Population genetics of

Sardinella gibbosa bleeker, 1849) in the coastal area of vietnam

Sardine fish (Clupeiformes: Clupeidae) are about 50 genus of species, widely distributed, predominantly pelagic, school and migratory. Sardinella gibbosa were collected from four geographic areas: Phu Quoc Khanh Hoa, Da Nang and Cat Ba. Phylogram of species diversity is based on Neightbour joining algorithm using the sequences of control region gene (CR) and 16S of mitochondrial DNA from 4 populations of S. gibbosa. Haplotype network was built using the Network software. The results showed that the control region gene (1122 bp) of 80 individuals (collected at Phu Quoc, Nha Trang) has a total of 32 haplotypes with haplotype diversity was h=0,916±0,00041. For the 16S gene (550 bp) of 81 individuals with a total of 31 haolotype detected and haplotype diversity was h= 0,804 ±0,0017. Phylogram and Haplotype network shows the widely connections between S. gibbosa populations along the coast of Vietnam, except Phu Quoc population. Ocean current and outflow of Mekong river could be consider as a barrier to larval dispersal and population structure formation
