Using the 335 Scomberomorus niphonius samples collected from off East China Sea and Yellow Sea from September 2017 to March 2018, the relationship between otolith and growth was studied by means of function fitting, variance analysis and wavelet analysis, taking TL,TW,DL,DW,VL,and WL as the basic morphological parameters. Based on the samples of 335 Scomberomorus niphonius collected off East China Sea and Yellow Sea between September 2017 and March 2018, the relationship between the ontogenetic shape changes of otoliths and growth was studied by the basic morphological parameters of otolith length, otolith width, dorsal length, dorsal width, ventral length and wing length, using the methods of function fitting, the ANOVA,the Least Significant Difference (LSD) analysis and wavelet analysis. The results showed that the otolith of Scomberomorus niphoniusis milky white, approximate rectangular, the back convex, the front concave, the outside had more protruding small teeth, serrated, the overall bending to show the tile shape. There was no significant difference between the left and right sagittal otolith. The weight of the otolith and 6-item morphological parameters were significantly correlated with the fork length, and all of them were the best fit results of the exponentiation function. With the growth of Scomberomorus niphonius, the morphological characteristics of the otolith varied significantly with the fork length, and the total length of the otolith was increasing, and the dorsal and ventral regions continued to shrink to the center of the otolith. The length of the posterior region increased, and the wing length increased, with the overall appearance of vertical shrinkage and horizontal growth trend.
