The correlation between saprobity and mitochondrial genes of indicator fish species based on molecular phylogeny

Abstract

Aim and Scope: The aim of the work is to reveal the correlation between saprobity and mitochondrial genes of COI-5p and 12S rRNA of indicator fish species based on phylogenetic tree reconstruction. Material and Methods: The article was made a first attempt to reveal the correlation between the saprobity and the mitochondrial genes of indicator freshwater fish species based on phylogenetic trees reconstruction of the COI-5p and 12S rRNA genes by neighbor -joining method and maximum parsimony method. Result and Discussion: Preliminary results show the clusterization of freshwater fish species by saprobity zones. The statistical significance of phylogenetic tree clusters containing indicator fish species according to COI-5p and 12S rRNA genes was evaluated by bootstrap analysis in 100 replicas. Conclusion: The article shows the possibility of modern methods of molecular genetics and bioinformatics use to assess the ecological status of water bodies. The identification of organism species by molecular genetics and the appropriation of a saprobic indicator using bioinformatics method provide a new modern tool to assess the ecological status of water bodies and monitor water bodies. Further research in this direction will be carried out for other hydrobionts.
