The commonly known Meni or Bheda fish in Bangladesh, Nandus nandus (Ham.-Buch.), is an important fish-food of high nutritive value in South Asian countries. The natural population of this fish has been declining rapidly due to some parasitic infections, which has escalated due to the lack of scientific management, anthropogenic disturbances, unhabitable water quality, and such related factors.
