The relation of insulin like growth factor gene (igf-1) with some physiological characteristics of common CARP (Cyprinuscarpio)
ST Aljuboory and MS Al-Khshali
The present study was conducted to identify genotypes of insulin- like growth factor (IGF-I) and its relation with some of the physiological characteristics (glucose, AST &ALT) of common carp Cyprinus carpio in Al-Radhwaniyah Fish reservoir (Baghdad). It has been identified genotypes of insulin like growth factor by using restriction fragment length polymorphism (RFLP) in specified mutation in the site 3759T > G. Results of physiological characteristics showed that the blood glucose rate was affected significantly (p<0.05) by different genotypes as which glucose concentration in TT genotype was 87.87 mg/100, whereas about 67.21mg/100 in TG genotype. Regarding values of transaminase enzymes (AST & ALT) they did not affect significantly by any of genotypes. ALT Value in TT genotypes was 52.66 IU with 46.33 IU in TG genotypes, as for AST, the results were 87.66, 88.33 IU in TG, TT genotypes respectively. The present study conclude that the possibility of credibility upon polymorphism in insulin like growth factor as assign for physiological performance prediction of fish body and select them to be parents for coming generation.
