Comparison Of Morphometric And Meristic Of Bream (Abramis Brama Orientalis Berg 1905), In Caspian Sea And Anzali Wetland

During 1381 year, morphometric specialities , meristic and proportion of morphometric particulars of the bream (Abramis brama orientlis) the Caspian sea (90 pieces) and Anzali wetland (120 pieces) was studied and compared. According to results, average of changes coefficient the above factor in the bream of Caspian sea were respectively 22.36 , 3.24 and 7.56 percent and in the bream of Anzali wetland were 22.76 , 4.63 and 21.56 percent. Meanswhile , it is observed the different meaningful of statistical (ANOVA) , from 40 morphometeric factor, 16 morphometric spacialities respectively in 33 , 3and 26 factor. According to test of Factor Analysis bream of this two area choosing in 6 first morphometeric(Total leanght , forke length , standard length , head length , head height , snout length) 80.02% changes (rate of KMO equal 0.94) , in 4 first meristic(number of scale the lateral line , number of scale under the lateral line , number of scale above the lateral line , number radius of dorsal fin) factor 60.42 % changes (rate of KMO equal 0.47) and in 7 first factor proprtion of the morphometeric(proportion of head length to standard length , head height to head length , snout length to head length , mount width to head length , mount length to head length ,throat length to head length and eye diameter to head length) 73% rate of KMO equal 0.82 of this factor , caeuse separating of two population from together. So, according to the Descriminatiion test according to two first and secind factors of morphometeric(Total leanght , forke length) , meristic(number of scale the lateral line , number of scale under the lateral line) and proportion of the morphometeric specialities (proportion of head length to standard length , head height to head length)of the Abramis brama orientalis of this two area will totally separate (rate of focus espectively equals 0.88 ,0.3 and 0.86). finally , with attention to results , we can say that there are significant different between the bream of Caspian sea and Anzali , wetland in morphometeric factors , while , this different is very little in meristic factors , the reason of this differents , is causing of variation condition of habitat and the effected on the meristic factors. Because , this factor is not affected on the meristic factors is dependant of genetical changes.
