Uroteuthis edulis as the main catch species of the torch light fishery in Taiwan. Due to the cephalopod resources was affected by the environment and fluctuated between years, it was so vulnerable to the impact of overfishing and leaded to collapse, highlighting the importance of resource assessment. In this study, the catch per unit of effort (CPUE) is used as a resource indicator, and the surface water temperature (SST) and sea surface chlorophyll-a (SSC) of the fishing sites are used as the environmental factorto applied to the Generalized Additive Models (GAM) to establish the spatial pattern of the distribution of the Uroteuthis edulis resources. This study shows that the Uroteuthis edulis has different optimal catch water temperatures in different months. The SST from April to June has the best catch rate around 24 °C. The best catch water temperature rises to 26 °C in July. It rises to 28 °C in AugustSeptember. The effect of each month's SSC concentration on its CPUE is negatively correlated. The optimal mode selection factors obtained in different months are different. The integration mode of SST and SSC is the best choice mode from April to June, and the SST is used between July and September.
