The construction of Marine Ranching is a safe, efficient, and sustainable way to achieve marine environmental protection and biological resource utilization. In recent years, the construction of Marine Ranching in coastal provinces in China has developed rapidly, but due to the late start, the ability to guarantee ecological security is weak. In this paper, Pseudosciaena crocea was selected as typical aquaculture species in Marine Ranching of the East China Sea, by integrating the experimental data from former studies effect of temperature on the Specific Growth Rate of this aquaculture species was evaluated via performing quadratic regression fitting, the results reveal that the optimum temperature ranges for Pseudosciaena crocea are 25.3– 30.7°C, the preferred range is 18.9–25.3°C, the unsuitable temperature ranges were lower than 18.9°C and higher than 30.7°C. Further, based on the aquaculture specifications, commodity specifications , and aquaculture cycle, the Specific Growth Rate to be achieved by the aquaculture species is determined, and the corresponding temperature threshold and graded evaluation were obtained, finally, the suitable water temperature distribution area of the Pseudosciaena crocea was evaluated based on the hydrological data observed in the East China Sea during 2020–2021.
