Title

INVESTIGATION OF MORPHOMETRIC VARIATION AND DIFFERENTIATION SIAH MAHI, CAPOETA CAPOETA GRACILIS, IN TAJAN RIVER

Pages

  517-535

Abstract

 This study was designed to evaluate VARIATION AND DIFFERENTIATION in the TAJAN RIVER and investigation SHAHID-RAJAEI DAM effects upon Siah Mahi. A total 65 fish specimens were collected by electeroshocker set that 31 individual related to up stream station and 35 individual related to down stream station.28 morphometric factor and 22 morphometric specialties were measured and was standardized with Beacham formula.Univariate analysis (One-Way ANOVA) of 16 characteristics among the samples showed significant differences with varying degrees that showed relatively high phenotypic diversity in the CAPOETA CAPOETA GRACILIS population in the two zones sampling. The data were subjected to a principle component analysis (PCA) which grouped in eight factors, and scatter plot showed that two stations were differenced.Discriminate function analysis (DFA) or the overall random assignment of individuals into their original groups was high (98.5% for morphometric factor and in case of relative measurements was 92.4%), indicating that these specimens are highly divergent from each other. Clustering analysis based on Euclidian distance also showed these stations are separated. The results of this study indicating that the dam probably severely limit downstream dispersal by Siah Mahi, and eliminate upstream migration altogether. Consequently construction of SHAHID-RAJAEI DAM on TAJAN RIVER presumably could create two morphologic different populations of C. c. gracilis in the upstream and downstream.
