Abstract
This study was conducted to compare the morphological characteristics of wild and farmed common carp. In total 70 samples of common carp, including 25 samples of wild from Torkaman port and 45 samples of farmed common carp from Silver carp center in Gilan province were collected. Morphometric results were standardized using Elliott formula, and then principal component analysis (PCA) and discriminant function analysis (DFA) were used. Independent t-test was used to evaluate the significance of traits between these two populations. The results of this study revealed that the two populations of wild and farmed common craps were completely separated from each other, using PCA and individuals were assigned to their true population with high accuracy (98%) based on DFA. Among the 33 truss distances that were analyzed, 16 distances showed a significant difference between two populations (p<0.05). The results showed that the studied populations can be distinguished by many morphological differences, especially by dorsal fin length, pectoral fin length, pelvic fin length, anal fin length, dorsal fin width, body width, tail stem width, distance between pectoral and pelvic fin, distance from mouth to dorsal fin and the distance from the mouth to the anal fin. Overall, the results showed that the population of wild carp was significantly different from the population of farmed common carp from the morphological point of view.
Gene ontology and KEGG enrichment revealed potentially related trait potential and genes associated with body shape, scaling patterns, and skin color.«نتایج کامل» بار نشدامتحان مجدد
