This seemingly unhurried process is actually reshaping the global fishery landscape. The distribution of many fish species is shifting towards high-latitude regions, their reproductive rhythms are disrupted, and their population structures are beginning to loosen. Take high-latitude regions as an example. Arctic cod seems to still be able to "reap some benefits" from the warming at present, but this is only a temporary respite. Once ocean warming and acidification intensify further, even the strictest fishery management will be difficult to avoid the risk of population collapse (Hansel et al., 2020). In contrast, the problems brought about by acidification are more concealed - they do not manifest immediately but start to have an impact from the early stages of fish development. In a high CO₂ environment, the mortality rate of Atlantic cod larvae will rise sharply, and the population's replenishment capacity will also decline accordingly. What's more troublesome is that this chemical change does not only affect fish. When the ecological
