| Abstract: | According to the seasonal fishery resource survey data from 2016 to 2017 in the adjacent waters of Changshan Islands, two-stage generalized additive model is used to examine the spatio-temporal distribution of Paralichthys olivaceus abundance and its relationships with relevant factors. The results show that the abundance of P. olivaceus exhibites obvious seasonal variation, and the abundances in spring and autumn is higher than those in winter and summer. In spring and autumn, it mainly distributes in the waters of 120.5°?122.5°E; and in summer and winter, it moves to the waters with suitable water temperature. The occurrence probability of P. olivacvacus is mainly affected by season, bottom salinity and bottom temperature. The probability of occurrence is relatively high at the salinity of 31. The relative abundance of P. olivaceus are mainly affected by bottom salinity and depth, and the relative resources is higher at the depth of 33 m. The spatio-temporal heterogeneity of the abundance distribution of P. olivaceus is affected by multiple factors in the adjacent waters of Changshan Islands. |
