Demonstration of climate resilient fisheries(CRF) at Panchpota and Media wetlands, West Bengal
30th April, 2022
Climatic variability and its consequences have intensified across the world during the last few decades impacting the food production, income, livelihood and nutritional security of people. The global surface temperature has increased faster since 1970 than in any other 50 year period over at least the last 2000 year as per IPCC 2021report. In the last two decades of the 21st century (2001-2020), the rise in global surface temperature was +0.99oC revealing the pace at which the climate is changing in recent decades. Climate change will alter the water temperature, water levels and flow of the inland waters, and it will exert substantial impacts on aquatic ecology and fisheries. Inland open water resources are important resource for fish production in India which are vulnerable due to overfishing, pollution, loss of biodiversity, invasion of exotic species, sedimentation and habitat destruction. The impact of climate change alongside the anthropogenic factors and other stressors render these ecosystems more vulnerable leaving the income and livelihood of millions of fishers at stake. Major impacts on inland open waters include change in water flow, altered hydrology, thermal stress, occurrence of extreme events, habitat degradation, change in breeding and spawning behavior, and life history traits, leading to adverse effects on aquatic biodiversity and fisheries.

Climate change is causing devastating effects on inland open fisheries especially floodplain wetlands viz. declining natural fish fauna, altering the breeding phenology, increasing the vulnerability of ecosystem and dependent fishers. In this context, it is imperative to develop and demonstrate climate resilient adaptation strategies and sensitize the fishers for increasing their adaptive capacity in the context of changing climate. Pen culture is a type of enclosure culture and has the advantage of providing natural food base for the fish. The institute has undertaken Climate resilient pen systems in wetlands of West Bengal, Assam and Kerala for farming of fish and shellfish and conservation of SIFs. The climate resilient pen systems (CRPS) and cage system (CRCS) have high tensile strength HDPE net material, provision to withstand flood, wind action and is used for culturing resilient indigenous species. Stocking of climate resilient indigenous fish species are encouraged in pen and cages to adapt to changing climate.।

ICAR-Central Inland Fisheries Research Institute, Barrackpore, West Bengal organized a two-day awareness campaign “Climate resilient inland fisheries” and stocking programme in climate resilient systems as a part of Kisan Bagidari & Azadi Ka Amrit Mahotsav from 29th to 30th April, 2022 at Panchpota and Media wetlands, North 24 Parganas, West Bengal under the NICRA project. The campaign includes the installation of climate resilient pen culture system (CRPS), distribution of high protein feed for fish growth, stocking of climate resilient indigenous fishes in CRPS and cages and meeting with the stakeholders to educate them about the climate resilient strategies and adaptation technologies. The national campaign and demonstration were conducted under the overall guidance of Dr. B. K. Das, Director, ICAR-CIFRI, Barrackpore.

Dr. Uttam Kumar Sarkar, PI, project NICRA; HoD, RWF division, ICAR-CIFRI coordinated the campaign and highlighted the effects of climate change on wetland fisheries and various mitigation and adaptation strategies. Three CIFRI HDPE Pen (0.1 ha each) were installed at Panchpota wetland and six CIFRI GI Cages were installed at Media wetland. Around 90 kg Labeo bata, Puntius sarana and Ompok bimaculatus seeds were stocked in climate resilient pen system at Panchpota and climate resilient cage system (CRCS) at Media and 3 tonnes of CIFRI CageGrow Feed was also distributed during the programme. The meeting and demonstration programme were co-cordinated by Dr. Suman Kumari, Shri. Mishal P and Dr. Lianthuamluia Scientists of ICAR-CIFRI, and project staffs and research scholars of the project. A total number of 70 fishers have attended the programme.
