Fish producers in Cooch Behar district of West Bengal, India are increasingly shifting to intensive fish culture to meet market demand. To lower culture expenditure, fish farmers generally utilize locally available ingredients for feeding the fish. Feeding of Indian Major Carps (IMCs) like rohu, catla and mrigal are largely ad hoc, and differ from one production centre to another. To formulate the best possible food for IMCs under culture conditions in Cooch Behar district by using different diets incorporated with locally available ingredients, a two year experiment was carried out in outdoor farmer’s ponds in four villages namely, Kalakata, Gitalda, Matalhat and Maruganj of Cooch Behar district. The book details the findings of the work along with a discussion on how the culture of IMCs can be improved in the region.
