摘要：We surveyed the fish farmers of five states, viz. Andhra Pradesh, Karnataka, Gujarat, Odisha and West Bengalof India for adaptation and mitigation strategies of climate change impact in freshwater aquaculture. In monsoonperiod especially when the cyclone occurred, overall 9% fish farmers responded regarding fish migration from onepond to another pond. Sometimes entire stocks washed out due to heavy floods. Overall 23% farmers respondedabout water quality deterioration and contamination due to unforeseen weather conditions mostly during rainyand summer seasons. Disease incidences during the winter seasons especially Argulus infestation was reported by42% respondent. About 37% farmers in Andhra Pradesh, West Bengal and Odisha expressed that farming systemswere damaged and lost all the fishes because of extreme events like flood, cyclone etc. They also reported thatall operational cost increased every time in re-construction of ponds due to floods. The farmers tried to mitigatesome of the problems encountered due to climate change. Overall, 43% of farmers are pumping freshwater tocool down the temperature of fish culture ponds. Some farmers applied oxygen tablets during higher summer.When there is low rain fall, 60% farmers maintain water level by pumping in water from their bore well. While75% farmers never experienced any disease problem, 25% reported such incidence, among them 50% apply limein case of appearance of disease symptoms. In case of drought, 25% of the farmers reported that they have madeearly harvest, irrespective of the fish growth, others never stock the ponds. In case of flood, 48% of farmers usedto prevent fish escape by using mesh like structures in pond bunds to prevent fish escape, while 16% pump outwater using their pumps.
