine Traffic. Subsequently, the study develops a method for the graded evaluation of potential aquaculture sites for large yellow croakers. Utilizing this methodology, a site selection plan and a grading system are implemented to identify and prioritize prospective aquaculture zones for large yellow croakers along the Zhejiang coast of China.
