Different on the abundance of Pampus argenteus in Persian Gulf exceeding in variety comparing to Gulf of Oman

Abstract

Silver pomfret fish (Stromateidae) is a family of Perciformes order. One species of this family is Pampus argenteus known as silver pomfret and lives in different parts of the Persian Gulf and Gulf of Oman. Therefore, the genetic relationship between its populations is so important. In this study, eight samples of Pampus argenteus were collected from four locations involved: Emam Khomeyni, Bushehr and Bandar Abbas in Persian Gulf and Chabahar in Gulf of Oman. Cytochrome b gene and D-loop region of mitochondrial DNA on these samples are analyzed. These genes are carried out using PCR with specific mtDNA primers and sequenced. Then, the evolutionary history was inferred by using the maximum-likelihood method. Evolutionary analyses were conducted in MEGA7. According to the phylogenetic trees, with translocations in Persian Gulf to Gulf of Oman, similarity decreases slowly. Chabahar1 sample in phylogenetic tree of cytochrome b is phylogenetically near China Sea samples. The reason may be migration from ocean to gulf throughout the centuries and Chabahar is in Gulf of Oman and locationally near the Arabian Sea and Indian Ocean. In D-loop region, results are similar to cytochrome b excepting one sample (Emam Khomeyni1). D-Loop in samples shows modification more than cytochrome b for the reason absence of protein product.
