Firstly, it outlines the main content of the study, analyzes the innovative points of the study, and the contributions of its research field. Secondly, it provides its own opinions on the research direction of the paper, summarizes the impact of climate change on the distribution of marine fish (taking the Yellow Sea and Bohai Sea of China as an example), and provides comprehensive awareness and understanding for everyone, encouraging individuals to take initiative and actively address global climate challenges, making contributions to the sustainable development of marine life. 1 Overview of Research Content The research content of this article aims to predict the impact of climate change on fish distribution in the Yellow Sea and Bohai Sea regions of China by constructing an integrated model. To achieve this goal, the research team collected 3 185 effective fish distribution records and 9 environmental variables, and used the integrated method of species distribution models (SDMs) for modeling and prediction. The research results show that the constructed integrated model exhibits high accuracy in predicting fish distribution, with evaluation indicators including average AUC, Kappa, and TSS values of 0.97, 0.82, and 0.84, respectively. The study also identified the main environmental factors affecting fish distribution, and found that salinity and temperature near the seabed (Figure 2) are important factors affecting fish distribution. At present, the number of important fish species in the Yellow Sea and Bohai Sea is relatively low in the Bohai Sea and relatively high in the Yellow Sea. However, future predictions indicate that with the impact of climate change, the geographical distribution of fish will undergo significant changes. The prediction results indicate that there will be interspecific differences among different fish species, and the number of species with reduced distribution will be greater than that with expanded distribution. The occupied areas of coastal and temperate fish are expected to shrink, while scattered areas in the central and southern Yellow Sea, coastal waters near the Shandong Peninsula, and the northern East China Sea may experience an increase in important fish populations (Allouche et al., 2006).
