Floodplain wetlands are considered as biologically sensitive habitats and predicted to be the most
impacted through climate change. They form an important fishery resource in West Bengal, India.
Analysis of Indian Meteorological Department (IMD) derived climatic data has revealed a unanimous
warming trend (0.18–0.28 C) and decreasing rainfall (135.6–257 mm) among the studied districts
(North 24 Parganas, Nadia and Kolkata) of West Bengal over the last three decades. Four floodplain
wetlands under cooperative fisheries management were studied during February 2015 and
December 2015. Data were collected through a structured communication process involving multiple
interviews through multiple rounds of surveys and also from secondary sources. Six climate smart
fishery strategies could be identified, namely Temporary pre-summer enclosure, Submerged branch
pile (Kata) refuge, Autumn stocking, Torch light fishing, Deep pool (Komor) refuge and Floating
aquatic macrophyte refuge fishery (Pana chapa). Few of them are capable of serving as conservation
tools by providing refuge during summer or water stress and maintaining base stocks in the wetlands
for recruitment in the following monsoon season. The present paper discusses the climate smart
nature of these pre-existing indigenous fishery strategies. These strategies need to be optimized and
may be used for adoption of sustainable climate smart fisheries management in floodplain wetlandsFloodplain wetlands are considered as biologically sensitive habitats and predicted to be the most
