Based on data of climatic and environmental factors in Shandong coastal waters from 1979 to 2020,variance inflation factor analysis,generalized linear additive model and random forest model were used to analyze the influence of fishing pressure and climate change on Acetes catch before and after summer fishing moratorium and the key climate factors were selected.The results showed that,there was a significant correlation between the catch and fishing effort in the coastal waters of the Bohai Sea where sea surface temperature was an important environmental factor affecting the variation of the catch,there was a significant positive correlation between the catch of Acetes and sea surface temperature in the Bohai Sea(P＜0.05).This study can provide a historical basis for the assessment of the maximum catch,the establishment of the quota and the evaluation of special fishing effect of Acetes in Shandong Province.
