Abstract Evaluation and prediction of the changes in the habitat suitability of jumbo flying squid Dosidicus gigas in the Southeast Pacific Ocean can help understanding of the dynamics of their resource and fishing ground, and make sustainable exploitation of fishery resources. A habitat suitability index (HSI) model was developed based on the fishery data of jumbo flying squid collected from Squid-jigging Science and Technology Groups at Shanghai Ocean University fishing data and two critical environmental variables including sea surface temperature (SST) and sea surface height anomaly (SSHA) using arithmetic method model, and compared the difference in squid stock dynamics from September to December between 2010 (a La Niña year) and 2015 (an El Niño year) in the Southeast Pacific Ocean. It was found that the abundance of jumbo flying squid was much higher in the La Niña years (2010) than that in the El Niño years (2015), with much lower SST and SSHA from September to December in 2010 than those in 2015. It was clearly shown that the areas of suitable habitat in each month of 2010 were larger than those in 2015. Moreover, the suitable habitat of jumbo flying squid in 2010 moved to the northern waters comparing to 2015, leading to the northward shift of latitude gravity centers of fishing ground in 2010. This finding suggested that the analysis of fishing ground based on the habitat suitability index model can explain the year-to-year difference in squid abundance and distribution of jumbo flying squid in the Southeast Pacific Ocean.
