An initiative of Fish Diversity Restoration: CIFRI ranched 2.2 lakh scampi seed in the Ganga Upstream under NMCG Programme.

The National Ranching Mission III, spearheaded by the National Mission for Clean Ganga (NMCG), has initiated a giant leap toward ecological restoration and biodiversity protection. Under the leadership of Dr. B.K. Das, Director of ICAR-Central Inland Fisheries Research Institute (CIFRI), this initiative addresses the challenges posed by the Farakka Barrage, along with niche exploration of potential solutions, and implementing the most effective one pertinent to the revival of the Ganga River’s aquatic ecosystem.

The Farakka Barrage, while essential for irrigation and navigation, has significantly disrupted the natural migration of key aquatic species like scampi (Macrobrachium rosenbergii), a freshwater prawn native to the Ganga River system. This obstruction has impacted scampi populations, affecting their breeding cycles and contributing to biodiversity loss.

To mitigate this, Team CIFRI in collaboration with 35 local fishers, have released 2.25 lakh post-larval (PL15) scampi into the upper stretches of the Ganga River. This effort aims to eliminate the dearth of scampi prevalence, along-with restoring the scampi habitation, support traditional fishing livelihoods, and enhance riverine biodiversity. The mission stands as a beacon of sustainable ecological intervention, merging scientific expertise with community participation.

“Scampi are indigenous to the Ganga and are key to sustaining its ecological balance”, reiterated Dr. B. K. Das. “The barrage disrupted their migratory patterns, leading to a decline in their population. This ranching initiative is an effort to re-establish that natural balance”. He also emphasised the negative impact of using zero mesh size nets, which indiscriminately trap juvenile and non-target species, further harming aquatic biodiversity.

Over the past eight years, CIFRI has delved in the efficacy of the river ranching programme focusing on IMC (Indian Major Carp) and in continuation to that other species like Bata, Sarana, and now Scampi, reflects a multi-species approach to river restoration. By restoring traditional fisheries, the initiative aims to rejuvenate the economic prospects of local fishers and communities that have historically relied on the Ganga for their sustenance.
