| Zusammenfassung: | The
IGF-I
is a significant peptide hormone to cell growth, development, reproduction, and metabolism of teleost fish. This study was conducted to investigate the
IGF-I
gene polymorphism and to reveal the association between the genotypes of
IGF-I
gene and growth traits in 80 harvest size European sea bass (
Dicentrarchus labrax
, L.) reared in İzmir region of Turkey. The 821 bp long exon 1 and 5’ UTR regions of
IGF-I
gene were amplified, and PCR products were analyzed via DNA sequencing method. Two novel single nucleotide polymorphisms (SNPs) such as g.46672A > G and g.46749C > T in the 5’ UTR region of
IGF-I
gene in the European sea bass were detected for the first time with this study. Associations between the genotypes of
IGF-I
g.46749C > T locus and body weight were found statistically significant (
p
T and g.46672A > G loci were found significantly associated with total length (
