Based on the sea surface temperature (SST), which is the most dominant environmental climate factor affecting the distribution of squid, the potential habitat changes of Ommastrephes bartramii in July to October in 1996−2005, 2021−2030, 2051−2060 and 2090−2100 are analyzed using maximum entropy (MaxEnt) model with the historical climate data from 1996 to 2005 and the projection climate data from RCP4.5 and RCP8.5 scenarios. The results show that the fishing grounds of O. bartramii performs a seasonal north-south migration. Meanwhile, as the seasonal north-south migration of O. bartramii may be affected by the suitable SST range in fishing season, with the feature climate change the potential habitat distribution of O. bartramii from July to September in 2021−2030, 2051−2060 and 2090−2100 will move northward and the suitable habitat area will increase compare to 1996−2005 under both scenarios of RCP4.5 and RCP8.0. Under scenario of RCP4.5, the potential most suitable habitat for O. bartramii will move northward by 1°−2° and the suitable habitat area will increase by 3%−13% by the end of the 21st century. Under scenario of RCP 8.5, the potential most suitable habitat for O. bartramii will move northward by 3°−5° and the suitable habitat area will increase by 42%−80% by the end of the 21st century.
