The fisheries and livestock sectors are two major pillars of Bangladesh’s economy, and more than 10 million people directly depend on these sectors for their livelihoods. These sectors are also important for food, nutrition, income, export earning, draft power, biofertilizer, and transport. The fisheries
sector is vibrant, contributing to about 20 percent of the agri- cultural GDP, while the livestock sector contribution is around 12 percent. These two sectors provide the major dietary protein. During 1994−2005 the food from animal origin increased from 76 to 113 gm per capita per day. About 63 percent of animal protein supply in the diet of the people of Bangladesh is obtained from fish.
