    Abstract

    With the total fish production of 10.8 million tones today, its demand in India has been increasing consistently with the increased 'income of the consumers and their growing health consciousness. It is estimated that to meet the domestic demand the country requires additional 10 million tons offish by 2050. To maintain the growth pace of the sector, the fisheries and aquaculture, therefore, need to tackle the challenges of resource competition, water scarcity, climate change, growing disease problems and several other technical, environmental and social issues. Climate change impacts such as variations in rainfall and temperature, drought, extreme weather events and changes in oceanographic features, affecting the fisheries resources, farming conditions, fishery distribution and habitat changes, have been found to be quite significant and alarming. Therefore, identification of the vulnerabilities associated with climate change events on fishery resources and coming up with resilience measures as well as adaptation strategies are urgent necessities. An attempt has been made to collate and synthesize information on future climate change impacts and challenges posed on the fisheries and aquaculture sector and explain various mechanisms for addressing these challenges. Immediate necessity - - of developing an action plan to mitigate the impact of such climate change scenario in fisheries and aquaculture has been emphasized. Further, the paper also envisioned the use of Representative Concentrafion Pathway. (RCP) scenarios (in 2030,2050 and 2080) developed by the IPCC in concert with predictive modelling techniques to gauge the intensity of future changes likely to occur in the fisheries sector.
