Abstract:
The true phylogenetic relations among the Red Sea shrimp resources are yet under dispute. The present study is designed for evaluating the competence of the mitochondrial Cytochrome b gene sequence for exploring the evolutionary variations among some of the Red Sea shrimp species (Penaeus monodon, Penaeus vannamei, Metapenaeus monoceros, Penaeus semisulcatus, Penaeus latisulcatus and Penaeus japonicus). We identified some DNA markers of each evaluated shrimp species. Also, the genetic variations within and among the estimated shrimp species were calculated. The highest value was calculated within P. monodon samples. The lowest value was detected within P. vannamei. Concerning the genetic diversity among the evaluated shrimp samples, the highest value was calculated between Metapenaeus monoceros and Penaeus vannamei. On the other hand, the lowest value was calculated between P. semisulcatus and P. monodon. Also, the results showed that the M. monoceros was distantly related to the other estimated shrimp species. The relatedness values among shrimp taxa are affected by the accuracy of the identification system. The efficiency of the mitochondrial Cytochrome b gene fragment sequences is seemed to deliver exemplary evolutionary variations among the estimated shrimp species. This study advances a new view on the relatedness among the evaluated Red Sea shrimp taxa. More molecular tags (at mitochondrial and nuclear DNA levels) should be developed for the reconstruction of the true phylogenetic relations among various shrimp resources in the future.
