What is River Ranching?

River Ranching is a form of aquaculture in which a population of a fish species (such as salmon) is held in captivity for the first stage of their lives. They are then released, and later harvested as adults when they return from the sea to their freshwater birthplace to spawn.

River ranching programme was introduced as special activity under the ‘Pradhan Mantri Matsya Sampada Yojana (PMMSY) scheme to augment and enhance fish production and productivity by expanding, intensifying, diversifying and utilizing land & water productively.
