Abstract:
The purpose of the study is to identify various climatic change risks encountered by fish farmers while doing freshwater aquaculture in the unmanaged ponds of district kaushambi Uttar Pradesh. The various climate change risks which were faced by rural farmers of Kaushambi are water quality, flooding of ponds, less rain, heavy mortality of fishes, planktonic collapse, long dry spells, disease outbreak, destruction of embankments etc. The study also includes the measures to encounter these risks. To maintain the quality of water the farmers have used lime, manure, alum, KMnO4, salt and exchange of water. To control the flooding of ponds the farmers raises embankments by bamboo fencing with net. They have filled their ponds with pumps from canals / rivers and tube well water to face the problem of less rain and long dry spells. To avoid the heavy mortality of the fishes they have used early harvest, liming, shading and water movement by beating of water for oxygenation. To overcome with the planktonic collapse the farmers have used cow dung, gobar gas slurry, use of khari, choker in the water and exchange of 50 percent water. To control the disease outbreak the farmers have adopted lime, KMnO4, medicines, neem leaves, banana stem etc.
