| Abstract | ||
| A study of molecular diversity and phylogenetic analysis of eight Carangid species, which are ecologically and economically important species, was carried out using Divergent Domain D11 of 28S rRNA Gene. The size of the consensus sequences of Divergent Domain D11 of 28S rRNA Gene ranged from 490 in Carangoides bajad, to 496 in Carangoides malabaricus. The average content of A+T was lower than C+G. The average content of C+G slightly changing among the eight fishes, it was 55.3% in Carangoides bajad; 55.7% in Carangoides chrysophrys; 55.5% in Carangoides malabaricus; 55.6% in Caranx melampygus; 55.3% in Caranx sexfasciatus; 55.6% in Elagatis bipinnulata; 55.5% in Scomberoides lysan and 55.9% in Trachinotus ovatus. Genetic distance among Carangid species ranged from 0.000% to 0.005%. Overall the distance value among all fishes was 0.005%. The phylogenetic relations among our species were inferred by three methods, the Maximum Likelihood, Neighbor-Joining, and Minimum Evolution. The three different phylogenetic approaches resulted mostly in similar tree topologies and the clades. Results of Divergent Domain D11 of 28S rRNA revealed the species belong to two genera Carangoides and Caranx were genetically related to each other more than the rest genera; Elagatis, Scomberoides, and Trachinotus. This investigation could be utilized for genetic relationship and association analyses in the taxonomy studies of Carangid fishes. | ||
