Investigation of size and shape differences depend to sex, age and season on scales of smallmouth lotak (Cyprinion kais)

In this study, a total of 82 (49♀♀, 33♂♂) Cyprinion kais samples from the same location in the river of Tigris were collected and ages of scales taken from front and upper section of lin lateral of dorsal fins of fishes were determined and photographed by an Olympus digital camera with Canon SX7 model binocular under the same conditions and then six landmarks were taken by using tpsDig ver. 2.32 software. Afterwards, procrustes analysis was conducted. After separating shapes and sizes, ANOVA, PCA, CVA/MANOVA and DFA analyses were performed. According to the results of the analyses, there was a significant difference between the samples in terms of gender and size (Size ANOVA: F= 50.6, p
