Abstract:The otoliths from Pseudoplouronectes yokohamae,Rasper variegates and Platichthys bicoloratus were analyzed by the morphological index and elliptical Fourier analysis.The results by independent-samples T test and one-way analysis of variance were similar.In the morphological index,the results of principal component analysis confirmed that the cumulative contribution ratio was 88.377%;discriminant analysis revealed that the average discriminant accuracy was 98.1%;the scatter plot of scores based on the first two canonical discriminant functions showed that three species of pleuronectidae were separated.In the elliptical Fourier analysis,the results of principal component analysis revealed that the 18 principal components explained as high as 93.999% of the variation in total;discriminant analysis revealed that the average discriminant accuracy was 100%.In short,both of the two methods were effective tools in species discrimination of three species from Pleuronectidae.
