Labeobrabus species flock is the unique species and the species richness were declined year to year due antropogonic and natural problems.Therefore, this species should be conserved by developed methods which enhance the species sustainable reproductive performance.Finally, I recommend that, development and environment should be harmonized in order to create prosperous biodiversity, environment and improved feed nutrition for food insecure societies.
