Grading Assessment of Temperature Thresholds and Suitable Temperature Zone Division for Typical Species in Marine Ranching

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