Based on the fish survey data of the offshore waters of southern Zhejiang in August 2016 (summer), November 2016 (Autumn), March 2017 (winter) and May 2017 (spring), the relationship between dominant fish species is determined by niche breadth, niche overlap, cluster analysis, variance ratio (VR) method, chi-square test, association coefficient (AC) and species pair common percentage (PC). The results show that: (1) 169 species of fish are collected, including 26 major species; (2) in the spatial dimension, the niche breadth of Scomber japonicus is the largest (2.83); the niche overlap between Sardinella zunasi and Thryssa chefuensis is the largest (0.97); in the temporal dimension, the niche breadth of Harpadon nehereus is the largest (1.34); the niche overlap of six groups is equal to 1.00; in the spatial and temporal dimension, the niche breadth of Harpadon nehereus is the largest (3.08); the niche overlap between Sardinella zunasi and Thryssa chefuensis is the largest (0.97); (3) the variance ratio analysis showed that the VR deviation is significant, and the overall positive association of the major fish is significant, among which 170 groups of species pair association reached a significant level (χ2≥3.841). The results of the AC and the PC showed that the interspecific connection tended to be positive.
